Im trying to make a targeting laser for my space game. The problem is, when you rotate the ship, the beam moves away from the ship so that it is floating next to it. You'll have to try my code to understand.

arrow keys move.
Keypad Enter uses the Targeting laser.

Am I an Idiot...or is everyone else just really smart?

I found this code somewhere on the forum maybe you can use it...
I had no time to test it yet but i think it works

I know the point object command is a little like (...), it
sometimes turns to the wrong point.... it sucks

REM Usage : pointturret(SourceObject,SourceLimb,Object to track)

function pointturret(Osource,Lsource,Otrack)

REM Deltas
DeltaY# =(object position Y(Otrack)- limb position Y(Osource,Lsource))

REM distance between objects (2d)
distance# = sqrt(((deltaX#)*(deltaX#))+((deltaZ#)*(deltaZ#)))

REM Angles
Yangle# = wrapvalue(Atanfull(DeltaX#,DeltaZ#)+180)
angle# = wrapvalue(Atanfull(deltaY#,abs(distance#)))

set object rotation zyx Osource
REM Point
Rotate limb Osource,Lsource,angle#,Yangle#,0
