Truck Town

This is a demo implementing different types of trucks of varying complexity using vehicle physics.

Controls:

  • Up Arrow, W, Gamepad Right Trigger, Gamepad A/Cross: Accelerate
  • Down Arrow, S, Gamepad Left Trigger, Gamepad B/Circle, Gamepad X/Square: Brake/reverse
  • Left Arrow, Gamepad Left Stick, Gamepad D-Pad Left: Steer left
  • Right Arrow, Gamepad Left Stick, Gamepad D-Pad Right: Steer right
  • U, Gamepad Select, left-click speedometer: Change speedometer unit (m/s, km/h, mph)
  • C, Gamepad Y/Triangle: Change camera (exterior, interior, top-down)
  • Escape, Gamepad D-Pad Up: Go back to menu (press again to exit)

On mobile platforms, the vehicle automatically accelerates. Touch the left and right edges of the screen to steer. Touch the middle of the screen to brake/reverse (this also temporarily stops acceleration).

Language: GDScript

Renderer: Forward+

How does it work?

The base vehicle uses a VehicleBody3D node. The trailer truck is tied together using a ConeJointTwist node, and the tow truck is tried together using a chain made of RigidBody3D nodes which are pinned together using PinJoint nodes.
