将带有音频的处理草图导出到JavaScript [英] Exporting a Processing sketch with audio to JavaScript
问题描述
当我将草图导出到JavaScript时，如何在我的处理"草图中实现声音?
How could I implement sound in my Processing sketch that works when I export the sketch to JavaScript?
我在处理"中写了一个草图，其中包括两个音频(.wav)循环.这些循环通过mousePressed()和mouseDragged()上的Movie类播放.草图可在正常/Java模式下工作，但在更改为JavaScript模式后不会加载.当我删除声音时，草图仅在JavaScript模式下可用.
I've written a sketch in Processing that includes two audio (.wav) loops. These loops are played through the Movie class upon mousePressed() and mouseDragged(). The sketch works in normal/Java mode, but does not load when changed to JavaScript mode. The sketch only works in JavaScript mode when I remove the sound.
我注意到，使用Movie类的其他草图以及诸如Minim之类的库的草图示例在我将其导出到JavaScript时均无法加载，因此我认为这是我的实现而非实际问题代码.
I've noticed that other sketches that use the Movie class as well as sketch examples of libraries such as Minim fail to load when I export them to JavaScript, so I think it's a problem with my implementation rather than the actual code.
我计划最终通过iPad上的Safari使用草图.
I plan to ultimately use the sketch through Safari on an iPad.
谢谢.
推荐答案
For minim, you can use a relatively simple shim such as https://github.com/Pomax/Pjs-2D-Game-Engine/blob/master/minim.js - include it as a normal JS script on your page before loading any sketches, and your sketch won't complain that minim is an unknown thing.
由于Processing.js将您的草图编译为本机JavaScript，因此Minim之类的全局对象也可以简单地在JavasScript中进行仿真:只要您要调用Minim的函数在您的JS垫片"中定义，事情就可以正常工作很好.
Because Processing.js compiles your sketch to native JavaScript, global objects like Minim can simply be emulated in JavasScript as well: as long as the functions you're calling for Minim are defined in your JS "shim", things should work just fine.
更一般地说，由于处理库是预编译的Java VM字节码，Processing.js无法加载它们，因此任何导入语句都将被忽略.
On a more general note, because Processing libraries are precompiled Java VM byte code, Processing.js cannot load them, so any import statement is ignored.
