So here we go (again), and before i start: i remember i recently skimmed over an article that talked about cross platform technologies and compared different engines, do you know of such an article on gamedev? I'm interested in a game engine(free or paid) that can run on as many platforms. I've looked at Unity and it looks nice(only pc, mac, iphone, wii), ogre, C4. What do you recommend? I certainly need iphone,pc,mac, maybe linux and one or two consoles.

What exactly do you need the engine to do for you?


Well, i need it for some indie projects i'm going to pursue. First of all i need it to be cross platform to be able to ship on as many people as i can. Also i need it to be scalable(so it must be able to do advanced precomputed lighting as well as handle multiple dynamic per pixel lights with shadows). Physics is a key topic, it must support pretty decent physics. Also it must have a great community that can help when stuck on different issues. That and a clean design that is also powerful and easy to learn and develop with. I need it to help me develop fast not stand in my way. Up until now Unity 3D seems a good choice.

Basically, you want it to be perfect. There is no such thing.


QFT. Every engine satisfies some strict subset (possibly the empty set) of all possible requirements. I'd like my engine to come with a pony, too ... but that's not going to happen.

As always, I hate to sound like a jerk when I say this, but... Given your apparent skill level, experience and budget, it appears as though your post may be a brilliant joke/troll. If not:

1) I apologize.
2) The fact that it can be mistaken for one should tell you something. (Hint: reconsider whatever it is that you're pursuing).

My first response was going to be gamebryo, as it runs on all the main consoles and Windows/Linux, but...

If you make a game that can run on both the iPhone and the XBox, then it's going to be a crappy game on at least one of those platforms...

You really have to make two or three different versions of your game to support that many platforms. Some companies will split a game into the hand-held version (iPhone/PSP/DS), the last-gen version (PS2/Wii) and the next-gen version (PC/360/PS3). Each one of these versions is basically a different project, and within that project you might have multiple SKUs for different platforms.

If you don't have the budget for that, then I'd stick with Unity and do what you can to design the game to work with mouse OR touch-screen OR motion-stick...

Yeah deffinately, aiming a game at both iphone and 360, and expecting to use the same codebase for each is kind of rediuclous.

It could work for a very small subset of games (turn based, minimal graphics, minimal CPU) but meh, while technically possible i doubt its what you are shooting for haha.

Various platforms have different quirks that change how your game has to be designed at the very core:

Wii - it has a mouse like pointer with 2 buttons so it can be a good platform to share PC platform code with. It is very neutered in CPU/GPU though compared to other platforms. Not a lot of RAM, no internal hard drive. crappy multiplayer support. It can do arcade style controller input though as well as the pointer style input.

360 - powerful CPU and GPU, lots of RAM. Internal hard drive. no point and click interface (you can emulate it VERY crappily with the controllers analog sticks, etch a sketch style)

PS3 - much like 360 but not as much RAM, special considerations for CPU too.

Iphone - touch and click interface, but very neutered CPU and GPU since it's handheld. No way to really do arcade style input (ie controller).

DS - more neutered than iphone in CPU/GPU/RAM. touch and click interface, also arcade style interface.

So, tell me how you are going to make a game that even works for all these platforms from a DESIGN point of view?

It isn't (really) possible, so step #1 of your cross platform requirements, the failure is your design :P

get past step 1 before trying to get to step 2!

I believe Torque does all of those platforms. Unity can deploy to most of the ones you listed.

How about Gamebryo's Lightspeed?


Definetely have to give it a try!

I'm interested in such an engine because i want to use it, let's say to make a title for two-three platforms and another one for the other more weak platforms and not have to learn two engines for this task. I figured it would be easier to stick to the same technology. :D

Have you looked at OGRE? http://www.ogre3d.org/

It is mature, cross-platform (Windoze,Linux,Mac), also supports others devices as well. Also does OpenGL or DirectX. This usually helps a lot: it's free. There is a big iPhone port going on right now.

Check the forums: http://www.ogre3d.org/forums/

      Good day,

      I just wanted to share our casual game that is available for android.

      Description: Fight your way from the ravenous plant monster for survival through flips. The rules are simple, drag and release your phone screen. Improve your skills and show it to your friends with the games quirky ranks. Select an array of characters using the orb you acquire throughout the game.

      Hello fellow devs!
      Once again I started working on an 2D adventure game and right now I'm doing the character-movement/animation. I'm not a big math guy and I was happy about my solution, but soon I realized that it's flawed.
      My player has 5 walking-animations, mirrored for the left side: up, upright, right, downright, down. With the atan2 function I get the angle between player and destination. To get an index from 0 to 4, I divide PI by 5 and see how many times it goes into the player-destination angle.

      In Pseudo-Code:
      angle = atan2(destination.x - player.x, destination.y - player.y) //swapped y and x to get mirrored angle around the y axis
      index = (int) (angle / (PI / 5));
      PlayAnimation(index); //0 = up, 1 = up_right, 2 = right, 3 = down_right, 4 = down

      Besides the fact that when angle is equal to PI it produces an index of 5, this works like a charm. Or at least I thought so at first. When I tested it, I realized that the up and down animation is playing more often than the others, which is pretty logical, since they have double the angle.

      What I'm trying to achieve is something like this, but with equal angles, so that up and down has the same range as all other directions.

      I can't get my head around it. Any suggestions? Is the whole approach doomed?

      Thank you in advance for any input!

      Hello,
      without going into any details I am looking for any articles or blogs or advice about city building and RTS games in general. I tried to search for these on my own, but would like to see your input also. I want to make a very simple version of a game like Banished or Kingdoms and Castles,  where I would be able to place like two types of buildings, make farms and cut trees for resources while controlling a single worker. I have some problem understanding how these games works in the back-end: how various data can be stored about the map and objects, how grids works, implementing work system (like a little cube (human) walks to a tree and cuts it) and so on. I am also pretty confident in my programming capabilities for such a game. Sorry if I make any mistakes, English is not my native language.
      Thank you in advance.

      Hey,
      So I'm currently working on a rogue-like top-down game that features melee combat. Getting basic weapon stats like power, weight, and range is not a problem. I am, however, having a problem with coming up with a flexible and dynamic system to allow me to quickly create unique effects for the weapons. I want to essentially create a sort of API that is called when appropriate and gives whatever information is necessary (For example, I could opt to use methods called OnPlayerHit() or IfPlayerBleeding() to implement behavior for each weapon). The issue is, I've never actually made a system as flexible as this.
      My current idea is to make a base abstract weapon class, and then have calls to all the methods when appropriate in there (OnPlayerHit() would be called whenever the player's health is subtracted from, for example). This would involve creating a sub-class for every weapon type and overriding each method to make sure the behavior works appropriately. This does not feel very efficient or clean at all. I was thinking of using interfaces to allow for the implementation of whatever "event" is needed (such as having an interface for OnPlayerAttack(), which would force the creation of a method that is called whenever the player attacks something).
       
      Here's a couple unique weapon ideas I have:
      Explosion sword: Create explosion in attack direction.
      Cold sword: Chance to freeze enemies when they are hit.
      Electric sword: On attack, electricity chains damage to nearby enemies.
       
      I'm basically trying to create a sort of API that'll allow me to easily inherit from a base weapon class and add additional behaviors somehow. One thing to know is that I'm on Unity, and swapping the weapon object's weapon component whenever the weapon changes is not at all a good idea. I need some way to contain all this varying data in one Unity component that can contain a Weapon field to hold all this data. Any ideas?
       
      I'm currently considering having a WeaponController class that can contain a Weapon class, which calls all the methods I use to create unique effects in the weapon (Such as OnPlayerAttack()) when appropriate.
