As you can see, the rectangle defined by (50, 90) to (200, 180) marks all the equivalent MP grid cells that it touches as being forbidden.This function asks you to define a rectangle within the room, and then it marks all MP grid cells "touch" that rectangle as being forbidden, meaning that the path-finding functions cannot cross them. The image below illustrates how this works:
As you can see, the rectangle defined by (50, 90) to (200, 180) marks all the equivalent MP grid cells that it touches as being forbidden.
mp_grid_add_rectangle(id, x1, y1, x2, y2);
| Argument | Type | Description |
|---|---|---|
| id | MP Grid ID | Index of the mp_grid that is to be used |
| x1 | Real | The x coordinate of the left side of the rectangle to check. |
| y1 | Real | The y coordinate of the top side of the rectangle to check. |
| x2 | Real | The x coordinate of the right side of the rectangle to check. |
| y2 | Real | The x coordinate of the bottom side of the rectangle to check. |
N/A
mp_grid_add_rectangle(grid, 0, 0, 100, 200);
The above code will mark as forbidden all cells of the mp_grid indexed in the variable "grid" that fall within the area 0,0 to 100,200.
