mp_grid_draw(id);
| Argument | Description |
|---|---|
| id | Index of the mp_grid that is to be drawn |
Returns: Boolean.
This function will draw the specified mp_grid, marking free
cells as green and forbidden cells as red. This function is
essential as a debug tool but it should be noted that it is
very slow and only works when used in the draw event
of the instance.
draw_set_alpha(0.3);
mp_grid_draw(grid);
draw_set_alpha(1);
The above code will draw the mp_grid indexed in the variable "grid" as a semi-transparent overlay (but only if the instance running the code has a depth lower than all the rest).
