Question

我在单一视图应用程序中制作应用程序。这只是一个简单的迷宫游戏。我想阻止角色穿过墙壁，但我无法做到这一点（缺乏经验）。请有人帮忙，我真的很感激。我的代码如下。

COLOR.H

#import <UIKit/UIKit.h>

int CharacterMovementUp;
int CharacterMovementLeft;
BOOL CollideWithWalls;

@interface color : UIViewController{
    NSTimer *MovementTimer;

}
@property (strong, nonatomic) IBOutlet UIImageView *Character;
@property (strong, nonatomic) IBOutletCollection(UIImageView) NSArray *Walls;

-(IBAction)Start:(id)sender;
-(void)Movement;
-(void)Collision;

@end

COLOR.M

#import "color.h"

@interface color ()

@end

@implementation color

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
    UITouch *touch = [touches anyObject];
    CGPoint point = [touch locationInView:self.view];

    if ((point.y > 460) && (CollideWithWalls == NO)) {
        CharacterMovementUp = 7;
        CharacterMovementLeft = 0;
    }
    else if((point.y < 140) && (CollideWithWalls == NO)) {
        CharacterMovementUp = -7;
        CharacterMovementLeft = 0;
    }
    else if((point.x < 160) && (point.y < 463) && (point.y > 140) && (CollideWithWalls == NO)){
        CharacterMovementUp = 0;
        CharacterMovementLeft = -7;
    }
    else if((point.x > 160) && (point.y < 460) && (point.y > 140) && (CollideWithWalls == NO)){
        CharacterMovementUp = 0;
        CharacterMovementLeft = 7;
    }
}

-(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event{
    CharacterMovementUp = 0;
    CharacterMovementLeft = 0;

}

-(void)Movement{
    _Character.center = CGPointMake(_Character.center.x + CharacterMovementLeft, _Character.center.y + CharacterMovementUp);

}

-(IBAction)Start:(id)sender{
    MovementTimer = [NSTimer scheduledTimerWithTimeInterval:0.05 target:self selector:@selector(Movement) userInfo:nil repeats:YES];
}

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    CollideWithWalls = NO;
    [super viewDidLoad];
    // Do any additional setup after loading the view.
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}
