stopping a loop in a loop?

[takethat]

is that posible in gui to stop a loop inside that loop?

for example, a loop is going to loop for 10 times, but in certain circustances, the loop need to be stop at the fifth time

I think u cant stop the loop in the loop actions
Stopping must be outside the loop actions

 

[Nexor]

yes, you can in JASS, using the exitwhen line

example

local integer i = 1
local integer exit = 10

loop
exitwhen i >= exit
if IsSunnyDay(today) == true then
set exit = 5
endif
set i = i + 1
endloop

yeah, i understand jass can do so, but i asking is there a way to do so in GUI?

 

[Nexor]

you are able to use the custom script function in GUI to create JASS lines.

• Untitled Trigger 001
  • Events
  • Conditions
  • Actions
    • For each (Integer A) from 1 to 10, do (Actions)
      • Loop - Actions
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • (Triggering unit) Equal to (Attacked unit)
          • Then - Actions
            • Custom script: set bj_forLoopAIndex = bj_forLoopAIndexEnd - 1
          • Else - Actions

If something returns true then the custom script will set the loop index to end index -1 because the increment comes last in Integer A loop. This will make it break the loop!

• test grap
  • Events
    • Unit - A unit Begins casting an ability
  • Conditions
    • (Ability being cast) Equal to Test Grap (E)
  • Actions
    • For each (Integer A) from 1 to 10, do (Actions)
      • Loop - Actions
        • Game - Display to (All players) the text: (String((Integer A)))
        • Wait 1.00 seconds
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • Test Equal to True
          • Then - Actions
            • Custom script: set bj_forLoopAIndex = bj_forLoopAIndex - 1
          • Else - Actions

this results in the loop keep repeating on the same number, i use show text to show the number of integer A,

as the test equal to true, the loop repeat non stop.


edit: i change abit the trigger, it seems working as the number only show 1 when the spell is cast and Test is equal to True.

though i need some 1 to varify if this is right.

• test grap
  • Events
    • Unit - A unit Begins casting an ability
  • Conditions
    • (Ability being cast) Equal to Test Grap (E)
  • Actions
    • Set Int_Temp = 10
    • For each (Integer A) from 1 to Int_Temp, do (Actions)
      • Loop - Actions
        • Game - Display to (All players) the text: (String((Integer A)))
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • Test Equal to True
          • Then - Actions
            • Custom script: set bj_forLoopAIndex = udg_Int_Temp
          • Else - Actions
        • Wait 1.00 seconds

err... I think this would work, too.

• Custom script: exitwhen true

• test grap
  • Events
    • Unit - A unit Begins casting an ability
  • Conditions
    • (Ability being cast) Equal to Test Grap (E)
  • Actions
    • Set Int_Temp = 10
    • For each (Integer A) from 1 to Int_Temp, do (Actions)
      • Loop - Actions
        • Game - Display to (All players) the text: (String((Integer A)))
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • Test Equal to True
          • Then - Actions
            • Custom script: exitwhen true
          • Else - Actions
        • Wait 1.00 seconds

err... I think this would work, too.

I though about telling him to use one of thoose, but, can a loop have two exitwhen's? seems like it would cause issues, converted the loop will already have one, telling it exitwhen Integer A = Int_temp as you named the variable.

• Custom script: set bj_forLoopAIndex = bj_forLoopAIndexEnd - 1

This would simply set the current Integer A to AIndexEnd - 1, because converted the last Integer A = integer A + 1 comes after, making it stop when this is run.

Mind explaining?

'exitwhen true' is fine. It'll exit the loop at the point of the custom script.

The GUI loop already has an exitwhen condition, adding another one made me think there would be issues, don't really know why, just seemed like it

Huh:

function Trig_Untitled_Trigger_001_Actions takes nothing returns nothing
    set bj_forLoopAIndex = 1
    set bj_forLoopAIndexEnd = 10
    loop
        exitwhen bj_forLoopAIndex > bj_forLoopAIndexEnd
        if ( Trig_Untitled_Trigger_001_Func001Func001C() ) then
            exitwhen true
        else
        endif
        set bj_forLoopAIndex = bj_forLoopAIndex + 1
    endloop
endfunction

But it didn't display any errors, so It seems fine, my thoughts were basically the same as you don't add two "else" in an if statement, note "else" not "elseif".

You can have 23 'exitwhen not (false and not (true != false))' for all I care.
I don't think there's any realistic limit on the amount of exitwhen's.

sorry i didnt make it clear, but

• Custom script: set bj_forLoopAIndex = bj_forLoopAIndexEnd - 1

doesnt work, since i put a wait in my trigger when testing, it didnt goes into infinite loop, but as it show the same number over and over again, i guess it WILL lead into an infinite loop.

using integer variable method solve the case, and exitwhen also work fine.

i think when exitwhen = true, it escape the loop.

so its like a maze can have multiple exit.

anyway the problem is solve.
