Change Camera Position

Questions & Answers
1

I am making a car game in Unity. I want the user to be able to change the camera position.
My current code gives back very weird values, that doesn’t make any sense.

This is my code:

#pragma strict
var currentAng = 2;

function Update () {
	if(currentAng > 3){
		currentAng = 1;
	}
	if (Input.GetKeyDown ("c")){
		print ("C key was pressed");
		Move();
	}
}
function Move () {
	if(currentAng == 1){
		transform.position = Vector3.Lerp(this.transform.position, new Vector3(7,5367,-16293), 0.2);
	}
	if(currentAng == 2){
		transform.position = Vector3.Lerp(this.transform.position, new Vector3(-7,3056,5861), 0.2);
	}
	if(currentAng == 3){
		transform.position = Vector3.Lerp(this.transform.position, new Vector3(-964,3056,656), 0.2);
	}
	currentAng++;
}
2

As defined here, Vector3.Lerp interpolates between the given points by the fraction given in the 3rd parameter. As shown in the example, if we want to “animate” a transition, Lerp should be called inside the Update method instead of doing it once when a key is pressed.

Here’s the modified script with other suggestions too

#pragma strict
var currentAng:int = 2; // define var types for better coding experience ;)
var startPos:Vector3;
var endPos:Vector3;
var speed:float = 1;
var time:float = 0;

function Start () 
{
// call Move in the beginning to initialize startPos and endPos
	Move();
}

function Update () 
{
	time += Time.deltaTime;
	
	// calculate how many % of the distance is traveled base on set speed
	var pctOfDistanceTraveled = time * speed;
	
	// cap the traveled distance to be [0, 1]
	if (pctOfDistanceTraveled > 1) {
		pctOfDistanceTraveled = 1;
	}

// move this object to a position where it has started from startPos and had traveled "pctOfDistanceTraveled" of the distanve to endPos 
   	transform.position = Vector3.Lerp(startPos, endPos, pctOfDistanceTraveled);
    
    if (Input.GetKeyDown ("c")){
       print ("C key was pressed");
       Move();
    }
}

function Move () 
{
	// reset move timer
	time = 0;

    currentAng++;
    if(currentAng > 3) // if currentAng is changed only in Move, it only needs to be capped here (not every Update)
    {
       currentAng = 1;
    }
    
    // always start the moving from where we were when Move was called
	startPos = this.transform.position;
    
    // currentAng can be only one of these values at a time, hence "else if"
    if(currentAng == 1){
       // mark down where we want the transition to end up
       endPos = new Vector3(7,5367,-16293);
    }
    else if(currentAng == 2){
      	endPos = new Vector3(-7,3056,5861);
    }
    else if(currentAng == 3){
      	endPos = new Vector3(-964,3056,656);
    }
}
