本文实例为大家分享了unity3d实现flappy bird的具体代码，供大家参考，具体内容如下
一、小鸟
在游戏中，小鸟并不做水平位移，而是通过障碍物的移动让小鸟有水平运动的感觉，小鸟只需要对鼠标的点击调整竖直加速度就可以了，同时加上水平旋转模仿原版的flappybird的运动。同时，还要对竖直位置进行判断，否则游戏不能正常结束。
这里贴上小鸟上附加的脚本代码
player.cs

二、障碍物
障碍物只要定时产生，随机设定偏移量，然后添加向左运动的速度就行了，同时要设定自动销毁的时间，回收障碍物，否则内存占用会越来越大。
这里用了三个脚本，分别是上下障碍物和障碍物生成脚本。附加到一个空物体上就行了。

此外还有分数显示，最佳分数显示，音效等等，都是细节。
