is Hitting Tile

Check if a sprite is currently hitting a wall.

sprites.create(null).isHittingTile(CollisionDirection.Right)

A wall is either a tile set as a wall or the edge of the scene if a tilemap is set.

Parameters

• direction: the direction the sprite moves toward when detecting a wall collision: left, right, top, or bottom.

Returns

• a boolean value that is true if the sprite is hitting a wall on the chosen side or false if not.

Example

Make a tilemap with a wall going from top to bottom. Set a sprite in motion and make it say “Ouch!” when it hits the wall on its right side.

tiles.setTilemap(tilemap`level1`)
let mySprite = sprites.create(img`
