Can you mirror a bunch of gameobjects ?
Hi all
I suddenly would like the ability to mirror a bunch of gameobjects, in my case with colliders attached.
any ideas?
In reality it is because I made some colliders manually for a rounded pair of stairs, and just want to copy those colliders to the other side. I tried scaling the colliders in a negative direction, but didn't work, so I guess I just have to do it manually again :)
sigh it's really confusing when people post questions, and it turns out the question is utterly and totally unrelated to what it sounds like the question is about
I guess sometimes it is just hard to put the questions right.. my bad, edited the question
Hi Jake :)
It's possible to just set all the scale values to -1 and then rotate your gameobject in the desired axis by 180 degrees.
Thanks $$anonymous$$mulla... that one worked! I guess I just didn't see it from the beginning
Wow. Thank you. I have been using Unity a long time now and I NEVER ONCE even thought of that. Crazy how obvious it seems now.
Wow - this is an amazing solution and saved me from a huge headache! Thanks, $$anonymous$$mulla!
Thank you! This solved a problem that would've had me stumped for hours, if not days!
It has a huge advantage over simply flipping the desired axis, that it does not mess up future transform operations done by the mirrored object!
Here's one way to mirror objects without adjusting the scale. You can use the public method to switch the master objects that you wish to manipulate.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class MirrorGameObjects : MonoBehaviour
{
public List <Transform> objsToMirror = new List<Transform>();
public Transform slaveParent;
private Transform[] masterObjs;
private Transform[] slaveObjs;
// Use this for initialization
void Start ()
{
CreateSlaves();
}
// Update is called once per frame
void FixedUpdate ()
{
MirrorObjects();
}
void CreateSlaves()
{
if (!slaveParent)
slaveParent = transform;
if (objsToMirror.Count < 1)
{
foreach (Transform child in transform)
{
objsToMirror.Add(child);
}
}
masterObjs = objsToMirror.ToArray();
slaveObjs = new Transform[masterObjs.Length];
for (int i = 0; i < objsToMirror.Count; i++)
{
slaveObjs[i] = Instantiate(masterObjs[i]);
slaveObjs[i].SetParent(slaveParent);
}
}
void MirrorObjects()
{
for (int i = 0; i < objsToMirror.Count; i++)
{
slaveObjs[i].localPosition = new Vector3(-masterObjs[i].localPosition.x, masterObjs[i].localPosition.y, masterObjs[i].localPosition.z);
slaveObjs[i].localEulerAngles = new Vector3(masterObjs[i].localEulerAngles.x, -masterObjs[i].localEulerAngles.y, -masterObjs[i].localEulerAngles.z);
}
}
public void SwitchMaster()
{
Transform[] temp = masterObjs;
masterObjs = slaveObjs;
slaveObjs = temp;
}
}
