What is wrong with my zipline script?
Hi, I am making a zipline thing, and I'm almost done, but there's one error that I get when I walk over a trigger, it says "NullReferenceException: Object reference not set to an instance of an object Zipline.OnTriggerEnter (UnityEngine.Collider Other) (at Assets/Zipline.js:15)" What is wrong here?
Here's my script:
var EndPoint : Transform;
public var IsRiding = false;
var PlayerPhysic : CharacterMotor;
var Player : GameObject;
var Speed : float;
function OnTriggerEnter(Other : Collider){
if(Other.gameObject.tag == "Player"){
Player.position = Vector3.MoveTowards(Player.position, EndPoint.position, Speed * Time.detlaTime);
IsRiding = true;
}
}
function Update () {
if(IsRiding == true){
PlayerPhysic.enabled = false;
}
if(IsRiding == false){
PlayerPhysic.enabled = true;
}
}
It looks like your Player or EndPoint variable is not assigned, so it is null. Trying to access any member of such null variable results in NullReferenceException...
No, you see, I have assigned them properly, I think there is something else that is wrong. It mentions line #15 when I get the error, so I'm guessing I have done something wrong with my script.
Please add this just before line 15, i.e. Player.position = Vector3.$$anonymous$$oveTowards(...)
print(Player);
print(EndPoint);
and see what is printed to the console.
It prints
Player (UnityEngine.Transform) UnityEngine.$$anonymous$$onoBehaviour:print(Object)
EndPoint (UnityEngine.Transform) UnityEngine.$$anonymous$$onoBehaviour:print(Object)
But I've managed to make it move, but the thing is that it moves in just one millisecond, it doesn't have a smooth effect between the positions:
function OnTriggerEnter(Other : Collider){
if(Other.gameObject.tag == "Player"){
print(Player);
print(EndPoint);
Player.transform.position = Vector3.Lerp(Player.transform.position, EndPoint.transform.position, 3 * Time.deltaTime);
IsRiding = true;
}
}
If it prints correct values, then you probably made some fix ;)
Regarding movement - you can use lerping in coroutine to achieve smooth effect. For example please see this answer.
