手把手一步一步教你使用Java开发一个大型街机动作闯关类游戏15

攻击范围

AttackAbleObject.java

package character;

import sprite.Transform;

import java.awt.*;
import java.awt.geom.AffineTransform;

public abstract class AttackAbleObject extends GameObject{
    private Transform _transform;

    private int _cx1;
    private int _cx2;
    private int _cy1;
    private int _cy2;
    
    public AttackAbleObject(Transform trans,
                            int hurt_x, int hurt_y, int hurtscale_x, int hurtscale_y, int hitoffset_x1,
                            int hitoffset_y1, int hitoffset_x2, int hitoffset_y2) {
        super(trans,hurt_x,hurt_y,hurtscale_x, hurtscale_y);
        _transform = trans;
        this.setHitBoxOffsets(hitoffset_x1,hitoffset_y1,hitoffset_x2,hitoffset_y2);
    }

    public Shape getHitBox(){
        AffineTransform as = new AffineTransform();
        as.setTransform(_transform.getTransform());
        return as.createTransformedShape(new Rectangle(_cx1,_cy1,_cx2,_cy2));
    }
    public void setHitBoxOffsets(int x1,int y1, int x2, int y2){
        _cx1 = x1;
        _cx2 = x2;
        _cy1 = y1;
        _cy2 = y2;
    }
}

Player.java继承AttackAbleObject，在构造函数中传入player的攻击范围参数（最后4个参数）

public class Player extends AttackAbleObject{
    

    
    public Player(Animator animator, int hurtx, int hurty, int hurtscale_x, int hurtscale_y
            , int hitoffset_x1, int hitoffset_y1, int hitoffset_x2, int hitoffset_y2){
        super(animator,hurtx,hurty,hurtscale_x,hurtscale_y
                ,hitoffset_x1,hitoffset_y1,hitoffset_x2,hitoffset_y2);
}

最后GameApp.java中，player的构造方式改为如下：

_player = new Player(animator,60,44,18,98
                    ,65,60,50,11);

我们可以通过以下调用以下方法，可视化player的攻击范围

g.draw(_player.getHitBox());
