javafx大球吃小球代码

在JavaFX中实现"大球吃小球"的游戏通常会涉及到用户界面设计、事件处理和游戏逻辑等部分。以下是一个简化的代码示例，展示了如何创建基本的场景和控制球体的行为：

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.layout.Pane;
import javafx.scene.paint.Color;
import javafx.scene.shape.Circle;
import javafx.stage.Stage;

public class PacmanGame extends Application {
    private static final int SIZE = 800;
    private Circle pacman, ghost;
    private double pacManSpeed = 2.0;
    private double ghostSpeed = 1.0;

    @Override
    public void start(Stage primaryStage) {
        primaryStage.setTitle("Pacman Game");
        primaryStage.setScene(createScene());
        primaryStage.show();
    }

    private Scene createScene() {
        Pane pane = new Pane();
        pane.setWidth(SIZE);
        pane.setHeight(SIZE);
        pane.setStyle("-fx-background-color: #222222;");

        pacman = new Circle(20, Color.WHITE, 10);
        pacman.setTranslateX(Math.random() * SIZE);
        pacman.setTranslateY(Math.random() * SIZE);
        pane.getChildren().add(pacman);

        // 假设有一个 Ghost 类来代表鬼魂，这里简化为一个圆形
        ghost = new Circle(20, Color.RED, 10);
        ghost.setTranslateX(Math.random() * (SIZE - 20));
        ghost.setTranslateY(Math.random() * (SIZE - 20));
        pane.getChildren().add(ghost);

        pane.setOnMousePressed(e -> movePacman(e.getX(), e.getY()));
        return new Scene(pane);
    }

    private void movePacman(double x, double y) {
        double dx = x - pacman.getCenterX();
        double dy = y - pacman.getCenterY();
        if (Math.pow(dx, 2) + Math.pow(dy, 2) < 100) { // 当接近鬼魂时，移动速度减慢
            pacManSpeed = 1.0;
        } else {
            pacManSpeed = 2.0;
        }
        pacman.setTranslateX(pacman.getTranslateX() + pacManSpeed * dx);
        pacman.setTranslateY(pacman.getTranslateY() + pacManSpeed * dy);
    }

    public static void main(String[] args) {
        launch(args);
    }
}
