ds_grid_value_disk_x(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: Real
With this function you can get the x coordinate (within the
given grid disc-shaped region) of the value being searched for. Be
aware that if the value being searched for does not exists, the
function will return 0, so it is a good idea to check if the values
exists first with ds_grid_value_disk_exists
then run this function (along with the ds_grid_value_disk_y
function) to get the exact position within disc being searched.
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.
