Maze, Circle Revival

In my new maze I would like to have a revival system similar to that in Escape Shroom World. This system is that when you die a circle of power of your player color is created at the point where you died, and when another live player steps on your circle of power you are revived at where your circle was.
However, I do not have any idea on how to go about triggering this. Does anybody know how to do this or know of a tutorial somewhere on how to do this?
Thank you.

Download one of those run kitty run-maps and nick it from there. Most of them (at least the old ones) are unprotected.

oh thats a good idea, ill try it

A little OT, but that signature of yours is... Distracting, lol. As for on-topic, it's quite easy. You pretty much said how to make your own trigger within your own post. You have it exactly, actually. All you need to do is find what you need in the drop-down menu's in the GUI. Takes a bit of experience, but once you get how Blizzard organized the menus, it'll be easier for you to navigate and get exactly what you want done.

Decided to give it to you anyways.

Event: A unit Dies
Condition: dying unit is equal to Footman
Action: Create 1 Circle of Power at Position of Dying Unit
Set CoP[Player Number of Dying Unit] = True

Event: Unit comes within 100 of Circle of Power
Condition: Unit is Friendly
Action: Create 1 Footman at position of Circle of Power
Remove Circle of Power

You might want to change it so they respawn elseware. If they die by touching a region, and then are revived in the exact spot they died in, they will just die again.
