|matrix1||The first matrix (as an array) to use.|
|matrix2||The second matrix (as an array) to use.|
With this function you can multiply two matrix arrays together
to create a new transform matrix. The function will return the new
matrix (again, as an array) which should be stored in a variable
for future use.
NOTE: You can't use a matrix constant as an argument with this function, so if you wish to multiply the (for example) view matrix with a custom matrix that you have built, you must first call matrix_get(type) and assign the view matrix values to an array variable, then multiply it by your custom matrix, and then set the chosen matrix (view, projection or world).
var v_matrix = matrix_get(matrix_view);
var new_matrix = matrix_multiply(v_matrix, my_matrix);
The above code will get the current view matrix, then multiply that with a custom matrix and then use the resulting matrix array to set the view matrix again.
