Question by Abacab · May 16, 2015 at 04:07 PM · c#velocitycar

Turbo Functionality

Hello!

I'd like to add Crash Team Racing like turbo power-ups to my game, but I don't know how to exactly do that. I'd like the turbo to instantly make the car go even higher than normal top speed, but then slow down to top speed after a second.

Should I use rigidbody.velocity or something else?

Thanks in advance!

Increase the wheelcollider(if you use them) torque to something higher than the topspeed torque, then change it back to the normal torque.

That doesn't instantly increase the speed to a set amount. :)

Currently I have it set like this:

 void Turbo ()
     {
         if (PlayerPrefs.GetInt ("Selected Car") == 1) {
             topSpeed = 650;
         } else if (PlayerPrefs.GetInt ("Selected Car") == 2) {
             topSpeed = 665;
         } else if (PlayerPrefs.GetInt ("Selected Car") == 3) {                
             topSpeed = 680;
         } else if (PlayerPrefs.GetInt ("Selected Car") == 4) {                            
             topSpeed = 680;
         } else if (PlayerPrefs.GetInt ("Selected Car") == 5) {
             topSpeed = 695;
         } else if (PlayerPrefs.GetInt ("Selected Car") == 6) {
             topSpeed = 695;
         }
         motorInputTouch = 1;
         gasOn = true;
 
 
         wheelBR.motorTorque = TurboTorque * motorInputTouch;
         wheelBL.motorTorque = TurboTorque * motorInputTouch;
 
         Invoke ("TurboEnds", 1);
     }

I don't think you can make it instant without actually setting the rigidbody velocity. Try making the torque increase much higher (so it is a faster acceleration) and limiting the velocity by setting the torque to zero if you go above a certain velocity.
