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.
ds_grid_value_exists(index, x1, y1, x2, y2, val);
|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.|
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.
