i am developing endless game . when player dies then camera zoom and focus on player position. i try and almost done. To zoom the camera i use orthographicSize and focus to the player i use transform.LookAt() that focus the player position when player dies.but the problem is when camera Zoom the scene then entire scene gets rotate. i have created CameraScript and attached to the maincamera .
[SerializeField]
private Camera gameCam;
[SerializeField]
private Transform[] target;
IEnumerator ZoomIn(){
while (gameCam.orthographicSize > 3) {
yield return new WaitForSeconds (0.01f);
transform.LookAt (target [index]);
gameCam.orthographicSize -= 0.1f;
}
}
public void ZoomCam(){
StartCoroutine (ZoomIn ());
}
Help me to that Script if any mistake..Thanks..
I think it's happening because you're not setting the worldUp parameter when you're calling transform.LookAt(...).
I suggest using the camera's own current up vector as that parameter, i.e.
transform.LookAt (target [index], transform.up);
I hope that helps!
EDIT:
Of course, this would only work if your camera is originally oriented as you intend it to be. Else, you'll have to use the vector you choose as the second parameter there.

I'm creating a top down 2D game, where the player has to break down trees. I made it so the player casts a ray toward the mouse, and when the ray hits a tree, it should lower the tree's health. I don't get any errors when I run the game or click, but it seems like the tree isn't detecting the hits.
void Update()
{
...
if (Input.GetMouseButtonDown(0))
{
RaycastHit2D hit = Physics2D.Raycast(playerRb.transform.position, mousePosition - playerRb.transform.position, 2.0f);
if (hit.collider != null)
{
if (hit.collider == GameObject.FindWithTag("Tree"))
{
hit.collider.GetComponent<TreeScript>().treeHealth--;
}
}
}
}
Still pretty new to coding and I'm teaching myself, so please make your answer easy to understand to help me learn.
Input.mousePosition is equal to the pixel your mouse is on. This is very different than the location your mouse is pointing at in the scene. To explain further, Input.mousePosition is where the mouse is. Think about it. If the camera was facing up, the mouse positon would be the same, but where they are clicking is different.
Instead of using Input.mousePosition, You should pass this into a function called Ray Camera.ScreenPointToRay();
You just input the mouse position and then use this new ray to do the raycast.
ANOTHER EXTREMELY IMPORTANT THING 1: Do not use Camera.main in Update(), as it uses a GetComponet call, which can cause perormance decreases. Store a reference of it in your script and use that.
Extremely important thing 2: I notice you are using GetComponent to change the tree's health. This is fine, but do not use GetComponent if you don't have to.
Like this:
Camera cam;
void Start()
{
cam = Camera.main; //it is fine to use this in start,
//because it is only being called once.
}
void Update()
{
...
if (Input.GetMouseButtonDown(0))
{
Ray ray = cam.ScreenPointToRay(Input.mousePosition);
RaycastHit2D hit = Physics2D.Raycast(ray);
...
}
}
You need to convert your mouse position from screen point to world point with Z value same as the other 2D objects.
Vector3 Worldpos=Camera.main.ScreenToWorldPoint(mousePos);
Also use a Debug.DrawRay to check the Raycast
Debug.DrawRay(ray.origin, ray.direction*10000f,Color.red);

I'm currently trying to create a multiplayer game using mirror!
So far I've been successful in creating a lobby and set up a simple character model with a player locomotion script I've taken and learnt inside out from Sebastian Graves on YouTube (you may know him as the dark souls III tutorial guy)
This player locomotion script uses unity's package 'Input System' and is also dependent on using the camera's .forward and .right directions to determine where the player moves and rotates instead of using forces on the rigidbody. This means you actually need the camera free in the scene and unparented from the player.
Here is my HandleRotation() function for rotating my character (not the camera's rotation function):
private void HandleRotation()
{
// target direction is the way we want our player to rotate and move // setting it to 0
Vector3 targetDirection = Vector3.zero;
targetDirection = cameraManager.cameraTransform.forward * inputHandler.verticalInput;
targetDirection += cameraManager.cameraTransform.right * inputHandler.horizontalInput;
targetDirection.Normalize();
targetDirection.y = 0;
if (targetDirection == Vector3.zero)
{
// keep our rotation facing the way we stopped
targetDirection = transform.forward;
}
// Quaternion's are used to calculate rotations
// Look towards our target direction
Quaternion targetRotation = Quaternion.LookRotation(targetDirection);
// Slerp = rotation between current rotation and target rotation by the speed you want to rotate * constant time regardless of framerates
Quaternion playerRotation = Quaternion.Slerp(transform.rotation, targetRotation, rotationSpeed * Time.deltaTime);
transform.rotation = playerRotation;
}
It's also worth mentioning I'm not using cinemachine however I'm open to learning cinemachine as it may be beneficial in the future.
However, from what I've learnt and managed to find about mirror is that you have to parent the Main Camera under your player object's prefab so that when multiple people load in, multiple camera's are created. This has to happen on a Start() function or similar like OnStartLocalPlayer().
public override void OnStartLocalPlayer()
{
if (mainCam != null)
{
// configure and make camera a child of player
mainCam.orthographic = false;
mainCam.transform.SetParent(cameraPivotTransform);
mainCam.transform.localPosition = new Vector3(0f, 0f, -3f);
mainCam.transform.localEulerAngles = new Vector3(0f, 0f, 0f);
cameraTransform = GetComponentInChildren<Camera>().transform;
defaultPosition = cameraTransform.localPosition.z;
}
}
But of course, that means that the camera is no longer independent to the player and so what ends up happening is the camera rotates when the player rotates.
E.g. if I'm in game and looking to the right of my player model and then press 'w' to walk in the direction the camera is facing, my camera will spin with the player keeping the same rotation while my player spins in order to try and walk in the direction the camera is facing.
What my question here would be: Is there a way to create a system using mirror that doesn't require the camera to be parented to the player object prefab on start, and INSTEAD works by keeping it independent in the scene?
(I understand that using forces on a rigidbody is another method of creating a player locomotion script however I would like to avoid that if possible)
If anybody can help that would be greatly appreciated, Thank You! =]
With the constraint of your camera being attached to the player you will have to adapt the camera logic. What you can do is instantiate a proxy transform for the camera and copy that transforms properties to your camera, globally, every frame. The parent constraint component might do this for you. Then do all your transformations on that proxy.
Camera script with instantiation:
Transform proxy;
void Start(){
proxy = (new GameObject()).transform;
}
void Update(){
//transformations on proxy
transform.position = proxy.position;
transform.rotation = proxy.rotation;
}
So, here's my error! im designing a FPS game in unity and im scripting an AI enemy (for now it just moves around randomly) im also using NeoFPS that should be all the background info out of the way as for whats happening:
i can see the enemy in scene view and i can see it in the game view before i press play, when i do press play the enemy disappears in game view but i can still see it trying to move around the little box i put it in and stuff of the sorts via navmesh etc. the collider for the enemy is still there when i go into the box however i cant see it and i shoot through it and do no damage to it whatsoever i will include screenshots and my AI code below (the white capsule is the enemy w AI script inside a little box, the camera is the FPS player
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.AI;
public class AICharacterController : MonoBehaviour
{
private NavMeshAgent m_Agent;
private void Awake()
{
m_Agent = GetComponent<NavMeshAgent>();
}
Vector3 movePosition;
void Update()
{
if (movePosition == Vector3.zero
|| Vector3.Distance(transform.position, m_Agent.destination) < 1)
{
SelectNewDestination();
}
}
void SelectNewDestination()
{
Vector2 pos = Random.insideUnitCircle * 50;
movePosition.x = pos.x;
movePosition.y = pos.y;
NavMeshHit hit = default;
if (NavMesh.SamplePosition(movePosition, out hit, 4, NavMesh.AllAreas))
{
m_Agent.SetDestination(hit.position);
}
}
public void Die()
{
Destroy(gameObject, 0.25f);
}
}
(if you dont see an image below then stackoverflow replaced it with a link and its not working)
If things are invisible in a camera, but not in the scene view then that means that the "Culling Mask" property on the camera is set to ignore the layers the object is on. NeoFPS uses a spawning system, so its quite possible that the camera in the character that's spawned has a different culling mask setup to the camera in the scene that you're looking through outside of play mode. To fix that you would have to find the camera in the character prefab's hierarchy (usually called PlayerCameraSpring) and add your AI's layer to its culling mask.
I have a planet and a player moving on it using gravity. I would like to have a camera to follow the player around it. Using the Parent Constraint component works perfectly, but I want to delay the rotation follow, so I have to use a script. I just cannot figure out how to make it follow it around the globe. I either have a camera that completely freaks out, or a camera that sort of follows the player but doesn't move over the planet and always stays in front of it. And often the position following works, but as soon as I add something that changes rotation it only does that. I've tried many different scripts but nothing works. I'm grateful for any help.
EDIT
I'm sorry for not adding an example. At the moment I've tried this script attached to the camera:
public class CameraFollow : MonoBehaviour
{
public GameObject player;
private Vector3 offset;
void Start()
{
offset = transform.position - player.transform.position;
}
void LateUpdate()
{
transform.rotation = Quaternion.Slerp(transform.rotation, player.transform.rotation, 50f * Time.deltaTime);
transform.position = player.transform.position + offset;
}
The camera does mimic the rotation of the player, but the position isn't being follow correctly anymore. It seems mostly stuck in place, moving only very slightly.
In order to have a camera following a GameObject, you need to go to the camera you want following the GameObject, select Add component, write FollowPlayer, press New script, and then press select and add. Edit the script so it contains the following:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class FollowPlayer : MonoBehaviour
{
public Transform player;
public Vector3 offset;
// Update is called once per frame
void Update()
{
transform.position = player.position + offset;
}
}
Then, you will need to drag and drop the GameObject you want the camera to follow, in the "Player" box.
Define the offset of the camera from the GameObject, and your'e good to go.
I have made a gameobject together with some children gameobject to represent the information to show up when specific circumstances occurred.
I have already ajusted the position of the information gameobject(together with its' children) in the cameraarea. The thing is that I want to move the gameobject(together with its' children) out of the camera, maybe on top or maybe on left. Following is the scratch to demonstrate the position I want to put it:
So that I could move the information gameobject and its' children (Red box) with some movement effect when needed, I have no problem with moving it back but could find an elegant way to move it out of the camera when the game started.
Mostly because I don't know how to calculate the position out of the camera.
Maybe find the upper border of the camera and the size of the gameobject and its children?
I know I could do this by maybe add a marker gameobject to represent the downer border of the information gameobject, and move it until it's not visible, but is there a more elegant way?
Any ideas?
For this one, I would use the following trick: use any method (animation, coroutine, Update method...) to move your item out of screen the way you desire. Then you can use the OnBecameInvisible event which is called when the item does not need to be rendered on any camera anymore. The event will there be used to detect that the parent object moved out of screen, and that you want to stop the current movement. You then just need to define in this event that you want to stop the current moving behavior, and you will be done.
void OnBecameInvisible() {
// Stop moving coroutine, moving in Update or current animation.
}
There are probably more elegant ways of doing it as you said, but I think this method should be enough for what you want to achieve.
It took me time, but I found this way for you, attach this script to your gameObject:
public Renderer rend;
//drag the camera to the script in the inspector
public Camera camera1;
Vector3 bottomleft;
Vector3 topright;
void Start()
{
rend = GetComponent<Renderer>();
//the top-right point of the camera bounds
topright= camera1.ViewportToWorldPoint(new Vector3(0, 0, transform.position.z));
//the bottom-left point of the camera bounds
bottomleft = camera1.ViewportToWorldPoint(new Vector3(1, 1, transform.position.z));
StartCoroutine(MoveUp());
}
IEnumerator MoveUp()
{
//while the position and the height are lower that the Y of top right
while (transform.position.y + rend.bounds.size.y < topright.y)
{
//move the object to the new position (move it up)
transform.position = new Vector3(transform.position.x, transform.position.y + .01f, transform.position.z);
//and wait for 1/100 of a second
yield return new WaitForSecondsRealtime(.001f);
}
}
you can play with the WaitForSecondsRealtime value to change the velocity of moving.
