I have a death animation already. I want a particle system particleRed to start along with the death animation. I have a private variable particleRed and I have initiated it in the awake function.
What should I do now?

I suggest making a empty game object prefab that holds the particle system. Then when you want to use the particle system, just instantiate the object. That is the easiest way i've found to go about it, and its rather versatile. Another way is, you could make the empty game object a child of your player, and then activate it when you want to use it. The second way isn't as ideal, but will get the job done too.
For the ParticleSystem component that you have added to the gameObject, set the enabled property to false by unchecking the enabled checkbox on the component.
Then in the KillPlayer function
particleRed.enabled = true;
Additionally you can ensure it is disabled in the Awake function by setting it to false.

I'm developing a 3d FPS game in Unity. At the moment I'm implementing a wall-running mechanic. The logic behind this is very simple - if player is pushing forward, and not grounded, and touching a wall, I constrain the Y/Z direction (but player can still run forward as I ignore the X direction though) and turn off gravity. It seems to work fine, a little bit clumsy but ok for me. Except, when the wall is left behind player is still able to run in mid-air until he runs out of inertia (here's the example: https://imgur.com/a/LtbWs9J). Here's the code:
using System.Collections.Generic;
using UnityEngine;
[RequireComponent(typeof(AudioSource))]
public class WallRunning : MonoBehaviour
{
public AudioClip audioClip;
private CharacterMovement cm;
private Rigidbody rb;
private bool isJumping;
public bool isWall;
private bool playAudio;
private AudioSource audioSource;
public float energyLimit = 3.5f;
private void Start()
{
//Get attached components so we can interact with them in our script.
cm = GetComponent<CharacterMovement>();
rb = GetComponent<Rigidbody>();
audioSource = GetComponent<AudioSource>();
}
private void FixedUpdate()
{
bool jumpPressed = Input.GetButtonDown("Jump");
float verticalAxis = Input.GetAxis("Vertical");
//Check if the controller is grounded.
if (cm.Grounded)
{
isJumping = false;
isWall = false;
}
//Has the jump button been pressed.
if (jumpPressed)
{
StartCoroutine(Jumping());
}
//If we are pushing forward, and not grounded, and touching a wall.
if (verticalAxis > 0 && isJumping && isWall)
{
StartCoroutine(Energy());
//We constrain the Y/Z direction to defy gravity and move off the wall.
//But we can still run forward as we ignore the X direction.
rb.useGravity = false;
rb.constraints = RigidbodyConstraints.FreezePositionY | RigidbodyConstraints.FreezePositionX | RigidbodyConstraints.FreezeRotation;
//We also telegraph to the player by playing a sound effect on contact.
if (audioClip != null && playAudio == true)
{
audioSource.PlayOneShot(audioClip);
//We block more audio being played while we are on the wall.
playAudio = false;
}
}
else
{
StopCoroutine(Energy());
//We need to make sure we can play audio again when touching the wall.
playAudio = true;
rb.useGravity = true;
rb.constraints = RigidbodyConstraints.FreezeRotation;
}
}
void OnCollisionEnter(Collision other)
{
//Are we touching a wall object?
if (other.gameObject.CompareTag("Walls"))
{
isWall = true;
}
}
void OnCollisionExit(Collision other)
{
//Did we stop touching the wall object?
if (!other.gameObject.CompareTag("Walls"))
{
isWall = false;
}
}
IEnumerator Jumping()
{
//Check for 5 frames after the jump button is pressed.
int frameCount = 0;
while (frameCount < 5)
{
frameCount++;
//Are we airbourne in those 5 frames?
if (!cm.Grounded)
{
isJumping = true;
}
yield return null;
}
}
IEnumerator Energy()
{
yield return new WaitForSeconds(energyLimit);
isWall = false;
}
}
Notice: walls have box colliders on them ("Is Trigger" checkbox is unchecked), and player has non-kinematic rigidbody and capsule collider attached. Walls aren't marked as "static" and assigned to Default layer, while player is assigned to the Player layer.
What am I doing wrong? I'm sure I screwed up with the code, but can't figure out the problem.
Replace
void OnCollisionExit(Collision other)
{
//Did we stop touching the wall object?
if (!other.gameObject.CompareTag("Walls"))
{
isWall = false;
}
}
With
void OnCollisionExit(Collision other)
{
//Did we stop touching the wall object?
if (other.gameObject.CompareTag("Walls"))
{
isWall = false;
}
}
I have created a NPC that follows the main player. When the player is in a certain range of the NPC, the NPC is supposed to walk, run, and attack based on the distance between the player and the NPC. The NPC has an Animator, box collider, Nav Mesh Agent, Enemy Animator And Enemy Controller Script attached. The settings are as follows,
My problem is that the NPC does not chase the player if there's some sort of grass or ferns on the terrain.
The NPC is set to run all types of terrain using Nav Mesh Agent, moreover the bake settings are like in the image. A video of the issue can be seen here.

I would appreciate very it if someone could help with such an issue!
EDIT: I forgot to add the grass settings, these are as follows. As you can see there are no colliders.
I am digging some more and apparently the only walkable area is as follows (not entire map), how can I adjust this?
Below is how I did:
Painted the terrain with all kinds of grasses I needed and trees.
Undone all the painted grasses and trees.
Baked the navigation mesh(Navmesh) onto the terrain.
Redone all the painted grasses and trees.
Boom! Work done. :)
Why Do grasses not walkable?
Grasses have been painted like trees hence they are carved during baking process as trees.
Trick:
You have to paint the grasses and all the trees needed, then you have to unpaint all the grasses exceptional for the trees. After that bake the terrain, and undone the process(pressing CTRL + Z several times) until you see the grasses repainted.
I'm trying to make a spring wall in my 2d platformer. However every way I've tried to move my character (addforce, transform.translate and even tried using the bouncy naterial) teleports my character rather then moving it. This doesn't happen with my controller script. I suspect something in my script is causing this interaction but I'm not sure exactly what. Here is my controller script. Any suggestions would be greatly appreciated :))

I'm making a game in which the player controls two different characters (each one has its own empty object with a camera as child), and switchs one or another by pressing the control key. The thing is, I'm trying to make a little transition between both characters cameras by using another camera, so it doesn't just teleports between one and another but I can't seem to do it. I tried with lerp but I don't know if I got it right, so I read and tried Vector3.MoveTowards but still couldn't do it. This is my code so far (the while is because a last-moment-braindead I had):
public class CameraController : MonoBehaviour
{
public Camera cam1;
public Camera cam2;
public Camera movingCamera;
public bool isCurrentPlayer;
public Transform target1;
public Transform target2;
public float speed = 0.2f;
void FixedUpdate()
{
float step = speed * Time.deltaTime;
if (Input.GetButtonDown("Control"))
{
if (isCurrentPlayer)
{
movingCamera.enabled = true;
cam2.enabled = false;
while (transform.position != target1.position)
{
transform.position = Vector3.MoveTowards(transform.position, target1.position, step);
}
if (transform.position == target1.transform.position)
{
movingCamera.enabled = false;
cam1.enabled = true;
}
isCurrentPlayer = false;
}
else if (!isCurrentPlayer)
{
movingCamera.enabled = true;
cam1.enabled = false;
while (transform.position != target2.position)
{
transform.position = Vector3.MoveTowards(transform.position, target2.position, step);
}
if (transform.position == target2.transform.position)
{
movingCamera.enabled = false;
cam2.enabled = true;
}
isCurrentPlayer = true;
}
}
}
I'm curious about two things. Why did you use FixedUpdate to manage your updates? This isn't physics code. Is there a particular reason you are using multiple cameras? If I may, I propose the following changes.
You can simply make use of the main camera instead of multiple cameras. Additionally, you can increase the number of player objects you can toggle through by using an array of player GameObjects, and by changing the input parameters to left control and right control, you can toggle between next player and previous player to navigate bi-directionally through the array of players.
Here's my example code that implements these changes (tested and works, though improvements can be made.)
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
// Attached to Main Camera
public class CameraController : MonoBehaviour {
// set manually in inspector
public GameObject[] players;
public float movementSpeed = 1.0f;
public float rotationSpeed = 1.0f;
private int currentPlayer;
private float startTime;
private float distanceToPlayer;
private Vector3 startPosition;
private Quaternion startOrientation;
// Use this for initialization
void Start () {
currentPlayer = 0;
ResetCamera();
}
// Update is called once per frame
void Update () {
float distanceCovered;
float rotationCovered;
float fractionTraveled;
// switch to previous
if (Input.GetButtonDown("left ctrl")) {
if (currentPlayer == 0) currentPlayer = players.Length - 1;
else currentPlayer--;
ResetCamera();
}
// switch to nextPlayer
if (Input.GetButtonDown("right ctrl")) {
if (currentPlayer == players.Length - 1) currentPlayer = 0;
else currentPlayer++;
ResetCamera();
}
// Keep moving camera
if (transform.position != players[currentPlayer].transform.position)
{
distanceCovered = (Time.time - startTime) * movementSpeed;
fractionTraveled = distanceCovered / distanceToPlayer;
rotationCovered = (Time.time - startTime) * rotationSpeed;
// Lerp to player position
transform.position = Vector3.Lerp(
startPosition,
players[currentPlayer].transform.position,
fractionTraveled
);
// match player orientation
transform.rotation = Quaternion.RotateTowards(
transform.rotation,
players[currentPlayer].transform.rotation,
rotationCovered
);
// Stop moving camera
} else {
// Match orientation
if (transform.rotation != players[currentPlayer].transform.rotation)
transform.rotation = players[currentPlayer].transform.rotation;
// Set parent transform to current player
transform.parent = players[currentPlayer].transform;
}
}
void ResetCamera() {
transform.parent = null;
startTime = Time.time;
startPosition = transform.position;
startOrientation = transform.rotation;
distanceToPlayer = Vector3.Distance(
transform.position,
players[currentPlayer].transform.position
);
}
}
Obviously the values would need to be tweaked, and the movement algorithm is pretty basic. Crude but function. You can also add player movement code into the camera, just make sure it points to players[currentPlayer] and it will work for each of your player objects without having to use additional scripts unless there is a reason to do so.
Feel free to use this code. Like I said, it works. However, should you choose to do so, it can easily be modified to function like your original code simply by removing the array and reinstating the individual GameObjects.
transform.position points to the position of CameraController game object. If you want to move movingCamera you probably want to use movingCamera.transform.position. Also keep in mind that in your script the MoveTowards() would only fire when you are pressing your "Control" button.
As memBrain said it would be the best practice to use only one camera for this - visually it would look the same.
The script should look something like this:

I would like to combine the First Person Controller from the Unity standard assets with the camera from the VROneSDK and VROneSDKHead, where the rotation of the character is controlled by the head tracking from the VROneSDK.
How can I do this with the SDK?
Unity's FPS controller uses the script MouseLook.cs to control the camera. The script is attached twice in this perfab. At the root object the script controls horizontal rotation and at the camera the script controls the vertical rotation.
Remove both scripts from the FPS controller.
Disable the main camera in the FPS controller. Attach the VROneSDK prefab to the FPS controller (as child of FPS controller) and copy the position and rotation values from the previous camera.
Create a new C# script VROneHeadLook.cs with the following content:
using UnityEngine;
using System.Collections;
public class VROneHeadLook : MonoBehaviour {
public bool useAngleX = true;
public bool useAngleY = true;
public bool useAngleZ = true;
public bool useRealHorizontalAngle = false;
public bool resetViewOnTouch = true;
private Quaternion initialRotation = Quaternion.identity;
private Quaternion currentRotation;
private static Vector3 gyroAngles; // original angles from gyro
private static Vector3 usedAngles; // converted into unity world coordinates
private int userSleepTimeOut; // original device SleepTimeOut setting
private bool gyroAvail = false;
// Use this for initialization
void Start () {
Input.compensateSensors = true;
}
// Update is called once per frame
void FixedUpdate () {
if (gyroAvail == false) {
if (Input.gyro.attitude.eulerAngles != Vector3.zero && Time.frameCount > 30) {
gyroAvail = true;
initialRotation = Input.gyro.attitude;
}
return; // early out
}
// reset origin on touch or not yet set origin
if(resetViewOnTouch && (Input.touchCount > 0))
initialRotation = Input.gyro.attitude;
// new rotation
currentRotation = Quaternion.Inverse(initialRotation)*Input.gyro.attitude;
gyroAngles = currentRotation.eulerAngles;
//usedAngles = Quaternion.Inverse (currentRotation).eulerAngles;
usedAngles = gyroAngles;
// reset single angle values
if (useAngleX == false)
usedAngles.x = 0f;
if (useAngleY == false)
usedAngles.y = 0f;
if (useAngleZ == false)
usedAngles.z = 0f;
if (useRealHorizontalAngle)
usedAngles.y *= -1;
transform.localRotation = Quaternion.Euler (new Vector3(-usedAngles.x, usedAngles.y, usedAngles.z));
}
void OnEnable() {
// sensor on
Input.gyro.enabled = true;
initialRotation = Quaternion.identity;
gyroAvail = false;
// store device sleep timeout setting
userSleepTimeOut = Screen.sleepTimeout;
// disable sleep timeout when app is running
Screen.sleepTimeout = SleepTimeout.NeverSleep;
}
void OnDisable() {
// restore original sleep timeout
Screen.sleepTimeout = userSleepTimeOut;
//sensor off
Input.gyro.enabled = false;
}
}
Attach this script to the FPS controller and the VROneSDK prefab. For the FPS controller set all script variables to false except 'Use Angle Y' which should be true.
For the script attached to the VROneSDK prefab set all script variables to false except 'Use Angle X'
