Um, Ive been trying to figure out when ever I make an NPC to fight I hit it and its health goes down, but at 0.5 it just stays there even when I hit it does not do anything. So I wanted to come here and see if you guys know why

PHP Code:
// Graal2002 NPC by Stefan Knorr
if (created) {

showcharacter;
setcharprop #3,head20.png;
setcharprop #C0,yellow;
setcharprop #C1,yellow;
setcharprop #C2,white;
setcharprop #C3,brown;
setcharprop #C4,black;
setcharprop #n,London;
