|index||The index of the tile to check.|
This function is used to get the top (y axis) local position
within the background image asset of the specified tile. It
is important to realise that the value returned is in relation to
the background image used to create the tile, where the top left
corner is the (0,0) position, and is not the position of the
resource within the room.
var tile, ww, hh, ll, tt;
tile = tile_layer_find(-1000, mouse_x, mouse_y);
ww = tile_get_width(tile);
hh = tile_get_height(tile);
ll = tile_get_left(tile);
tt = tile_get_top(tile);
tile_add(bck_Tileset, ll, tt, ww, hh, posx, posy, -1000);
The above code will first get the index of a tile at the mouse position with a depth of -1000 and then use that value to store various attributes in local variables. These attributes are then used to add a new tile into the room.
