Is it possible to move a gameobject to click position in unity 2D while gameobject is a rigidbody 2d with gravity and movement looks like jump from gameobject's position to click position. Any help reference will be really helpful :)
something a bit like this?
Transform projectile;
float speed = 5f;
void Update()
{
if(Input.GetMouseButtonDown(0))
{
Vector3 target = Camera.main.ScreenToWorldPoint(Input.mousePosition);
target.z = projectile.position.z;
Vector3 offset = target - projectile.position;
Vector3 direction = offset.normalized;
float power = offset.magnitude;
projectile.GetComponent<RigidBody2D>().AddForce(direction * power * speed);
}
}

I am creating a 2d mobile game where one of the scripts uses a joystick to move and the other script lets the player shoot an object when tapping anywhere on the screen. The issue is when using the joystick it also shoots at the same time in that direction. Is there a way to separate the touches so when you use the joystick it does not immediately shoot to that direction but the player can still move and shoot anywhere at the same time?
Move Code
private void Update()
{
Vector2 moveInput = new Vector2(joystick.Horizontal, joystick.Vertical);
moveAmount = moveInput.normalized * speed;
}
Shoot code
private void Update()
{
Vector2 direction = Camera.main.ScreenToWorldPoint(Input.mousePosition) - transform.position;
float angle = Mathf.Atan2(direction.y, direction.x) * Mathf.Rad2Deg;
Quaternion rotation = Quaternion.AngleAxis(angle - 90, Vector3.forward);
transform.rotation = rotation;
if(Input.GetMouseButton(0))
{
if (Time.time >= shotTime)
{
Instantiate(projectile, shotPoint.position, transform.rotation);
shotTime = Time.time + timeBetweenShots;
}
}
}
Instead of using Input.mousePosition you'll have to use Input.GetTouch. You can loop through it using Input.touchCount to find the first touch that is not interacting with a ui element, than use that touch instead of Input.mousePosition to find the direction to shoot (or not shoot if there is no touch). To find out if a specific touch is over ui you need a reference to the scene's EventSystem (or use EventSystem.current), and use EventSystem.IsPointerOverGameObject with Touch.fingerId.
If the joystick is not a ui element you'll need a different way to detect if the touch is over the joystick. For example you could check the pixel position, or see if the joystick itself has an "interacting fingerId". But with the assumption that the joystick is an ui element, here's one way to do what I wrote above: (untested)
private void Update()
{
var eventSystem = EventSystem.current;
for (var i = 0; i<Input.touchCount; i++)
{
var touch = Input.GetTouch(i);
if (eventSystem.IsPointerOverGameObject(touch.fingerId))
{
continue;
}
ShootToScreenPos(Vector2 screenPos);
break;
}
}
private void ShootToScreenPos(Vector2 screenPos)
{
Vector2 direction = Camera.main.ScreenToWorldPoint(screenPos) - transform.position;
float angle = Mathf.Atan2(direction.y, direction.x) * Mathf.Rad2Deg;
Quaternion rotation = Quaternion.AngleAxis(angle - 90, Vector3.forward);
transform.rotation = rotation;
if (Time.time >= shotTime)
{
Instantiate(projectile, shotPoint.position, transform.rotation);
shotTime = Time.time + timeBetweenShots;
}
}
I am making a 360 camera movement for my game called PROTOTYPE. I need a function or something to detect if the mouse is moving and in which direction on the x axis it is, to set an offset for the Camera Smoothing script, but I don't know any. Could somebody plz help me? Here is the Camera Smoothing script if u need it:
using UnityEngine;
public class CameraFollow : MonoBehaviour
{
public Transform target;
public float smoothSpeed = 0.125f;
public Vector3 offset;
void FixedUpdate()
{
Vector3 desiredPosition = target.position + offset;
Vector3 smoothedPosition = Vector3.Lerp(transform.position, desiredPosition, smoothSpeed);
transform.position = smoothedPosition;
transform.LookAt(target);
}
}
I suppose you want to move your camera with your mouse, 360° around your character and also that script is attached to your player.
In order to do that, your FixedUpdate should look like this:
void FixedUpdate()
{
float horizontalAxis = Input.GetAxis("Mouse X"); // Getting the current mouse axis (left-right)
float verticalAxis = Input.GetAxis("Mouse Y"); // Getting the current mouse axis (up-down)
transform.RotateAround(player.transform.position, -Vector3.up, horizontalAxis * smoothSpeed);
transform.RotateAround(Vector3.zero, transform.right, verticalAxis * smoothSpeed);
}
I want to move my player character(human) on a curved surface. But at the same time character shall stay perpendicular to the surface normals and it should face in the movement direction and can handle collisions(if there is a wall ahead, shall not be able to go through it).
I tried to make a parent stay over normals and change the child local rotation towards direction of motion of its parent. But it has several limitations as of now.
Here is the code what i was using:
[SerializeField] float raycastLength = 1f;
bool canPlayerMove = true;
public float speed = 2f;
public Vector3 offset; //object's position offset to ground / surface
public Quaternion childDirection;
private void Update()
{
float moveHorizontal = SimpleInput.GetAxis("Horizontal");
float moveVertical = SimpleInput.GetAxis("Vertical");
Ray ray = new Ray(transform.position, -transform.up);
RaycastHit hitInfo;
if (Physics.Raycast(ray, out hitInfo, raycastLength))
{
transform.rotation = Quaternion.LookRotation(Vector3.up, hitInfo.normal);
transform.position = hitInfo.point + offset;
Debug.DrawLine(ray.origin, hitInfo.point, Color.red);
}
if (canPlayerMove)
{
Vector3 movement = new Vector3(moveHorizontal, 0, moveVertical);
if (movement != Vector3.zero)
{
childDirection = Quaternion.Slerp(transform.GetChild(0).localRotation, Quaternion.LookRotation(movement), 0.15F);
transform.GetChild(0).localRotation = childDirection;
}
transform.Translate(movement * speed * Time.deltaTime, Space.Self);
}
}
first to not make your player go thru walls you want to add a collider to your walls and not set it as trigger, you will also need a rigidbody on your player and this will help in the next steps.
Secondly you will need to acces the rigidBody in code using this: (if you Check Use Gravity it will also stay on your terrain that you made)
private Rigidbody rb;
private float speed = 7.5f;
private void Start()
{
//this gets the rigidbody on the gameObject the script is currently on.
rb = this.GetComponent<Rigidbody>();
}
private void Update()
{
float hor = Input.GetAxis("Horizontal");
float vert = Input.GetAxis("Vertical");
//this will move your player frame independent.
rb.MovePosition(this.transform.position + new Vector3(hor, 0, vert) * speed *
Time.deltaTime);
}
Also make sure that you have a rigidBody on your player, else it will throw an error.
This is for a 2D platform game.
I don't want the camera to move up the Y axis when the player jumps. I only want it to move when the player to the upper part of the screen so it can scroll up to vertical platforms and ladders.
Does anybody know what to enter in the code and the Unity editor so that can be done?
Here's the code I have so far in the camera script.
public class CameraControl : MonoBehaviour {
public GameObject target;
public float followAhead;
public float smoothing;
private Vector3 targetPosition;
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update () {
targetPosition = new Vector3 (target.transform.position.x, transform.position.y, transform.position.z);
if (target.transform.localScale.x > 0f) {
targetPosition = new Vector3 (targetPosition.x + followAhead, targetPosition.y, targetPosition.z);
} else {
targetPosition = new Vector3 (targetPosition.x - followAhead, targetPosition.y, targetPosition.z);
}
transform.position = Vector3.Lerp (transform.position, targetPosition, smoothing * Time.deltaTime);
}
}
I guess you have a bool tied to the jump which triggers the jumping animation.
So, in the Update() of the camera you can do something like this:
void Update() {
// Update camera X position
if (isPlayerJumping) return;
// Update camera Y position
}
This way, you update the Y position of the camera only if the player isn't jumping, while still updating the X position in all cases (even while jumping).
I want to rotate camera around an fbx object when a key is being pressed using unity 3d.How it do? I tried some examples but its not working. First i create a game object and add main camera child of it.
public class CameraOrbit : MonoBehaviour
{
public Transform target;
public float speed = 1f;
private float distance;
private float currentAngle = 0;
void Start()
{
distance = (new Vector3(transform.position.x, 0, transform.position.z)).magnitude;
}
void Update()
{
currentAngle += Input.GetAxis("Horizontal") * speed * Time.deltaTime;
Quaternion q = Quaternion.Euler(0, currentAngle, 0);
Vector3 direction = q * Vector3.forward;
transform.position = target.position - direction * distance + new Vector3(0, transform.position.y, 0);
transform.LookAt(target.position);
}
}
I dont have access to unity at the moment so i might have messed something up.
The idea is keep an angle that you change based on input. Create a Quaternion from the angle (the Quaternion say how to rotate a vector to a certain direction), then rotate a Vector to that direction. Starting from the targets position move in that direction a certain distance and then look at the targets position.
This only implements rotation around the y axis, if you want rotation around the x axis all you need is another angle variable and then change to this Quaternion.Euler(currentAngleX, currentAngleY, 0);
