Angle towards Velocity

[FlatBeatle 0]

Hi all,

I am having a little trouble trying to get my sprite to angle itself towards its current velocity. At the moment the zombies in my game are pointing to the top. They have a random velocity set in the code below. Is it possible to rotate these depending on the direction is it moving? 

Here is the code I am currently using. 

The enemies are spawning fine and moving in random directions, just trying to get the lads to rotate to their velocity is a pain.

createEnemies: function() {
		for (var x = 0; x < startingEnemies; x++) { // Create 5 enemies with random positions
			var enemy = enemies.create(this.game.rnd.integerInRange(50, 1870), this.game.rnd.integerInRange(50, this.game.world.height - 50), 'enemy');
			this.game.physics.enable(enemy, Phaser.Physics.ARCADE);
			enemy.body.velocity.setTo(this.game.rnd.integerInRange(50, 150), this.game.rnd.integerInRange(50, 150));
			enemy.body.bounce.set(1);

			enemy.body.collideWorldBounds = true;
			var animationZombie = enemy.animations.add('animationZombie');
			enemy.animations.play('animationZombie', 30, true);

		}
		enemies.x = 100;
		enemies.y = 50;
	}

I am using Phaser v2.9.2 and the ARCADE physics.

This is my first game and post, so let me know if there is any other information you require. 

Cheers!

atan2 should give you the angle in radians, so you could do:

enemy.rotation = Math.atan2(enemy.body.velocity.y,enemy.body.velocity.x) //rotation is in radians

If there's been at least one update, you can use

enemy.rotation = enemy.body.angle;

In the latest Phaser CE you can use

enemy.rotation = enemy.body.velocity.atan();
