shader_set_uniform_matrix

With this function you can set the value (or values) of a shader constant to the current transform matrix (as set using the Matrix Functions). You must previously have gotten the "handle" of the constant using the function shader_get_uniform().

NOTE All uniforms must be set after calling the function shader_set and before calling shader_reset.

 

Syntax:

shader_set_uniform_matrix(handle);

ArgumentTypeDescription
handleShader Uniform HandleThe handle of the shader constant to set.

 

Returns:

N/A

 

Example:

shader_set(shader_Glass);
shader_matrix = shader_get_uniform(shader_glass, "u_vMatrix");
shader_set_uniform_matrix(shader_matrix);
draw_self();
shader_reset();

The above code will get the handle of the shader constant "u_vMatrix" then set that constant to the current transform matrix.
