transform.position any suggestions?
I try convert SmoothFollow script from JavaScript to C#:
using UnityEngine;
using System.Collections;
public class Kamera : MonoBehaviour {
public Transform obiekt;
public float distance = 10.0f;
public float height = 10.0f;
public float heightDamping = 2.0f;
public float rotationDamping = 3.0f;
void LateUpdate() {
if (!obiekt)
return;
float wantedRotationAngle = obiekt.eulerAngles.y;
float wantedHeight = obiekt.position.y + height;
float currentRotationAngle = transform.eulerAngles.y;
float currentHeight = transform.position.y;
currentRotationAngle = Mathf.LerpAngle (currentRotationAngle, wantedRotationAngle, rotationDamping * Time.deltaTime);
currentHeight = Mathf.Lerp (currentHeight, wantedHeight, heightDamping * Time.deltaTime);
Quaternion currentRotation = Quaternion.Euler (0, currentRotationAngle, 0);
transform.position = obiekt.position;
transform.position -= currentRotation * Vector3.forward * distance;
transform.position.y = currentHeight;
transform.LookAt (obiekt.transform);
}
}
I have this error: Cannot modify a value type return value of `UnityEngine.Transform.position'. Consider storing the value in a temporary variable. The error concerns this line:
transform.position.y = currentHeight;
I don't know what's wrong
You need to take the position, modify it and put it back otherwise it will have no effect:
var pos = transform.position;
pos.y = currentHeight;
transform.position = pos;
both 'transform' and 'transform.position' are properties, not variables. So, when you do:
transform.position = obiekt.position
obiekt.position = transform.position
The code is actually doing something more like:
GetComponent<Transform>().SetPosition(obiekt.position)
obiekt.position = GetComponent<Transform>().GetPosition()
Since GetComponent<> can be expensive, you should really do code like:
Transform tx = transform;
Vector3 position = obiekt.position;
position -= currentRotation * Vector3.forward * distance;
position.y = currentHeight;
tx.position = position;
tx.LookAt (obiekt.transform);
