I have directions stored in the command_array  and simply want the sprite (this.player) to move to the right. I am using the function moveToXY() like this: for (var i = 0; i < this.command_array.length; i++) { if (this.command_array[i].key === 'walk_right_com') { this.game.physics.arcade.moveToXY( this.player, //sprite reference this.player.body.x + 150, // target x position
