Trying to get trigger that opens door to work properly.

I have a feeling it's a problem in the animator, but we'll see.

Here is a video demonstrating the problem. The expected behavior is when the ball hits the cube it opens the door, and when it exits the door closes. Problem the first time the ball enters nothing happens, and on exit the door opens then closes (just watch the video).

I followed a tutorial made this script with some modifications to only allow the ball.

My code:

Code (csharp):

1.  
2. using UnityEngine;
3. using System.Collections;
4.  
5. public class SetAnimationBoolOnTrigger : MonoBehaviour {
6.  
7.     public string animationBoolName;
8.     public Animator target;
9.  
10.     void OnTriggerEnter(Collider coll)
11.     {
12.         if (coll.gameObject.tag == "Ball")
13.             Debug.Log("Ball Entered! Door Opening!");
14.             target.SetBool(animationBoolName, true);
15.     }
16.  
17.     void OnTriggerExit(Collider coll)
18.     {
19.         if (coll.gameObject.tag == "Ball")
20.             target.SetBool(animationBoolName, false);
21.     }
22. }
23.  

The videos shows the issue, and shows the animator set up. Mine deviates a bit from the one shown in the the tutorial I linked, because I had the opposite issue he had.

Anyway how do I fix this so when the ball hits the cube it opens the door, and when it exits the door closes? It's just weird to me that it doesn't work on the first entry.

 

Did you make sure that the initial value of animationBoolName is false?

 

Ya it is set to false.

 

You seem to be starting in the door open state. In the animation graph, "Initial" points to "DoorOpen", but the door is in fact not open. The graph and your visuals in the game don't match.

 

I swapped the initial to got to door close. Same thing happens. Doesn't work the first time, and upon the ball exiting the first time the door opens then closes. After that it works perfectly fine.

 

Check the state machine and the variable at runtime. Before you enter the cube, what is the state and what's the value of the boolean?

 

Not sure how to check that exactly, but the boolean should be false until the ball enters the cube.

 

Make sure you have the Animator window open at runtime that shows the controller that is responsible for the door.

 

I detached it, and nothing happens. Only thing that I can see is the transition from idle is white.

 

replace your code below,my english not good,so just try the code.

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class SetAnimationBoolOnTrigger : MonoBehaviour {
5.  
6.    public string animationBoolName;
7.    public Animator target;
8.  
9.    void OnTriggerEnter(Collider coll)
10.    {
11.        if (coll.gameObject.tag == "Ball")
12. {
13.       Debug.Log("Ball Entered! Door Opening!");
14.        target.SetBool(animationBoolName, true);
15. }
16.    }
17.  
18.    void OnTriggerExit(Collider coll)
19.    {
20.        if (coll.gameObject.tag == "Ball")
21.            target.SetBool(animationBoolName, false);
22.    }
23. }

 

Thank you so much! Those 2 brackets really made the difference!

 

you are welcome! ,it's my plesure
