Uncaught TypeError: d.setTo is not a function

[TheCodeCrafter]

Alright. I'll cut to the chase. I'm making a simple game about abducting people, and I want the victims to run from the player or "flying saucer". This is what I have setup in the update function (I'm pretty sure the rest is irrelevant, but tell me if you need more):

this.win.angle = game.physics.arcade.angleToXY(this.win, -(this.player.x), -(this.player.y));
		

this.win.velocity = game.physics.arcade.velocityFromAngle(this.win.angle, 145,       this.win.body.velocity);
		
game.world.wrap(this.win, 0, false);

 

 

 

Now here is the error after getting to the "play" state (Oh and by the way, the game is based off of the state tutorial for phaser, except with a lot of edits and a lose.js file.):

Uncaught TypeError: d.setTo is not a function

Please help!
