Decrease Time with ability?

[T3rm1nat0r]

Hi everyone, how do i make an ability that decreases a timer by 30 seconds? What i am saying on my map you play for 30 minutes and you build a certain building which has the ability to decrease time by 30 seconds. So when i activate it my timwerwindow minuses by 30 seconds, does any body know how to do this? And how do i make it cost 1000 + 250 per each certain living units?

I am willing o give +rep to those who know how to do it

just make a variable that stores the time and do it minus the other time make sure it is always null and when you got the abilty it is 30 so when it isn't cast it is - 0 so it stays the same.

and for the second store them into a unit group do that x 250 and +1000 and here you go.

variables needed:

-Time real variable
-Timer Timer Variable
- Integer array variable
- Unitgroup variable

I'd say make an integer variable which stores the seconds. Then when you build this building just do:

Actions:
 Set TIMEVARIABLE = TIMEVARIABLE - 30

If you use a variable instead of a time you'll have to add this trigger to your map also:

Event:
  Every 1 second 
Actions:
 Set TIMEVARIABLE = TIMEVARIABLE - 1

@rodead: Are you sure that this timer will work correctly? I'd say that the timer - once started - will not be affected by the variable Time anymore, don't really know, though

you better not use a integer variable real is better in this case since timers works with them.
