How to toggle a key for a car to go forward or backward?
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. this 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 this 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.
@Harshad$$anonymous$$ get$$anonymous$$eyDown didn't work the way I Wanted, I Have to $$anonymous$$eep pressing.. pressing..pressing.. pressing..pressing.. pressing.. on the "D" Button
I want to press only one so it goes forward unless I Want to switch to reverse gear and I Press the "R" Button ONLY ONCE!!
and thank you for helping me, I really appreciate it :)
Check this:
var direct : bool = true;
var reverse : bool = false;
void Update()
{
if(Input.Get$$anonymous$$eyDown($$anonymous$$eycode.D))
{
direct = true;
reverse = false;
}
if(Input.Get$$anonymous$$eyDown($$anonymous$$eyCode.R))
{
reverse = true;
direct = false;
}
if(direct)
{
goDirect();
}
else if(reverse)
{
goReverse();
}
}
It can also be done with only one variable:
var direct : bool = true;
void Update()
{
if(Input.Get$$anonymous$$eyDown($$anonymous$$eycode.D))
{
direct = true;
}
if(Input.Get$$anonymous$$eyDown($$anonymous$$eyCode.R))
{
direct = false;
}
if(direct)
{
goDirect();
}
else
{
goReverse();
}
}
@Harshad$$anonymous$$ I Did what you said, but unity gives me this error in the console "Assets/Scripts/Car$$anonymous$$ove.js(8,15): BCE0018: The name 'bool' does not denote a valid type ('not found')."
