This is actually not that complicated of a trigger, First make a
Variable and name it lives(or whatever), make it an integer and set its value to however many lives you want the people to start with. Then make a rect , make this rect the place you want the ppl to lose lives if a unit from a player enters it. Now to the Trigger part, first let me just say i cannot be exact about the trigger names because i am not on my home machine...
Event- A unit enters (specified rect)
condition- If unit belongs to player(the player who gets the creeps who move in the td)
Action- Set Variable (lives) ; (lives) - 1
Remove (Triggering or Entering[both will work]) unit
-----------------------------------------------------------------------
Then make a new trigger, this will be for when lives reaches 0, the players will lose.
Event- Periodic;every 1.00 seconds of game time
Action- If/Multiple actions/else
if- (lives = 0)
then- (you can display whatever here but lets just go with this...)Make the player lose the game[again i cannot be specific about trigger name) and have it display the defeat message and make that whatever you want.
else- Do Nothing
------------------------------------------------------------------------
Now this is if you want it to be put on a multiboard, have the columns blah blah blah, have a column named lives and etc. make a new trigger....
Event- periodic;every 0.10 seconds
action-set text of (last created multiboard[this wont work if u have more then one multiboard]) to *convert integer to String of variable [lives] * Again sorry about not being specific but meh : /
Hope i helped with your issue
