|index||The index of the grid.|
|xm||The x position of the disk on the grid.|
|ym||The y position of the disk on the grid.|
|r||The radius of the disk on the grid.|
|val||The value to multiply the cells within the disk with.|
This function will take all the values in a given disc-shaped
region of the ds_grid, and multiply each one by the given
NOTE: This function will only work with real numbers, not strings.
ds_grid_multiply_disk(mygrid, 5, 5, 5, 2);
The above code will take all the values found within the circular grid area and multiply each one by 2.
