Endless Sky open source - Source code

[Faust]

Hi guys,

I've found the source code of the game Endless Sky, it's a 2D trading and space combat game. I know that there is already this kind of game on the Pandora, like The Battle For The Solar System - The Pandoran War.

Source code:

Unfortunately it's written that the game requires OpenGL 3.0, if someone wants to have a look, or tries to port it.

You can't port OpenGL 3 code to the Pandora, unless you have a wrapper that can help with that to GLES 2.0 code. Even glshim only takes care of fixed pipeline for now, so it's probably not feasible at this stage.

It's one of my many started project. But if some one wants to do it, it's not an issue for me.

Thanks Faust, had no idea that there was any Free Software (that's 'Free' as in : as per the terms of the GNU GPL version 3 or later.) on Steam. Good to see

I was a huge EV fan and just started playing this. I think it would be a perfect fit on the Pandy. Really great.

It looks like I can port it to GL|ES2 pretty trivially if that's useful to anyone...

I have no idea if that helps get it onto the pandora but if it did I'd love you forever.

Right, I made some progress on this:

https://github.com/JonnyH/endless-sky/tree/gles2

This builds on my desktop linux machine and runs using the GLES2 driver (plus "GL_EXT_texture_format_BGRA8888" and "GL_OES_vertex_array_object" extensions - both of which are supported by powervr, possibly depending on driver version though... Both aren't really necessary, but performance advantages).

It seems everything but the texture swizzle used to recolour ships (for different groups/cloaked), so it should be playable? I guess?

It'll likely need someone to check the input/SDL2 context creation works on the pandy though....

Happy to try out anything if its ready. Don't have much to offer on the back end or software side sadly. Let me know if I can be of any assistance.

It currently doesn't work on the pandora, as it tries to upload ~500 mb of textures to the gpu...

I'll have to look into either lower res stuff, or some kind of texture compression.
