ds_grid_value_exists(index, x1, y1, x2, y2, val);
| Argument | Description |
|---|---|
| index | The index of the grid. |
| x1 | The x position of the left of the region in the grid. |
| y1 | The y position of the top of the region in the grid. |
| x2 | The x position of the right of the region in the grid. |
| y2 | The y position of the bottom of the region in 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 rectangular area of a given
ds_grid. If it is present the function will return true
otherwise it will return false.
if ds_grid_value_exists(grid, 0, 1, 5, 6, val)
{
xpos = ds_grid_value_x(grid, 0, 1, 5, 6,
val);
ypos = ds_grid_value_y(grid, 0, 1, 5, 6,
val);
}
The above code checks a ds_grid for a specific value within a rectangular region. if it is found, it then stores the x and y position of the value in two variables for later use.
