小雲盒子控制器，無法輸入聲音，可能解法

小雲盒子控制器，

常常放一段時間之後，

就無法使用由控制器聲音輸入的功能，

此時往往只要小雲盒子重開機就好。

後來懷疑單純是藍芽控制器失去藍芽連線，

所以就選藍芽->重新連接 控制器的裝置，

果然OK，不用重開機了！

2- Create a Game Project

Note that you're creating a 2D game on Android, so the interface of the game must be drawn by you, so you do not need aactivity_main.xml file.

OK, your Project was created.

3- Preparing Images and sounds

You need a few images

• chibi1.png

• chibi2.png

• explosion.png

The Audio file of the explosion.

• explosion.wav
