Hi Guys,
I have an issue where game maker can't draw circles when I'm running a shader. it is a simple colour shader.
VSH shader code
FSH shader code
without the shader running, the circles are drawn perfectly fine, but when I add the shader the circles are not drawn. Also, I changed the circle to a rectangle and the rectangle was drawn. is this normal?
please help.
I have an issue where game maker can't draw circles when I'm running a shader. it is a simple colour shader.
VSH shader code
Code:
//
// Simple passthrough vertex shader
//
attribute vec3 in_Position; // (x,y,z)
//attribute vec3 in_Normal; // (x,y,z) unused in this shader.
attribute vec4 in_Colour; // (r,g,b,a)
attribute vec2 in_TextureCoord; // (u,v)
varying vec2 v_vTexcoord;
varying vec4 v_vColour;
void main()
{
vec4 object_space_pos = vec4( in_Position.x, in_Position.y, in_Position.z, 1.0);
gl_Position = gm_Matrices[MATRIX_WORLD_VIEW_PROJECTION] * object_space_pos;
v_vColour = in_Colour;
v_vTexcoord = in_TextureCoord;
}
Code:
varying vec2 v_vTexcoord;
varying vec4 v_vColour;
uniform vec3 newColour;
void main()
{
vec4 colour = texture2D( gm_BaseTexture, v_vTexcoord );
colour.rgb *= newColour;
gl_FragColor = v_vColour * colour;
}
please help.
