OnEnter script question

[R2-X2]

And again a scripting question:

 

How two make scripts that check if an NPC already exists in a module, check a GlobalNumber (or two) and if the NPC doesn't exist and the GlobalN. is right, spawns an NPC? And, is there a way to do it with multiple NPCs in one script?

[zbyl2]

Add this to your OnEnter script, it will check if NPC was already spawned in module and if globals were set:

      if(GetGlobalNumber("NAME_OF_YOUR_GLOBAL") == X // Global number equals X
       && GetGlobalNumber("NAME_OF_SECOND_GLOBAL") == X // cause you asked for two globals 
       && !GetIsObjectValid(GetObjectByTag("TAG_OF_YOUR_NPC"))) { // only if NPC doesn't exist in module

              CreateObject(OBJECT_TYPE_CREATURE, "YOUR_NPC", Location(Vector(0.0, 0.0, 0.0), 0.0f));    //remember to change tag of your NPC and coordinates
         }

 

 

 

Hope that helps : )

Yep that helps. Thank you.

If I want to use just one of these conditions, I just would have to put an "//" (without the quotes, sure) in front of them, or, if I don't use the first one change the "&&" to an "if", right?

[zbyl2]

You may completely remove line you don't want. And yeah, if you don't want first one you'll need to replace && with "if(" later.

Ok, everything cleared, thanks!

[R2-X2]

Your script doesn't work. I always get a syntax error at "if"

[zbyl2]

I can compile it.

Did you add "void main() {" at the very beginning? Like this one:

void main(){
     if(GetGlobalNumber("NAME_OF_YOUR_GLOBAL") == X 
       && GetGlobalNumber("NAME_OF_SECOND_GLOBAL") == X 
       && !GetIsObjectValid(GetObjectByTag("TAG_OF_YOUR_NPC"))) { 

              CreateObject(OBJECT_TYPE_CREATURE, "YOUR_NPC", Location(Vector(0.0, 0.0, 0.0), 0.0f));  
         }
}

It's always needed to add void main() at beginning of all your scripts (except they're conditional scripts for conversation, but well), otherwise you won't compile anything.

[R2-X2]

ouch. I always forget it.

Everything should be cleared now.
