Does anyone know how to make the the next object slide to the right? What I want is after the right object disappear the next right object slide to the right and repeat. I try to do it, the right object disappear but the next right one not move to the right.

I wanted to make that when you swipe to the left you apply a left force and when you swipe to the right you apply a right force.
this is how I imagine the code would be:
private Vector2 direction;
void Update()
{
swipeDirection();
}
void FixedUpdate()
{
rb2D.AddForce(direction);
}
void swipeDirection()
{
if (swipe to the left)
{
direction = new Vector2(-10, 0);
}
else if (swipe to the right)
{
direction = new Vector2(10, 0);
}
}
I would try something like this:
using UnityEngine;
public class ApplyForceOnSwipe: MonoBehaviour {
Vector3 touchInitPos;
Vector3 touchEndPos;
bool applyForce = false;
Vector3 forceDir;
void Update() {
if (Input.GetTouch(0).phase == TouchPhase.Began) {
touchInitPos = Input.GetTouch(0).position;
}
if (Input.GetTouch(0).phase == TouchPhase.Ended) {
touchEndPos = Input.GetTouch(0).position;
forceDir = (touchEndPos - touchInitPos).normalized;
applyForce = true;
}
}
void FixedUpdate() {
if (applyForce) {
rb2D.AddForce(forceDir);
applyForce = false;
}
}
}
Used a boolean to avoid applying the force multiple times and apply it only once per swipe.
Not debuggued. Hope it might work or inspire you :)
Have tried a few things but they didn't seem to work, so I was hoping that you guys could help me.
I've trying to make this demo for a little time now, but I can't seem to get the jumping to work.
When I try to jump while running, I can't. But I can however jump forever when i get up in the air, which is something that I would like to remove from the game.

I am not sure why you are trying to control the gravity of the player when gravity is already applied to any gameObject with the RigidBody or RigidBody2D component attached to it. It is good that you are reading input in the Update() function and applying the motion inside of the FixedUpdate(). Here is a slight tweak to your current code, let me know how this goes.
Rigidbody2D rb2d;
public float moveVelocity = 8f;
public float jumpVelocity = 15f;
private float horizontalInput = 0.0f;
// did the player just try to jump
private bool justJumped = false;
void Start()
{
rb2d = GetComponent<Rigidbody2D>();
}
void Update()
{
// grab how the player is moving - this value is mapped to your arrow keys
// so horizontal is left / right arrow and Vertical is up/down arrow
// the value is between [-1, 1] respectively
horizontalInput = Input.GetAxis("Horizontal");
// player tried to jump, we are not currently jumping and the player is grounded
if(IsGrounded() && Input.GetKeyDown(KeyCode.UpArrow))
{
justJumped = true;
}
}
private void FixedUpdate()
{
// handle our jump
if(justJumped)
{
// we just applied a jump so do not apply it again
justJumped = false;
// you can either apply the jump by setting velocity, but I would recommend using AddForce instead
rb2d.AddForce(Vector2.up * jumpVelocity);
}
// we are moving in either the left or right direction
if(horizontalInput != 0)
{
// move in the horizontal axis, but keep our Y component of velocity the same in case we jumped
rb2d.velocity = new Vector2 (horizontalInput * moveVelocity, rigidBody.velocity.y);
}
else
{
// just in case we are not moving, assure this by setting the horizontal component of velocity to 0
rb2d.velocity = new Vector2 (0f, rigidBody.velocity.y);
}
}
// determines if this object is currently touching another object that is marked as ground
private bool IsGrounded() {
// our current position (the player)
Vector2 position = transform.position;
// the direction we are going to aim the raycast (down as that is where the ground is)
Vector2 direction = Vector2.down;
// the ground should be close, so check it very close to the player
float distance = 1.0f;
// check if we hit anything that is on the layer of just ground - ignore all other layers
// IMPORTANT:: Make sure to make a Layer and set all of your ground to this layer
RaycastHit2D hit = Physics2D.Raycast(position, direction, distance, LayerMask.GetMask("GroundLayer"));
// we hit a ground collider, so we are grounded
if (hit.collider != null) {
return true;
}
return false;
}
Let me know if this works for you. I changed a few things around such as using GetAxis() instead of using the arrow keys as in Unity, these are the same. I also changed your jump to use an AddForce2D instead of setting velocity. The one addition was I added a IsGrounded() which will detect if whatever object this script is on (I assume it is on your player object) is near or touching objects below them that are marked as GroundLayer. If you have questions comment below.
I am creating a build in Unity 2019.4.12f1 and need to drag an object with Right Mouse button.
My C# skills are very limited, so far but i try.
This scripts is my attempt to be able to rotate a gameobject by holding right mouse button down and dragging ingame.
But it is wrong.
Can anyone help me correct it?ยด
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class mouseM : MonoBehaviour
{
bool dragging = false;
void Start()
{
if (Input.GetMouseButtonDown(1))
{
dragging = true;
}
}
void Update()
{
if (Input.GetMouseButtonDown(1))
{
yourOnMouseDownFunction();
dragging = true;
}
if (Input.GetMouseButtonUp(1))
{
yourOnMouseUpFunction();
dragging = false;
}
if (dragging)
{
yourOnMouseDragFunction();
}
}
}
I understood that You need to Drag Object in 3d World so Here is my Code just create new Script and attach to Object You Want to Drag it
Your Object that You need to Drag it should has a collider
using UnityEngine;
public class DragableObject : MonoBehaviour
{
private Vector3 mOffset;
private float mZCoord;
private void OnMouseDrag()
{
transform.position = GetMouseWorldPos() + mOffset;
}
private void OnMouseDown()
{
mZCoord = Camera.main.WorldToScreenPoint(gameObject.transform.position).z;
mOffset = transform.position - GetMouseWorldPos();
}
private Vector3 GetMouseWorldPos()
{
Vector3 mosePoint = Input.mousePosition;
mosePoint.z = mZCoord;
var result = Camera.main.ScreenToWorldPoint(mosePoint);
return result;
}
}
you can try it by adding it to sphere or cube and if you use custom shape you should insure that the collider is in suitable size or has a meshcollier
Demo
EDIT
using UnityEngine;
public class DragableObject : MonoBehaviour
{
private bool isMouseDragging;
private Vector3 screenPosition;
private Vector3 offset;
private GameObject target;
GameObject ReturnClickedObject(out RaycastHit hit)
{
GameObject targetObject = null;
Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
if (Physics.Raycast(ray.origin, ray.direction * 10, out hit))
{
targetObject = hit.collider.gameObject;
}
return targetObject;
}
void Update()
{
if (Input.GetMouseButtonDown(1))
{
RaycastHit hitInfo;
target = ReturnClickedObject(out hitInfo);
if (target != null)
{
isMouseDragging = true;
Debug.Log("our target position :" + target.transform.position);
//Here we Convert world position to screen position.
screenPosition = Camera.main.WorldToScreenPoint(target.transform.position);
offset = target.transform.position - Camera.main.ScreenToWorldPoint(new Vector3(Input.mousePosition.x, Input.mousePosition.y, screenPosition.z));
}
}
if (Input.GetMouseButtonUp(1))
{
isMouseDragging = false;
}
if (isMouseDragging)
{
//tracking mouse position.
Vector3 currentScreenSpace = new Vector3(Input.mousePosition.x, Input.mousePosition.y, screenPosition.z);
//convert screen position to world position with offset changes.
Vector3 currentPosition = Camera.main.ScreenToWorldPoint(currentScreenSpace) + offset;
//It will update target gameobject's current postion.
target.transform.position = currentPosition;
}
}
}
You could try the Input.GetMouseButton method, this should return a value depending on if the button is held pressed.
This one works too, if someone needs in the future.
This is for rotate though.
Sorry, i dont know why it wont let me post as code, so i post an image.
enter image description here
I want to set the gravity modifier of an object to 2 when the mouse is clicked down, then go back down to .3 when it is released.
I think its just a simple stupid error.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Move : MonoBehaviour
{
public Rigidbody2D rb;
public float idle = .3f;
void Start()
{
rb = GetComponent<Rigidbody2D>();
}
void Update()
{
if (Input.GetMouseButtonDown(0))
{
rb.gravityScale = 2f;
}
else
{
rb.gravityScale = .3f;
}
}
}
GetMouseButtonDown will only return true on the exact frame that the mouse button was pressed down. This means that if you hold it down, your else block will run every frame other than the one it was pressed. You can instead check for the mouse being released with GetMouseButtonUp and change it back when that happens:
if (Input.GetMouseButtonDown(0))
{
rb.gravityScale = 2f;
}
if (Input.GetMouseButtonUp(0))
{
rb.gravityScale = .3f;
}
or you can be more specific with your first if and then use an empty else:
if (Input.GetMouseButtonDown(0) || Input.GetMouseButton(0))
{
rb.gravityScale = 2f;
}
else
{
rb.gravityScale = .3f;
}
GetMouseButton will return true during any frame it's held.

A problem arises when I try to modify the script with a touchable controller. I have googled many times and modified the script as I could, and still it gives me no result (btw, I'm new to Unity). Then I found a tutorial from a website about making a touch controller with a GUI Texture (TouchControls). I think that tutorial is easy to learn. Here is the script
using UnityEngine;
using System.Collections;
[RequireComponent(typeof (Rigidbody2D))]
[RequireComponent(typeof(BoxCollider2D))]
public class TouchControls : MonoBehaviour {
// GUI textures
public GUITexture guiLeft;
public GUITexture guiRight;
public GUITexture guiJump;
private Animator anim;
// Movement variables
public float moveSpeed = 5f;
public float jumpForce = 50f;
public float maxJumpVelocity = 2f;
// Movement flags
private bool moveLeft, moveRight, doJump = false;
void Start ()
{
anim = gameObject.GetComponent<Animator>();
}
// Update is called once per frame
void Update () {
// Check to see if the screen is being touched
if (Input.touchCount > 0)
{
// Get the touch info
Touch t = Input.GetTouch(0);
// Did the touch action just begin?
if (t.phase == TouchPhase.Began)
{
// Are we touching the left arrow?
if (guiLeft.HitTest(t.position, Camera.main))
{
Debug.Log("Touching Left Control");
moveLeft = true;
}
// Are we touching the right arrow?
if (guiRight.HitTest(t.position, Camera.main))
{
Debug.Log("Touching Right Control");
moveRight = true;
}
// Are we touching the jump button?
if (guiJump.HitTest(t.position, Camera.main))
{
Debug.Log("Touching Jump Control");
doJump = true;
}
}
// Did the touch end?
if (t.phase == TouchPhase.Ended)
{
// Stop all movement
doJump = moveLeft = moveRight = false;
}
}
// Is the left mouse button down?
if (Input.GetMouseButtonDown(0))
{
// Are we clicking the left arrow?
if (guiLeft.HitTest(Input.mousePosition, Camera.main))
{
Debug.Log("Touching Left Control");
moveLeft = true;
}
// Are we clicking the right arrow?
if (guiRight.HitTest(Input.mousePosition, Camera.main))
{
Debug.Log("Touching Right Control");
moveRight = true;
}
// Are we clicking the jump button?
if (guiJump.HitTest(Input.mousePosition, Camera.main))
{
Debug.Log("Touching Jump Control");
doJump = true;
}
}
if (Input.GetMouseButtonUp(0))
{
// Stop all movement on left mouse button up
doJump = moveLeft = moveRight = false;
}
}
void FixedUpdate()
{
//anim.SetFloat("Speed", Mathf.Abs);
// Set velocity based on our movement flags.
if (moveLeft)
{
rigidbody2D.velocity = -Vector2.right * moveSpeed;
}
if (moveRight)
{
rigidbody2D.velocity = Vector2.right * moveSpeed;
}
if (doJump)
{
// If we have not reached the maximum jump velocity, keep applying force.
if (rigidbody2D.velocity.y < maxJumpVelocity)
{
rigidbody2D.AddForce(Vector2.up * jumpForce);
} else {
// Otherwise stop jumping
doJump = false;
}
}
}
}
But I have no idea how to implement the script from the tutorial (TouchControls) and assign that to my player control script (PlayerCharacter). How can I combine both scripts so that a player can control it with a touchable control?
The best thing you can do is not to drag the touch controls from the touchcontrols tutorial to the playercontroller but the other way around, use the touchcontrols tutorial script as your template.
Since your playercontroller uses floats in its input such as moveleft = 50.0f; and the touchcontrols uses moveleft = true;
the scripts are very different from each other to just merge and work.
so from that in the touchcontrols leave the update function as it is,
and only update the fixedupate function with your controls logic since
the update void, is the condition controller for right, left, up & down so to speak.
and it will also handle the actual input of the touch.
the fixed update could then control some things that the playercontroller has such as
apply force when touching a tagged object or stuff like that.
and the update only does the input condition, good advice would be to wrap the update touch code in its own function so the update is not only touch but also other game logic related code.
You should search use copy the touch control script inside the player controller while changing the right parts. For example, instead of using Input.GetKeyDown you should use the Input.GetTouch but it depends on the game you are creating. You should pay attention to that code and change some parts
