Hey. Me again. I'm trying to figure out why my randomly placed platforms for my platform game won't be immovable. I've included the physics and enableBody to the group.. this._platforms = game.add.group();this._platforms.enableBody = true;game.physics.enable(this._platforms, Phaser.Physics.ARCADE);this._platforms.body.immovable = true; The player lands on the platform and the platform goes down with the player, both top/bottom and left/right. I get this error: Uncaught TypeError: Cannot set property 'immovable' of undefined Thanks in advance!
