Inconsistent jumping with character controller
I've made a simple first person player controller script, which just moves the character so far. The X-Z movement is working fine, but I'm having trouble with an annoying glitchy effect that can happen when jumping. Normally jumping there is no problem. However if I jump to a higher level platform from a lower one, the jumping becomes inconsistent. Every second bounce is very low, much lower than programmed, while the ones in between are fine. This continues until I let go of the space bar, at which point it seems to reset itself and all works well until I jump up a level again. Note that this does not happen when jumping down a level. Here is the code:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Player : MonoBehaviour {
public float speed;
public float jumpSpeed;
public float resetSpeed;
public int health;
public float gravity;
Camera myCamera;
Vector3 myCameraOrigin;
Vector3 myCameraTarget;
bool justStopped = false;
float startTime;
float journeyLength;
public Vector3 currentVelocity;
// Use this for initialization
void Start () {
myCamera = GetComponentInChildren<Camera> ();
}
// Update is called once per frame
void Update () {
currentVelocity.x = 0;
currentVelocity.z = 0;
CharacterController con = GetComponent<CharacterController> ();
bool moving = false;
if (Mathf.Abs (Input.GetAxisRaw ("Forward")) > 0) {
moving = true;
currentVelocity += Vector3.forward;
}
if (Mathf.Abs (Input.GetAxisRaw ("Backward")) > 0) {
moving = true;
currentVelocity += Vector3.back;
}
if (Mathf.Abs (Input.GetAxisRaw ("Left")) > 0) {
moving = true;
currentVelocity += Vector3.left;
}
if (Mathf.Abs (Input.GetAxisRaw ("Right")) > 0) {
moving = true;
currentVelocity += Vector3.right;
}
if (Mathf.Abs (Input.GetAxisRaw ("Jump")) > 0 && con.isGrounded) {
currentVelocity.y += jumpSpeed * Time.deltaTime;
}
if (moving) {
float velocitySpeed = speed * Time.deltaTime;
Vector3 moveDirection = myCamera.transform.TransformDirection (currentVelocity);
moveDirection.y = 0;
moveDirection.Normalize ();
moveDirection *= velocitySpeed;
currentVelocity.x = moveDirection.x;
currentVelocity.z = moveDirection.z;
justStopped = false;
//myCamera.transform.Translate (Vector3.left * 0.01f * Mathf.Sin (Time.time * 5));
myCamera.transform.Translate (Vector3.up * 0.01f * Mathf.Sin (Time.time * 10));
}
if (!con.isGrounded) {
currentVelocity.y -= gravity * Time.deltaTime;
} else if (currentVelocity.y < 0) {
currentVelocity.y = 0;
}
con.Move (currentVelocity);
if (!moving && !justStopped) {
justStopped = true;
myCameraOrigin = myCamera.transform.localPosition;
myCameraTarget = new Vector3 (0, 1, 0);
startTime = Time.time;
journeyLength = Vector3.Distance(myCameraOrigin, myCameraTarget);
} else if (!moving) {
float distCovered = (Time.time - startTime) * resetSpeed;
float fracJourney = distCovered / journeyLength;
myCamera.transform.localPosition = Vector3.Lerp (myCamera.transform.localPosition, myCameraTarget, fracJourney);
}
transform.rotation = Quaternion.Euler (0, myCamera.transform.rotation.y, 0);
}
}

I solved the issue by moving the jump check to add jumping force after the isGrounded check, so that if a jump was initiated it is not immediately negated, as I think is what was happening.
