GetComponents vs GetComponentsInChildren
Hello guys !
I just encountered a little problem with these two functions, so I went to the online doc and I saw a really important difference : GetComponents seems to work on inactive game objects, contrary to GetComponentsInChildren ...
Is there an easy way to get the components in children of an inactive game object ?
Simply traverse the children and use GetComponents() on each one.
If you want to get all the rigid bodies for example:
ArrayList components = new ArrayList();
foreach (Transform child in transform) {
components.AddRange(child.gameObject.GetComponents<Rigidbody>());
}
How do you traverse the children in an inactive gameobject ?
An easy way could be to activate it, find my components, and deactivate it, but I think it is very ugly ...
Did you test my code? I think it traverses all active or inactive gameobjects. Otherwise how would you find the inactive children in order to activate them?
Actually I'm looking for audiosources in a gameobject children to impact their volume. But I don't want to activate anything.
The code I will make can be called a lot in a really short time (it will be plugged to a slider), so I need it to be as quick as possible.
I'll try your code to test if this works.
Depending on the Unity version you're using you can simply pass an additional parameter which will include inactive objects as well:
GetComponentsInChildren<Renderer>(true)
Oh my... I didn't even see the optional parameter ... thanks
