How to toggle a key for a car to go forward or backward?

Question

I Have two functions, one is when I want my car to go forward, and the other to go backward, If I Want to switch between them, I Keep Pressing on the "D" key. t$$anonymous$$s is my code if(Input.GetKey(KeyCode.D)){ var direct = true; } if(Input.GetKey(KeyCode.R)){ var reverse = true; } if(direct){ goDirect(); } else if(reverse) { goReverse(); };

I Don't want to keep holding the "D" or The "R" button to make the car go in whatever direction "Continue doing the same function as long as I'm holding the key", I want to press once, I Pressed "D" so direct = true and the car continues to go forward unless I Press the "R" Button, It's like ON/OFF Button ?

Instead of Input.GetKey use Input.GetKeyDown. Also don't declare direct inside if loop, put it outside any loop.

 // Declare t$$anonymous$$s variable above any method
 var direct : bool;

 if(Input.GetKeyDown(KeyCode.D)){
     direct = true;
 }
 
 if(Input.GetKeyDown(KeyCode.R)){
     reverse = true;
 }

It will work like you want.
