This action is used to get a tile index on a given layer. The layer is specified from the layer name given (a string, as used to name the layer in the Room Editor), and then you give an x and y position to find the tile to get the index of. The tile will be the one that the given position falls within in the room, and the index will be returned to the target variable. The x and y position can be flagged as being relative to the position of the calling instance, and the target variable can be flagged as a temporary (local) variable that can be used until the end of the event.
Argument Description Layer The layer to set the tile on x The x position to check y The y position to check Target The target variable to store the tile index
