Question L2 and R2 buttons are float -1 to 1

Dear community,

I finally got my PS4 controller working on the racing game I'm making, though, with some issues still.. As the input for the triggers (L2 and R2) are in float -1 (unpressed) to +1 (pressed).. My vehicle is responding to the non-pressed by driving in reverse..

Now I'm stuck on 2 questions, which my search online could not resolve..

1) How can I normalize the input for R2 to be between 0 and 1
2) How can I make the input for L2 to be between -1 and 0

Both triggers are used for the vertical input..

 

Hey! That's a simple math problem. You can use the following formula:

(value-min)/(max-min)

in you case that would be: value - (-1)/ 1 - (-1) = (value +1)/ 2

So, if you get a value of -0.8 from the input system, you would have: (-0.8+1)/2 = 0.2/2 = 0.1. So, turning -0.8 into a value between 0 and 1 (normalizing) gives you 0.1. Got it?

For your second question, you can just return -value.

Hope this helped!

* a code example (not optimized, written in a way that's easier for beginners to understand):

Code (CSharp):

1. public void R2()
2. {
3.       float value = controls.yourMap.YourR2Action.ReadValue<float>();
4.       return (value +1)/2;
5. }
6.  
7. public float L2()
8. {
9.       float value = controls.yourMap.YourL2Action.ReadValue<float>();
10.       return -((value +1)/2);
11. }
12.  

 

Thnks a lot for the quick response! I'm going to try and implement your script tomorrow and update accordingly!
