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.
ds_grid_value_disk_exists(index, xm, ym, r, val);
| Argument | Type | Description |
|---|---|---|
| index | DS Grid | The index of the grid. |
| xm | Real | The x position of the disk on the grid. |
| ym | Real | The y position of the disk on the grid. |
| r | Real | The radius of the disk on the grid. |
| val | Any | The value to find. |
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.
