Here is how to make classes for your map.
Take a lifecycle and wire it to a relay for all players.
Wire the relay to a popup that has two actions.
Set all the popups to player scoped.
Set the popup to show when receiving “back”
Set the popup to hide when receiving “sniper class chosen”
For the popup, one action should be named “sniper” and broadcast “sniper class chosen” (or whatever you would like)
The 2nd action named “next” doesn’t broadcast anything.
Then add another popup.
Set the popup to hide when receiving “medic class chosen”
Set the 1st action to “medic” and have it broadcast “medic class chosen”
Then, set the 2nd action to “back” and have it broadcast “back”
WIRING
wire the relay to the 1st popup and have it “relay” ----) “open popup”
wire the 1st popup to the 2nd popup and have it
“2nd option chosen” ------) “open popup”
Grab an item granter (choose whatever item you want) and wire the 1st popup to the item granter like this… popup “1st option chosen” -----) grant item
wire the 2nd popup to another granter and wire it like…
popup “1st option chosen” -----) grant item
