sf::Shape + sf::Shader = Nothing ?

[Haikarainen]

So I noticed you can't draw shapes using shaders, or they just wont draw. Why is this? This is a huge drawback for me, aesthetically speaking.

If I missed something; I try to render them on a RenderTexture (since I also have fullscreen shaders), wich I then draw on the RenderWindow. This works perfectly using Textures and Sprites, but not Shapes unless I decide to draw those perticular Shapes without shaders.

Also I'm drawing Circles and Lines

It should work, as long as you remember that shapes have no texture.

Can you show the shader that you use?

[Haikarainen]

Well that's kinda obvious heh, I should've known since i use gl_TexCoord and such. Full shader is below. I guess it would be possible to cache the shapes into textures by rendering them on a rendertexture?

That'll just leaves the problem with the lines. (I'm actually drawing a path with pathnodes represented as circles, and lines between them)

Code: [Select]

uniform sampler2D screen;
uniform float time;

uniform float divider;


void main(){
   vec2 offset = vec2(cos(time/500+gl_TexCoord[0].x*10)/divider, sin(time/500+gl_TexCoord[0].y*10)/divider);
   gl_FragColor = vec4(texture2D(screen, gl_TexCoord[0].xy+offset));
}
