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.
|handle||The handle of the shader constant to set.|
|array||A previously initialised array of floating point values.|
shader_params = shader_get_uniform(shader_tint, "cMatrixArray");
The above code will get the handle of the shader constant "cMatrixArray" then set that constant to the given array.
