VehicleBody - How to control it when it's jumping?

javzero

Hi all!. I made a car using VehicleBody. When you make it jump down a ramp you lose control while it is in the air. I'm trying to build a mechanic that allows you to rotate it a bit in the air to land in a better way. (Like GTA and those kind of games)

I partialy achieve this by checking if the car is not grounded and if so you can rotate it with the same control keys. (WASD)

I am using something like this: (If car is in air):

if Input.is_action_pressed("Forward"): angular_velocity.x = -1 if Input.is_action_pressed("Reverse"): angular_velocity.x = 1 if Input.is_action_pressed("Left"): angular_velocity.z = 2 if Input.is_action_pressed("Right"): angular_velocity.z = -2

The problems is that my car rotates relative to world or relative to axis (I dont know). When you jump towards the X axis (or lets say North) and hit "Forward key" you can control pitch. But when you jump towards the Y axis (or lets say East) and hit "Forward Key" you can control rol.

I want to control allways pitch with forward and backwards key and rol with left and right. How can I manage to do that?

Maybe my explanations is a little confusing (Im not an english speaker). Let me know if more info is needed.

Thanks!

I think you could make use of 3D transforms and some vector tricks with the basis to achieve that.

If I modify the transform of the car it looses speed in the air (kind of slowmotion effect). That's why I'm trying to use something like add force or apply velocity. But I can't find how to apply forces relative to vehicle orientation. I mean, I cant't find the right implementation in the docs.

There's an apply_torque method which probably also applies to VehicleBody (via RigidBody). Or you use two times apply_impulse (think of two fingers on a fidget spinner).

Here's an answer in the q&a which still uses apply_impulse but mentions apply_torque: https://godotengine.org/qa/35714/how-to-i-apply-torque-to-a-rigidbody-3d

Perhaps that helps?
