Question by AndreasX12 · Mar 25, 2013 at 09:01 AM · speedcaracceleration

Void loop?

Hello, I'm trying to make a car script, and i'm currently working on the acceleration script. The problem is, that I would like the car to slowly/smoothly accelerate, so that it doesn't go from 100 km/h to 0 instantly, when you release the forward button :-) Is it possible that I can make the script add maybe 10 to the speed value every second?

Thanks Andreas.

Well, can't give exact code without knowing what data types you're using, but you'll want something along the lines of:

 void Update()
 {
     if(Input.GetKey(KeyCode.Space))
         speed += 10 * Time.deltaTime;
 }

to increase the speed 10 units per second while a button is held.

Add to your speed using MoveTowards

   if(Input.GetKey("w"))
   {
       speed = Mathf.MoveTowards(speed, maxSpeed, accelerationPerSecond * Time.deltaTime);
   }

Thank you :-) Works perfectly, how can I make the car brake (S), since that should be faster than accelerating? :-)

I kinda figured it out using deccelerationPerSecond and so on :-) Thanks for your help :-)
