Pause Counter With Pause Button(s)

Questions & Answers
1

I’m creating a side-scrolling children’s game that teaches them the importance of conserving and recycling water.

In the game, there is a character called Chelsea who needs to collect 1000 milliliters of rain water to use in and around her home for later use, by simply running to and standing inside of an invisible box-collider - a spot in the game where some rain falls.

Chelsea will then need to run back and forth from this spot, emptying her bucket that she is using to collect the rain water, to a watering tank located on the other side of the playing field.

The obstacle of the game is to avoid another character by simply jumping over them or the amount of water she has collected in her bucket will be reset back to 0.

Everything is working fine, however when the pause is activated, the amount of water she has in her bucket will continue to add-up/collect, while she is inside of the box-collider.

The ‘Pause’ Script:

var skin:GUISkin;

var allowPause:boolean = true; // allow ESC to bring up pause menu
var startPaused:boolean = false; // start game with pause menu up

var legalwidth:int = 120;

var menutop:int=80;

private var gldepth = -0.5;
private var startTime = 0.1;

var mat:Material;

private var showtris:boolean;
private var showvtx:boolean;
private var showfpsgraph:boolean;

var publisher = "mywebsite.com.";
var srcValue = null;

var lowFPSColor = Color.red;
var highFPSColor = Color.green;

var lowFPS = 30;
var highFPS = 50;

var start:GameObject;

var goal:String = "Save as much water as you can!"; // goal statement displayed on pause menu

var statColor:Color = Color.yellow;
var hudColor:Color = Color.white;

// fill in the help text that is initially presented
var help:String[] = ["ESC or P - Pause Game"];

The ‘CatchWater’ Script:

private var soundTriggered = false;

public var waterCaught:int=0;

function OnTriggerStay(other : Collider){
	if(other.gameObject.tag=="Player"){
		waterCaught++;	
	}
	
	if(waterCaught >= 1000){		
		if (soundTriggered) return;
			audio.PlayOneShot(Sound);
				soundTriggered = true; 
	}
}

function OnGUI(){
	GUI.Label(Rect(60,314,250,100),(waterCaught.ToString())+ " mL") ; // Bucket	
}

function resetWaterCaught(){
	waterCaught=0;
}

The ‘DropWater’ Script:

private var touchingTank:boolean=false;

function Update(){
	if(touchingTank){
		
		if (Input.GetKey (KeyCode.Return)){
			
			tankLevel.updatetankLevel(GameObject.Find("Cloud/CloudHit").GetComponent(CatchWater).waterCaught);
			
			GameObject.Find("Cloud/CloudHit").GetComponent(CatchWater).waterCaught=0;
		}
	}			
}

function OnTriggerEnter(other : Collider){
	
	if(other.gameObject.tag=="Player"){
	touchingTank=true;
	}	
}

function OnTriggerExit(other : Collider){
	
	if(other.gameObject.tag=="Player"){
	touchingTank=false;	
	}	
}

How do I pause the counter that determines how much rain Chelsea has collected while she is within the box-collider - a spot in the game where some rain falls, when the pause button(s) are pressed?

The ‘CatchWater’ Script:

    var Sound : AudioClip;
    var GamePaused : bool;
    private var soundTriggered = false;
     
    public var waterCaught:int=0;
     
    function OnTriggerStay(other : Collider){
        if(other.gameObject.tag=="Player" && !GamePaused){ //Check if the game is paused before letting them collect water
            waterCaught++;  
        }
     
        if(waterCaught >= 1000){        
            if (soundTriggered) return;
                audio.PlayOneShot(Sound);
                    soundTriggered = true; 
        }
    }
     
    function OnGUI(){
        GUI.Label(Rect(60,314,250,100),(waterCaught.ToString())+ " mL") ; // Bucket    
    }
     
    function resetWaterCaught(){
        waterCaught=0;
    }

With that change now all you need to do is save the CatchWater script in the pause script with something like this:

var CatchScript : CatchWater;
	
	void Start () {
		CatchScript = GameObject.Find("ObjectWithCatchWaterScript").GetComponent<CatchWater>();
	}

Finally in the pause and unpause script change the bool GamePaused like this:

    CatchScript.GamePaused = true/false;

Hope this helps! Note that I use C# so I might have got a few things wrong in javascript but I think it’s all fine :stuck_out_tongue:
