CharacerController not allowing mid-air movement

Questions & Answers
1

I am attempting to implement a 3rd person platformer. A key aspect of platforming is the ability to control your character while in the air. I took the code from the Unity documentation on CharacterController.Move and I noticed that if I took the movement part of the code out of the if(player.isGrounded) (so that the player could still move even if he was in the air), I couldn’t jump. I tried a lot of things (changing values, lerping positions, and lots more) but I couldn’t get the jumping working. Here’s the code:

using UnityEngine;
using System.Collections;

public enum State
{
	standing = 0,
	walking = 1,
	running = 2,
	sprinting = 3,
	jumping = 4
}

[RequireComponent (typeof(CharacterController))]
public class MovementController : MonoBehaviour
{
	public float walkSpeed = 3.0f;
	public float runSpeed = 4.0f;
	public float sprintSpeed = 6.0f
	public float strafeSpeed = 0.80f;

	public float runThreshold = 0.5f;
	public float maxSprintSeconds = 15.0f;
	public float sprintCooldown = 1.0f;
	public float sprintCooldownStart = 5.0f;

	public float jumpForce = 8.0f;
	public float airControl = 3.0f;
	public float gravity = 20.0f;

	private Vector3 moveDirection = Vector3.zero;
	private CharacterController player;
	private float horizontal;
            private float vertical;
            private State currentState = State.standing;

	public void Start ()
	{
		player = GetComponent<CharacterController> ();

		if (!player) {
			Debug.Log ("There is no CharacterController component attached to the \"" + gameObject.name +
				"\", and the MovementController.cs script depends on it!");
		}
	}

	public void Update ()
	{
		if (!player)
			return;

		horizontal = Input.GetAxis ("Horizontal");
		vertical = Input.GetAxis ("Vertical");

		if (player.isGrounded) {
			if (horizontal == 0 && vertical == 0)
				currentState = State.standing;
			else if (Mathf.Abs (horizontal) < runThreshold && Mathf.Abs (vertical) < runThreshold)
				currentState = State.walking;
			else if (Mathf.Abs (horizontal) > runThreshold || Mathf.Abs (vertical) > runThreshold)
				currentState = State.running;

			if (currentState == State.walking) {
				moveDirection.Set (horizontal * strafeSpeed * walkSpeed, 0, vertical * walkSpeed);
			}
			if (currentState == State.running) {
				moveDirection.Set (horizontal * strafeSpeed * runSpeed, 0, vertical * runSpeed);
			}

			if (Input.GetButton ("Jump"))
				moveDirection.y = jumpForce;
		} else {
			currentState = State.jumping;

			moveDirection.x = horizontal * strafeSpeed * airControl;
			moveDirection.y = vertical * airControl;
		}

		moveDirection = transform.TransformDirection (moveDirection);
		moveDirection.y -= gravity;
		moveDirection *= Time.deltaTime;

		player.Move (moveDirection);
	}

}

Thanks in advance, for helping me. :slight_smile:

Just wrap the IsGrounded only around the Jumpbutton-block.
