I’m trying to make a musical game,and right now trying to implement long notes(the ones you have to hold a button from the entire note,but the script i created dont work,it doenst show any error,just dont work.

    bool squee2 = false;	
    bool a = false;		
    	
    void Update(){
      if (Input.GetKey("up")&& a == true ){
        squee2 = true;
      }
      if (Input.GetKeyUp("up")){
        squee2 = false;;
        sistema.score -= 1;
      }
    }
    
    void OnTriggerEnter(Collider other) {	
      a = true;			
    }

    void OnTriggerExit(Collider other) {
      a = false;	
      if (squee2 == true) {
        // do stuff

Based on your reply, I think this logic could do the job: the variable pressed is set to true if the key was already pressed when the entering the trigger; if the key is released, pressed returns to false; when exiting the trigger, pressed is assigned to squee2. This way, squee2 will only become true if the key has been pressed during the whole trigger:

    bool pressed = false;
    bool squee2 = false;
    
    void OnTriggerEnter(Collider other) {
      // pressed tells if key was pressed when entering the trigger:			
      pressed = Input.GetKey("up"); 
    }

    void Update(){
      if (Input.GetKeyUp("up")){
        pressed = false; // detects if key was released
      }
    }

    void OnTriggerExit(Collider other) {
      // copy variable pressed to squee2 upon trigger exit:
      squee2 = pressed;	
    }

Thanks,it worked.
