Well it would be the right thing to do would it not, because what if he doesn't wan't others to use the code?
I remember many people getting in trouble for stealing code.
Stealing code is only really a problem when you almost literally copy paste an other mod with minor changes.
Many coders have written supportive code/scripts which will be no problem to use.
If you would have to ask for every bit of code you copied, if you could use it, there would be like 200% more PM's sent daily.
Or something like that.
Any way, it is better to start from scratch for this.
You can't really use Bushi's script without really knowing how it works.
Which might be kind of hard for someone like the OP, no offence. :)
Just a guess since:
Sorry, I'm not too good at scripting. If anyone wishes to do it for me, feel free to use it.
