[Trigger] Countdown on top of a unit's head

modafoka · Oct 3, 2010

i am updating an old map of mine that has a spell thats suppose to kill a unit within 60 seconds. it would display a countdown timer on top of the unit's head in a descending order. I thought of doing this with floating text, however, i am not sure on how to attack the floating text to the unit's head with triggers. Any thoughts on the matter? Thanks in advance.

floating texts can change dynamically???

Thank you very much for the quick reply. I will put it to good use soon! (i found my old tetramaster map and i am currently updating it).

EDIT: it actually didn't work

You need a periodic trigger that keeps destroying and recreating Floating Text on top of the unit.

Floating Text - Change (Last created floating text): Enable permanence

Is it Disable permanence ?

That solves the issue of the text updating as time passes by but it doesn't remain attached to the unit's head. Like GhostThruster said, you need to keep destroying it and creating it, however, a unit doesn't take one step every 1 second, it takes at least 2 to 3 steps depending on the speed, thus leaving the floating text behind for at least 0.30 seconds making it seem choppy. Currently trying to find a solution.

oh.. just move it to unit's loc, make sure you destroy leaks!

Either this:

Events
- Unit - A unit Begins casting an ability
Conditions
- (Ability being cast) Equal to Your Ability
Actions
- Set Timer = 120
- Set Unit = Targeted Unit of Ability Being Cast
- Trigger - Turn on (Second Trigger)

Second trigger:

Events
- Time - Every 0.50 seconds of game time
Conditions
Actions
- Set Timer = (Timer - 1)
- Floating Text - Create floating text that reads (String(Timer/2)) above (Unit) with Z offset 0.00, using font size 10.00, color (100.00%, 0.00%, 0.00%), and 0.00% transparency
- Floating Text - Change (Last created floating text): Disable permanence
- Floating Text - Change the lifespan of (Last created floating text) to 0.50 seconds
- If (All Conditions are True) then do (Then Actions) else do (Else Actions)
  - If - Conditions
    - Timer Equal to 0
  - Then - Actions
    - Unit - Kill (Unit)
    - Trigger - Turn off (This trigger)
  - Else - Actions
    - Do nothing

in the first the timer is 120 but it changes every 0.50 seconds and it's still 60. The text in the Floating Text is a Integer Converted to String with an Arthimetric Timer/2 because of the timer 120 not 60.

Or this, as Mortar said:

Events
- Time - Every 0.50 seconds of game time
Conditions
Actions
- Floating Text - Change the position of Text to (Unit) with Z offset 0.00

Hope it helps

and we have a winner! Rep for everyone that helped!
I need to relearn everything once again and clean the mess of codes in my old map, thank you all for showing me the way.

EDIT: does it work the same if the ability is in an item ability instead of a hero ability?
EDIT: I also noticed that if you kill the unit while the countdown is still going it remains visible even after the unit is dead, can i set then a trigger that checks if the unit is dead to remove the timer?
