This function can be used to set a given set of tile-data to rotate the tile 90 degrees or not. You give the tile-data, which can be retrieved using the function tilemap_get(), and then set the rotate argument to either true if you want the tile rotated, or false if you want the tile to be in its default, un-rotated state. The function will return a modified tile-data set which can then be applied using the tilemap_set() function.
tile_set_rotate(tiledata, rotate)
| Argument | Type | Description |
|---|---|---|
| tiledata | Tile Data | The tile-data to set |
| rotate | Boolean | Set to true to rotate and false to leave it as-is |
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 tile map 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 tile-data which is rotated and then used to set the tile again.
