2. ## Hidden information in local card game

HI there, I'm currently working on a 2-player local card game and have run into a problem concerning hidden information. As in most other card games, I want to keep the cards each player has, hidden from the other player, but when you only have one screen this turns out to be more difficult than you think. I have multiple ideas how to solve the problem, but none of them really seams to be very elegant: 1. Turn around the cards, for the player that currently has to make a turn: This is the first idea that came into my mindt, but it also has a big problem: The other player isn't allowed to look at the screen while the other player is performing his turn. This seems unituitive because your opponent might want to think about his next move, or even worse, might need to respond to your actions depending of the design of the game. It also seems very unfun, to always make sure the inactive player turns around before making the next turn. 2. Encode the cards of each player: My second idea was to let each player choose a seed, to encode their cards. This would work like the following: Each player chooses a seed which then encodes each players cards (gives them random ids, according to the seed) The game would then only show the id's of the card available to the player. The second step would be to create a small phone app, where you could enter the seed and then display your cards by entering the ids shown on the main game. The problem with this would be that each player needs to keep track on his phone which cards he has, which he just played, etc.. This would cause the player to effectively do each turn twice because after playing a card on the main game screen he would need to manually remove it from his phone app. 3. Create a networking system that sends the game information to each players phone: Pretty much the same deal as above, only that you get rid of all the manual work of seed picking and updating the cards in your hand. A downside for me, however is all the code needed for networking to manage this stuff. For now I rather prefer to stay away from the networking aspect, as my project is complicated enough for now. 4. Scrap the idea of the local multiplayer and go full online mode (like Hearhtstone): Same deal as above, would need lots of networking. As you can see none of the solutions are very practical (if you want the project to stay local and don't use any networking). Do you have any ideas how you could solve this problem more elegant without overcomplicating the hole process of getting the information to the player and breaking the gameflow to much? Thanks in advanced for your help!
3. ## 2D To The Capital 2 is now live on Steam!

To The Capital 2 is a game in the genre jRPG with classic turn-based battles in which you have to travel together with four heroes visiting a lot of cities, dungeons, mysterious places and fight with various bosses.It took almost 2 years to develop and finally we have reached this important event as the release of To The Capital 2!Big thank you to everyone who has followed our project. I hope our game will give pleasure to fans of the genre of jRPG, and beginners in it.
4. ## Performance of D3D12 and Vulkan

Maybe you are right about bindless and multithreading combined, I haven't thought about it too much in a while. Although we already have texture arrays in d3d11, I don't see why we can't relax the requirement that they be all the same format and size, and just let us index an array of textures in a shader. I think OpenGL has bindless texture extension. I don't see how this causes a multithreading issue for SRVs. Seems multiple threads could reference a read-only texture resource just fine when building a command list.
5. ## float or double for my vertices / normals?

There's a reason I quoted two numbers in there instead of 1. You can multiply the whole thing by 10 if you like to get a safe "10km to 1cm detail" range. Fixed point 32bit was mentioned where obviously you can't use int(1) = 1m and still have millimetre details... So it holds that the same arbitrary unit techniques can obviously be used with float as well. Almost everyone works in meters and the other scientific units by default though, so I quoted my rules of thumb using those units and human scales. Did you really just assume I was telling you to store vertex position as meters in an integer and that will somehow preserve sub-milimeter details? And then repeatedly try to point out that this isn't true?

Awesome @All8Up, that worked perfectly. Many thanks!

9. ## Pygame - alternatives?

You should have a look at HARFANG 3D, that is a full C++ engine with a Python API (just import harfang and you take it from there) I'll let you have a look at the samples below and try it for yourself. Just feel free to contact me if you have any question, I'll be glad to help (I work for the company that develops HARFANG). A mini "ace combat" game, all done in Python : A snooker simulation, in full rigid body physics, all done in Python : and a couple of code snippets, including VR : https://github.com/harfang3d/vr-python-quickstart
10. ## My first OST | Feedback please

Maybe you're right. Because I'm trying to meet expectations, but i think this is not my lvl now.
11. ## Creating a global thread

The temporary is already an rvalue, so what's the std::move for? (And the lambda also isn't useful, if you don't need the capture.)
12. ## My first OST | Feedback please

Gotcha. In that case - why not just have the audio by itself? Tying it to the Star Wars visuals definitely gives an expectation.
13. ## My first OST | Feedback please

Thx a lot, man! Yeah, i have some problems with melody, because i usually used a voice for that, but in soundtrack voice doesn't need. I try to upgrade my tracks with your opinion. In Star Wars this is my first video music experience. And now i understand that this is big fail. Hope for next time i was more prepared. And again, thx so much!
14. ## My first OST | Feedback please

Destiny - Man, this is a fun track! I'd watch out for your low to highs balance here. I'm getting a LOT of highs but not much lows at all. This is making the mix feel tinny and thin. With the emotional, epic vibe you're building, there's PLENTY of opportunities here to make some big, large impacts. I really like the moment at 2:27 but I'd be careful about the rhythms here. With such a slow attack on the long(er) strings, it can make things feel out of time. The ending should be built up to be MUCH larger. The last few drum hits just don't do it justice at all. And consider a cymbal roll into that final hit with a nice, long reverb tail. It's a fun track but there's still a lack of a main melody. Not saying that's a problem but just be aware of it. The name fits - certainly feels like an epic, fates-driven song. Nice job, overall! Star Wars - You have to be really careful when writing to picture. You want to make sure your music matches the visuals perfectly in both terms of rhythm and vibe/mood. Unfortunately, I feel neither are matched up well in this video montage and your music. I would go back and look for key moments you want to hit and work out ways to build up the music (or have it suddenly drop out) to better fit the pacing of the visuals. Then also do a better job of establishing the vibe and mood you want the music to express. This music feels way more melancholy than what the visuals and the plot of The Empire Strikes Back presents. Also some of the same production tips I gave for Destiny apply here too. Hope that helps! Nate

16. ## League of Legends implementation design

All champions in League of Legeds are 3D models, animated with skeletal animation. You can see the actual models in lots of viewers, even online - like here: https://www.fanbyte.com/features/league-of-legends-model-viewer/#W1swLDAsMCwiNDAiLDMsNV1d It doesn't include particle effects at all, but basically you can see that there is just 3D model and simple skeletal animation. Not just for movement, attacks, but even for death (which points out that there is no rag doll physics involved, at all). The maps are also 3D, hand textured - the look is quite acceptable. They often use large polygons with hand painted image - especially for backgrounds around the map. They don't really use many effects (they used even less back then), I believe their goal is and always was to target even slower hardware (I was running it on integrated Intel GPU back when I was on university - and the performance wasn't bad). Some basic physics computation will be involved - for Ziggs abilities F.e. (bouncing bomb) - but they don't really use any rigid body dynamics, or cloth physics at all. Some animations are baked and look like physics simulation (collapsing environment on Howling Abyss for example). This will be just assumption on my side - but I believe Riot uses navmesh to implement character navigation on map (therefore when you move anywhere, your character immediately knows the path how to get there. Other champions can then be implemented by other agents on the navmesh, and so does minions (and abilities). You then have to avoid/block with other navmesh agents when going along the path. Why do I think it is used? Try blocking minion wave with your character, they do have some collision avoidance implemented. Also this tends to easily allow some characters to ignore the barricade (like moving through minions), easily implement 'Flash' ability, etc. Riot hosts their own servers, each of the 10 regions uses different location. What do you consider affordable budget? For development I'd dare to say that single small virtual server is enough (possibly multiple to implement load balancing) - these things are extremely cheap (I pay about $50 per year for one of these, and you can get cheaper depending on your requirements). As for live servers, this will depend on the amount of people that will play your game (your budget can easily go anywhere between$20 per month, to \$20k per month and beyond). Using cloud services like AWS can be a huge advantage here, because you can scale them based on your requirements (start with small one, and when picking up more players you can upscale), this should work unless your game is simply too big, and it most likely will work for that scenario too, although ... at some point buying your own hardware and housing it will most likely be cheaper.
17. ## Performance of D3D12 and Vulkan

You don't get bindless texturing or efficient multithreading without manual memory management and manual resource barriers. I suppose some people may see memory management as a feature rather than a tax, but resource barriers are nearly always a tax. But if you want the ability to do bindless or efficient multithreading, the app's the only one who has enough information to be able to do it -- in order for the driver to do it, they'd need to know what you're referencing (defeated by bindless) and when (defeated by multithreading).
18. ## Performance of D3D12 and Vulkan

DX12 makes sense for large teams or companies that make engines that can optimize for each GPU type. It's not worth the development cost for small companies or smaller 3D projects IMO. I hope they eventually release some sort of DX11++ that supports the ray tracing API, bindless texturing, PSOs, and better multithreading, maybe even manual resource barriers. Not really interested in manual memory management (maybe make this optional--let driver do it or do your own). I think they could have solved a lot of the CPU draw-call overhead problems without going so low-level.
19. ## Alternative names for fantasy classes

I like the idea of finding new names and say take it a step further and abandon the high-fantasy setting, keep the same concept, slow speed tank units that deal heavy damage, mid range units with more speed and less damage, and of course the squishy special skill users. The basic concepts of strategy the SRPG genre are rooted divide all military combat units into 3 groups,infantry, artillery and cavalry. Each has its' strengths and weaknesses and is effective against one while being vulnerable to the other. It's easy to default to knights, archers and mages when translating this concept to video games because that is the standard for so many of the best SRPGs, but at it's core it's just a basic grid based rock, paper sciscors game. If you have something awesome that will stand out like a story that absolutely needs to be told in a Tolkenesque high fantasy setting or a bunch of assets made and work done on a fantasy. Of course you should try and find a game play mechanic to make it stand out but I think a different story and setting will do just as much to make you stand out. Take for example "Shadowrun", it took the basic table top mechanics of "Dungeons and Dragons" then changed the settings and made their own distinctive world out of it. There are the same basic concepts, magic, orcs, fairies, dragons, but it's in a cyberpunk setting and set in alternate future dystopian versions of real world cities. The series has managed to stand out and have longevity compared to the countless other D&D clones of the time and has been around for about 30+ years. First, decide on a setting. If you have your heart set on high fantasy medievil we can work from there but see if you can't come up with anything else. It doesn't have to be Shakespeare, it can just be the Shmoobles wanting to fight the Schmobbles because they took all the Schmoopty, the important thing here is where is this happening?
20. ## Creating a global thread

you're going to need a std::move in there like All8Up posted.
21. ## C++ League of Legends implementation design

Hi All, I want to make a game similar to league of lengends but I am not able to decide certain implementation factors that I will eventually put in my code. 1) Is the game world full 3d or 2d? I am confused here because there are videos on youtube that show first person LOL and there are video captures that shows full 3d perspective view of characters. Is it 3d but the camera is fixed at angled top view? Is it not a waste of polygons of your game objects are 3d but you get to show them from one fixed global camera? 2) Is there any physics simulation involved? It looks like interacting players have fixed animation and it does change per map position. If there is some, how of physics is involved? 3) How collision detection is implemented? I believe characters just block each other and dont’t animate while trying to be at one same coordinate. They interact only throug auto(which is click and play) or abilities(click and play). 4) If my multiplayer architecture is client server, then where can I deploy the server? Do lol have dedicated high performance/ load balancing server computers for each continental areas? Are they self hosted or hosted through aws/cloud services? Is it possible to setup self hosted server application with affordable budget? How much?

23. ## Crypts of Death: Free Android mobile RPG

It's a really fresh and interesting take on the rpg genre! I really like it Hope to see more updates in the future.

25. ## float or double for my vertices / normals?

If I try and sell you something for 100 but say I will take 10, then you ask me if I am talking about dollars, I would say "don't get hung up on the units, I'm talking about magnitude".
26. ## Ideas for Platformer Game

Thanks for the idea man! I think that's a really cool idea. I'm planning out what choices you make right now, and that looks great.
27. ## float or double for my vertices / normals?

I think you're getting hung up on the units, when @Hodgman is really just using them as an example to talk about magnitudes of scale. He's saying that if you're covering around 7 orders of magnitude or less (i.e 10km to 1mm, or 10m to 1 micron, or 1AU to 10 miles, or whatever) then you're fine with a float.

29. ## float or double for my vertices / normals?

I think you did. You can put a whole planet in 1 unit or you can fit a grain of sand in 1 unit. It depends on the game. There is no such thing as kilometers or millimeters inside a computer. It matters with scale when exporting/importing meshes from DCC tools to game engine but also with floating point accuracy inside the game itself. Without defining a base unit size you can make no assumptions. A unit is not a size. Unit math is what causes floating point accuracy errors. You must define the size of a base unit to make real world comparisons thus my observation to Hodgman's assumed unit size... "You can't assume what size the units represent and it does matter when using your guidelines listed. "

Hello youngster It is not possible for a single person to create something that matches the best game engines. Unity employs 2000 people, they've been developing for years. The idea that you can do that on your own is nonsense. The good news is that you don't have to; people confuse the difficulty of making a game engine with the difficulty of developing a game from scratch without using a game engine. This is possible; although not sensible (I'm doing it because I want to, not because I think it's a better approach). Realistically the best way to make games is to just use an existing game engine. Nope, this is mostly just Game Programmer snobbery; however, there is a filter effect. The minimum skill level for entry is higher, which creates a slightly false impression of overall difficulty, but there are top class programmers in basically every field taking on remarkable challenges. JavaScript is a god awful excuse for a language; please don't confuse it with modern languages such as C#, Rust, or Python. C++ continues to be the best widespread language at what it does and will be around as a major legacy language until long after you and I are retired. However, the need for maximal performance is ever diminishing and, realistically, there's no good reason to favour the C++ of Unreal over the C# of Unity or vice-versa beyond personal preference or considerations such as existing code, or favoured libraries to use with it. Both are easily capable of powering AAA quality games. Outside of games, C++'s diabolically poor Windows development libraries are an issue; C# is simply better for any kind of Windows UI stuff. No. The difference in performance is marginal and far smaller than other concerns.

32. ## Ideas for Platformer Game

Perhaps you could give the player a choice whether he wants to abide by the rules or take a more riskful path, e.g. getting a job or do some shady business. That could open up a lot of possibilities.

Using a game engine like Unreal or Unity you can get to an acceptable result as fast as a day of tutorials get you. Making a game engine by yourself is a long term but interesting job I do for last 6 years in C++ now. I worked part time at it in my spare time (that is nearly 1 1/2 years of work in fulltime I think) and had an iteration process where I throw code away and started completely from scratch but at least it was/is worth it if you don't want to release a game in a couple of months with that. There are a lot of topics you need to get about and even more management needed as I posted some answeres here related to engine architecture. I'm on the track of doing anything on my own so using no third-party libs and even prevent using the STL is my goal and I got very far with that. I've seen a lot of engine projects out there in the wild and most of them just threw some libaries from all arround the net together and called that a game engine while others like Urho3D (free and open source) made a good first look and even Cry Engine and Unrealare open source these days. Feel free to take a look at them. It is but because of the debugging capabilities. You won't see a mesh laying on the GPU as you see a buffer you allocated in your 'normal' program and even Shader programming is a world of itself. It depends; if you are using C++14 + with all that fancy shiny language features, it is bloated of stuff you won't need for a game/engine except for a very slow and memory wasting one. SmartPtr dosen't do memory caching and dosen't prevent memory from fragmentizing while Lambdas are a thing to avoid unless you really know what you are doing. On the other hand C++ has more capabilities of low-level handling than other languages like Java or C# and this is what makes it such powerfull. I love playing with raw pointers and using templates while in our coding guidelines we highly recommend the C++ 99 standard and rarely use some C++ 11 features to keep anything compatible. Crysis is almost obsolete and you should avoid using Cry Engine. Unreal and Unity are both capable to run well on limited platforms if you know what you are doing. They don't keep ya away from wasting CPU and memory

Very, very nice! I love the art style, and how you managed to make it look great with very simple graphical means. However, the thought that you wrote it in JavaScript hurts in my brain...why don't you use TypeScript? I mean, on the other hand, this makes it even more impressive, but I wouldn't want to put that pain on me.
35. ## Ideas for Platformer Game

He's just a normal man, in a normal world. You'll get to decide things like who he marries, some of his friends, college or no college, things like that. The idea is that the levels are supposed to represent the difficulties of navigating everyday life, with any mistake potentially destroying your life(restarting the level)
36. ## Ideas for Platformer Game

So tell us a little more about Harold Where does he live? Is it a fantasy world or more like real life? What's his goal? What other characters are playing a role? You have to define your world at least loosely otherwise you may end up with something that feels tacked-together. I could say here it would be fun to swing on a rope but perhaps that doesn't make any sense in your game. Don't confuse this with elaborate storytelling, but just use it for yourself as a general guideline for things that happen in your game. Hope this helps.

It's a pixel art game, where you are playing through the life of a man named Harold. You can make rpg-esque "decisions", more difficult decisions(AKA going to college) having more difficult platforming required. There will be 15+ endings based off of your decisions you make in game.
39. ## float or double for my vertices / normals?

No. It's just a proportion. The order of magnitude is the same whether you talk about meters, kilometers, yards or whatever. So if you have a map of 10 km with the minimum detail is about 1mm, it is the same if you have a 10 meters map and a detail about 1e-3mm and so on. Or did I understand wrongly what you told ?
40. ## Ideas for Platformer Game

Try to create a theme and some background story for your game. That will give you some context from which you can extract ideas. People would also be able to give you more coherent suggestions.
41. ## A lack of Raypunk / Pulp Sci Fi games?

Looks a bit like Phantasy Star. If you wanna make a game with artsy backgrounds i recommend a (2D)-shooter or platformer. ps, Age of Wonders isn't a 4X-game(on soil) though it shares some similarities since they re both empire-builders.
42. ## Ideas for Platformer Game

I'm building an innovative 2d platformer game, more on that later probably. I've created basic mechanics, some basic enemies, wall jumping platforms and the like.

BTW, the game is already available on itch.io for free! Right now, we are discussing about new technologies to include in the gameplay (turrets and drones, maybe). Feel free to participate in the conversation in our Discord Server.

Should objects be measured on the CPU, GPU or on the screen? You can't assume what size the units represent and it does matter when using your guidelines listed.
45. ## Tech challenge - how to avoid ball mishits? (Unity)

Use a Fixed Time Step not Variable if the speed of the ball is causing missed collision. Don't use Update() for anything physics related, that is why you have FixedUpdate()
46. ## Gameplay Tech challenge - how to avoid ball mishits? (Unity)

hi all, just wondering if I could get your tips or insight on a specific gameplay and animation question I've had for a long time: For tennis games and other games involving hitting fast moving objects, what would be a good way to avoid mishits like in this video? (Far side 0:50s and 0:58s) (watch in .75 or .5 speed for even more clarity) This is quite a common visual bug for tennis games as I assume the devs didn't have time to polish, but I want to make sure I plan and code for my tennis game to avoid this kind of blemish. I'm assuming the fix would involve some kind of IK solution and maybe target matching to get the hitting animation to line up with the correct hit "pose". Any advice for a Unity beginner like me would be super appreciated 😃

In this pong esque arcade game, you collect blue balls to get as many points as possible while weaving through red balls. Yellow balls and green balls will you do good, but be wary of the black balls!
