Trigger animation
Hi, I am new to unity programming .I have following issue
-We want enemy object to Play certain animation if it enter trigger of player .
-Player trigger is detected with debug.Log but the object animation is not .it keeps playing animation given in update.Thanks in advance
using UnityEngine;
using System.Collections;
public class test : MonoBehaviour {
// Update is called once per frame
void Update () {
GetComponent<Animation>().Play ("Turn");
}
public void OnTriggerEnter(Collider other)
{
if (other.gameObject.tag == "Player")
{
GetComponent<Animation>().Stop ("Turn");
Debug.Log("Trigger");
}
}
}
Update is called on every frame, so I think when you're calling the new animation, its just immediately being overwritten by the update.
It might be a quick and easy fix to add a bool, which returns true when the player hits the trigger, and goes back to false when the animation is finished. Then use an if statement in your update to check that the bool is true.
If you have a lot of animations though it might be worth making a State Machine, which can be used to switch animations but its more complicated.
Untested example:
private bool playTriggerAnimation; //create a boolean
void Update () {
if(!playTriggerAnimation) //if the boolean is false (the ! prefix is a shorthand way of saying "PlayTriggerAnimation == false"
GetComponent<Animation>().Play ("Turn");
}
public void OnTriggerEnter(Collider other)
{
if (other.gameObject.tag == "Player")
{
playTriggerAnimation = true;
GetComponent<Animation>().Stop ("Turn");
Debug.Log("Trigger");
GetComponent<Animation>().Play ("NewAnimationHere");
if(!GetComponent<Animation>().isPlaying("NewAnimationHere")) //if "NewAnimationHere" is not playing
playTriggerAnimation = false;
}
}
If you do want to create a state machine to handle multiple animations, theres a great tutorial for it here http://www.3dbuzz.com/training/view/3rd-person-character-system/integrating-maya-characters - starting at no.15 :)
Thanks Okido, It works fine but there is some error in that last if statement, is it must to return that bool back to false. -> if I remove last if it works.
But I got following error when i dont
-> unexpected symbol I think you missed a circular bracer
at last. But when I add it give following error
error CS1955: The member `UnityEngine.Animation.isPlaying' cannot be used as method or delegate
Ill try doing this using state machines but just want to check this error .Thanks in advance!
Sorry for the slow response, I was waiting until I could check one of my own projects for why that error might be happening. The API was updated with Unity 5 so things that used to work may not anymore.
You could try just using "GetComponent().isPlaying" (ins$$anonymous$$d of GetComponent().isPlaying("NewAnimationHere")) It seems to think the brackets are a method when using "isPlaying" for some reason.
I've had problems checking that animation properties were false, so I've done this ins$$anonymous$$d
if(GetComponent<Animation>().isPlaying)
return;
else
playTriggerAnimation = false;
Not sure why, but it tends to work for me. :p A state machine is the best way to go though, good decision! if your problem is solved you can click the little check mark the question as answered :)
Hi! if you are using collision this might be the good one!
animator anim;
bool hitplayer;
void Update(){
if(hitplayer){
anim.play("you animation for hitplayer like fight when hit the player"); } }
void OnTriggerEnter2D(Collider2D other){ hitPlayer = false; anim.Play ("fightAnim");
} }
void OnTriggerExit2D(Collider2D enemwalk){
hitPlayer = true;
} its works great with my game!. Hope this help :)
