Hi Everybody,

So I have a Turret on my Tank(3d) and would like to aim it via a 2D Sprite...or a 3D Sprite and have the Turret move up/down reflecting the mouse movement.

Any ideas? I searched but cannot find anything on this, so if it's in the code archs someone got a link ?

thanx :)

Can't you just adjust the pitch of the turret based on the y-coordinate of the mouse cursor?

Eg

Graphics 800,600,0,2


MaxPitch# = 45.0 ; limit the angle to a maximum of +- 45 degrees as an example


Repeat
Pitch# = MaxPitch# * Float(MouseY() - (GraphicsHeight() / 2)) / (GraphicsHeight() / 2)
Cls
Text 0,0,Pitch
Flip
Until KeyDown(1)

Take a look and see how Tiny Tanks does it.
