noob here
So I am using two push buttons (connected to an Arduino Uno) as an input to my game. The player has to push down both buttons at the same time for the character to move in the game. I want the player to hold down the buttons for a different amount of time in each level. I have a working Arduino and a working Unity timer and player script, but am not able to get the code to do what I want. What I basically want is that only when the player presses the buttons down, does the timer start counting down. Right now, the timer starts as soon as the scene begins. I know that I somehow have to reference the timer script to the button object, I have tried this but it still doesn't work. Note that the timer UI does have a Timer tag on it. I have also referenced the Player Controller script in the Timer script. Right now, the timer just doesn't count down at all. Please help Please assist in any manner
The Timer script:
using UnityEngine;
using System.Collections;
using UnityEngine.UI;
using UnityEngine.SceneManagement;
public class Timer : MonoBehaviour
{
//int startTime = 0;
public bool buttonPressed = false;
public int timeLeft;
public Text countdownText;
GameObject Character;
void Awake()
{
Character = GameObject.FindWithTag("Player");
}
// Use this for initialization
public void Start()
{
//StartCoroutine("LoseTime");
BeginTimer();
}
// Update is called once per frame
void Update()
{
countdownText.text = ("Time Left = " + timeLeft);
if (timeLeft <= 0)
{
//StopCoroutine("LoseTime");
//countdownText.text = "Times Up!";
Invoke("ChangeLevel", 0.1f);
}
}
public void BeginTimer()
{
Character.GetComponent<PlayerController>().Update();
if (buttonPressed == true )
{
StartCoroutine("LoseTime");
}
}
IEnumerator LoseTime()
{
while (true)
{
yield return new WaitForSeconds(1);
timeLeft--;
}
}
void ChangeLevel()
{
SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex + 1);
}
}
The Player controller script:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using System.IO.Ports;
public class PlayerController : MonoBehaviour
{
SerialPort sp = new SerialPort("\\\\.\\COM4", 9600);
//player == GameObject.FindWithTag("Player").GetComponent<>();
public float Speed;
public Vector2 height;
public float xMin, xMax, yMin, yMax;
public bool buttonPressed = false;
GameObject Character;
void Awake()
{
Character = GameObject.FindWithTag("Player");
}
void Start()
{
if (!sp.IsOpen)
{ // If the erial port is not open
sp.Open(); // Open
}
sp.ReadTimeout = 1; // Timeout for reading
}
public void Update()
{
if (sp.IsOpen)
{ // Check to see if the serial port is open
try
{
string value = sp.ReadLine();//To("Button"); //Read the information
int button = int.Parse(value);
//float amount = float.Parse(value);
//transform.Translate(Speed * Time.deltaTime, 0f, 0f); //walk
if (button == 0) //*Input.GetKeyDown(KeyCode.Space*/) //jump
{
buttonPressed = true;
Character.GetComponent<Rigidbody2D>().AddForce(height, ForceMode2D.Impulse);
Character.GetComponent<Rigidbody2D>().position = new Vector3
(
Mathf.Clamp(GetComponent<Rigidbody2D>().position.x, xMin, xMax),
Mathf.Clamp(GetComponent<Rigidbody2D>().position.y, yMin, yMax)
);
Timer tmr = GameObject.Find("Timer").GetComponent<Timer>();
tmr.BeginTimer();
}
}
catch (System.Exception)
{
}
}
void ApplicationQuit()
{
if (sp != null)
{
{
sp.Close();
}
}
}
}
}
Any tips and assistance will be appreciated
