• 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.

# Unity Entry point and SDL

This topic is 4320 days old which is more than the 365 day threshold we allow for new replies. Please post a new topic.

Hello, I.m trying to setup a starting project that will use SDL, but it seems it wont work du to some SDL entry point re-mapping. So basically my source file is:
#include <SDL.h>

int main(int argc, char *argv[])
{
return 0;
}


the build log is:
------ Rebuild All started: Project: Motus, Configuration: Debug Win32 ------
Deleting intermediate and output files for project 'Motus', configuration 'Debug|Win32'
Compiling...
main.c
LINK : fatal error LNK1561: entry point must be defined
Motus - 1 error(s), 0 warning(s)

I'v already read this topic (will open on a new window) but it did not help. I'm not too newbie relative to visual c++ (express), so I guess I've set up the project almost rightly. - Include directories: I:\sdk\SDL\include - Lib Directories: I:\sdk\SDL\lib - Additionnal dependencies: SDLmain.lib SDL.lib - The project is set to compile as C code (/TC) - Debug build, all optimization stuff is disabled - I've tried to add extern "C" to my main but it did not work either (error: string, of course, as C code. And as Cpp code the entry point is still not found, but I need my project to be plain C anyway) I hope I included all relevant information, and that someone can help me. Regards, Janta

So, I eventually fixed this, after couple hours tweaking with VC++ options.
I'm far far away from being an expert, so this is what was probably happenning, I guess.

SDL turn your main() into an SDL_main(), so your main is not the actual entry point any more.
So you need to inform your compiler about the target subsystem so as it can determine the appropriate entry point. (I don't have a deep understanding about that...)

So what fixed my problem with VC++ Express is set the SubSystem to Windows in
Properties -> Linker -> System -> SubSystem.

Maybe it could help someone, someday.
