Access components in ALL children

Question

Hi. How do I access components in all of the children? When I used GetComponentInChildren it only changed it in one of the children, but I want all 9 to be changed.

Cheers.

 This wasn't tested, just an idea of iterating over comps in transform(gameObject.transform).  Anyways you should be able to get the general idea i hope.


 
 //unity script/javascript
 
 for (var child : Transform in transform) {
     for (var comp : Component in child.GetComponentsInChildren(Script)) {
          comp.name = "blah";
     }
 }
 
 // c#
 
 foreach(Transform child in transform)
 {
   foreach(Component comp in child.GetComponentsInChildren<SomeScript>())
   {
     comp.tag = "blah";
   }
 }

So I have to use GetcomponentsInChildren?

So for example if I wanted to set a boolean "blah" = true in "blahScript" in all children, how would I do it?

Is it something like this? :

for (var child : Transform in transform) { for (var comp : Component in child.GetComponentsInChildren(Script)) { comp.name = "blahScript"; } }

comp.blah = true;

Actually, you don't need the outer loop, and you'll need to put the assigment into the loop, of course:

 for (var comp : myScriptName in gameObject.GetComponentsInChildren(myScriptName)) {
     comp.blah = true;
 }

Note if the object where you attach this script to also has the Component "myScriptName" attached, it will also be processed, although it's not a child. To prevent this, you'd need the outer for-loop @Jordan suggested.

Is there a version of this in c#?

 foreach (ScriptName component in gameObject.GetComponentsInChildren<ScriptName>())
 {
      component.blah = true;
  }

Thanks :) This saved me loads of time. I thought if I couldn't get this to work I'll would have to do it through variables :D
