Nets

[Mind]

In the level I'm making, there are some (Blood) Elves imprisoned by Ice Trolls. (that says enough: my level is about Kael in Icecrown Glacier )
The Blood Elves must be imprisoned by Troll Nets. If you rescue them, they should be freed from their nets.
I tried everything: I even searched in a book about Real Basic about variables. (yes, Real Basic also has variables)

First imprisoned unit
Event: Unit is rescued
Action: Delete (variable) ensnare
(variable value ensnaretarget = last created special effect)

("Woohoo! It's working!")

Second imprisoning unit
Event: Unit is rescued
Action: Delete (variable) ensnare
(variable value ensnaretarget = last created special effect)

("Damn, it's not working.")

Of course, there can only be one "last created special effect"

 

[OrcRush]

So just make it not the "last created effect". I'm sure there's a variable here somewhere that's made to do that, they do it all the time in the blizzard campaigns...

 

[Mind]

I can't stipulate the initial value.

Variable type - Special effect
Initial Value - None (unchangeable)
Set Variable - ensnaretarget = last created special effect

you must be creating the ensnare nets at some point in the game right? that's when you should be assigning the sfx into variables. And make ensnaretarget an sfx variable array, so you can assign all the net sfx's into the variable.

 

[Mind]

Uh…_Assigning an sfx array in a special effect variable? Err, what are arrays for anyway? I don't get it, I'm to dump.

 

[Darg]

arrays are very similar to normal variables, its just that you can store multiple things in them.

e.g. for an integer array you might do this:

set SomeInteger[0] = 1
set SomeInteger[1] = 2
set SomeInteger[2] = 5
set SomeInteger[3] = 2
set SomeInteger[6] = 82

special effects arrays are no different:

special effect - create <ensnarenet.mdl> on <some troll>
ensnaretarget[0] = last created special effect
special effect - create <ensnarenet.mdl> on <some other troll>
ensnaretarget[1] = last created special effect



and when it comes time to destroy them:

special effect - destroy ensnaretarget[0]
special effect - destroy ensnaretarget[1]

Omg, I suck… I had so many difficulties and work to try to solve this problem, and now it suddenly occurs to me that a cage is 10 times easier and perhaps better.

Still, thank you very much for this information. This solved the greatest problem I had with variables… Perhaps the only one.
