WaterDisplay

WaterDisplay.java
The icon of the water will be stored in a list-waterImage , The timing refers to the scoreing system developed by the group 9

    public static ArrayList<Image> chickenImage = new ArrayList<>();

The listeners implemented here lookout for trigger events，Creates reusable drop of water ui styles and adds actors to the stage.

    public void create() {
        super.create();
        addActors();
        entity.getEvents().addListener("updateWater", this::updatePlayerTimerUI);
    }

Creates actors, add images into list, and positions them on the stage using a table.

private void addActors() {
        table = new Table();
        table.top().left();
        table.setFillParent(true);
        table.padTop(150f).padLeft(10f);

        //Add water image
        float clockSideLength = 30f;
        waterImage.add(new Image(ServiceLocator.getResourceService()
                .getAsset("images/water1.png", Texture.class)));
        waterImage.add(new Image(ServiceLocator.getResourceService()
                .getAsset("images/water1.png", Texture.class)));
        waterImage.add(new Image(ServiceLocator.getResourceService()
                .getAsset("images/water1.png", Texture.class)));
        waterImage.add(new Image(ServiceLocator.getResourceService()
                .getAsset("images/water1.png", Texture.class)));

add images into the screen

        table.add(waterImage.get(0)).size(clockSideLength).pad(3);
        table.add(waterImage.get(1)).size(clockSideLength).pad(3);
        table.add(waterImage.get(2)).size(clockSideLength).pad(3);
        table.add(waterImage.get(3)).size(clockSideLength).pad(3);
        stage.addActor(table);

Reduce water when time increase, and lookout for trigger event

public void update() {
        super.update();
        int minutes = countTime.getMinutes();
        int seconds = countTime.getSeconds();
        int dis = (minutes*60+seconds)/2;
        if(dis> countWaterSystem.getTimer()){
            countWaterSystem.setDifference(1);
            countWaterSystem.setTimer(dis);
        }else {
            countWaterSystem.setDifference(0);
        }
        //update the water regularly
        entity.getEvents().trigger("updateWater", countWaterSystem.getDifference());
    }
    }

Updates the Chicken ui time by time increase.

            if(waterImage.size() > 0){
                table.reset();
                table.top().left();
                table.setFillParent(true);
                table.padTop(150f).padLeft(10f);
                waterImage.remove(waterImage.size() - 1);
                for (Image ima: waterImage) {
                    table.add(ima).size(30f).pad(3);
                }
            }
        }
    }

remove chickenImage by useing a for loop

    public void dispose() {
        super.dispose();
        timeLabel.remove();
        for (int i = 0; i < waterImage.size(); ++i){
            waterImage.remove(i);
        }
    }

function

Add/remove a image, value =1: add a waterimage; value = -1 :remove a water image

    public static void addOrRemoveImage(int value){
        if(value == 1){
            if(chickenImage.size() < 4){
                chickenImage.add(new Image(ServiceLocator.getResourceService()
                        .getAsset("images/water1.png", Texture.class)));
                table.add(chickenImage.get(images/water1.size() - 1)).size(30f).pad(3);
            }
        }else if(value == -1){
            if(chickenImage.size() > 0){
                table.removeActor(chickenImage.get(chickenImage.size() - 1));
            }
        }
    }

if there is no images in the list, it will return a true

    public static boolean isThirst(){
        return waterImage.size() <= 0;;
    }

add a water icon on main screen when player pick up a target(item)

        public void increaseWater(Entity target) {
        if (target != null) {
            if (WaterDisplay.waterImage.size() < 4) {
                WaterDisplay.addOrRemoveImage(1);
            }

Sprin3---thirst

if water icon count less than 0, then it will be into that codes to run. it reduce player health value.

    public void updatePlayerHealth(int dis){
        if(dis == 2){
            if(waterImage.size() <= 0){
                //if water icon count less than 0, then it will be into that codes to run. it reduce player health value.
                //reduce player health value
                MainGameScreen.players.getComponent(CombatStatsComponent.class).setHealth(
                        MainGameScreen.players.getComponent(CombatStatsComponent.class).getHealth() - 1
                );
            }
        }
    }
