Attaching 'code' variable

04-01-2006, 08:20 PM

Using the handle functions, can I attach a code variable to something (a timer in this case)? Or maybe using tables or something else?

Edit: Woot, found a way to work around it, since the handle vars don't work with code variables. In case anyone's interested:
In my function I had certain events happen when the spell was cast, then a timer started which moved an object towards the target. When the object hit the target, I wanted a function to be run, which is the code variable. My problem was I couldn't find a way to get the code parameter from the first function into the handlerFunc for the timer.

What I did was create a second timer whose handlerFunc was the code parameter of that function. I set the timeout very low, almost instant, then right after it was created paused the timer. I then attached this timer to my first timer, so I could get it back later. Now when the object hits the target, I can simply use ResumeTimer() and the function will happen pretty much immediately. Haven't actually tested it yet..but it seems sure to work after some messing around.

Anitarf	You could also attach the function name as a string to your first timer and then use ExecuteFunc() to run it.

karukef	You can also attach a trigger. Just create a trigger, add your desired function as an action of that trigger, then attach the trigger, and retreive it/run it later on. I've used this for a system that automatically launches triggers whenever an ability is added to/removed from/used by a hero, and it's very intuitive.

TaintedReality	Ah thanks, using ExecuteFunc will be simpler, and I won't have to mess around with the timers so much. Edit: One problem, now I can't get any variables from function to function. I'll have to stick with timers or triggers.

You can pass variables to functions that "take nothing" using global variables or gamecache. I personally think gamecache is the easiest and most readable way of doing it.

JASS:

call StoreString(udg_cache, "your_funcname", "some_string_arg", "just a test")
call StoreInteger(udg_cache, "your_funcname", "some_integer_arg", 71)

call ExecuteFunc("your_funcname")

function your_funcname takes nothing returns nothing
    local string s = GetStoredString(udg_cache, "your_funcname", "some_string_arg")
    local integer i = GetStoredInteger(udg_cache, "your_funcname", "some_integer_arg")

    //Do stuff
endfunction

TaintedReality	I just used the timer method, with handle vars. Works perfectly.

Thats worse than the usage of a timer, because you always must get rid of the triggeraction. All in all I prefer the >call ExecuteFunc("funcname")<.

Vexorian	blerg JASS: function C2I takes code c returns integer return c return 0 endfunction function I2C takes integer i returns code return i return null endfunction

TaintedReality	Oh. That was easy enough, I thought I was being all tricky with the timer thing but I guess not =P.
