Unity动画C＃代码

Question

I am making a game similar to doodle jump, 3d, I want when the player touches an obstacle the animation will play, that means that oncollisionenter the animation must play, I think it doesn't work because I don't click on any button so the animation will play, the player jumps automatically, so after it touches once the obstacle it continues looping and looping and it doesn't stop, please help me here is the code for left right movement , jump, and here I included animation:

using UnityEngine;
using System.Collections;

public class LeftRightMovement : MonoBehaviour {
    public float jump = 15f;
    float speed = 4f;
    float movevelocity;
    static Animator anim;
    void Start()
    {
        anim = GetComponent<Animator> ();
        anim.SetBool ("isJumping",false);
    }
    void FixedUpdate () 
    {
         if (Input.GetKey (KeyCode.LeftArrow) || Input.GetKey (KeyCode.A)) 
            {
                this.gameObject.transform.Translate (Vector3.left * Time.deltaTime * -speed);                                       
            } 
            else if (Input.GetKey (KeyCode.RightArrow) || Input.GetKey (KeyCode.D)) 
            {
                this.gameObject.transform.Translate (Vector3.right * Time.deltaTime * -speed);
            }

    }

    void OnCollisionEnter(Collision col)
    {
        if (col.gameObject.tag == "Obstacle") {
            GetComponent<Rigidbody> ().velocity = new Vector3 (GetComponent<Rigidbody> ().velocity.x, jump, 0);
                anim.SetBool ("isJumping",true);
        } else if (col.gameObject.tag == "Platform") {
            GetComponent<Rigidbody> ().velocity = new Vector3 (GetComponent<Rigidbody> ().velocity.x, jump, 0);
            anim.SetBool ("isJumping",true);
        } else if (col.gameObject.tag == "Monster") {
            GetComponent<Rigidbody> ().velocity = new Vector3 (GetComponent<Rigidbody> ().velocity.x, jump, 0);
            anim.SetBool ("isJumping",true);
        } else if (col.gameObject.tag == "Virtaliot") {
            GetComponent<Rigidbody> ().velocity = new Vector3 (GetComponent<Rigidbody> ().velocity.x, jump * 3, 0);
            anim.SetBool ("isJumping",true);
        } else if (col.gameObject.tag == null) {
            anim.SetBool ("isJumping",false);
        }
    }
}

please help me!

Answer 1

In your code you set isJumping to true when colliding with an obstacle but you never set it back to false so it never stops.

Also you should instantiate a rigidbody variable like that:

Rigidbody rigidbody = GetComponent<Rigidbody>();

So you can reuse it with using GetComponent each time you need it.

Hope that helps you.

Answer 2

In your animator state machine, click on the "Jump" state. Then click on the jump animation (upper right). In the inspector, you should see the parameters of your animation. Untick the "loop time" checkbox. This will make your anim play only once when you arrive in the Jump state.

Answer 3

You should make an oncollisionexit function where you will stop the animation:

Using UnityEngine;
using System.Collections;

public class Example : MonoBehaviour{

 void OnCollisionExit (Collision collisioninfo){

    GetComponent<Animation> ().Stop ("Jumping");

     }
}
