This function can be used to check whether in a given set of tiledata the tile has been rotated 90 degrees or not. You give the tiledata, which can be retrieved using the function tilemap_get, and the function will return true if the tile is rotated, or false if not.



Argument Description
tiledata the tiledata to check




var lay_id = layer_get_id("Tiles_sky");
var map_id = layer_tilemap_get_id(lay_id);
var mx = tilemap_get_cell_x_at_pixel(map_id, mouse_x, mouse_y);
var my = tilemap_get_cell_y_at_pixel(map_id, mouse_x, mouse_y);
var data = tilemap_get(map_id, mx, my);
var bool = !tile_get_rotate(data);
data = tile_set_rotate(data, bool);
tilemap_set(map_id, data, mx, my);

The above code gets the tilemap ID from the given layer and then gets the x and y cell position for the tile under the mouse. This position is then used to get the tiledata which is rotated and then used to set the tile again.
