shader_set_uniform_i(handle, value1 [, value2, value3, value4]);
Argument | Description |
---|---|
handle | The handle of the shader constant to set. |
value1 ... value4 | The integer value (or values) to set the shader constant to. |
Returns: N/A
With this function you can set the value (or values) of a shader
constant. You must previously have gotten the "handle" of the
constant using the function shader_get_uniform, and you
will have to know what type of constant it is to pass the correct
number of integer values through to it, ie: if you have a
vec2 you will need to pass two values to the function.
NOTE: All uniforms must be set after calling the
function shader_set(), and
before calling shader_reset.
shader_set(shader_Glass);
shader_params = shader_get_uniform(shader_glass, "u_vParams");
shader_set_uniform_i(shader_params, 0, 65, 255);
draw_self();
shader_reset();
The above code will get the handle of the shader constant "u_vParams" ( a vec3), then set that constant to the given integer values.
