Same color on all child GameObjects instead of different colors with function
I'm making a scene in VR and I'm having a problem with a GameObject and its children.
So I have a ladder made from 13 parts, and I'm using VRTK to make it grabbable, and I have this function being called whenever I'm holding the ladder and also pressing the trigger button on the rift controller:
namespace VRTK.Examples
{
using UnityEngine;
public class Color2 : VRTK_InteractableObject
{
Color[] colors = new Color[6];
void Start()
{
colors[0] = Color.cyan;
colors[1] = Color.red;
colors[2] = Color.green;
colors[3] = new Color(255, 165, 0);
colors[4] = Color.yellow;
colors[5] = Color.magenta;
}
public override void StartUsing(VRTK_InteractUse usingObject)
{
base.StartUsing(usingObject);
LadderUse();
}
private void LadderUse()
{
GameObject[] objects = GameObject.FindGameObjectsWithTag("Ladder");
foreach (GameObject go in objects)
{
MeshRenderer[] renderers = go.GetComponentsInChildren<MeshRenderer>();
foreach (MeshRenderer r in renderers)
{
foreach (Material m in r.materials)
{
if (m.HasProperty("_Color"))
m.color = colors[Random.Range(0, colors.Length)]; ;
}
}
}
}
}
}
And my problem is that every part of the ladder gets a different color, what should I change to make them all get the same color instead? I'm pretty new to c#, unity and VRTK but everything is working like planned except this annoying part! I really appreciate if someone could help me out :)
One solution I can think of is to make all of the ladder child objects into one object instead, but I also don't know how to do that and I have ofc tried googling but I don't even know what to google in the first place
You've put random inside a loop. Move it out to get one random index and reuse it for all iterations.
private void LadderUse()
{
GameObject[] objects = GameObject.FindGameObjectsWithTag("Ladder");
int randomColorIndex = Random.Range(0, colors.Length);
foreach (GameObject go in objects)
{
MeshRenderer[] renderers = go.GetComponentsInChildren<MeshRenderer>();
foreach (MeshRenderer r in renderers)
{
foreach (Material m in r.materials)
{
if (m.HasProperty("_Color"))
m.color = colors[randomColorIndex];
}
}
}
}
