android - How to fade out audio/music between scenes? -

-

i'm trying music fade out when start android game. music plays in main menu , should fade out when player clicks play. can music stop, not fade out.

im trying fade out using this:

using unityengine; using system.collections;  public class musicscript : monobehaviour  {     static musicscript instance;     bool donefading;      void start()     {         if(instance == null)         {             instance = this;             dontdestroyonload(gameobject);         }          else if (instance != this)         {             destroy(gameobject);         }     }      void update()     {         if (application.loadedlevelname == "flappy drone gameplay screen")         {             fademusic();             if (donefading == true)             {                 destroy(gameobject);             }         }     }      ienumerator fademusic()     {         (int = 9; > 0; i--)         {             debug.log("here");             instance.audio.volume = * 0.1f;             yield return new waitforseconds(0.5f);             debug.log("lowered volume");         }         donefading = true;     }  }

any appreciated!

after bit of playing time.deltatime found simple way of doing fade :)

code in same problem (this code fades out music on particular scene keeps music playing other scenes):

using unityengine; using system.collections;  public class musicscript : monobehaviour  {     static musicscript instance;     bool donefading;      float timer = 5f;      void start()     {         if(instance == null)         {             instance = this;             dontdestroyonload(gameobject);         }          else if (instance != this)         {             destroy(gameobject);         }     }      void update()     {         if (application.loadedlevelname == "flappy drone gameplay screen")         {             fademusic();             if (donefading == true)             {                 destroy(gameobject);                 debug.log ("music destroyed.");             }         }     }      void fademusic()     {         if (timer > 0)         {             instance.audio.volume -= 0.015f;             timer -= time.deltatime;         }         if (instance.audio.volume == 0)         {             donefading = true;         }      }  }

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

php - Best Light server (Linux + Web server + Database) for Raspberry Pi -

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
