Mecanim Combo Tree returning to Idle State

Question

I've been bashing my head over this and trying to find similar answers in the forums but no luck so far. Basically I want to set up a super simple combo system for a player:

{1,} {1, 2,} {1, 2, 3,} {1, 4,} {5,}

Better visualised here: alt text

It transitions between states well, it's just getting it to go back to idle after either a partial or full combo. I've tried setting up a Queue system that basically houses an enum for the state of each of these animation states, and if that queue is ever empty to return to state 0 (idle) however that now stops be going beyond the combo of just 1st (Swing/Throw) so I'm unable to do anything more than 1 attack.

Code as follows: using UnityEngine; using System.Collections; using System.Collections.Generic;

 public class AnimationScript : MonoBehaviour {
 
     //Setup private Animation component for the player
     private Animator playerAnim;
     //Setup parameter variable for AnimationTree
     private int MousePressVal;
     //Setup private enum to help transition Animation states
     enum PlayerAnimationState
     {
         idle,
         firstswing,
         secondswing,
         slam,
         firstthrow,
         secondthrow,
     };
     //Private enum Variable
     PlayerAnimationState pas;
     //Set up queue for linking back to Idle
     private Queue<int> attackQueue = new Queue<int>();
 
     // Use this for initialization
     void Start () {
         //Set private Animation component to the Animation component attached to this item
         playerAnim = GetComponent<Animator>();
         pas = PlayerAnimationState.idle;
     }
     
     // Update is called once per frame
     void Update () {
         if(Input.GetMouseButtonUp(0))
         {
             //Left Mouse Press
             MousePressVal = 0;
             PlayAnimationTree(MousePressVal);
         }else if (Input.GetMouseButtonUp(1))
         {
             //Right Mouse Press
             MousePressVal = 1;
             PlayAnimationTree(MousePressVal);
         }
     }
 
     void FixedUpdate()
     {
         if(attackQueue.Count > 0)
         {
             playerAnim.SetInteger("EnumPAS", attackQueue.Peek());
             attackQueue.Dequeue();
         }else
         {
             pas = PlayerAnimationState.idle;
             playerAnim.SetInteger("EnumPAS", (int)pas); 
         }
     }
 
     void PlayAnimationTree(int MouseAttackVal)
     {
         switch(MouseAttackVal)
         {
             case 0:
                 if(pas == PlayerAnimationState.idle)
                 {
                     Debug.Log("1st Swing Queued");
                     pas = PlayerAnimationState.firstswing;
                 }else if(pas == PlayerAnimationState.firstswing)
                 {
                     Debug.Log("2nd Swing Queued");
                     pas = PlayerAnimationState.secondswing;
                 }else if(pas == PlayerAnimationState.secondswing)
                 {
                     Debug.Log("Slam Queued");
                     pas = PlayerAnimationState.slam;
                 }
                 break;
             case 1:
                 if(pas == PlayerAnimationState.idle)
                 {
                     Debug.Log("1st Throw Queued");
                     pas = PlayerAnimationState.firstthrow;
                 }else if(pas == PlayerAnimationState.firstswing)
                 {
                     Debug.Log("2nd Throw Queued");
                     pas = PlayerAnimationState.secondthrow;
                 }
                 break;
         }
         attackQueue.Enqueue((int)pas);
         //playerAnim.SetInteger("EnumPAS", (int)pas); 
     }
 }

So my question is now: How the hell do I allow for a lag time which allows for a 2nd and possible 3rd attack swing for the player as it just snaps back to Idle right now.

Cheers

You need to hold on to what's in the queue for longer. You have dequeue in FixedUpdate so you're queue will never get large enough to hold a combo. I recommend you have some sort of timer to remember how long ago the combo started.

 private float lastAttackTime = 0;
 private float comboTimeWindow= 0.5;
 void Update() {
   if(...) {
     lastAttackTime = Time.time;
   }
   if (Time.time > lastAttackTime + comboTimeWindow) {
     dequeue();
   }
 }
