Problems with Vector3's and Vector3.Distance

Questions & Answers
1

so i found a cool script on youtube that makes a good looking 3rd person camera script. the script is js, but i am trying to teach myself C# so i translated it with the help of the scripting reference but i ran into a few problems.

my script:
using UnityEngine;
using System.Collections;

public class camFollow : MonoBehaviour {

	public LayerMask mask;
	public Transform target;
	public float height;
	public float distance;
	public float x;
	public float y;
	public float yMin;
	public float yMax;
	
	void Update () {
		x += 3 * Input.GetAxis ("Mouse X");
		y += 3 * Input.GetAxis ("Mouse Y");
		if(y > yMax){
			y = yMax;
		}
		if(y <yMin){
			y = yMin;
		}
		
		Quaternion rotation = Quaternion.Euler (y,x, 0);
		Vector3 pos = rotation * new Vector3(0, height, -distance) + target.position;
		
		transform.rotation = rotation;
		transform.position = pos;
		
		RaycastHit hit;
		if(Physics.Linecast(target.position, transform.position, out hit, mask)){
			float temDistance =   Vector3.Distance(target.position, hit.point);
			pos = rotation *  Vector3(0, height, -tempDistance) + target.position;
			transform.position = pos;
		}
	}
}

with this i got this error:
Assets/camFollow.cs(34,43): error CS0119: Expression denotes a type', where a variable’, value' or method group’ was expected

i got this error before and i found a solution on the internet, so i used the same method to fix it and i changed line 34 to:

pos = rotation * new Vector3(0, height, -tempDistance) + target.position;

but then i got these errors:

Assets/camFollow.cs(34,66): error CS0103: The name `tempDistance’ does not exist in the current context

Assets/camFollow.cs(34,80): error CS1502: The best overloaded method match for `UnityEngine.Vector3.Vector3(float, float, float)’ has some invalid arguments

Assets/camFollow.cs(34,80): error CS1503: Argument #3' cannot convert object’ expression to type `float’

any idea what i did wrong?

the first error is becuase you created tempDistnace not tempDistance

the second error is because 0 isn’t a float and vectors are made from floats.

you can fix that by coverting it to a float

0 isnt a float but

0f

is
the f means i’m a float.
the third error is a continuation of the first really.
