Is selected Command.

Is there a command, That when you select a unit, Any Unit, It will call a trigger?
I would prefer it be in jass, but gui is fine too. any Idea. I cant seem to figure it out.

TriggerRegisterPlayerUnitEvent(<trigger>, <Player>, EVENT_PLAYER_UNIT_SELECTED, <True-Filter>)

Should cover it.

Much thanks Ill Give it a shot.

I dont understand how to use it.
TriggerRegisterPlayerUnitEvent(???, Player(0), EVENT_PLAYER_UNIT_SELECTED, ???)
So If I want it to call a function in my code, how would I do that? Also I dont understand the true-filter.

There is also an event when a player deselects a unit, it much the same as above only the blue constant part is another one.

??? - You'll need a trigger to register the event to:

function Init takes nothing returns nothing
    local trigger t = CreateTrigger()
    call TriggerAddAction(t,function A_FUNCTION_IN_MY_CODE)
    call TriggerRegisterPlayerUnitEvent(t,Player(0), EVENT_PLAYER_UNIT_SELECTED,???)
endfunction

??? - You'll need a "filter" for what units the trigger will fire on. Basically, you have to pass it a function that returns a boolean. If you want the selection of GetFilterUnit() to fire the trigger, return true. Else, return false.

function SomeFilter takes nothing returns boolean
    return true
endfunction

function Init takes nothing returns nothing
    local trigger t = CreateTrigger()
    call TriggerAddAction(t,function A_FUNCTION_IN_MY_CODE)
    call TriggerRegisterPlayerUnitEvent(t,Player(0), EVENT_PLAYER_UNIT_SELECTED,Filter(function SomeFilter))
endfunction

You can also use "null" instead of [ljass]Condition(function SomeFilter)[/ljass], as that has the same effect as returning true for all units. For this example, using null would make more sense.

Ok I am pretty Sure that cleared everything up. Thanks Alot.

 

[rover2341]

How Do I get what unit was selected?

 

[Nexor]

[ljass]GetTriggerUnit()[/ljass] will get it
