What affect the loading speed of a map?

[Jay the Editor]

I've been working on a map and I found out that my map load quite slow although the file size is small (400kb+).
Does the loading speed depends on the triggers that I used? Or it depends on how many triggers that I used?

Besides that, I used the below trigger in setup like map initialization and Multiboard initialization. Does the below trigger actually helps in reducing the lag during the game?

• Custom script: call DestroyTrigger( GetTriggeringTrigger() )

I mostly use that for local triggers that need to be destroyed afterwards. Destroying the Map Init trigger is pointless.

Oh I see. Btw, do you have any example on how to "use it for local triggers"? ><

[EDIT]: Is the amount of variables affects the loading speed of the map?

Well, let's say I want a trigger created specifically for the target unit of a spell. Instead of bloating a global trigger with multiple events, I can use a local one.

function A takes nothing returns nothing
    local unit u = GetTriggerUnit()
    //Actions Here
    call DestroyTrigger (GetTriggeringTrigger())
    set u = null
endfunction

function Actions takes nothing returns nothing
    local unit u = GetSpellTargetUnit()
    local trigger tri = CreateTrigger()
    call TriggerRegisterUnitEvent (tri, u, EVENT_UNIT_DAMAGED)
    call TriggerAddAction (tri, function A)
    set u = null
    set tri = null
endfunction

This example creates a local trigger for the target unit, with the event of "Unit takes damage". Once the unit takes damage, the trigger is not needed (if we wanted the unit to be damaged only once and trigger the effects), so we destroy it.

As for the variables, if you declare loads of them under the "Map Initialization" events, it will become slow indeed. Distribute them with the event of "Elapsed time game is 0.00 seconds".

Oh I see.
I just realise that my Map Initialization really full of the variables.
For the Jass script, I don't really get it because I know nothing about Jass script. Never mind, I'll try to learn it after my exam :3
Great! Thanks Pharaoh_ +rep

Since there was ton of threads like this, I'll just recommend reading that - it will help you reducing/optimizing the map (enter both 'this' links).

Loading time can be lowered by replacing event 'Map initialization' with Time - Elapsed time is 1.00 (it doesn't have to be exactly 1.00 second, you can enter any other value here too, but let it be small enought so triggers will be loaded 'at the begining of the game').

Oh alright. Thanks spinnaker +rep
