Weapons
152- With our variables in place, we can now move onto the weapon's functionality. The
InstantFireStartTrace() function is the same function we added in our weapon
during our Chapter 3, Scripting a Camera System. It allows our weapon to start its trace
from the correct location using the GetPhysicalFireStartLoc() function.
As mentioned before, this simply grabs the rotation of the weapon's muzzle flash
socket, and tells the weapon to fire projectiles from that location, using the socket's
rotation. The same goes for GetEffectLocation(), which is where our muzzle
flash will occur.
The v in vector for the InstantFireStartTrace() function is not
capitalized. The reason being that vector is actually of struct type,
and not a function, and that is standard procedure in UDK./********************************************************
* Overriden to use GetPhysicalFireStartLoc() instead of
* Instigator.GetWeaponStartTraceLocation()

simulated function vector InstantFireStartTrace()
{
return GetPhysicalFireStartLoc();
}/********************************************************

fire on

which a cast to type TutPawn can fail */
