SneakyJoystick - 由某些點/瓷磚的運動

Question

我有SneakyJoystick啓動並運行，但我想要移動我的精靈瓷磚的瓷磚在一定的頻率...我對iPhone編程和cocos2d很新，所以我不完全知道整個SneakyJoystick thingy是如何工作的。 我從一本書的代碼，並再次：我只是希望我的精靈一樣在遊戲口袋妖怪瓦琉璃磚移動...

-(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");

     attackButtonPosition = ccp(screenSize.width*0.93f, 
            screenSize.height*0.35f); 
    }

Answer 1

我爲我的遊戲類似的東西。有很多步驟，不能深入細節。

第一個您需要知道何時使用操縱桿。

第二個您需要插入操縱桿的方向。對於像口袋妖怪這樣的遊戲，你只需要檢查上/下/右/左方向。可以訪問操縱桿的度數。簡單地解釋度，如「如果是度之間-45到45，這意味着操縱桿主要是向右」等

三，你將不得不從您的播放器對象斷開鏈接的操縱桿。這個教程在某個地方讓你連接它們兩個，這樣操縱桿就會自動移動播放器。你必須撤消這個。

第四個在你的場景中的某個地方組成一個時間表。時間表將解釋遊戲杆的方向（如果它正在使用），並且將對玩家運行一個CCMoveBy動作。如果操縱桿指向右側並且地圖的圖塊大小爲32，那麼CCMoveBy移動參數將爲（32,0）。如果玩家已經在運行一個，請記住不要執行其他操作。

有很多細節和很多波蘭語。你最好試着單獨詢問每一件事，而不是一件事。
