Input Manager Question (GetButtonDown)

Hello,

New to Unity here, Im currently trying to adjust a script i purchased and was hoping someone can help me out here.

The current script contains "InputGetAxis" where if you press up or down it moves the car forward and backwards.

***************************************************************************************************************
void FixedUpdate()
{
if (!Enabled)
return;

#region UserInput
float vertical = Input.GetAxis("Vertical"); //Forward & Backward drive input
float horizontal = Input.GetAxis("Horizontal"); //Angular velocity control input
float space = Input.GetAxis("Jump"); //break control input
#endregion

if (vertical > 0)
CurrentEngineAcceleration = Acceleration * vertical;
else CurrentEngineAcceleration = (Acceleration * vertical) * BackwardAccelerationFactor;
*****************************************************************************************************************

What i need help is, is how do you change this code so that instead of pressing up and down on the keyboard, how do you change this so that when a player press a button with a NGUI button i created on the screen on the screen it moves the car forward and backwards?

Thanks for the help if you can

 

I think, you shold follow these steps:

1. Move variables vertical, horizontal and space from FixedUpdate() method to the class level (make them as fields).
2. Add them a setter methods or make them public
3. Create a class for getting input from NGUI buttons, add a reference to first class, and change vertical, horizontal and space fields via setter methods when NGUI buttons will be pressed.
