Question by phillipe · Nov 28, 2012 at 12:50 PM · speedfollowincrease

Make enemy's speed faster through time

Hello guys! I found this script from one of the questions here and it's a simple one to let a game object follow your character:

 var target : Transform; //the enemy's target
 var moveSpeed = 3; //move speed
 var rotationSpeed = 3; //speed of turning
 
 var myTransform : Transform; //current transform data of this enemy
 
 function Awake()
 {
     myTransform = transform; //cache transform data for easy access/preformance
 }
 
 function Start()
 {
      target = GameObject.FindWithTag("Player").transform; //target the player
 
 }
 
 function Update () {
     //rotate to look at the player
     myTransform.rotation = Quaternion.Slerp(myTransform.rotation,
     Quaternion.LookRotation(target.position - myTransform.position), rotationSpeed*Time.deltaTime);
 
     //move towards the player
     myTransform.position += myTransform.forward * moveSpeed * Time.deltaTime;
 
 
 }

What I want though is to make the follower's move speed increase by "1" after every 30 minutes. Is it possible? Are there other better scripts than the one above? Thanks.

Add a variable that sets a time limit, and then compare this time limit to the elapsed time since the game started. (60 seconds x 30 minutes = 1800). And when that time limit is reached add to the speed variable, and add another 1800 to your time limit to make it wait another 30 minutes.

Someting like this:

     private var timeLimit = 1800.0f;
     
     function Update () {
     
     // your code here...
     
     if(Time.time >= timeLimit)
     {
      // Add 1 to the moveSpeed...
      moveSpeed += 1;
      // make it wait another 30 mins...
      timeLimit += 1800.0;
     }
     
      // more code here...
     }

Good luck!

Wow, took me couple of $$anonymous$$utes to figure it out. Not really a programmer, but I just noticed that you missed the variable name: "timelimit" ins$$anonymous$$d of using "timeLimit". Works fine, cheers!
