Im trying to make an arena like map where players will start at the same time, so I decide to make a kind of gate what will open in the same time by trigger or Zeus option. It can move or be erased, is any way to do that? And can I add a thunder stike (or any other signal) when it happend?

Hem... Have you any idea about what you are doing ? Your post is very imprecise. What is the "gate" you are talking about ? How is it spawned in game ? In order to make all players start at the same time you only have to disable JIP. And what is this thunder strike doing up there ? Any link to the "gate" ?

I mean a few VR walls or somewhat (just spawned in the editor as an object) what will be removed at the same time because players need a time to choose an equipment. Then the "gates" are opening at the same time.

In the video I'll show you how you can delete walls without scripts just with a simple trick. Whenever you do this as mentioned above it is a bit vague so I'll used an addaction but that could also be done by just killing the unit instead with zeus. Like you could add a timer let it countdown for xx minutes and then let the trigger do hes thing.

The thing is because I named the walls I can easily delete them with:
Now its just a thing of thinking up which way you want the trigger to shoot.

This is exactly what I need, thank You very much!
