打飞机

项目介绍：

之前看到过几次，感觉这小游戏很不错，今天写出来给大家分享一下。游戏很简单，初学者也能学会的。

#import "ViewController.h"
#define kWindowWidth                        [[UIScreen mainScreen] bounds].size.width
#define kWindowHeight                       [[UIScreen mainScreen] bounds].size.height

@interface ViewController ()
{
    NSInteger floatWeight;
    NSTimer *timer;
    NSInteger fen;
}
@property (nonatomic ,strong) UIImageView *bgImg1;
@property (nonatomic ,strong) UIImageView *bgImg2;
@property (nonatomic ,strong) UIImageView *myPlane;
@property (nonatomic ,strong) NSMutableArray *diJiArray;
@property (nonatomic ,strong) NSMutableArray *ziDanArray;
@property (nonatomic ,strong) UIImageView *baozha;
@property (nonatomic ,strong) NSMutableArray *baozhaArray;
@property (nonatomic ,strong) UILabel *fenLab;

@end

内容主要围绕几个定时器来搞得。

    fen = 0;
    [self.view addSubview:self.bgImg1];
    [self.view addSubview:self.bgImg2];
    [self.view addSubview:self.myPlane];
    [self.view addSubview:self.baozha];
    [self.view addSubview:self.fenLab];
    //创建控制地图移动的定时器
    [NSTimer scheduledTimerWithTimeInterval:.05 target:self selector:@selector(mapMove) userInfo:nil repeats:YES];
    //创建找敌机的定时器
    [NSTimer scheduledTimerWithTimeInterval:.2 target:self selector:@selector(findDiJi) userInfo:nil repeats:YES];
    //创建控制敌机下落的定时器
    [NSTimer scheduledTimerWithTimeInterval:.05 target:self selector:@selector(downDiJi) userInfo:nil repeats:YES];
    //创建找子弹的定时器
    [NSTimer scheduledTimerWithTimeInterval:.1 target:self selector:@selector(findZiDan) userInfo:nil repeats:YES];
    //发射子弹
    [NSTimer scheduledTimerWithTimeInterval:0.05 target:self selector:@selector(fireZiDan) userInfo:nil repeats:YES];
    //创建爆炸的定时器
    timer =   [NSTimer scheduledTimerWithTimeInterval:0.1 target:self selector:@selector(baoZha) userInfo:nil repeats:YES];
