How do I check whether there's no entries inside a cellarray? I need to show the player an error log if the array is empty.

Is this correct?

PHP Code:

    new iArraySize = ArraySize( g_aCustomSpawnPoints );
    
    if( ! iArraySize )
    {
        log_amx( "[CSBR] No Custom Origins Found" );
        return 0;
    } 


If we use ArrayPushArray, does ArraySize go from -1 to 0 or from 0 to 1?

Why not just try ArraySize on a newly created array?
Also did you ever see an array with -1 elements, in any language? Does it make sense to you?

Well, why do we loop from 0 to ArraySize-1 if 0 is the starting entry which is blank then?

In the ordinary array loop

new const size = ArraySize(myArray);
for(new i = 0; i < size; i++) {

}

if size is 0 (empty) no iterations will occur. If size is 1, one iteration will occur. I'm not sure I understand your logic.

What I'm trying to say is:

PHP Code:

new iArraySize = ArraySize( myArray ), eData[ Data ];

for( new i = 0; i < iArraySize; i++ )
{
    ArrayGetArray( myArray, i, eData );
} 


Why would we even check the first item (0) if we know that it is blank? That's why I asked whether array size starts from -1.

Why do you assume first item is always blank? An ArraySize of 0 simply means the array has no item, it is empty. If you have an item it will be at slot 0 and the size fo array is 1.

Oh so, ArraySize == 0 means that the Array is empty and has no entries, and ArraySize == 1 means there's just one entry and the array isn't empty?

Yes, first element of array have index 0, and size of array is 1, so in loops you need to get arraysize-1 if using with ArrayGet* and <=

So, why is log_amx being sent when my array has 1 entry?

PHP Code:

public OnNewRound( )
{
    if( GetRandomZoneOrigin( g_fZoneOrigin ) == -1 )
    {
        log_amx( "[CSBR] No Zone Origins Found" );
        return PLUGIN_HANDLED;
    }
    return PLUGIN_CONTINUE;
}

GetRandomZoneOrigin( Float:fOutput[ 3 ] )
{
    new iArraySize = ArraySize( g_aZoneOrigins );

    if( ! iArraySize )
    return -1;
    
    new eData[ ZoneData ];
    
    new iEntry = random_num( 0, iArraySize - 1 );
    ArrayGetArray( g_aZoneOrigins, iEntry, eData );
    
    for( new i = 0; i < 3; i++ )
    {
        fOutput[ i ] = eData[ ZoneOrigins ][ i ];
    }
    return 1;
}

That's not nearly enough code for someone to tell, obviously your g_aZoneOrigins is empty.
