Title: Shaders on Android
Post by: r_y_n_o on March 25, 2016, 09:28:08 pm

I'm making a game, and I'm using shaders.
Today I tried to compile for android and everything crashed.
After a lot of debugging with the logcat, I noticed that shaders were failing to be loaded.
So I went to the source code of SFML and notice that when SFML_OPENGL_ES is defined, all the shaders functions just return false, and nothing else.

Why is that? I mean, shaders are supported since 2.0, shouldn't it be supported by sfml? Online I've seen examples of people using shaders on android with sfml, so I guess there is a way....

SFML uses OpenGL ES 1.1 on Android, which doesn't support shaders. So no there's no way, and you can't have seen SFML apps using shaders on Android ;)

You should at least document it...

I spent a day trying to figure out the problem, it is not mentioned anywhere in the docs... I mean, it's probably the most relevant information you should give...

Also I had to figure out by myselft that QUADS are not supported by looking at the source code

Yeah, sorry for the lack of support. Mobile ports are still experimental (or even unmaintained, for iOS), so they have no official documentation yet.
