z bug

[Warcaptain]

(from me and er1c)

i posted on npc-server about a bug where my arrow was layed about half the distance from where it landed
but this was because i put playerz-15 in the script for the startz
i THOUGHT this would make it shoot from 15 above the players z

but instead for some reason it made it shoot 15 spaces back each dir.

whats the problem
