pulling objects
i was wondering how to make a collider that pulls an object in a direction so usually i can make the collider pull the object to the center of it. but i just want it so if an object enters the collider it will move all the way through it and only stop once it has exited the collider
Hey there,
try the following:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class PullScript : MonoBehaviour {
private List<GameObject> pullObjects;
public Vector3 pullDirection;
public float pullSpeed;
void Start () {
pullObjects = new List<GameObject> ();
}
void Update () {
foreach (GameObject obj in pullObjects) {
obj.transform.Translate (Time.deltaTime * pullSpeed * pullDirection);
}
}
public void OnTriggerEnter(Collider col)
{
Debug.Log ("object entered");
pullObjects.Add (col.gameObject);
}
public void OnTriggerExit(Collider col)
{
pullObjects.Remove (col.gameObject);
}
}
Attach this script to an object that should pull others through. You can define a speed and a pullDirection in the editor. Both objects need a trigger Collider! One of them additionaly needs to have a rigidbody attached. Otherwise unity will not register any collision.
ok so im not sure how to work the settings because rightnow its not doing anything.
ok so i figgured it out and it works but the problem is if i have it set to pull objects through it along the z axis it pulls the object depending on how the object is facing so the objects end up going in random dirrections depending on what their z axis is
so how can i make it push all objects in the same dirrection rather than from the way they are facing
$$anonymous$$y bad, apparently i did think this through completly. Currently the translate function translates along a vector relative to the transform of the object to translate.
The thing you need is to change line 16 into:
obj.transform.Translate (Time.deltaTime * pullSpeed * pullDirection,Space.World);
or:
obj.transform.Translate (Time.deltaTime * pullSpeed * pullDirection,transform);
The first option will interpret the translate vector in world-space. The second option will interpret it relatively to the transform of the pulling object.
thanks! tryingit out soon i will let you know how it goes!
how can i make it so that it can only effect objects with the tag of "Untagged"?
just add an if statement in the OnTriggerEnter function:
if (col.tag == "Untagged") {
pullObjects.Add (col.gameObject);
}
Thanks man, one more question, how can I make it so that no matter where an object enters the collider it will just be pulled straight through, not following an x y org axis just wherever it enters the collider it will be pulled to the opposite side from where it entered?
