shader_set_uniform_matrix_array

With this function you can set a shader constant to hold an array of matrix values. You must previously have gotten the "handle" of the constant using the function shader_get_uniform(), and you will have to have previously initialised the array as an array of floating point values, where each successive group of 16 floats is a 4x4 matrix.

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

 

Syntax:

shader_set_uniform_matrix_array(handle, array);

ArgumentTypeDescription
handleShader Uniform HandleThe handle of the shader constant to set.
arrayArrayA previously initialised array of floating point values.

 

Returns:

N/A

 

Example:

shader_set(shader_Glass);
shader_params = shader_get_uniform(shader_tint, "cMatrixArray");
shader_set_uniform_matrix_array(shader_params, matrix_array);
draw_self();
shader_reset();

The above code will get the handle of the shader constant "cMatrixArray" then set that constant to the given array.
