I'm trying to follow the instructions in the unity documents how to use Inverse Kinematics in this page:
Inverse Kinematics
But i don't have the IK Animator Controller when i select Controller for the Animator.
I tried adding the script now. But the hand the right hand is folded to the other side. It's not like it's holding the flash light: The script is attached to the ThirdPersonController. And i dragged to the script in the Inspector to the rightHandObj the EthanRightHand and to the lookObj i dragged the Flashlight.
But the hand seems to be wrong way.
This is the script i'm using now the IKControl:
using UnityEngine;
using System;
using System.Collections;
[RequireComponent(typeof(Animator))]
public class IKControl : MonoBehaviour
{
protected Animator animator;
public bool ikActive = false;
public Transform rightHandObj = null;
public Transform lookObj = null;
void Start()
{
animator = GetComponent<Animator>();
}
//a callback for calculating IK
void OnAnimatorIK()
{
if (animator)
{
//if the IK is active, set the position and rotation directly to the goal.
if (ikActive)
{
// Set the look target position, if one has been assigned
if (lookObj != null)
{
animator.SetLookAtWeight(1);
animator.SetLookAtPosition(lookObj.position);
}
// Set the right hand target position and rotation, if one has been assigned
if (rightHandObj != null)
{
animator.SetIKPositionWeight(AvatarIKGoal.RightHand, 1);
animator.SetIKRotationWeight(AvatarIKGoal.RightHand, 1);
animator.SetIKPosition(AvatarIKGoal.RightHand, rightHandObj.position);
animator.SetIKRotation(AvatarIKGoal.RightHand, rightHandObj.rotation);
}
}
//if the IK is not active, set the position and rotation of the hand and head back to the original position
else
{
animator.SetIKPositionWeight(AvatarIKGoal.RightHand, 0);
animator.SetIKRotationWeight(AvatarIKGoal.RightHand, 0);
animator.SetLookAtWeight(0);
}
}
}
}
Add an empty game object to the flashlight and target that instead of the flashlight object itself. Hit play and then fiddle with the placement of the empty object until it is where you want it. Then just turn the flashlight into a prefab, stop play mode and make sure the flashlight in the scene matches the prefab (you can just use revert to do that if needed).
Now it would be doing exactly what you want every time. You could even have multiple prefabs with the empty object positioned differently to allow characters with larger or smaller hands to hold it convincingly.

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'm trying to get all tiles around the player in unity 2d tileset.
What I would like to happen when player presses U I Would like to get all tiles surrounding the player including the one underneath the player or simply the one 1 tile in front of them.
I'm trying to make a farming Game where when the player pulls out an item it will highlight on the tilemap where they are about to place it.
Please note I'm not asking for full code, I just want what ever solution allows me to get tiles near the players position
Edit, found a solution by editing someone elses code but im not sure if there's a better way, if not I would also like this to work based on player rotation currently it places a tile above the player. Code Source https://lukashermann.dev/writing/unity-highlight-tile-in-tilemap-on-mousever/
using System.Collections;
using System.Collections.Generic;
using Unity.Mathematics;
using UnityEngine;
using UnityEngine.Tilemaps;
public class PlayerGrid : MonoBehaviour
{
private Grid grid;
[SerializeField] private Tilemap interactiveMap = null;
[SerializeField] private Tilemap pathMap = null;
[SerializeField] private Tile hoverTile = null;
[SerializeField] private Tile pathTile = null;
public GameObject player;
private Vector3Int previousMousePos = new Vector3Int();
// Start is called before the first frame update
void Start()
{
grid = gameObject.GetComponent<Grid>();
}
// Update is called once per frame
void Update()
{
var px = Mathf.RoundToInt(player.transform.position.x);
var py = Mathf.RoundToInt(player.transform.position.y);
var tilePos = new Vector3Int(px, py, 0);
if (!tilePos.Equals(previousMousePos))
{
interactiveMap.SetTile(previousMousePos, null); // Remove old hoverTile
interactiveMap.SetTile(tilePos, hoverTile);
previousMousePos = tilePos;
}
// Left mouse click -> add path tile
if (Input.GetMouseButton(0))
{
pathMap.SetTile(tilePos, pathTile);
}
// Right mouse click -> remove path tile
if (Input.GetMouseButton(1))
{
pathMap.SetTile(tilePos, null);
}
}
}
try to use the layer field inside the inspector, you can create new Layers inside the Project Manager and there you can easily create Layers like "Background" "Scenery" "Player" "Foreground".. after this you can assign them individually to your Tiles also its important to have different grids otherwise you will not be able to assign different layers to it i hope it worked already
I want to attach an object to the OVRCameraRig and then use its position, which is offset from the rig.
However, my object is always static, irrespective of where the headset is.
This only happens with the OVRCameraRig. If I use a normal MainCamera I get the right data. But I'm not getting other aspects, like floor level, of the OVRCameraRig!
Is there some way to get the actual position of the OVRCameraRig?
Afaik the OVRCameraRig itself doesn't move.
What you probably want to get is the position of the centerEyeAnchor instead
// somehow get the reference e.g. using GetComponent
OVRCameraRig overCameraRig;
var position = overCameraRig.centerEyeAnchor.position;
Regardless of the value of usePerEyeCameras the centerEyeAnchor's position is always updated.
Try the following code to get the OVRCameraRig position using the centerEyeAnchor attribute.
using UnityEngine;
public class OVRCameraPosTest : MonoBehaviour {
[SerializeField] private OVRCameraRig overCameraRig;
void Start() {
Vector3 cameraPos = GetCameraPos();
Debug.Log("Camera Position: " + cameraPos);
}
Vector3 GetCameraPos() {
// Remove this line if you are refering the OVRCameraRig component
// through the inspector to the script.
overCameraRig = GameObject.Find("OVRCameraRig").GetComponent<OVRCameraRig>();
return overCameraRig.centerEyeAnchor.position;
}
}
I try to create a VR scene in unity using google cardboard sdk. I add a cube and CardboardMain.prefab to scene. There is an example scene that detect focus on cube. Its hierarchy view is :
I don't know how to add GUIReticle object or prefab like as the image.
How can I detect focus on an object?
Actually you could make the script by your own and it is quite simple.
You could detect whether the user is looking at your object or not by using RayCast from the Main Camera. If the RayCast hit your object, then it is being focused on.
For example:
using UnityEngine;
using System;
[RequireComponent(typeof(Collider))]
public class LookableObject : MonoBehaviour {
[SerializeField]
Transform cam; // This is the main camera.
// You can alternately use Camera.main if you've tagged it as MainCamera
bool focus; // True if focused
Collider gazeArea; // Your object's collider
public void Start () {
gazeArea = GetComponent<Collider> ();
}
public void Update () {
RaycastHit hit;
if (Physics.Raycast (cam.position, cam.forward, out hit, 1000f)) {
focus = (hit.collider == gazeArea);
} else {
focus = false;
}
}
}
Edit: This is just an example. You probably would want to make a script to do the Raycast only just once instead of doing the Raycast on each of your object over and over again to make your project runs faster.
I have 2 Spheres in my scene. I want to be able to drag and drop my mouse from one sphere to the other, and have an indicator (a straight line for example) while dragging. After releasing the mouse button, I want to store in the first sphere the other sphere (as GameObject).
I need this in UnityScript, but I can accept C# ideas.
So far I have thought about onMouseDown event on the first Sphere, and then onMouseEnter to the other sphere, I'll store the data in some global variable (which I donno how to do yet) and in case of onMouseExit I'll just put the global variable as null.
Then onMouseUp on the first Sphere I'll store the global variable in the pressed object (the sphere).
Any tips and tricks on how to do it?
Assumptions/Setup
You're working in a 2D worldspace; the logic for dragging the object for this part of the solution would need changing.
Setting parent after click drag, referred to setting the object you didn't click to be the child of the parent you did click on.
The camera should be an orthographic camera; using a perspective camera will cause the dragging to not align with where you think it should be.
In order to make the dragging work, I created a quad that was used as the 'background' to the 2D scene, and put that on a new layer called 'background'. Then setup the layermask field to only use the background layer.
Create and setup a material for the line renderer, (I'm using a Particles/Additive shader for the above example), and for the parameters of the line renderer I'm using Start Width: 0.75, End Width: 0, and make sure Use World Space is ticked.
Explanation
Firstly setup the otherSphere field to be pointing to the other sphere in the scene. OnMouseDown and OnMouseUp toggle the mouseDown bool, that is used to determine if the line renderer should be updated. These are also used to turn on/off the line renderer, and set/remove the parent transform of the two spheres.
To get the position to be dragged to, I'm getting a ray based off of the mouse position on screen, using the method ScreenPointToRay. If you wanted to create add smoothing to this drag functionality, you should enable the if (...) else statement at the bottom, and set the lerpTime to a value (0.25 worked well for me).
Note; when you release the mouse, the parent is immediately set, as such both objects end up getting dragged, but the child will return to it's former position anyway.
[RequireComponent(typeof(LineRenderer))]
public class ConnectedSphere : MonoBehaviour
{
[SerializeField]
private Transform m_otherSphere;
[SerializeField]
private float m_lerpTime;
[SerializeField]
private LayerMask m_layerMask;
private LineRenderer m_lineRenderer;
private bool m_mouseDown;
private Vector3 m_position;
private RaycastHit m_hit;
public void Start()
{
m_lineRenderer = GetComponent<LineRenderer>();
m_lineRenderer.enabled = false;
m_position = transform.position;
}
public void OnMouseDown()
{
//Un-parent objects
transform.parent = null;
m_otherSphere.parent = null;
m_mouseDown = true;
m_lineRenderer.enabled = true;
}
public void OnMouseUp()
{
//Parent other object
m_otherSphere.parent = transform;
m_mouseDown = false;
m_lineRenderer.enabled = false;
}
public void Update()
{
//Update line renderer and target position whilst mouse down
if (m_mouseDown)
{
//Set line renderer
m_lineRenderer.SetPosition(0, transform.position);
m_lineRenderer.SetPosition(1, m_otherSphere.position);
//Get mouse world position
if (Physics.Raycast(Camera.main.ScreenPointToRay(Input.mousePosition), out m_hit, m_layerMask))
{
m_position.x = m_hit.point.x;
m_position.y = m_hit.point.y;
}
}
//Set position (2D world space)
//if (m_lerpTime == 0f)
transform.position = m_position;
//else
//transform.position = Vector3.Lerp(transform.position, m_position, Time.deltaTime / m_lerpTime);
}
}
Hope this helped someone.
