Parent alpha affect children

I'm trying to fade my interface in when the mouse goes over it by using a lerp on the alpha. But the panel alpha does not affect the children UI elements. How can I accomplish this? Thanks.

 

Your gonna have to change each one individually I imagine. Like maybe have groups of them in methods that fade them in sets if you need to, but really the parent child relationship of objects doesn't carry over any changes directly from parent to child (well I guess transform doesn't count) unless you code it to do so. Make variables for each object in the interface, and fade them one at a time (even if there's methods like FadeTopGroup() that handles groups of them at a time).

Good luck!

 

You can put a Canvas Group on the parent object and change that component's alpha. It will change the alpha of the parent object and of all its children that have Image components at the same time.

Parent (with Canvas Group)
-- Child1
-- Child2
-- -- ChildOfChild1

All will have their alpha value changed.

 

Awesome, thanks!

 

Oh, I didn't know that, thanks @BinaryX

 

BUMP

Is there a way to do this for non UI gameobjects that have Sprite Renderers? Have the parent control the alpha of all children?
