Hi guys, I almost finished my new weapon xm1014 but the problem is that the weapon launch backward bullets wich hits me and makes a flying glitch. I did not read tutorials because I'm not english and could not understand.

-- Projectile: Bullet

You may not post that, thats useless imo.
i am not good scripter, but i think something wrong maybe here:

id=createprojectile(cc.xm1014.bullet.id)
projectiles[id]={}
rot=getplayerrotation(0)+(i*5)

and try put less recoil (actually, dont sure about this)

Nemesis has written

I already fixed this the error was in:
projectiles[id].sx=math.sin(math.rad(rot))*25.0
projectiles[id].sy=-math.cos(math.rad(rot))*25.0
I changed 25.0 into 15.0 and it worked to me.
You can test my script, and please tell me how to make images.

The problem is
projectiles[id]={}
should be
projectiles={}
