Argument Description handle The handle of the shader constant to set.
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.IMPORTANT! This function is not available with the Trial Licence of the product.
shader_matrix = shader_get_uniform(shader_glass, "u_vMatrix");
The above code will get the handle of the shader constant "u_vMatrix" then set that constant to the current transform matrix.
