Function movement()
Local vel:vector3df = vector3df.create()
Local inertia:vector3df = vector3df.create()
Local m:matrix4 = New matrix4
vel = _vector3df(0,0,0)
inertia = _vector3df(0,0,0)
 
 
        If receiver.IsKeyDown(EKEY_KEY_W)
        vel = _vector3df(0,0,MOVEMENT_SPEED * frameDeltaTime))
        ElseIf receiver.IsKeyDown(EKEY_KEY_S)
        vel = _vector3df(0,0,-MOVEMENT_SPEED * frameDeltaTime)
        EndIf
 
        If receiver.IsKeyDown(EKEY_KEY_A)
        vel = _vector3df(-(MOVEMENT_SPEED * frameDeltaTime),0,0))
        ElseIf receiver.IsKeyDown(EKEY_KEY_D)
        vel = _vector3df((MOVEMENT_SPEED * frameDeltaTime),0,0))

        m= camera.getabsolutetransformation()   
        m.rotatevect(vel) 
        inertia.PlusEq(vel:vector3df)

greetings at the top, try updating the code to:

Local velo:vector3df = Vector3df.Create()

Movement into cameradirection

Hi!
Got a problem: i cant move into the direction of the camera.
ive searched irrlicht forums, but in this bmaxversion theys solutions wont work at all
what am i doing wrong?

Function movement()
Local nodePosition:Vector3df = camera.getPosition()
Local velo:vector3df

If receiver.IsKeyDown(EKEY_KEY_W)

velo.setZ(nodePosition.getZ() + (MOVEMENT_SPEED * frameDeltaTime))
ElseIf receiver.IsKeyDown(EKEY_KEY_S)
velo.setZ(nodePosition.getZ() - (MOVEMENT_SPEED * frameDeltaTime))
EndIf

If receiver.IsKeyDown(EKEY_KEY_A)
velo.setX(nodePosition.getX() - (MOVEMENT_SPEED * frameDeltaTime))
ElseIf receiver.IsKeyDown(EKEY_KEY_D)
velo.setX(nodePosition.getX() + (MOVEMENT_SPEED * frameDeltaTime))
EndIf

Local x:Float,y:Float,z:Float

Local m:matrix4 = New matrix4
m= camera.getabsolutetransformation()
m.rotatevect(velo)
X=camera.getposition().getX()+velo.getx()
Y=camera.getposition().getY()+velo.getY()
Z=camera.getposition().getZ()+velo.getZ()
camera.setposition(_VECTOR3dF(x,y,z))

End Function

get the error: unhandlet exception: attempt to access field or method of null object at "m.rotatevect(velo)"

hope anyone can help =/
