I try to accomplish smooth movement with the Xbox Controller, however it is very snappy, even though snap is turned of and deadzone set to 0. Movement with keyboard however is very smooth, so I assume GetAxis does not work with a controller, it's always GetAxisRaw. So I switched to GetAxisRaw and tried to smooth everything out. Even with acceleration, the movement is still very jagged and snappy. Does anyone have an idea how to get a nice smooth movement with a controller, like keyboard + GetAxis?
public class PlayerController : MonoBehaviour
{
CharacterController cc;
float acceleration = 0;
[SerializeField] float speed;
[SerializeField] float acclerationRate = 1;
private void Awake()
{
cc = GetComponent<CharacterController>();
}
private void Update()
{
float deadzone = 0f;
Vector2 stickInput = new Vector2(Input.GetAxisRaw("Horizontal"), Input.GetAxisRaw("Vertical"));
if (stickInput.magnitude < deadzone)
stickInput = Vector2.zero;
else
stickInput = stickInput.normalized * ((stickInput.magnitude - deadzone) / (1 - deadzone));
if (stickInput.x != 0 || stickInput.y != 0)
{
acceleration += Time.deltaTime * acclerationRate;
acceleration = Mathf.Clamp01(acceleration);
}
else
{
acceleration = 0;
}
cc.Move(new Vector3(stickInput.x, 0, stickInput.y) * speed * acceleration * Time.deltaTime);
}
}
I would keep track of your player's velocity and use MoveTowards to adjust it based on the input. Don't forget to clamp your input's magnitude so your character doesn't travel diagonally faster than orthogonally in the event the player prefers keyboard input.
CharacterController cc;
[SerializeField] float speed;
[SerializeField] float acclerationRate = 1;
[SerializeField] float deadzone = 0f;
Vector3 velocity;
private void Awake()
{
cc = GetComponent<CharacterController>();
velocity = Vector3.zero;
}
private void Update()
{
Vector3 stickInput = new Vector3(Input.GetAxisRaw("Horizontal"), 0f,
Input.GetAxisRaw("Vertical"));
if (stickInput.magnitude < deadzone)
}
stickInput = Vector3.zero;
}
else
{
float clampedMag = Mathf.Min(1f, stickInput.magnitude);
stickInput = stickInput.normalized * (clampedMag - deadzone) / (1f - deadzone);
}
velocity = Vector3.MoveTowards(velocity, stickInput,
accelerationRate * Time.deltaTime);
cc.Move(velocity * Time.deltaTime);
}

I have this script below and I want my player to always move towards the rotation angle, which doesn't happen. It only changes direction when I click.
My purpose is for the player to move at all times and towards the rotation which should be controlled by mouse position/mouse x axis (kind of like auto-run, but always change rotation based on mouse, not just move right or left).
I've tried about 10 different methods, nothing worked so far...
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class MovementController : MonoBehaviour
{
public float speed = 4;
public float rot = 0f;
public float rotSpeed = 80;
public float gravity = 8;
private Camera cam;
Vector3 moveDir = Vector3.zero;
CharacterController controller;
Animator anim;
// Start is called before the first frame update
void Start()
{
controller = GetComponent<CharacterController> ();
anim = GetComponent<Animator>();
}
// Update is called once per frame
void Update()
{
float horizontalSpeed = 8.0f;
//Get the mouse delta. This is not in the range -1...1
float h = horizontalSpeed * Input.GetAxis("Mouse X");
float z = horizontalSpeed * Input.GetAxis("Mouse Y");
transform.Rotate(0, h, 0);
//Move Input
if(controller.isGrounded){
if(Input.GetMouseButtonUp(1))
{
anim.SetInteger ("condition", 1);
moveDir = new Vector3 (0,0,1) * speed;
// moveDir *= speed;
moveDir = transform.TransformDirection(moveDir);
}
if(Input.GetMouseButtonDown(1))
{
anim.SetInteger("condition", 0);
moveDir = Vector3.zero;
}
}
moveDir.y -= gravity * Time.deltaTime;
controller.Move(moveDir * Time.deltaTime);
}
}
Transform.LookAt
Just get a cursor position and that's it
Vector3 direction = target.position - player.transform.position;
Quaternion finalPlayerRotation = Quaternion.LookRotation(direction);
player.transform.rotation = finalPlayerRotation;
This also works in some cases:
Vector3 direction = target.position - player.transform.position;
player.transform.right /*You may need to change the Right to upper, -upper, -Right depend on the player rotation and the target position*/ = direction;
Im having a lot of weird prolems with my rigidbody collision in unity. I have a player controller script which allows me to move my player, but when it collides with stairs, it glitches out. when it collides with a door, it glitches out and when it collides with 2 nvisible box colliders at the edge of the map while walking diagonally, it walks through one of them. Ive searched around quite a bit but couldn't find anything. I know it's not a lot to go on, but here is some stuff that might help:

A screenshot of my player object's important components:
P.S. the code has some weird gravty changing parts. Thats for the rest of the game, but it's not important for this question. Hopefully you guys can help me. Im happy to provide any other information you might need :) thanks for your time in advance!!
Edit: Commented out one part based on the first answer, but that din't fix it
First of all, you move your player 'twice', first inside movePlayer function you have:
//move the player
if (inputs != Vector3.zero){
body.velocity = inputs;
}
and then in every FixedUpdate:
body.MovePosition(body.position + inputs * speed * Time.fixedDeltaTime);
body.MovePosition moves yours player, but not zeroes velocity (which you set in movePlayer function).
By moving player this way you can 'overshoot' too small colider, so object will pass through.
You can add more drag to rigidbody to slowdown object a bit.
Okay so for anyone having similar problems, I found the answer:
The problem was that I was using body.moveposition, this should actually body.addforce.
This oes mean that you have to change some of the code. If you want further explanation because you had a similar problem, contact me, but here is my improved code to get you started:

public int direction = 1;
public void movePlayer(Vector2 movement){
float horizontal = movement.x;

//check if the player is standing on the ground

}

}

Quaternion.AngleAxis(0f, Vector3.forward) *
Quaternion.AngleAxis(targetAngle, Vector3.up);
}
else{
direction = 1;
}
//rotate the player in the move direction as long as they are moving
if (inputs.magnitude >= 0.1f){
transform.rotation = rotation;
}
}
void FixedUpdate(){
body.AddForce(inputs * speed * Time.fixedDeltaTime);
}
public void flip(int changedDirection){
inputs = Vector3.zero;
angle = 0f;
targetAngle = 0f;
direction = changedDirection;
}
public void walk(){
if (isGrounded){
speed = walkSpeed;
}
}
public void run(){
if (isGrounded){
speed = runSpeed;
}
}
public void jump(){
if (isGrounded){
if (direction == 1){
body.AddForce(new Vector3(0, jumpHeight, 0));
}
else if (direction == 2){
body.AddForce(new Vector3(jumpHeight, 0, 0));
}
else if (direction == 3){
body.AddForce(new Vector3(0,0 , jumpHeight));
}
}
}
}
For me this created some additionl problems with jump for example, so here are the values you need to tweak to fix those: the rigidbody mass and drag and the player controller gravity and jump height.
The grounded state for my character controller flickers on and off constantly at what seems to be every frame. From what I know, it's supposed to check if the player is grounded through player.isGrounded, but something else is moving it back up.

It looks like it has to do with the verticalVelocity lines, but so far I have only tried setting verticalVelocity = 0 and that works until I have actually moved the character. What could I change to stop the flickering?
Probably it is already solved, but the reason for that is that if you are using Character Controller you should apply gravity ALL the time to the character.
When the character collides with a object, it actually enters a little bit inside this object, then Unity pushes the character back away from the object, until it is no longer touching it. At this point, your gravity starts acting again, and re initiziling the cycle.
You need to apply gravity 100% of the time to create enough force to "balance" this fight with the floor. Could be a smaller "gravity" like 1. No need to be your gravity variable.
Also, on top of that, I like to add a "Coyote time", and make my on IsGrounded() method, as follows:
public bool IsGrounded()
{
return CoyoteTime < CoyoteTimeMax;
}
public void CoyoteControl()
{
if (CharController.isGrounded)
{
CoyoteTime = 0;
}
else
{
CoyoteTime += Time.deltaTime;
}
}
And then I call the CoyoteControl() on Update(), and I can call IsGrounded() whenever I need.
On the inspector I usually set the CoyoteTimeMax to 0.1 and it makes falls more smooth.
As per you comment. You should not determine if your player is grounded by checking an animation parameter. The best way is to use a RayCast(). So what you have to do:
Create a Layer named Ground, and add all the platforms in your
scene to that layer.
Create a bool variable
i.e
bool isGrounded;
Create a function to check if the character is grounded
Something like:
bool checkGrounded(){
return Physics.Raycast(transform.position, Vector3.down, 2f, 1 << LayerMask.NameToLayer("Ground")));
}
In this answer you can read about the involved parameters in the Raycast
Finally inside the update check if the player is grounded or not
Something like:
void Update(){
isGrounded = checkGrounded();
}
I have found that the isGrounded check can change over the course of the Update() function if you are checking it multiple times. Assigning it to a variable at the beginning of the function may solve the flickering issue.
void Update()
{
bool isGrounded = characterController.isGrounded;
...
void Update ()
{
Vector3 input = new Vector3 (0, 0, 1);
Vector3 direction = input.normalized;
Vector3 velocity = direction * speed;
Vector3 moveAmount = velocity * Time.deltaTime;
transform.position += moveAmount;
if(Input.GetKeyDown(KeyCode.Space) && isGrounded)
{
player.AddForce (Vector3.up * jumpForce, ForceMode.Impulse);
}
}
Since Time.deltaTime varies moveAmount also varies for every jump making the distance of the jump vary slightly.
The ball is to jump between blocks separated by a fixed gap and therefore the above behaviour causes problems.
Is there any way I can fix this and make fixed length jumps?
You can use CharacterController for this. Make sure you have a CharacterController and Collider attached to your gameobject. Also if you have a rigibody attached to your game object it may cause it to behave unexpectedly so you might have to contraint it.
public CharacterController controller;
private float verticalVelocity;
private float gravity = 25.0f;
private float jumpForce = 15.0f;
void Awake () {
controller = GetComponent<CharacterController>();
}
void Update () {
if( controller == null )
return;
if( controller.isGrounded)
{
verticalVelocity = -gravity * Time.deltaTime;
if( Input.GetKeyDown(KeyCode.Space) )
{
verticalVelocity = jumpForce;
}
}
else
{
verticalVelocity -= gravity * Time.deltaTime;
}
float moveHorizontal = Input.GetAxis ("Horizontal");
float moveVertical = Input.GetAxis ("Vertical");
Vector3 moveVector = Vector3.zero;
moveVector.x = moveHorizontal * 5.0f;
moveVector.y = verticalVelocity;
moveVector.z = moveVertical * 5.0f;
controller.Move(moveVector * Time.deltaTime);
}
