I need to move several copies of the same NPC at the same time, in the same direction.

I read a page somewhere on the wiki about how to do this, but for the life of me I can't find it.

Here's the script I'm using to do this:
Code:


#This script is supposed to walk all copies of NPC 9 down 100 spaces at the same time.

plotscript,song,begin

variable(loop,green count,green note)

green note := NPC copy count(9)

for(loop,0,green count)
   
   do (

    green note := NPC reference(9,loop)

   
    walk NPC(green note,down,100)

   )

end


I have speeds set for the NPCs (at 4 if it matters), so I know they're able to move, but usually only the first copy actually does anything. Any ideas where I went wrong?

It looks like if you swapped the "green note" and "green count" variables in the for loop, it would work fine.

There's another bug:
Code:
for(loop,0,green count)

should be
Code:
for(loop,0,green count--1)

Otherwise, you'll find that "NPC reference(9,loop)" returns 0 for the extra "loop" value, which causes it to walk the first copy of NPC ID 0!

To understand why the "--1" is needed, realise that if there are 5 copies of the NPC, then they are numbered (for the purpose of the "NPC reference" command) 0, 1, 2, 3, 4.
