Hi all. As the title says. I seem to not find it, or does nothing like that exist?

 

If this requires some short of loop, some help on that would be also needed since I don't get looping scripts . At all.

Alright, right after I saw this I found the SetWeaponVisibility function. I guess that should do. But how can I Get all creatures in area?

hi Andy,

loops.

look at some code like this:

object oCreature = GetNearestObject(OBJECT_TYPE_CREATURE, OBJECT_SELF, 1);
SetWeaponVisibility(oCreature, 0, 0);

oCreature = GetNearestObject(OBJECT_TYPE_CREATURE, OBJECT_SELF, 2);
SetWeaponVisibility(oCreature, 0, 0);

oCreature = GetNearestObject(OBJECT_TYPE_CREATURE, OBJECT_SELF, 3);
SetWeaponVisibility(oCreature, 0, 0);

the only thing that changes is the iterator. Using a loop:
 

int i = 1;
object oCreature = GetNearestObject(OBJECT_TYPE_CREATURE, OBJECT_SELF, i);
while (GetIsObjectValid(oCreature))
{
    SetWeaponVisibility(oCreature, 0, 0);

    i++;
    oCreature = GetNearestObject(OBJECT_TYPE_CREATURE, OBJECT_SELF, i);
}

ps. something like this for the situation as described:

object oCreature = GetFirstObjectInArea();
while (GetIsObjectValid(oCreature))
{
    if (GetObjectType(oCreature) == OBJECT_TYPE_CREATURE)
    {
        SetWeaponVisibility(oCreature, 0, 0);
    }

    oCreature = GetNextObjectInArea();
}

I see. This makes things a bit more clear, thanks KevL. One question about loops, why do we need this while line at the beginning? I mean, what would happen if it wasn't there but the rest of the script were as it is now?

[Dann-J]

The 'while' function *is* the loop. Without that, things would only happen once (which is the antithesis of a loop).

 

Oh for the good old days of Basic programming, with its gotos and gosubs...

with its gotos and gosubs...

gaah!

read it like,

while (condition is TRUE)
// do this
// and dont forget to increment advance the condition before the next loop!!!
// or break; to put a sudden stop to the loop, and continue outside its scope.
// speaking of continue; use this to skip the current iteration and move onto the next iter.

It makes sense now. It's a good thing to know, these loops . And I guess any function which uses a GetNext*** can be used like that?

[kevL]

yep. when GetFirst* is called, the engine keeps its own little table of what "next" should/ will be ...
