au3irrlicht - moving a scene node

[aNewLyfe]

Hi, after 2 days i've gave up.

Problem is: i want to move a node forward by a keypress for example W. Well, moving on x+, x- or z+, z- is done. But i want to move node to forward. (Where it looking, facing at)

variables i got: node rotation, node speed, node x,y,z points.

Tried something like:

$NODE_X += (cos(($PI/360)*($NODE_YROTATION+90))*$MOVE_SPEED)

$NODE_Z += (cos(($PI/360)*($NODE_YROTATION+90))*$MOVE_SPEED)

bad idea? my math is FF btw.

Really waiting 4 your help.

you can create additional nodes (front, back left and right) that are too small to see. make them child nodes of the main node and when you movement key _ispressed() then set the main node position to the position of the front (back left or right) node

$dll = DllOpen("user32.dll")
If _IsPressed("57", $dll) Then;w
            $posf = _IrrGetNodeAbsolutePosition($FrontNode)
            _IrrSetNodePosition($node, $posf[0], $Pos[1], $posf[2])
        ElseIf _IsPressed("53", $dll) Then;s
            $posb = _IrrGetNodeAbsolutePosition($BackNode)
            _IrrSetNodePosition($node, $posb[0], $Pos[1], $posb[2])
        EndIf

well tnx 4 reply and your time.

But i've found the formula after 3 days

((Cos(direction degree * pi number / 180) * node movement speed))
