Fooddisplay

FoodDisplay.java
The icon of the food will be stored in a list, The timing refers to the scoreing system developed by the group 9

public class FoodDisplay extends UIComponent {
    static Table table;
    private Label timeLabel;
    private final CountFoodSystem countFoodSystem = new CountFoodSystem();
    private final ScoringSystemV1 timeCount = new ScoringSystemV1();
    public static ArrayList<Image> chickenImage = new ArrayList<>();
    private int chickenCurrent = 4;
        

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

    @Override
    public void create() {
        super.create();
        addActors();
        entity.getEvents().addListener("updateChicken", 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(100f).padLeft(10f);

        float clockSideLength = 30f;
        chickenImage.add(new Image(ServiceLocator.getResourceService()
                .getAsset("images/food1.png", Texture.class)));
        chickenImage.add(new Image(ServiceLocator.getResourceService()
                .getAsset("images/food1.png", Texture.class)));
        chickenImage.add(new Image(ServiceLocator.getResourceService()
                .getAsset("images/food1.png", Texture.class)));
        chickenImage.add(new Image(ServiceLocator.getResourceService()
                .getAsset("images/food1.png", Texture.class)));
        

add images into the screen

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

Reduce food when time increase, and lookout for trigger event

    public void update() {
        super.update();
        int minutes = timeCount.getMinutes();
        int seconds = timeCount.getSeconds();
        int dis = (minutes * 60 + seconds) / 3;
        if(dis > countFoodSystem.getTimer()){
            countFoodSystem.setDifference(1);
            countFoodSystem.setTimer(dis);
        }else {
            countFoodSystem.setDifference(0);
        }
        //update the food regularly
        entity.getEvents().trigger("updateChicken", countFoodSystem.getDifference());
    }  

Updates the Chicken ui time by time increase.

    public void updatePlayerTimerUI(int dis) {
        if(dis > 0){
            if(chickenImage.size() > 0){
                table.reset();
                table.top().left();
                table.setFillParent(true);
                table.padTop(100f).padLeft(10f);
                chickenImage.remove(chickenImage.size() - 1);
                for (Image ima: chickenImage) {
                    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 < chickenImage.size(); ++i){
            chickenImage.remove(i);
        }
    }   

function

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

    public static void addOrRemoveImage(int value){
        if(value == 1){
            if(chickenImage.size() < 4){
                chickenImage.add(new Image(ServiceLocator.getResourceService()
                        .getAsset("images/food1.png", Texture.class)));
                table.add(chickenImage.get(chickenImage.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 isHunger(){
        return chickenImage.size() <= 0;
    }

add a food image in the main screen when player pick up a item

      public void increaseFood(Entity target) {
        if (target != null) {
            if (FoodDisplay.chickenImage.size() < 4) {
                FoodDisplay.addOrRemoveImage(1);
            }
        }
    }

Sprin4---hunger

if foof icon count less than 0, then it will be into that codes to run. it increase player health per second.

    public void updatePlayerHealth(int dis){
        int health = MainGameScreen.players.getComponent(CombatStatsComponent.class).getHealth();
        if(dis == 2){
            if(foodImage.size() <= 0 && health <100){
                //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
                );
            }
        }
    }
