ParticleSystem.RotationOverLifetimeModule.zMultiplier

Description

Rotation multiplier around the Z axis.

This method is more efficient than accessing the whole curve, if you only want to change the overall rotation multiplier.

		AnimationCurve curve = new AnimationCurve();
		curve.AddKey(0.0f, 0.0f);
		curve.AddKey(1.0f, 1.0f);

		rotationOverLifetime.zMultiplier = (Mathf.PI * 2.0f);

		var psr = GetComponent<ParticleSystemRenderer>();
		psr.material = new Material(Shader.Find("Sprites/Default"));	// this material renders a square billboard, so we can see the rotation

		hSliderValue = GUI.HorizontalSlider(new Rect(25, 45, 100, 30), hSliderValue, 1.0f, 5.0f);
