Hi, I'm afraid I have another problem/bug with my code, nothing too serious but it needs attention.

Problem - I have some car turning code. When I turn the car going forwards it's fine, and the same is with going backwards, the problem is when I travel forwards, turn, then I go backwards, when I turn, it will instantly rotate the car up to 180 degrees for some reason. Sorry if that didn't make much sense.

Increase Turning Variable Code -

+ Code Snippet

      If KeyState(32) = 1
         If KeyState(30) = 0
            If CarSpeed < 20 And CarSpeed > 0
               Inc RotationY,CarSpeed/CurCar.Turning
            Endif
            If CarSpeed > 20
               Inc RotationY,CarSpeed/(CurCar.Turning+2)
            Endif
            If CarSpeed < 0
               Dec RotationY,CarSpeed/CurCar.Turning
            Endif
         Endif
      Endif

Car Rotation Code -

+ Code Snippet

      If CarSpeed > 0
         YRotate Object CurCar.Number,WrapValue(RotationY)
      Endif
      If CarSpeed < 0
         YRotate Object CurCar.Number,WrapValue(-RotationY)
      Endif

EDIT - That was weird, I looked at my code when I posted it and realised that the -RotationY bit looked dodgy, do I removed the minus sign and it works now. Sorry about that guys, I do have another problem though with rotation, I'll use another post for it though.

Ok, here's yet another problem, probably quite easy to solve, but I don't get it.

Problem - My gun is attached to the firespot bone of the player, which of course is at the hands

. The problem is that it will not rotate accordingly to the firespot bone, just maintain the right position. The dummy object is just to point the firespot bone towards the target, I'm not sure if that is part of the problem or not.

Code -

+ Code Snippet

REM POSITION/ROTATE WEAPON
If WeaponStance = 1
   Position Object CurrentWeapon.Number,Limb Position X(PlrObj,PlrFirespot),Limb Position Y(PlrObj,PlrFirespot),Limb Position Z(PlrObj,PlrFirespot)
   Rotate Object CurrentWeapon.Number,Limb Angle X(PlrObj,PlrFirespot),Limb Angle Y(PlrObj,PlrFirespot),Limb Angle Z(PlrObj,PlrFirespot)
Endif

REM ROTATE LIMB TO CAMERA ANGLE
Position Object PlrFirespotDumObj,Limb Position X(PlrObj,PlrFirespot),Limb Position Y(PlrObj,PlrFirespot),Limb Position Z(PlrObj,PlrFirespot)
Point Object PlrFirespotDumObj,Object Position X(99999),Object Position Y(99999),Object Position Z(99999)
Rotate Limb PlrObj,PlrFirespot,Object Angle X(PlrFirespotDumObj),Object Angle Y(PlrFirespotDumObj),Object Angle Z(PlrFirespotDumObj)

Thanks a lot for any help guys. I appreciate these forums alot.

im a bit confused, are you saying that it doesn't rotate around the arm with the hand? Are you saying it doesn't rotate the right way?

Sorry I haven't answered this thread in a while, I haven't had the internet. I sorted the problem out, I just didn't realise that it won't rotate accordingly to the limb, I ended up just rotating it to the player object's y angle, worked perfectly.

Thanks anyway
