Canvas only at specific time visible

I’ve made a canvas that the gamer can “edit” his game-character. But I want this canvas just be visible at a specific time, on event, …
I haven’t get it working, using the remove and add trait node. Or by making the object itself invisible.

Did someone of you know, how to make a canvas visible/unvisible with nodes?

the last message is from Lobus. he says that he’s doing something to the canvas that you can show or hide some elements at some time.

maybe if you disable the trait with Haxe? I don’t know if its possible yet.

Oh, nice.
If I could program with Haxe I would try this. Now its time for me, to learn Haxe.
Thanks for the hint.
