sound_exists(index);
| Argument | Description |
|---|---|
| index | The index of the sound to check the existence of. |
Returns: Boolean
This function returns whether a sound exists (true) or
not (false). Note that if the index you search for has not
been initialised previously, this function will cause an error as
it is searching for non-existent asset indices.
if sound_exists(global.Music)
{
sound_loop(global.Music);
}
else
{
global.Music = sound_add(working_directory +
"\MainMusic.mp3", 1, 0);
sound_loop(global.Music);
}
The above code checks to see if a sound exists. If it does it is set to play in a loop, but if it does not, it is loaded into memory from an external source and then set to loop.
