Set child gameobject active?
How can you set the child of a gameobject active I have tried
gameObject.transform.child.gameObject.SetActive(true);
But I get the error
NullReferenceException: Object reference not set to an instance of an object Boo.Lang.Runtime.RuntimeServices.GetDispatcher (System.Object target, System.String cacheKeyName, System.Type[] cacheKeyTypes, Boo.Lang.Runtime.DynamicDispatching.DispatcherFactory factory) Boo.Lang.Runtime.RuntimeServices.GetDispatcher (System.Object target, System.Object[] args, System.String cacheKeyName, Boo.Lang.Runtime.DynamicDispatching.DispatcherFactory factory) Boo.Lang.Runtime.RuntimeServices.GetProperty (System.Object target, System.String name) UnityScript.Lang.UnityRuntimeServices.GetProperty (System.Object target, System.String name) BuildZone.Update () (at Assets/my assets/Scripts/BuildZone.js:24)
the script was attached to the parent of the object I was trying to make active How can I make the object active?
Transform has no child property, so this should not even compile...
To access children of a Transform, please use:
for (var child : Transform in transform)
{
if(....) // check if this is the child you want to activate, by name, tag or anything else
{
child.gameObject.SetActive(true);
}
}
If you have one child only, then of course you can skip the if statement. You can also access a child by its index using GetChild method.
Assets/my assets/Scripts/BuildZone.js(24,33): BCE0005: $$anonymous$$ identifier: 'child'. is this C#?
Nope - it's javascript. Could you post related lines from your code?
here is part of the script
function Update ()
{
if(inBuildZone)
{
if(INV.sticks >= 30 && Input.Get$$anonymous$$eyDown ("r"))
{
Debug.Log("Build house");
child.gameObject.SetActive(true);
}
}
}
the Debug.Log is called. does it matter if the game object with the "child.gameObject.SetActive(true);" is also a child?
Did you declare/assign child variable? In the sample code from my answer, child is both declared and assigned as part of for loop.
And regarding your question - it doesn't matter.
