Creating JASS Trigger Conditions

[hamsterpellet]

It's just a simple question. I think I heard somewhere that there are some restrictions of functions you can call or things you can do in general, when you are inside a Trigger Condition:

call TriggerAddCondition( gg_trg_MyTrigger, Filter( function Trig_MyTrigger_Conditions ) )

So, is there, in fact, some restriction inside:

function Trig_MyTrigger_Conditions takes nothing returns boolean

Or I am just crazy?

Thanks

well the only restriction in Conditions I know
is that it can take nothing and must return boolean

but thats it

and in structs , the condition method must be static but nothing else

don't realy know what you meant by restrictions

restriction:
you cant use wait in triggercondition

Thats about it

It doesnt even need to return anything using this:

function aaa takes nothing returns nothing
//blablabla
endfunction

function aab takes nothing returns nothing
    local trigger t = CreateTrigger()
    local code c = function aaa
    call TriggerAddCondition(t, Condition(c))
    set t = null

It doesnt matter if you use Filter or Condition, it does the same thing

This way returns false by default

Also you should ever return false in the function marked as condition for trigger(triggercondition) because if you return true he will try to execute his Actions(only if all triggerconditions returns true) and it takes a very little bit time to realise that he doesnt have any

I think a Condition that returns false by default is pointless (its like you make a trigger that never runs:/)

unless you run the trigger without checking Conditions (same as you don't have any Condition:/)

its not good to have triggeractions in Jass, everything is done in triggercondition because they are way faster then triggeractions

if you dont believe me test it yourself, add a triggercondition using the code trick to trigger abd add triggeraction to trigger and print something in them and you will see

actually Magtheridon's TriggerRegister idk what uses this method of adding a function to a trigger so you dont need to worry about returning booleans

 

[Lender]

ah so thats what you meant. good to know that

 

[Adiktuz]

yeah,we return false so that the trigger will not check the actions anymore... then we do eveything that needs to be done inside the conditions part because well, it runs first...
