Custom Projectile (Bow)

[E_Man]

I'm trying to make a custom bow with new images for my world, I found a script online that uses the command I need: "shoot" but I could not find it in the commands list so I don't know how to completely use it properly. Also I can't figure out how to make the arrows do damage, this is what I have so far.

// NPC made by E-Man
if (created) {
setimg woodenbow.png;
}
if (playertouchsme) {
toweapons Wooden Bow;
}
if (weaponfired && playerdir=0) {
freezeplayer 0.6;
setani shoot,woodenbow1.png;
sleep 0.2;
shoot playerx-0.8,playery+0.5,2,pi/2,0,0,eman_woodenarrow,;
}
if(weaponfired && playerdir=1){
freezeplayer 0.6;
setani shoot,woodenbow1.png;
sleep 0.2;
shoot playerx-1,playery+2,2,pi,1,0,eman_woodenarrow,;
}
if(weaponfired && playerdir=2){
freezeplayer 0.6;
setani shoot,woodenbow1.png;
sleep 0.2;
shoot playerx+0.2,playery+3,2,1.5*pi,.5,0,eman_woodenarr ow,;
}
if(weaponfired && playerdir=3){
freezeplayer 0.6;
setani shoot,woodenbow1.png;
sleep 0.2;
shoot playerx+1.3,playery+2,2,pi*2,1,0,eman_woodenarrow, ;
}



Also for some reason when I shoot left the arrow is transparent, I think that may be because of the shoot command though.
