Question

我已经开始运行SneakyJoystick，但是我希望以特定的频率按平铺移动我的精灵图块...我对iphone编程和cocos2d都很新，所以我不知道整个SneakyJoystick的东西是如何工作的。我从一本书中得到了代码并再次获得：我只是希望我的精灵像瓷砖游戏中的魔方瓷砖一样移动......

-(void)initJoystickAndButtons {
    CGSize screenSize = [CCDirector sharedDirector].winSize;
    CGRect joystickBaseDimensions =
    CGRectMake(0, 0, 128.0f, 128.0f);
    CGRect jumpButtonDimensions =
    CGRectMake(0, 0, 64.0f, 64.0f);
    CGRect attackButtonDimensions =
    CGRectMake(0, 0, 64.0f, 64.0f);
    CGPoint joystickBasePosition;
    CGPoint jumpButtonPosition;
    CGPoint attackButtonPosition;
    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
        // The device is an iPad running iPhone 3.2 or later.
        CCLOG(@"Positioning Joystick and Buttons for iPad");
        joystickBasePosition = ccp(screenSize.width*0.0625f,screenSize.height*0.052f);
        jumpButtonPosition = ccp(screenSize.width*0.946f,screenSize.height*0.052f);
        attackButtonPosition = ccp(screenSize.width*0.947f,screenSize.height*0.169f);
    } else {
        // The device is an iPhone or iPod touch.
        CCLOG(@"Positioning Joystick and Buttons for iPhone");
        joystickBasePosition = ccp(screenSize.width*0.07f,
                                   screenSize.height*0.11f);
        jumpButtonPosition = ccp(screenSize.width*0.93f,
                                 screenSize.height*0.11f);
        attackButtonPosition = ccp(screenSize.width*0.93f,
                                   screenSize.height*0.35f);
    }

SneakyJoystickSkinnedBase *joystickBase = [[[SneakyJoystickSkinnedBase alloc] init] autorelease];
joystickBase.position = joystickBasePosition;
joystickBase.backgroundSprite =[CCSprite spriteWithFile:@"dpadDown.png"];
joystickBase.thumbSprite =[CCSprite spriteWithFile:@"joystickDown.png"];
joystickBase.joystick = [[SneakyJoystick alloc]initWithRect:joystickBaseDimensions];

leftJoystick = [joystickBase.joystick retain];
leftJoystick.isDPad = YES;
[self addChild:joystickBase];

SneakyButtonSkinnedBase *jumpButtonBase =[[[SneakyButtonSkinnedBase alloc] init] autorelease];
jumpButtonBase.position = jumpButtonPosition;
jumpButtonBase.defaultSprite =[CCSprite spriteWithFile:@"jumpUp.png"];
jumpButtonBase.activatedSprite =[CCSprite spriteWithFile:@"jumpDown.png"];
jumpButtonBase.pressSprite = [CCSprite spriteWithFile:@"jumpDown.png"];
jumpButtonBase.button = [[SneakyButton alloc]initWithRect:jumpButtonDimensions]; 
jumpButton = [jumpButtonBase.button retain];
jumpButton.isToggleable = NO;
[self addChild:jumpButtonBase];
SneakyButtonSkinnedBase *attackButtonBase =[[[SneakyButtonSkinnedBase alloc] init] autorelease];
attackButtonBase.position = attackButtonPosition;
attackButtonBase.defaultSprite = [CCSprite spriteWithFile:@"handUp.png"];
attackButtonBase.activatedSprite = [CCSprite spriteWithFile:@"handDown.png"];
attackButtonBase.pressSprite = [CCSprite spriteWithFile:@"handDown.png"];
attackButtonBase.button = [[SneakyButton alloc]initWithRect:attackButtonDimensions];
attackButton = [attackButtonBase.button retain];
attackButton.isToggleable = NO;
[self addChild:attackButtonBase];

Answer 1

我为我的游戏做了类似的事情。有很多步骤，不能详细说明。

首先您需要知道何时使用操纵杆。

第二次你需要插入操纵杆的方向。对于像口袋妖怪这样的游戏，您只需要检查上/下/右/左方向。可以访问操纵杆的度。简单地解释像＆＃34;如果度在-45到45之间，则意味着操纵杆主要面向右边＆＃34;等

第三次您必须取消操纵杆与播放器对象的链接。那个教程，在某个地方，让你链接它们，以便操纵杆将自动移动播放器。你必须撤消它。

第四在您的场景中的某个地方制作计划。计划将解释操纵杆方向（如果正在使用），并将对玩家进行CCMoveBy操作。如果操纵杆指向右侧并且地图的平铺大小为32，则CCMoveBy移动参数将为（32,0）。如果玩家已经在运行，请记住不要运行其他动作。

有很多细节和很多东西要擦亮。你最好尝试单独询问每件事而不是一次性拍摄所有东西。
