Problem with changing target of Camera.
Hi, I'm having a problem with "toggling" between targets of my camera. The camera is meant to follow a GameObject, and when certain conditions are filled (not completely ready yet on that part, still needs length and direction if-statements) it should go from my 3rd Person Controller to a car, and also hide the character. The problem is, that it won't toggle between targets, or it will toggle one time (if i choose the car in the beginning as target, i can toggle to the 3ps controller, however if i choose 3ps controller in the beginning, it won't toggle at all.
Example: Target: catamount, i start the game, i drive around, i press "e", camera starts following the 3ps controller and Debug.Logs "E-key pressed while in car". Example2: Target: 3ps controller, i start the game, i run around, i press "e", camera won't change and Debug.Logs "E-key pressed while in car".
Here's the code, it's C#:
using UnityEngine; using System.Collections;
public class HackNSlashCamera : MonoBehaviour { public Transform target; public float walkDistance; public float runDistance; public float height;
public float xSpeed = 250.0f; public float ySpeed = 120.0f; public float heightDamping = 2.0f; public float rotationDamping = 3.0f; public static bool goCar = false;
private Transform _myTransform;
private float x;
private float y;
private int pos;
private GameObject nextTarget;
void Awake() {
_myTransform = transform;
}
// Use this for initialization
void Start () {
if(target == null)
Debug.LogWarning("We do not have a target");
else {
CameraSetup();
}
}
void Update() {
if (goCar == false) {
if (Input.GetKeyDown (KeyCode.E)) {
Debug.Log("E-key pressed");
//var pos = target.transform.position;
//pos.x = 1000;
//target.transform.position = pos;
nextTarget = GameObject.Find("catamount");
target = nextTarget.transform;
goCar = true;
}
}
if (goCar == true) {
if (Input.GetKeyDown (KeyCode.E)) {
Debug.Log("E-key pressed while in car");
nextTarget = GameObject.Find("Character");
target = nextTarget.transform;
goCar = false;
}
}
}
void LateUpdate() {
if(Input.GetMouseButton(1) && target != null && goCar == false) {
Debug.Log("Right Button is down");
x += Input.GetAxis("Mouse X") * xSpeed * 0.02f;
y -= Input.GetAxis("Mouse Y") * ySpeed * 0.02f;
Quaternion rotation = Quaternion.Euler(y, x, 0);
Vector3 position = rotation * new Vector3(0.0f, 0.0f, -walkDistance) + target.position;
transform.rotation = rotation;
transform.position = position;
}
else {
x = 0;
y = 0;
// Calculate the current rotation angles
float wantedRotationAngle = target.eulerAngles.y;
float wantedHeight = target.position.y + height;
float currentRotationAngle = _myTransform.eulerAngles.y;
float currentHeight = _myTransform.position.y;
// Damp the rotation around the y-axis
currentRotationAngle = Mathf.LerpAngle (currentRotationAngle, wantedRotationAngle, rotationDamping * Time.deltaTime);
// Damp the height
currentHeight = Mathf.Lerp (currentHeight, wantedHeight, heightDamping * Time.deltaTime);
// Convert the angle into a rotation
Quaternion currentRotation = Quaternion.Euler (0, currentRotationAngle, 0);
// Set the position of the camera on the x-z plane to:
// distance meters behind the target
_myTransform.position = target.position;
_myTransform.position -= currentRotation * Vector3.forward * walkDistance;
// Set the height of the camera
_myTransform.position = new Vector3(_myTransform.position.x, currentHeight, _myTransform.position.z);
// Always look at the target
_myTransform.LookAt (target);
}
}
public void CameraSetup() {
_myTransform.position = new Vector3(target.position.x, target.position.y + height, target.position.z - walkDistance);
_myTransform.LookAt(target);
}
}
Help would be really appreciated (the main problem with the camera in first place, how to hide the character instead of sending it to x-positon 1000 is not necessary)
If-else problem in your Update. Change the second if(goCar==true) to just else.
Both ifs are triggering, so the 2nd always snaps it back to the player.
Oh... that's obvious. Still a little new to unity, and thought that the engine would convert the overflow if's automatically to "else ifs".
Thank you! ^^
I was just telling my guys, when a robot riding an N-dimensional cyborg chicken makes a PB&J, it still needs to watch the peanut butter doesn't $$anonymous$$r the bread. Past all the LookAt's and transform.up's, it's all just regular program$$anonymous$$g.
