This function can be used to find the mean value for all the cells found within the defined disk area of a grid (all cell values are added together and then divided by the total number of cells that make up the disk), as shown in the image below:


ds_grid_get_disk_mean(index, xm, ym, r);

Argument Description
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.


Real or String


val = ds_grid_get_disk_mean(grid, 5, 5, 2)

The above code will set the variable "val" to the mean value contained within the given disk of the ds_grid indexed in the variable "grid".
