Store units in gamecache

03-09-2007, 12:38 PM

well, i tried to search for this problem, but i didnt get any pleasant results. So i just opened another thread going to bore you ^^

So, i have a problem, you can store integers, reals and so on in gamecache, but why cant i store units? i cant refer to "GetStoredUnit", this isnt marked as a function, so what shall i type instead?

or is there a trick?

i would like to thank everybody helping me,

Skater	You can use H2I and then u save this integer in the gamecache. JASS: function H2I takes handle h returns integer return h return 0 endfunction To get the unit u use I2Unit JASS: function I2Unit takes integer i returns unit return i return null endfunction e: Hey anx^^

anXieTy	Code: function I2Unit takes integer i returns unit return i return null endfunction Why I2Unit and not I2U?

Skater	Hmm i dont know. You can name your function also to "bla" or what ever you want.

Blubb-Tec	because names are unimportant^^ no but as i told u, use handle vars! they do the same what you want, but take the work of you..

You must use the "Return Bug". There are a LOT of articles about this "bug" (look at this and this).
Basically you don't need to store a unit, but an integer which is a sort of "pointer" to that unit:

JASS:

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

Units (just like locations, groups, points etc...) are "handles" and, using the function above, you can obtain an integer which is a sort of a pointer to that handle.
To get your stored unit again you will need a function like I2Unit, converting your integer in your unit again.
It is better that you read the articles. I hope it helped. Cheers.

botanic	Also however i dont recomend using the game cache if at all possible because it can cause problems with memory leaks...
