#4 Sorry about he long pos also anyone wanna gimme some pointers on normal grenade behavior that'd be awsome

#5 Join the www.gamebeavers.org site, and gain access to 2 types of grenade launchers, both working excellently.

#6 I know this is a really old post but I will point out the problem anyway. A lot of people miss this little detail and causes them all kinds of grief.

Based on the code above the image name for onFire should be GrenadeLauncherImage. 
Thats why it will not fire. Change RocketLauncherImage to GrenadeLauncherImage and it should work.

function RocketLauncherImage::onFire( %this, %obj, %slot )
{
%projectile = %this.projectile;
%muzzleVector = %obj.getMuzzleVector( %slot );
%objectVelocity = %obj.getVelocity();
%muzzleVelocity = VectorAdd( VectorScale(%muzzleVector, %projectile.muzzleVelocity),
VectorScale(%objectVelocity, %projectile.velInheritFactor) );
%p = new (%this.projectileType)()
{
dataBlock = %projectile;
initialVelocity = %muzzleVelocity;
initialPosition = %obj.getMuzzlePoint(%slot);
sourceObject = %obj;
sourceSlot = %slot;
client = %obj.client;
};
MissionCleanup.add( %p );
return %p;
}
