效果
PS : 這里本來打算做一個,隨著上下滑動屏幕,然后達到音量的增減,同時,同步的顯示當前的音量大小,但是這里面的currentVolumeLabel.text不會馬上的同步刷新,打印了當前線程是main. 可能有別的細節(jié)問題.暫時列為一個為解決的bug. 因為 : 先不在這里鉆牛角尖.耗時間有點不太好.
音效.

//說明: 這里的做法是創(chuàng)建每一個音效對應一個子彈,好比如一個腳本對應一個NPC一樣.
//嘗試過: 單獨之創(chuàng)建一個音效,每次點擊都調(diào)用這個,但是有點不完美的地方是,手速太快,當前音效還沒播放完畢,匆忙結(jié)束又從新開始播放一遍,很突兀.
//思考: 最佳方案應該是單純一個音效對象,每次點擊發(fā)射子彈的時候調(diào)用.

音效
簡單做了一個飛機發(fā)射子彈的操作,小總結(jié):
- 每一個子彈對應一個節(jié)點,每一個子彈音效對應一個AVAudioPlayer
- 注意發(fā)射子彈的邏輯.
- bgm音樂還有子彈音效可以自己隨便找一個就好,目前只是為了練手,不細致去求素材.
- 每篇代碼都不多

節(jié)點觸摸事件
- 這里主要是實現(xiàn)觸摸事件的思路.節(jié)點本身沒有提供點擊事件的操作,不像UIButton,只能通過對應的手勢點擊屏幕去找去判斷.
- 音頻資源可以自己隨便找.這個無所謂的
- 缺點 : 性能不好
視頻

PS : 視頻播放用真機去操作.模擬器播放fps掉非常低.達不到預覽效果
