How can I do the following things?

I need help with doing these things.

- Individual kill counts that are trackable by Leaderboard.
- Making an event happen when the Countdown Timer reaches a certain number(NOT expiring).
- Making a timer for a unit to explode, killing everything around it.
- Implimenting a voting system for extending a Countdown Timer.

Any help you could provide would be greatly appreciated. Thanks.

Because im at work, i cant answer eveything fully, but:

1. You need to make an interger array varible (for sake of explaining, lets call it Kills). Next you will need code to update the varible.
Actions: A Unit owned by Player (number of player to keep track of kills) kills a unit

Condition:
Nothing unless you want to limit who has to die or what unit makes the kill

Actions:

Set Kills[PlayerNumber(of triggering player)] = (using arthimatic) Kills[PlayerNumber(of triggering player)]+1
Update leaderboard using the new kill varible

2.I belive the countdown timer is not a real, but a interger value. So you would need to do a peridoc time check. say:

Events:
Every 1 second of game play

Conditions:
None

Actions:
Set (Interger varible) = Countdown timer
If (interger comparaison)Countdown timer=number, then (action) else (action)

3. would have to look it up

4.First make a interger varible called NumPlayers and a player group varible called AllPlayers (or anything you want it to be).
on the map initilazation actions:
-Player group remove all players from AllPlayers
-For Each interger A 1-(number of max players in your map) do If Player Slot Status is = to Is Playing, Then add Player(Interger A) to player group AllPlayers
Set NumPlayers = Count the number of players in AllPlayers
Then you can do this:
Events:
Player chat message contains 'string' as an exact match

Conditions:
none

Actions:
set Extend (interger varrible name can be anything) = Extend + 1
If (interger comparison) Extend greater than (arithmatic)NumPlayers/2 then (action) else (action)
