I am following Survival Shooter unity tutorial and in the tutorial the down given code is used to make the camera follow the player.The code is working but how can i alter it so that it stops following the player at a given X and Y point.
code
public Transform target; // The position that that camera will be following.
public float smoothing = 5f; // The speed with which the camera will be following.
Vector3 offset; // The initial offset from the target.
void Start ()
{
// Calculate the initial offset.
offset = transform.position - target.position;
}
void FixedUpdate ()
{
// Create a postion the camera is aiming for based on the offset from the target.
Vector3 targetCamPos = target.position + offset;
// Smoothly interpolate between the camera's current position and it's target position.
transform.position = Vector3.Lerp (transform.position, targetCamPos, smoothing * Time.deltaTime);
}
Simply stop updating his position:
private bool followPlayer = true;
void FixedUpdate ()
{
if(followPlayer){
// Create a postion the camera is aiming for based on the offset from the target.
Vector3 targetCamPos = target.position + offset;
// Smoothly interpolate between the camera's current position and it's target position.
transform.position = Vector3.Lerp (transform.position, targetCamPos, smoothing * Time.deltaTime);
}
}
Change the value of followPlayer to false and it will stop following
To determine if the player is at given point, you need to check distance between the player and the point, e.g:
public Transform target; // player position
public Transform stopingPoint; // stopping point position
public double tolerance; // the "radius" of stopping point
private bool followPlayer = true;
...
void FixedUpdate ()
{
if(!followPlayer)
return;
followPlayer = Vector3.Distance(target.position, stopingPoint.position) <= tolerance;
...

I'm attempting to make the ability to slide in an FPS game I'm working on and I've tried rotating the player object but when tested, it does nothing. Pressing the slide key I have assigned does nothing but rotate the player object in the Y and Z axis (I'm trying to rotate it on the X axis)
Here's the code I'm using (only relevant parts have been kept in):
public class SlideMovementScript : MonoBehaviour
{
public Rigidbody rig;
public CapsuleCollider capcol;
public GameObject player;
public float originalHeight;
public float reducedHeight;
public float slideSpeed = 10f;
// Start is called before the first frame update
void Start()
{
capcol = GetComponent<CapsuleCollider>();
rig = GetComponent<Rigidbody>();
originalHeight = capcol.height;
}
// Update is called once per frame
void Update()
{
if (Input.GetKeyDown(KeyCode.LeftControl) && Input.GetKey(KeyCode.W))
Sliding();
else if (Input.GetKeyUp(KeyCode.LeftControl))
GoUp();
}
private void Sliding()
{
capcol.height = reducedHeight;
player.transform.localRotation = Quaternion.Euler(1.599f, 0f, 0f);
rig.AddForce(transform.forward * slideSpeed, ForceMode.VelocityChange);
}
private void GoUp()
{
GetComponent<CapsuleCollider>().height = originalHeight;
player.transform.localRotation = Quaternion.Euler(0f, 0f, 0f);
}
}
I've gotten ZERO error messages from this but I haven't managed to find the problem
Another problem I've also had is when you start sliding, it just instantly rotates the Player object to X 1.599 Y 0 Z 0. I want it to rotate to where the player is facing but I haven't found a way to do it, even using transform.foward or other references won't work.
The Explanation (skip to script if you want) (read notes)
I reccomend using Quaternion's methods. You can use Quaternion.Slerp which can smooth out the rotation towards the player.
Slerp means spherical linear interpolation
Basically, Slerp is a 3 argumented method. the first argument is the current rotation, the second argument is the target rotation, and the third is at which point between those two you want to output.
More simply, Lerp is linear interpolation. Lerps arguments are the same, except it handles floats and not Quaternions. If you Mathf.Lerp(0,1,1); you will get 1, because 1 is all the ay to the second argument. If you do Mathf(0, 3, 0.5); you will get 1.5 because 1.5 is halfway (0.5) between them both.
You can imagine slerp like that, if you give rotation (90, 0, 0) and alerp it to (0, 0, 0) by 0.5 you will get (45, 0, 0).
On this example, I slerp from the current rotation, to the target rotation, by delta time. This way, as time goes on, it slightly increases the current rotation to be the target.
I can create the target as 1.599 rotated on the x.
To make this relative Make a parent game object to the player containing the mesh and rigidbody and maybe the collider (depends if you want the collider upright). I will call this "slidePlayer" slidePlayer must be a child of the player gameObject
Notes
Make sure to have slidePlayer to a gameObject that is a child of player, but must have the player mesh or sliding won't be visible.
Change rot to the target rotation.
Change speed to speed to rotate to the target rotation.
Here is your script I changed:
public class SlideMovementScript : MonoBehaviour
{
public Rigidbody rig;
public CapsuleCollider capcol;
public GameObject player;
public GameObject slidePlayer;
public float originalHeight;
public float reducedHeight;
public float slideSpeed = 10f;
// Start is called before the first frame update
void Start()
{
capcol = GetComponent<CapsuleCollider>();
rig = GetComponent<Rigidbody>();
originalHeight = capcol.height;
}
// Update is called once per frame
void Update()
{
if (Input.GetKeyDown(KeyCode.LeftControl) && Input.GetKey(KeyCode.W))
Sliding();
else if (Input.GetKeyUp(KeyCode.LeftControl))
GoUp();
}
private void Sliding()
{
capcol.height = reducedHeight;
Quaternion rot = Quaternion.Euler(1.599f, 0f, 0f);
float speed = 1f;
Quaternion curRot = slidePlayer.transform.localRotation;
slidePlayer.transform.localRotation = Quaternion.Slerp(curRot, rot, Time.deltaTime * speed);
rig.AddForce(transform.forward * slideSpeed, ForceMode.VelocityChange);
}
private void GoUp()
{
GetComponent<CapsuleCollider>().height = originalHeight;
Quaternion rot = Quaternion.Euler(0f, 0f, 0f);
float speed = 3f;
Quaternion curRot = slidePlayer.transform.localRotation;
slidePlayer.transform.localRotation = Quaternion.Slerp(curRot, rot, Time.deltaTime * speed);
}
}
Let me know if there are any problems in coments. Thanks.
I know I should have posted this question on Unity's questions page but I actually did and haven't received an answer for 3 days.
So I'm trying to make the character face the direction it is moving but I can't make it work. I'm working on a 3d game with a diablo-style camera but without depending on the mouse, and I'm using the script from 'Survival Shooter' as a reference.
Here's the movement script:
public float speed = 6f; // The speed that the player will move at.
public float rotateSpeed = 2f;
public Camera playerCam;
Vector3 movement; // The vector to store the direction of the player's movement.
Animator anim; // Reference to the animator component.
Rigidbody playerRigidbody; // Reference to the player's rigidbody.
int floorMask; // A layer mask so that a ray can be cast just at gameobjects on the floor layer.
float camRayLength = 100f; // The length of the ray from the camera into the scene.
Vector3 rotationY;
void Awake ()
{
// Create a layer mask for the floor layer.
floorMask = LayerMask.GetMask ("Floor");
// Set up references.
anim = GetComponent <Animator> ();
playerRigidbody = GetComponent <Rigidbody> ();
}
void FixedUpdate ()
{
// Store the input axes.
float h = Input.GetAxisRaw ("Horizontal");
float v = Input.GetAxisRaw ("Vertical");
// Move the player around the scene.
Move (h, v);
// Turn the player to face the mouse cursor.
Turning (h, v);
}
void Move (float h, float v)
{
// Move the player to it's current position plus the movement.
Vector3 targetDirection = new Vector3(h, 0f, v);
targetDirection = Camera.main.transform.TransformDirection(targetDirection);
targetDirection = targetDirection.normalized * speed * Time.deltaTime;
targetDirection.y = 0.0f;
playerRigidbody.MovePosition (transform.position + targetDirection);
}
void Turning(float y, float x)
{
if (y != 0) {
rotationY.Set (0f, y, 0f);
//rotationY = rotationY.normalized * (5 * rotateSpeed);
Quaternion deltaRotation = Quaternion.Euler (rotationY);
playerRigidbody.MoveRotation (deltaRotation);
}
}
However when I move the character it always faces the bottom-left side of the screen. How can I fix that?
Hi guys i have a problem with that code:
using UnityEngine;
using UnitySampleAssets.CrossPlatformInput;
namespace CompleteProject
{
public class PlayerMovement : MonoBehaviour
{
public float speed = 6f; // The speed that the player will move at.
Vector3 movement; // The vector to store the direction of the player's movement.
Animator anim; // Reference to the animator component.
Rigidbody playerRigidbody; // Reference to the player's rigidbody.
#if !MOBILE_INPUT
int floorMask; // A layer mask so that a ray can be cast just at gameobjects on the floor layer.
float camRayLength = 100f; // The length of the ray from the camera into the scene.
#endif
void Awake ()
{
#if !MOBILE_INPUT
// Create a layer mask for the floor layer.
floorMask = LayerMask.GetMask ("Floor");
#endif
// Set up references.
anim = GetComponent <Animator> ();
playerRigidbody = GetComponent <Rigidbody> ();
}
void FixedUpdate ()
{
// Store the input axes.
float h = CrossPlatformInputManager.GetAxisRaw("Horizontal");
float v = CrossPlatformInputManager.GetAxisRaw("Vertical");
// Move the player around the scene.
Move (h, v);
// Turn the player to face the mouse cursor.
Turning ();
// Animate the player.
Animating (h, v);
}
void Move (float h, float v)
{
// Set the movement vector based on the axis input.
movement.Set (h, 0f, v);
// Normalise the movement vector and make it proportional to the speed per second.
movement = movement.normalized * speed * Time.deltaTime;
// Move the player to it's current position plus the movement.
playerRigidbody.MovePosition (transform.position + movement);
}
void Turning ()
{
#if !MOBILE_INPUT
// Create a ray from the mouse cursor on screen in the direction of the camera.
Ray camRay = Camera.main.ScreenPointToRay (Input.mousePosition);
// Create a RaycastHit variable to store information about what was hit by the ray.
RaycastHit floorHit;
// Perform the raycast and if it hits something on the floor layer...
if(Physics.Raycast (camRay, out floorHit, camRayLength, floorMask))
{
// Create a vector from the player to the point on the floor the raycast from the mouse hit.
Vector3 playerToMouse = floorHit.point - transform.position;
// Ensure the vector is entirely along the floor plane.
playerToMouse.y = 0f;
// Create a quaternion (rotation) based on looking down the vector from the player to the mouse.
Quaternion newRotatation = Quaternion.LookRotation (playerToMouse);
// Set the player's rotation to this new rotation.
playerRigidbody.MoveRotation (newRotatation);
}
#else
Vector3 turnDir = new Vector3(CrossPlatformInputManager.GetAxisRaw("Mouse X") , 0f , CrossPlatformInputManager.GetAxisRaw("Mouse Y"));
if (turnDir != Vector3.zero)
{
// Create a vector from the player to the point on the floor the raycast from the mouse hit.
Vector3 playerToMouse = (transform.position + turnDir) - transform.position;
// Ensure the vector is entirely along the floor plane.
playerToMouse.y = 0f;
// Create a quaternion (rotation) based on looking down the vector from the player to the mouse.
Quaternion newRotatation = Quaternion.LookRotation(playerToMouse);
// Set the player's rotation to this new rotation.
playerRigidbody.MoveRotation(newRotatation);
}
#endif
}
void Animating (float h, float v)
{
// Create a boolean that is true if either of the input axes is non-zero.
bool walking = h != 0f || v != 0f;
// Tell the animator whether or not the player is walking.
anim.SetBool ("IsWalking", walking);
}
}
}
I have tried many ways , but unfortunately none of them works , I need that my player can jump , and maybe even do a double jump . I just can not figure out how to blow it up .
I say thanks to those who will help me.
You need to use RigidBody's AddForce function: http://docs.unity3d.com/ScriptReference/Rigidbody.AddForce.html
As in the example, use a Vector3.Up multiplied by the force of your jump.
You can include this code in the FidexUpdate function. If the jump key is down (http://docs.unity3d.com/ScriptReference/Input.GetKeyDown.html), then AddForce to the player.
Okay, So I have come this far:
public class CameraScript : MonoBehaviour {
public void RotateCamera()
{
float x = 5 * Input.GetAxis("Mouse X");
float y = 5 * -Input.GetAxis("Mouse Y");
Camera.mainCamera.transform.parent.transform.Rotate (y,x,0);
}
}
My camera has a parent which I rotate based on my mouse position. The only problem is that I can only swipe with the mouse to rotate the object. How can I rotate the object which is my camera is attached to based on my mouse position if I just click next to the object. Thanks in advance!
The value will be in the range -1...1 for keyboard and joystick input.
If the axis is setup to be delta mouse movement, the mouse delta is
multiplied by the axis sensitivity and the range is not -1...1. Unity Document
Note: This link is usefull please check it.
So you need to change your code like this.
public void RotateCamera()
{
Vector3 mousePosition = Camera.main.ScreenToWorldPoint(Input.mousePosition); // Gets mouse position to Unity World coordinate system
Camera.mainCamera.transform.parent.transform.Rotate (mousePosition);
}
if there are problem you can do like this
public void RotateCamera()
{
Vector3 position = new Vector3(Input.mousePosition.x, Input.mousePosition.y,0);
Vector3 mousePosition = Camera.main.ScreenToWorldPoint(position); // Gets mouse position to Unity World coordinate system
Camera.mainCamera.transform.parent.transform.Rotate (mousePosition);
}
one more option is rotateTowards.
public float speed=10; //any value > 0
public void RotateCamera()
{
Vector3 targetDir = Camera.main.ScreenToWorldPoint(Input.mousePosition) - Camera.mainCamera.transform.parent.transform.position;
float step = speed * Time.deltaTime;
Vector3 newDir = Vector3.RotateTowards(transform.forward, targetDir, step, 0.0F);
Camera.mainCamera.transform.parent.transform.rotation = Quaternion.LookRotation(newDir);
}
Maybe some syntax errors, i don't check them.
When I want to move Camera from origin position to destination position,it looks so stiff.So if it can set move speed accordding to offset,how to do ?
There is a nice tutorial on this problem, it is normally described at the beginning of all tutorials on the unity website. Inside the Survival Shooter Tutorial there is a explanation how to make the movement of the camera to the destination position smooth while moving.
Here is the code for moving the camera. Create a script, add it to the camera and add the GameObject you want to move to, into the scripts placeholder. It will automatically save the Transform component like setup in the script. (In my case its the player of the survival shooter tutorial ):
public class CameraFollow : MonoBehaviour
{
// The position that that camera will be following.
public Transform target;
// The speed with which the camera will be following.
public float smoothing = 5f;
// The initial offset from the target.
Vector3 offset;
void Start ()
{
// Calculate the initial offset.
offset = transform.position - target.position;
}
void FixedUpdate ()
{
// Create a postion the camera is aiming for based on
// the offset from the target.
Vector3 targetCamPos = target.position + offset;
// Smoothly interpolate between the camera's current
// position and it's target position.
transform.position = Vector3.Lerp (transform.position,
targetCamPos,
smoothing * Time.deltaTime);
}
}
You can use iTween plugins. And if you want your camera to move with your object ie to follow it smoothly. You can use smoothFollow script.
Have you tried using Vector3.MoveTowards? You can specify the step size to use, which should be smooth enough.
http://docs.unity3d.com/Documentation/ScriptReference/Vector3.MoveTowards.html
public Vector3 target; //The player
public float smoothTime= 0.3f; //Smooth Time
private Vector2 velocity; //Velocity
Vector3 firstPosition;
Vector3 secondPosition;
Vector3 delta;
Vector3 ca;
tk2dCamera UICa;
bool click=false;
void Start(){
ca=transform.position;
UICa=GameObject.FindGameObjectWithTag("UI").GetComponent<tk2dCamera>();
}
void FixedUpdate ()
{
if(Input.GetMouseButtonDown(0)){
firstPosition=UICa.camera.ScreenToWorldPoint(Input.mousePosition);
ca=transform.position;
}
if(Input.GetMouseButton(0)){
secondPosition=UICa.camera.ScreenToWorldPoint(Input.mousePosition);
delta=secondPosition-firstPosition;
target=ca+delta;
}
//Set the position
if(delta!=Vector3.zero){
transform.position = new Vector3(Mathf.SmoothDamp(transform.position.x, target.x, ref velocity.x, smoothTime),Mathf.SmoothDamp( transform.position.y, target.y, ref velocity.y, smoothTime),transform.position.z);
}
}
