How to enter and exit from a vehicle

On this page, you will learn how to setup the enter-exit vehicle system.

Any vehicle can be controlled by the player, basically the entry system will disable the character controls and enable the vehicle control.

How vehicle detection works ?

Vehicles must have a child trigger with a specific tag and layer, the trigger must have a JU Vehicle Interactable to work.

The Player needs to have a JU Interaction System, which will detect the vehicle's trigger.

Characters without driver animations

For simple games you can disable the character instead of use complex animations and IK system.

Simple Character Driver Animation

If you have a character animation that match with the vehicle model you can use the JUVehicleCharacterIK to set the character position inside the vehicle.

Advanced Character Driver Animations with IK

You can use foot and hand IK on vehicles if you want, very useful to make wheel steer, motorcycle inclination animation or foot placements.

To use it, the character must have the DriverProceduralAnimation component, it's is responsible by the IK system.

Furthermore, you need to have assigned all the IK target positions on the JUVehicleCharacterIK of the vehicle and the IK weights configured.

Tip: if you see a prefab of a vehicle you will notice hand, foot, sphere or humanoid character gizmos. You can copy these GameObjects, paste them into your new vehicle, position them and assign them to the above parameters.
