matrix_multiply(matrix1, matrix2)
| Argument | Description |
|---|---|
| matrix1 | The first matrix (as an array) to use. |
| matrix2 | The second matrix (as an array) to use. |
Returns: Array
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);
matrix_set(matrix_view, new_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.
