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());
