cocos2d-x 橫板游戲觸屏人物和背景移動方法1

本文轉載自查看原文 2013-01-22 23:48 4782 cocos2d-x/ 橫板游戲角色移動

大多橫板游戲主角的移動都是有背景一起在移動的，不單單是主角在動。當主角的位置離地圖的左端距離小於屏幕寬度的一半或者主角離地圖最右端的距離小於屏幕寬度的一半時，觸屏之后就人物在移動，背景沒有動，當主角位於這端中間的位置時，觸屏之后主角移動的同時，背景也在往主角反方向移動，一旦當主角移動到兩端的內邊界時，背景就停止移動，只主角移動。

這段代碼放到這里做個備份，不是最終版，而且也不是性能最高的解決辦法，

當主角走到兩端時，背景偶爾會走多了出線黑邊，

功能：每次點擊屏幕之后，主角停止當前的動作，走到觸屏的那個點然后停下來。
