I have couple of sound clips i wanna play after collision how to do that? How to randomize that?
Check this: [url]How can I play sound files programmatically? [Solved]]
I can help you to get the random filename if you don’t know how 
What a name for a sound filename!
How the possible random sounds are called?
For example, if the names are like: material_wood_1.ogg, material_wood_2.ogg, material_wood_3.ogg, etc.
You can do (pseudo-something): “material_wood_” + random(1, 3).toString() + “.ogg”
But if the possible names are like: wood.ogg, metal.ogg, plastic.ogg, etc. (there is no relation between them).
*You could rename the files to use the easy way (above).
*Or you can use a structure variable, that maps a number with a filename:
Materials
0 "wood"
1 "metal"
2 "plastic"
Then you can get a random material name: scene.Variables().get(“Materials”).get(random(0,2).toString()).getAsString() + “.ogg”
Let me know how you are naming the files and I will be glad to help you
It should look like this:
Note that the JavaScript event is a sub-event, the code inside is:
[code]// random number between 1 and 5
var random_1_5 = Math.floor(Math.random()*5) + 1;
// get the sound manager
var sound_manager = runtimeScene.getGame().getSoundManager();
// play random sound, channel = 0, loop = false, volume = 100, pitch = 1
sound_manager.playSoundOnChannel("stenjanje " + random_1_5.toString() + “.ogg”, 0, false, 100, 1);[/code]
It’s pretty self-explanatory, I’ve assumed that the filenames are “.ogg”, if they are “.wav” you have to change the “.ogg” part in the last line of the code.
Remember to add the sound files in the resources manager, so they are exported to the project compilation directory, if the names are dynamic GD can’t do it for you 
Java is not supported in native 
Then you have to use C++, try this code:
For the C++ event, this is the includes list:
<iostream>
<stdlib.h>
"GDCpp/Runtime/String.h"
"GDCpp/Runtime/CommonTools.h"
"GDCpp/Runtime/RuntimeGame.h"
"GDCpp/Runtime/SoundManager.h"
And this is the code:
[code]// Random number between 1 and 5
int random_1_5 = rand()%5 + 1;
// Get the sound manager
SoundManager* sound_manager = &(scene.game->GetSoundManager());
// Play random sound, channel = 0, loop = false, volume = 100, pitch = 1
sound_manager->PlaySoundOnChannel(“stenjanje” + gd::String::From(random_1_5) + “.ogg”, 1, false, 100, 1);[/code]
Thanks man you saved me

when i’m trying to use another bunch of sound files on another scene with names “misaubija” 1-5 it reports this error:
