How to hide and unhide units in an area?

How to hide and unhide units in an area?
I tried but I defeated. Please help.

 

[FeelsGoodMan]

Usually I just add them to a unit group and then pick all units in that unit group.

 

[matin45]

I can do this but when you want to unhide them you can't, why?

This works fine:

• Hide
  • Events
    • Player - Player 1 (Red) types a chat message containing hide as An exact match
  • Conditions
  • Actions
    • Set HideGroup = (Units in Region 000 <gen>)
    • Unit Group - Pick every unit in HideGroup and do (Actions)
      • Loop - Actions
        • Unit - Hide (Picked unit)

• Unhide
  • Events
    • Player - Player 1 (Red) types a chat message containing unhide as An exact match
  • Conditions
  • Actions
    • Unit Group - Pick every unit in HideGroup and do (Actions)
      • Loop - Actions
        • Unit - Unhide (Picked unit)

Hidden units are omitted from many triggers, which is probably the reason you are facing some difficulties.

Yes I use it all the time.

 

[matin45]

oh i'm so sorry, this is also works with time?
like a 120 second wait?

 

[FeelsGoodMan]

Should work yes. Can you post the trigger you're trying to make work?

• Untitled Trigger 001
  • Events
    • Player - Player 1 (Red) types a chat message containing hide as An exact match
  • Conditions
  • Actions
    • Set hg = (Units in Region 000 <gen>)
    • Unit Group - Pick every unit in hg and do (Actions)
      • Loop - Actions
        • Unit - Hide (Picked unit)
        • Wait 5.00 seconds
        • Trigger - Run Untitled Trigger 001 Copy <gen> (checking conditions)

• Untitled Trigger 001 Copy
  • Events
  • Conditions
  • Actions
    • Unit Group - Pick every unit in hg and do (Actions)
      • Loop - Actions
        • Unit - Unhide (Picked unit)

Not sure why that doesn't work but do this instead, it works fine and does what you need:

• Hide
  • Events
    • Player - Player 1 (Red) types a chat message containing hide as An exact match
  • Conditions
  • Actions
    • Set HideGroup = (Units in Region 000 <gen>)
    • Unit Group - Pick every unit in HideGroup and do (Actions)
      • Loop - Actions
        • Unit - Hide (Picked unit)
        • Countdown Timer - Start UnhideTimer as a One-shot timer that will expire in 5.00 seconds

• Unhide
  • Events
    • Time - UnhideTimer expires
  • Conditions
  • Actions
    • Unit Group - Pick every unit in HideGroup and do (Actions)
      • Loop - Actions
        • Unit - Unhide (Picked unit)

Thanks friend

 

[FeelsGoodMan]

You're welcome.

@matin45 The reason the units do not get hidden is because waits do not work in the loops from "pick all units" and "pick all players". Actions that come after the wait will never happen.

Another solution would have been to run a trigger inside the loops. Then the trigger will call the wait and the other actions after it.

• Hide
  • Events
    • Player - Player 1 (Red) types a chat message containing hide as An exact match
  • Conditions
  • Actions
    • Set HideGroup = (Units in Region 000 <gen>)
    • Unit Group - Pick every unit in HideGroup and do (Actions)
      • Loop - Actions
        • Unit - Hide (Picked unit)
        • Trigger - Run UnHide <gen> (not checking conditions)

• UnHide
  • Events
  • Conditions
  • Actions
    • Wait 5.00 seconds
    • Unit - Unhide (Picked unit)

No need to start a timer or a wait for each unit in the group... just do what matin tried but with the wait and trigger execution outside the loop....

• Untitled Trigger 001
  • Events
    • Player - Player 1 (Red) types a chat message containing hide as An exact match
  • Conditions
  • Actions
    • Set hg = (Units in Region 000 <gen>)
    • Unit Group - Pick every unit in hg and do (Actions)
      • Loop - Actions
        • Unit - Hide (Picked unit)
    • Wait 5.00 seconds
    • Trigger - Run Untitled Trigger 001 Copy <gen> (checking conditions)

• Untitled Trigger 001 Copy
  • Events
  • Conditions
  • Actions
    • Unit Group - Pick every unit in hg and do (Actions)
      • Loop - Actions
        • Unit - Unhide (Picked unit)
