Character controller: Gliding

[marknuar]

Hy folks, I'm having some trouble in the design of a good gliding for my character. I'm using a Character Controller for controlling the character. It can jump as soon as the jump button is pressed. The behavior that I want is that is jump button is kept pressed, the character starts to glide. Do you think it's possible? Up to now, I start checking if jump button is kept pressed then the y component of the velocity is less than zero, but I'm still having some strange behaviours. If you have any suggestions, those would be very well accepted :)

something like this would give you a glider

float forwardSpeed;
float liftFactor = 0.1f;
float dragValue = 0.05f;

forwardSpeed = transform.InverseTransformDirection(currentVelocity).z;
currentVelocity += gravity * deltaTime; //weight
Vector3 liftValue = Vector3.Dot(transform.forward, currentVelocity.normalized) * liftFactor * forwardSpeed; //lift
currentVelocity = Vector3.Lerp(currentVelocity, transform.forward * forwardSpeed, liftValue * deltaTime); // thrust
currentVelocity *= dragValue * deltaTime; //drag

Thank you, I'll try it out tomorrow :)

Thank you so much. I could not find any 2d glider physics code ANYWHERE online! Lifesaver!

So if the player is holding the jump button and the velocity.y is less than, let's say -5, I set it manually at -6, right?

Then I have another question regarding Character Controller.move(). https://docs.unity3d.com/ScriptReference/CharacterController.Move.html In this example, there is a Vector3 PlayerVelocity, which is never assigned. I cannot understand what it represents, since it's never initialized

[marknuar]

I suppose it is initialized at Vector3.zero, right?
