We have got various controllers developed for moving gameobjects. I have used magnetometer/gyro sensor to move game object using MUVSlide through following code:
using UnityEngine;
using ForestIndieGames.Muvslide;
public class Connection : MonoBehaviour {
private static bool created = false;
private bool newInputAvailable;
private MuvslideConnection muvslideConn;
private void Awake()
{
if (!created)
{
DontDestroyOnLoad(this.gameObject);
created = true;
muvslideConn = new MuvslideConnection();
}
}
private void OnApplicationQuit()
{
if (muvslideConn != null)
muvslideConn.Close();
}
private void Update()
{
if (muvslideConn.GetInputManager().IsNewMotionAvailable())
newInputAvailable = true;
}
public bool IsNewInputAvailable()
{
bool result = newInputAvailable;
newInputAvailable = false;
return result;
}
public Vector3 GetAngles()
{
float[] angles = muvslideConn.GetInputManager().GetOrientationDegrees();
return new Vector3(angles[0], angles[1], angles[2]);
}
}
What I am trying to achieve is to move a gameobject by a real light spot on the wall. The spot is on the wall and fed through a camera. When the spot moves I want game object to follow exactly. The light spot can be a specific color or IR or UV etc.
Any leads please

I'm trying to make a animated UI and I wanna destroy the object after the player left the Collider and I don't really seem to find a way to do that.

I'm trying to make a animated UI and I wanna destroy the object after the player left the Collider and I don't really seem to find a way to do that.
I think the following is in the wrong place:
if (crateOpened == true)
{
Destroy(animateObject);
}
Try moving this inside the if statement in OnTriggerExit2D. What you are doing now is destroying your animateObject before it is animated. What I think you want is for animateObject to be destroyed when the player leaves the collider.
I've run up against a little problem, and I can't seem to find the solution.
I'm putting together a game in Unity3d that includes these gauntlets that can control the environment, i.e. raise downed bridges, open doors, etc. First, I'm just trying to allow the gauntlets to access objects from afar, and I found a telekinesis tutorial online that I am trying to pseudo-repurpose.
This script is supposed to raise a bridge (hence BridgeMover) until it hits a specific position and then lock it in place. Unfortunately, I'm throwing a null reference exception when the bridge hits the "lockbox" object, which is a small cube on the edge of the bridge ramp leading up to the bridge. I know this is simple, but I can't quite conceptualize it, and I've just been staring at it for a few days. This is my big issue, and any help would be appreciated.
In other news, I'm also trying to have the bridge rise as a flat plane instead of following the rotation of the cast ray, and would appreciate any advice about that as well, but I would understand if y'all want me to suffer through on that one. I'm pretty sure it has something to do with the Lerp, which I still don't really understand.
In the hierarchy, I have a handhold object, which is a child of the gauntlet object, which is a child of the camera, which is a child of the player. So
Player
Camera
Gauntlet
handHold
The lockbox object is a child of the ramp that it's attached to. So:
Ramp
Lockbox
Also, this isn't a criticism of the tutorial; I'm just swimming slightly out of my depths here. The tutorial, for those interested, can be found here.
public class HandController : MonoBehaviour
{
public static BridgeMover instance;
public Camera mainCamera;
Rigidbody rbOfHeldObject;
GameObject heldObject;
public GameObject handHold;
bool holdsObject = false;
float interactionDistance = 100;
float slideSpeed = 2;
Quaternion currentRotation;
private void Start()
{
mainCamera.GetComponent<Camera>();
}
private void Update()
{
//HandMove();
if (Input.GetMouseButtonDown(0) && !holdsObject)
Raycast();
if (Input.GetMouseButtonUp(0) && holdsObject)
ReleaseObject();
if (holdsObject && instance.LockPos())
LockObject();
if(holdsObject)
{
if (CheckDistance() >= 0.1f)
MoveObjectToPosition();
}
}
private void Raycast()
{
Ray ray = mainCamera.ViewportPointToRay(new Vector3(0.5f, 0.5f, 0));
RaycastHit hit;
if (Physics.Raycast(ray, out hit, interactionDistance))
{
if(hit.collider.CompareTag("Bridge"))
{
heldObject = hit.collider.gameObject;
heldObject.transform.SetParent(handHold.transform);
holdsObject = true;
rbOfHeldObject = heldObject.GetComponent<Rigidbody>();
rbOfHeldObject.constraints = RigidbodyConstraints.FreezeAll;
}
}
}
public float CheckDistance()
{
return Vector3.Distance(heldObject.transform.position, handHold.transform.position);
}
private void MoveObjectToPosition()
{
currentRotation = heldObject.transform.rotation;
heldObject.transform.position = Vector3.Lerp(heldObject.transform.position,
handHold.transform.position, slideSpeed * Time.deltaTime);
heldObject.transform.rotation = currentRotation;
}
private void ReleaseObject()
{
rbOfHeldObject.constraints = RigidbodyConstraints.None;
heldObject.transform.parent = null;
heldObject = null;
holdsObject = false;
}
private void LockObject()
{
rbOfHeldObject.useGravity = false;
heldObject.transform.parent = null;
heldObject = null;
holdsObject = false;
}
}
And then in the BridgeMover class:
public class BridgeMover : MonoBehaviour
{
public static BridgeMover instance;
bool lockPos = false;
private void OnCollisionEnter(Collision collision)
{
if (collision.gameObject.tag == "LockBox")
{
lockPos = true;
}
}
public bool LockPos()
{
return lockPos;
}
}
Any help would be appreciated. Also, if any further information is needed, let me know and I'll add it.
It looks like you're trying to implement a singleton instance for BridgeMover. Unfortunately, you don't have your instance defined. Here's the standard Unity method for creating a singleton implemented in your BridgeMover code:
public class BridgeMover : MonoBehaviour
{
public static BridgeMover instance;
bool lockPos = false;
void Awake()
{
if(instance == null)
{
instance = this;
}
else
{
Destroy(this.gameObject);
}
}
private void OnCollisionEnter(Collision collision)
{
if (collision.gameObject.tag == "LockBox")
{
lockPos = true;
}
}
public bool LockPos()
{
return lockPos;
}
}
Additionally, in your HandController class you should not declare a static BridgeMover. Instead, reference the static instance properly:
public static BridgeMover instance;
if (holdsObject && BridgeMover.instance.LockPos())
I am making sniper game, I have 2 cameras, one is rendering whole environment, and second one is in scope of the gun, which has high zoom quality.
I am able to show, enemy point on screen through main camera. and it shows proper on main camera, but in scope camera(2nd camera), it not showing properly. I want to show these points exactly same as enemy is.
here is my script to show point so far. I am attaching screen shots, first one is for scope camera and does not showing proper place, and 2nd one is for main camera, showing at proper place (Red circle is pointing)
using UnityEngine;
using UnityEngine.UI;
public class identity_shower : MonoBehaviour {
public Texture tex;
public GameObject helt;
public bool target_is_high =false;
private int counter_for_high = -1;
private int counter_for_low = -1;
private int counter_value = 50;
private bool bool_for_high = false;
private bool bool_for_low = false;
private Camera scope_cam_active;
private RectTransform rectTransform;
private Vector2 uiOFFset;
// Update is called once per frame
void OnGUI()
{
GameObject[] objs = GameObject.FindGameObjectsWithTag("enemy_soldier");
if( objs.Length<=0 )
{
return;
}
if (bool_for_high)
{
Vector2 pos_to_display = Camera.main.WorldToScreenPoint (this.transform.position);
GUI.DrawTexture (new Rect(pos_to_display.x-10.0f,(Screen.height- pos_to_display.y)-40.0f,15,15),tex);
}
}
public void show_your_identity()
{
if (target_is_high) {
if (counter_for_high >= counter_value)
{
return;
}
counter_for_high = counter_for_high + 1;
if (counter_for_high >= counter_value)
{
bool_for_high = true;
}
} else if(!target_is_high)
{
if (counter_for_low >= counter_value)
{
return;
}
counter_for_low = counter_for_low + 1;
if (counter_for_low >= counter_value)
{
bool_for_low = true;
}
}
}
}
Title says it all.
I provided an NPC with the following script, which should make him look and bark at the player.
When the player comes into the NPC's reach, however, the NPC starts walking towards the player instead of just facing him.
Any thoughts?
using UnityEngine;
public class Barking : MonoBehaviour {
public AudioSource barkingAudio;
private GameObject player;
private bool barking;
void Start () {
player = GameObject.FindGameObjectWithTag("Player");
barking = false;
}
void Update () {
if (barking)
lookAtPlayer();
}
private void lookAtPlayer()
{
transform.LookAt(player.transform.position, Vector3.up);
}
private void OnTriggerEnter(Collider other)
{
if (other.gameObject == player)
{
barking = true;
barkingAudio.mute = false;
barkingAudio.Play();
}
}
private void OnTriggerExit(Collider other)
{
if (other.gameObject == player) {
barking = false;
barkingAudio.mute = true;
barkingAudio.Stop();
}
}
}
Since I was using a Rigidbody and rotating the transform manually, there was some unexpected behaviour.
I found some code online which I could replace the Transform.LookAt method with:
var qTo = Quaternion.LookRotation(player.transform.position - transform.position);
qTo = Quaternion.Slerp(transform.rotation, qTo, 10 * Time.deltaTime);
GetComponent<Rigidbody>().MoveRotation(qTo);
This fixed my problem!
Imagine I have 2 gameobjects, red plate and apple.
When game start(this is crucial), apple already on red plate(2 gameobjects already in contact). so if I move red plate, the apple is "parented" to red plate and follow the transform.
How can I do that in Unity3D? I look at the code Trigger and Collision, both of them need to at least a stage that 1 moving gameobject to collide the other, which I don't have that.
Any idea how to deal with this?
I found the solution: Bounds.Intersect
As in:
var bounds1 = gameObject1.renderer.bounds;
var bounds2 = gameObject2.renderer.bounds;
if (bounds1.Intersects(bounds2))
{
// do something
}
So with this, my problem solved.
Probably the simplest implementation is to use OnTriggerEnter and OnTriggerExit to toggle the parenting of one object's transform to another, so that all children of the parent will accept the transform operations performed on the parent.
Example:
using UnityEngine;
[RequireComponent(typeof(BoxCollider))]
[RequireComponent(typeof(Rigidbody))]
public class
PlateCollider : MonoBehaviour
{
private void
Awake()
{
rigidbody.isKinematic = false;
rigidbody.useGravity = false;
collider.isTrigger = false;
}
}
And
using UnityEngine;
[RequireComponent(typeof(SphereCollider))]
[RequireComponent(typeof(Rigidbody))]
public class
AppleCollider : MonoBehaviour
{
private void
Awake()
{
rigidbody.isKinematic = false;
rigidbody.useGravity = false;
collider.isTrigger = false;
}
private void
OnCollisionEnter(Collision collision)
{
PlateCollider tryGetPlate = collision.gameObject.GetComponent<PlateCollider>();
if (tryGetPlate != null)
{
transform.parent = tryGetPlate.gameObject.transform;
}
}
private void
OnCollisionExit(Collision collision)
{
PlateCollider tryGetPlate = collision.gameObject.GetComponent<PlateCollider>();
if (tryGetPlate != null)
{
transform.parent = null;
}
}
}
There's many other ways you can use to compare the two objects. In this example I try to get the component on a colliding gameobject and check if the component reference exists. Collision tags might be a better option for you, it might not.
