If you'd like to change where Shawn's arrow spawns, or any other projectile, you'll find the data for it in globalDat (id=142). Find the PtWithName of the projectile (10 for Shawn's arrow, standing) and change the velocity attributes (vx, vy and vz).

vz will cause the arrow to go up with negative values, and down with positive values. Default is 0 so it goes straight.
vy will cause the arrow to go higher with negative values, and lower with positive values.
vx is what you want, lower values will cause the arrow to not go as far, but they will also hit the opponent that is touching you.

This will also change the velocity of the arrow though. This is the solution @S*LuEX told me. Don't know any other right now.
