Decrease players health depending on distance of enemy.

Questions & Answers

I’m making a 2D game in which your a small girl fighting of ghosts. I’ve written code that moves the ghosts toward the player using Vector3.Lerp which is working as I intended. I want to use Vector3.Distance to find how far away the enemies are away from my character, so far I’ve been able to get a value for the distance and that seems to be working. But I’m having problems with how to remove the players health or “Sanity” at a faster rate depending on how close the enemies are.

This is what I’ve come up with so far:
#pragma strict
var CharacterPos : Vector3;
var EnemyPos : Vector3;
static var Distance1 : Vector3;
var SanityValue: int;

function Update ()

{ 
	    var Distance1 : Transform;
        var dist = Vector3.Distance((CharacterMover.playerPos), (EnemyMovement2.EnemyPos));
     print ("Distance to other: " + dist);
       
      		 SanityRemover();  
     print (SanityValue); 
}

function SanityRemover() {

	if ((Distance1 > 4) & (Distance1 < 5)) {
		SanityValue -= 1 * Time.deltaTime; 
}
	else if ((Distance1 > 3) & (Distance1 < 4)) { 
		SanityValue -= 2 * Time.deltaTime;
}

	else if ((Distance1 > 2) & (Distance1 < 3)){
		SanityValue -= 3 * Time.deltaTime;
}
	else if ((Distance1 > 1) & (Distance1 < 2)) {
		SanityValue -= 4 * Time.deltaTime; 
}
	else if ((Distance1 > 0) & (Distance1 < 1)) {
		SanityValue -= 5 * Time.deltaTime;
}
	
}

I’m getting the following errors:

Operator ‘<’ cannot be used with a left hand side of type ‘UnityEngine.Vector3’ and a right hand side of type ‘int’.
Operator ‘>’ cannot be used with a left hand side of type ‘UnityEngine.Vector3’ and a right hand side of type ‘int’.

Also, is the way I’ve coded the if statements the best way of doing it?

Thanks in advance!

Try this:

#pragma strict

var SanityValue: float = 100;
private var dist : float;

function LateUpdate ()
{
	SanityRemover();
}
 
function SanityRemover() {
	dist = Vector3.Distance((CharacterMover.playerPos), (EnemyMovement2.EnemyPos));
	print ("Distance: " + dist);

	if (CheckWithinRange(dist, 4, 5)) {
		SanityValue -= 1 * Time.deltaTime; 
	}
	else if (CheckWithinRange(dist, 3, 4)) { 
		SanityValue -= 2 * Time.deltaTime;
	}
	else if (CheckWithinRange(dist, 2, 3)){
		SanityValue -= 3 * Time.deltaTime;
	}
	else if (CheckWithinRange(dist, 1, 2)) {
		SanityValue -= 4 * Time.deltaTime; 
	}
	else if (CheckWithinRange(dist, 0, 1)) {
		SanityValue -= 5 * Time.deltaTime;
	}

	print ("Sanity: " + SanityValue);
}

function CheckWithinRange(givenDist : float, min : int, max : int)
{
	if(givenDist > min && givenDist < max)
		return true;
	else
		return false;
}
