I recently read this thread http://forum.sa-mp.com/showthread.php?t=356637.

And i thought it might be useful to have a database with all valid objectids in it. You can also add your own ids to the database easily if you have created your own objects.

I created it from the valid_model array from the pastebin link in that thread. So credits go to whoever made that. It was posted by guest. http://pastebin.com/xgMrfNNK

Here's the database

Valid object database (should go in scriptfiles folder): https://dl.dropbox.com/u/76608104/valid_objects.db

So you can do normal sqlite queries with the database.

Eg,

db_IsValidObject(objectid)
{

    new
        szBuffer[64],
        DBResult: dbrResult,
        DB: db_ValidObjects = db_open("valid_objects.db");
    
    format(szBuffer, sizeof(szBuffer), "SELECT null FROM objects WHERE objectid=%d", objectid);
    
    dbrResult = db_query(db_ValidObjects, szBuffer);
    
    if(db_num_rows(dbrResult))
    {
        db_free_result(dbrResult);
        db_close(db_ValidObjects);
        return 1;
    }
    db_free_result(dbrResult);
    db_close(db_ValidObjects);
    return 0;
}

EDIT: I posted the created database because it takes a while to generate. I think it took about 30 seconds on my PC.

This was how it was created.

new
    szBuffer[64],
    DB: db_ValidObjects = db_open("valid_objects.db");

db_query(db_ValidObjects, "CREATE TABLE IF NOT EXISTS objects (objectid INTEGER)");

for(new i=0; i < sizeof(valid_model); ++i)
{
    format(szBuffer, sizeof(szBuffer), "INSERT INTO objects VALUES (%d)", valid_model[i]);
    db_query(db_ValidObjects, szBuffer);
}

db_close(db_ValidObjects);

Wasn't sure whether to post here or snippets, i thought here would be better because its a DB not code.

Why not use the compressed array by Slice? He wrote a PHP code, which you can run after every SA-MP update to fetch all valid object models from GTASA directory.

Not sure how to use it TBH.

You can run it offline on WAMP Server. After you've installed it, open wamp folder, then open www folder and create a project folder. Paste php file in your project folder and run in the browser with localhost/project_folder/filename.php (URL). Though I'm not sure if Slice's code works as it gives me parse error on line 56 when I try to run it (I'm newbie in PHP).

That's got to be VASTLY slower than an O(1) bit check!

Definitely. I thought i might have been useful. (not so much now)

The thread i linked has been updated with a much better method to check if an object is valid. I don't understand how it works yet but i suppose i don't need to in order to use it.

To whom may it concern, note that these constructs are perfectly legal (though I do not know if it would be sane to use them, just general info, these are both deprecated and obsolete AFAIK):

if expression *then expression
if expression *then { expression }
// note that
// if ( expression ) *then expression
// is not valid
// --------------------------------
// you can also use *begin and *end instead of braces but then you must have *then preceeding them
if expression *then
*begin
    expression
*end
if expression *then *begin expression *end
// note that this kind of construct also can't make use of parentheses
// this is invalid: if ( expression ) *then *begin expression *end

In vehicle Mouse Wheel Detection

#define KEY_MOUSE_SCROLL_CLICK  (320) // VEHICLE ONLY 

public OnPlayerKeyStateChange(playerid, newkeys, oldkeys)
{
    if(newkeys == 320)
    {
        SendClientMessage(playerid, -1, "Mouse-click.");
    }
    return 1;
}

KEY_CTRL_BACK is used to detect mouse wheel scrolling backwards in vehicle

Need time machine to go few hours back!
my whole RP mode ( i was still working on it) with 6k+ lines disapired
DAMN!!!!
days of scripting ,designing ,mapping :/

SA:MP doesn't use defined keys, so this will detect whatever function you have assigned to the mouse wheel, not the mouse wheel itself. This also seems odd because 320 is not a power of two like the other keys, it is a combination of 256 and 64.
