• Hi everyone! I'm currently working on a series of books about 2D Shader Development.

The idea is to synthesize a bunch of techniques that are specifically useful for 2D, even if they work on 3D as well.

I released the first book last week. It's 4.99 on Amazon or free on the series website, https://www.2dshaders.com

This is an independent initiative, I don't work for any publisher whatsoever. The contents of the books are the result of a 4-year span where I started teaching this in Argentina and USA, always making the workshop better. Now I'm expanding it to make more sense in book form.

I'd love to hear your opinions on the idea and if you get the book let me know what you think.

By the way, the examples are in Unity, but the concepts from the book should be easily transferable to any graphics api/engine.

Hope you like it!

• While looking out for that pesky Terrator, our little alien is doing a bit of relaxed mining down on the new gas planet "Lelantos" this weekend....

• I have a native iOS game (objective c, XCode build) which I am considering to port to other platforms.
Core gameplay is based on solely on geographical maps, and custom drawing over maps. It also has Core Data. This part is complete in development.
What is not done yet is: monetization, gamification (leaderboards, challenges) and multiplayer functionality.
As I think more about it, I am tempted to think if this is the right time to move to a cross platform tool such as Unity. But before dedicating time to port my 5 years side-project effort in Objective C, I really want to know if its worth it.
- Does Unity support such plugins / assets that will fulfill all my above requirements?
- Unity Personal seems to have only 20 concurrent users - is it too costly scaling if I decide for extending to web and android platforms?
- What is the general workflow involved in publishing to iOS, Android, PC, and web platforms while using Unity? I mean to ask about various points of signing stuff, paying fees and getting certified.
- How long will it really take to port my entire Objective C project into Unity? I am somewhat familiar with C# but I am finding it hard fidgeting with Unity IDE as lot of things are focused around FPS and 3D while my game is still 2d - not much action involved. I seem bit overwhelmed by the list of features I see there. All in all, I do not want to lose my momentum while still making sure its portable to everywhere.
- Any assets I could use (for free to try basis in debug) that are relevant for my game?
- Last but not the least, are there any costs that I need to be paying upfront to Unity, for using it (apart from their monthly subscription model)? I don't understand their costing for multiplayer in conjunction with their subscription fees - if someone could kindly elaborate.

Hello,
me and few friends are developing simple city building game with unity for a school project, think something like Banished but much simpler. I was tasked to create the path-finding for the game so I mostly followed this tutorial series up to episode 5. Then we created simple working system for cutting trees. The problem is that the path-finding is working like 90% of the time, then it get stuck randomly then there's clearly a way to the objective (tree). I tried looking for some pattern when it happens but can't find anything. So basically I need any tips for how I should approach this problem.
Use this image to visualize the problem.

i just excanged my old IDE (C++Builder) to the free MS Visual C++ 2005 ExpressEdition (full img-download) and tried to figure out, how to work with it. now i got 2 problems: its easy to generate a WinApp. forms, buttons ect. but when i enter a source snipped (i.e. code to be executed when a button is pressed) the IDE tells me to put it into the "form.h". isn't code supposed to go into the "form.cpp" or whatever? and the headers to be inside the header-file? second: how can i update the offline help? i know there is always the online-help and it is more up to date ect. but if my i-net gots down or i want to use the help on a non-connected PC? i get annoying errors to, when using the local-part of the help:

help is installed (the link providet isn't usefull either ^^) fulltext-search finds the file online but not locally and i already reset the help to full "local first, then online" and all the sources on the dumb thing is, the page i tried to open locally is accessible through the online-help if i manually locate it or via search function. but VS doesn't keep the files it downloaded. me thinks: no wonder i don't like MS products. it's mutual... can anybody help me?

You aren't required to put code in cpp files. Putting the code in the class declaration automatically inlines it in native C++, for example. In managed it seems that the automatic method creator wants you to put it in the class declaration as well.

You don't have to.

class Form1{  private: void MyControl_OnResize(Object^ obj, EventArgs^ e)  {    //TODO: Stuff  }};

just remove the body of the function, and create a Form1.cpp and do:
void Form1::MyControl_OnResize(Object^ obj, EventArgs^ e){  //TODO: Stuff}

Microsoft simply recommends you leave it in the prior form. Why? I guess it's less files.

I've never had any trouble with the help files, personally. You sure you don't have any filters or anything?

second: stupid MS for 'breaking' (or bending) (C++)standards... again

third: i first hat ZoneLabs lock out net-access for VS, and deactivated any online-ressources in the help-options. accidently i had "Local help" switched off for "search in providers" too. help worked until i stumbled across the missing help-page. (Help -> How do I -> Windows Applications -> Code for Windows Form Applications aka "the missing file")
then i released any locks and set the help-options back to "every thing on", but the pages remain only accessible through the msdn-page.
as of filters, the language filter is set to C++, since i don't need help on VBasic, C# or Java. haven't seen any other filters yet.

I'm fairly certain you're working in Managed C++, which already breaks with the standards by providing interface, sealed, abstract, ref, value, ^ as a handle, % to get handle, only supporting single inheritance except from interfaces, etc. It's my understanding that the method they want you to use is more like the other .net languages.

I recall (my dev computer is in the process of being restored from backups atm) there being filters on which libraries to search as well.

But it seems you're just missing a help file, or the link isn't right. I've never used "How Do I" so I don't know.

 second: stupid MS for 'breaking' (or bending) (C++)standards... again

It's not that they are 'breaking' the standard at all. If you are using Managed C++, that is more or less a new language built on top of C++ with added functionality. It isn't meant to be compliant to the C++ standard, its just meant to possibly shorten development times. If you want normal standard compliant C++ than you can use that with their compiler too, you just lose the added features introduced into the Managed C++ language. I don't think you can use straight C++ for Windows Forms coding though, I think you are stuck with Managed C++, or C# or another .NET language. If you aren't using Managed C++, then I'm not sure what you are refering to with MS 'breaking C++ standards.' If it is the fact that they seem to want yout to implement class member functions in the header instead of a seperate .cpp file, then that is perfectly legal by the C++ standard. You can always define a class along with all it's member functions in the header, providing you implement the members within the class definition. I know it is fashionable to always hate Microsoft, but in this case it isn't really a just criticism.

MS: "do it our way or dont do it at all"

the CBuilder had none of the fancy stuff like "managed" C++ and could build WindowForms quite well. guess it would be easier just to upgrade it with BCC5.5 and drop VS again.

it's not that i hate MS, i just don't like their attitude and the way we are (i am) forced to use their products. there is not always an alternative. *sigh* less complaining, more problem solving and programming ;)

You're using the express edition, the scaled down edition with the bare necessities. I can't speak to wether the standard has a form builder for native use, but it's not all that surprising that the express edition is limiting.

You can, they used to do it with MFC. They've since dropped MFC because it was... yeah. But you can still build forms with C++ using the platform sdk apis. It's just... difficult to make dialog boxes without a form builder. Making forms is easy enough, you just use CreateWindow for all the controls, but dialog boxes must be "predefined" (more or less), and the platform help for building dialog boxes is shoddy at best. Form builders make it a lot easier.

No, "do it our way or do it your own way." Regular C++ is still usable (in the same IDE). Don't immediately assume that your problems stem from MS being evil.
