tile_set_rotate

Description

This function can be used to set a given set of tiledata to rotate the tile 90 degrees or not. You give the tiledata, 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 tiledata set which can then be applied using the tilemap_set function.


Syntax:

tile_set_rotate(tiledata, rotate)


Arguments:

Argument Description
tiledata the tiledata to set
rotate Set to true to rotate and false to leave it as-is


Returns:

Real


Example:

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.
