SetActiveRecursively(true) replacement in Uinity4.
When I use "gameobject.SetActive(true)" in unity 4, it just act like "gameobject.active = true" in unity3d 3. How can I do "gameobject.SetActiveRecursively(true)" in unity 4?
I found a reason why it can't set active recursively, Because there is a child under that node have set to be inactive. And there are no option to force the tree to be active too. If this is not a bug, there should be a function to get all gameobject under a node and set everything active.
The change in paradigm in how active works can be tough on pre Unity 4 projects... but switching things to work in the new way is worth it. Everything makes more sense.
I said it act like unity3d because I don't know the only node under it was set to inactive by accident. But there should be a way to force a tree to active or not, other wise there will be even more bugs about setActive because some accident setting in children.
Generally you'd use SetActive in Unity 4, but in those cases where you really need an exact replacement, then you can make your own function:
function SetActiveRecursively (go : GameObject, active : boolean) {
go.SetActive (active);
for (var t : Transform in go.transform) {
SetActiveRecursively (t.gameObject, active);
}
}
Not as handy as before, but this do the job. Thx for your code.
Here's a version that lets you call it directly from a gameObject in c#:
public static class MyExtensions
{
//bring this back to Unity4
public static void SetActiveRecursivelyLegacy (this GameObject go, bool active)
{
go.SetActive(active);
foreach (Transform t in go.transform)
{
t.gameObject.SetActiveRecursivelyLegacy(active);
}
}
}
