ds_grid_value_disk_exists(index, xm, ym, r, val);
| 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. |
| val | The value to find. |
Returns: Boolean
With this function you can check to see if a specific value
(real or string) is present within a circular area of a given
ds_grid. If it is present the function will return true
otherwise it will return false.
if ds_grid_value_disk_exists(grid, 5, 5, 5,
val)
{
xpos = ds_grid_value_disk_x(grid, 5, 5, 5,
val);
ypos = ds_grid_value_disk_y(grid, 5, 5, 5,
val);
}
The above code checks a ds_grid for a specific value within a disk region. if it is found, it then stores the x and y position of the value in two variables for later use.
