Timers

[crehym]

Question 1: Isn't there any search function here? sorry I'm new here

Question 2: How would you attach units to timers? Can I get the format, I'm just self study in jass and still a newbie.. I wanted to make my spells MUI so I shouldn't use globals.. I mean, you create a timer, store a unit/anything to it, run the timer and you're stored unit is there.. I just can't get it to work

Tnx guyz

A 1: Yes. Its called 'Search'.

A 2: Why would you use global units in jass, and not Local units?

 

[crehym]

Yea I should use locals, and how would you do that? I mean Use locals to timers? ~__~

 

[TheBlooddancer]

Im no Jasser, but i suppose that there is some local timer t function. Try it, if it gives syntax, then there isnt.

 

[crehym]

Nope..
Mm okay..
I mean attaching a unit to the timer

like call SetHandleHandle (WTF, WTF, WTF, WTF)

And then getting it into the function callback..

I really dunno..

Edit: Found the search function ^^

Congrats on finding the Search, and thanks for reading the rules (Edit).

And sorry, i dont think i can help ya.

You can do that... Um. You will need to store the unit data in the game cache... OR well thats how I would do it and it would still be MUI. I use CS_CACHE which has several such functions.

You will need. Dam. I can't remember how to store data in the Game Cache. But you will do it like this..

You will need to create a game chache and set the variable gamecache to the game cache you created

then your functions:

function H2I takes handle h returns integer 
return h
return 0
endfunction

function AttachObject takes handle h, string s, handle h2 returns nothing
if h2==null then
call FlushStoredInteger(gamechache,I2S(H2I(h)),s)
else
call StoreInteger(gamechache,I2S(H2I(h)),s,H2I(h2))
endif
endfunction

function GetAttachedUnit takes handle h, string s returns unit
return GetStoredInteger(gamechache,I2S(H2I(h)),s)
return null
endfunction

This allows you to attach a unit on a time by calling AttachObject the handle is the thing you attach your variable too. This "thing" can be any unit, timer, destructable, trigger .... Secondly you have a string. This is your "save name" in a way and is used later on. Lastly you have the unit you are attaching.
Now how to use in your example:

function Timer take nothing returns nothing
local timer t=GetExpiredTimer()
local unit u=GetAttachedUnit(t,"u") // Gets the attached unit saved under "u"
call AttachObject(t,"u",null) // This deletes the attached unit
endfunction

function SpellCast takes nothing returns nothing
local unit u=GetSpellAbilityUnit()
local timer t=CreateTimer()
call StartTimer(t,2,false,function Timer)
call AttachObject(t,"u",u) // Stores a unit under u on the target
endfunction

Umm. I hope you understand since my explanation is quite crappy.
