Unity C# - Rigidbody.AddForce not working as intended - c#

So, I am trying to make a cube move with the WSAD buttons and for some reason, even though I am not touching any buttons, it moves diagonally up and to the left. I am using Unity 4.5.1
Code:
using UnityEngine;
using System.Collections;
public class Movement : MonoBehaviour {
public float moveSpeed;
private Vector3 input;
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update () {
input = new Vector3(Input.GetAxis ("Horizontal"), 0, Input.GetAxis ("Vertical"));
print(input);
}
}

Your problem may be somewhere else, because the code seems just fine. If I were you, I'd try to take a look to this page. You might find the solution to this issue

Make the CC Collider follow the camera (UNITY)

So I made a script that should In theory make the Character Controller's Collider follow the Player camera. Here is the Script:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.XR;
public class CCCameraFollower : MonoBehaviour
{
public GameObject Camera;
public CharacterController character;
// Start is called before the first frame update
void Start()
{
character = GetComponent<CharacterController>();
}
// Update is called once per frame
void LateUpdate()
{
character.center = Camera.transform.position;
}
}
This works Fine/Okay when I try it out, however as soon as I enter Climb() In my Climber script:
void Climb()
{
InputDevices.GetDeviceAtXRNode(climbingHand.controllerNode)
.TryGetFeatureValue(CommonUsages.deviceVelocity, out Vector3 velocity);
character.Move(transform.rotation * -velocity * Time.fixedDeltaTime);
cachedVelocity = -velocity;
Debug.Log(cachedVelocity);
}
When this is Climb() Runs, this happens:
Image that Shows The Issue
I don't see a reason for this to happen, maybe its very obvious. I don't know... Anyways, my question is: "How do I make the Collider of the CC Follow the Player Camera?".
In the CCCameraFollower.LateUpdate() method you are actually moving the center of the character controller and not the position of the Camera. Change to this and it will probably work as you want.
void LateUpdate()
{
Camera.transform.position = character.center;
}

How To Add Mobile Touch Controllers In Unity

I am working on a game, and till now, i have allowed a user to play the game by moving up and down using the up and down arrow keys on the computer keyboard.
But now i want to make the user be able to do that on a mobile phone by touching up or down, or maybe swiping up or down to move in the game.
I am using c# for this.
This is the current code assigned to the player object:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Player : MonoBehaviour
{
public float playerSpeed;
private Rigidbody2D rb;
private Vector2 playerDirection;
// Start is called before the first frame update
void Start()
{
rb = GetComponent<Rigidbody2D>();
}
// Update is called once per frame
void Update()
{
float directionY = Input.GetAxisRaw("Vertical");
playerDirection = new Vector2(0, directionY).normalized;
}
void FixedUpdate()
{
rb.velocity = new Vector2(0, playerDirection.y * playerSpeed);
}
}
What do i need to do to achieve this?
You should try to make buttons with trasparency
You have plenty of possibilities here !
But there might have better solutions than others ;)
You could make a UI representing up and down arrow that respond with wathever behaviour you'd like when pressed ORyou could dig a little the Input documentation, espacially what's relative to touches.
From there you can get touch position in screen space an make whatever you want with it !
The choice is lead by the type of game or application you're trying to make. Hope that helped ;)

transform.position not setting correct position in Unity?

I am having this problem that I don't know how to solve, I have a moving object that return to a position if a condition is verified, but it seems like it is working sometimes, but sometimes it is not ..
Here is my script :
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class MovingDes : MonoBehaviour {
private float speed = 5f;
Transform trn;
//-37.6914
//62.32123
// Use this for initialization
void Start() {
trn = GetComponent<Transform>();
}
// Update is called once per frame
void Update() {
transform.Translate(Vector3.back * (speed * Time.deltaTime));
if(transform.position.z <= -37.6914){
Vector3 newPosition = new Vector3(17.5f,125.7f,165.32123f);
trn.position = newPosition;
}
}
}
The problem is that I can see in my Unity editor that the position is different from what I have set, and I don't understand from Where those values came from, I did not write them for sure.
Any help would be much appreciated.
You are moving object with transform.Translate every frame, so immediately after setting up new position, your object is moved again. Notice that in your case trn, and transform, refers to the same Transform component.
Why don't you change your trn.position= to transform.position= I don't think you need GetComponent<> for transform component of the current gameObject. Or maybe related to relativeTo parameter of .Translate method.

VR Adding Locomotion: Walk

Using Unity2017.3.1f1 Personal (64 bit) to build a VR app for Android, using Cardboard VR SDK. The purpose of the app is to allow users visualize data in an immersive way.
Currently want to do something similar to the scene view where one can move forward by going where one's looking but with the Cardboard single button i'm just gonna give the ability to move forward.
Built a Canvas where user can select what type of locomotion he/she wants: teleport or walk.
The teleport works fine as you can see here.
When the user selects walk, the following error shows in the Console:
NullReferenceException: Object
reference not set to an instance of an
object
Player.TryWalk () (atAssets/Player.cs:44)
Player.Update () (at Assets/Player.cs:37)
My Player script:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public enum InputMode
{
NONE,
TELEPORT,
WALK
}
public class Player : MonoBehaviour {
public static Player instance; //Singleton design pattern: only one instance of the class appears
public InputMode activeMode = InputMode.NONE;
[SerializeField]
private float playerSpeed = 3.0f;
void Awake()
{
if(instance != null)
{
GameObject.Destroy(instance.gameObject);
}
instance = this;
}
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update ()
{
TryWalk();
}
public void TryWalk()
{
if(Input.GetMouseButton(0) && activeMode == InputMode.WALK)
{
Vector3 forward = Camera.main.transform.forward;
Vector3 newPosition = transform.position + forward * Time.deltaTime * playerSpeed;
transform.position = newPosition;
}
}
}
The Player script was added as component of Player:
When the button Walk is pressed, the Active Mode changes to WALK, as you can see in the next image.
Still, even though this happens, the user is not able to Walk.
What can I do to solve this?
Camera.main; was returning null.
In order to fix it, had to have the camera in my scene tagged MainCamera as you can see in the next image.
See it working here.

Sprite movement In Unity 5

I recently started messing with the Unity 5 Scripting API and I can't seem to make this piece of code work for my Simple Smiley Face Sprite1. All I want it to do is move slightly. I have tried multiple solutions. I believe it is not accepting the key board button or it is not finding the sprite. Thank you for the help in advance!
...Super simple code, I am just experimenting.
using UnityEngine;
using System.Collections;
public class NewBehaviourScript : MonoBehaviour {
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update () {
if (Input.GetKey ("q")) {
var Sprite1 = GameObject.Find("Sprite1");
Sprite1.transform.Translate(1,3,5);
}
}
}
try using KeyCode.Q:
if(Input.GetKeyDown(KeyCode.Q))
{
var Sprite1 = GameObject.Find("Sprite1");
Sprite1.transform.Translate(1,3,5);
}
if (Input.GetKeyDown(KeyCode.Space))
{
Vector3 forward = transform.TransformDirection (Vector3.forward) * 10;
}
you can simply add this code to your sprite and change the number 10 or any other the speed you want
