Blend Tree: Forcing animations to the end

Questions & Answers
1

TL;DR: Image and script should be pretty much self-explanatory.

I’m working on a 2D game and I’m using Blend trees to determine which direction to look to (and animation to play) via mouse/player position.

When attacking, if fast enough, the animation changes midway (attacking left and if I move the mouse up the it changes to attack up midway). Is there a way to make sure the animation plays out until the end (ignore mouse movements for the duration of the animation)?

Relevant script:

public class PlayerController : MonoBehaviour {

  
	private Animator anim;

	void Start () {
	
		anim = GetComponent<Animator>();
	}
	

	void Update () {


	//Attacking

		if (Input.GetButtonDown("Fire1")) {
			anim.SetTrigger("Attack");
		}

		// Looking Direction


		//Finding out the angle

		Vector3 player = Camera.main.WorldToScreenPoint(gameObject.transform.position);
		Vector2 playerPos = new Vector2 (player.x, player.y);
		Vector2 mousePos = new Vector2 (Input.mousePosition.x, Input.mousePosition.y);

		Vector2 v = mousePos - playerPos;
		var angleRadians = Mathf.Atan2(v.y, v.x);
		var angleDegrees = angleRadians * Mathf.Rad2Deg;

		if (angleDegrees < 0) {
			angleDegrees += 360;
		}

		//Setting the direction

		if (angleDegrees > 315) {
			anim.SetFloat ("LookDir", 3);
		} else if (angleDegrees < 45) {
			anim.SetFloat ("LookDir", 3);
		} else if (angleDegrees > 225) {
			anim.SetFloat ("LookDir", 0);
		} else if (angleDegrees > 135) {
			anim.SetFloat ("LookDir", 1);
		} else if (angleDegrees > 45) {
			anim.SetFloat ("LookDir", 2);
		}
	}
}

Thanks! :smiley:

The easiest way would probably be to switch from using a blend tree to using individual animation states. With animation states, it’s just a matter of not having any transitions that trigger not on the end of the animation.
