Re: Convert STEAMID to Steam Community ID

This is a snippet I wrote for sourcepawn, but I won't use anymore.
Will convert Steam64 string to steam32 int

Don't even know if this will be of use for anyone.
This was built based on this

PHP Code:


		
			
// 64 bit max is 19 numbers + 1 (for teminator)
#define MAX_STEAM64_LENGTH 20

// 11 numbers is the total numbers that the 32 bit can hold, lets make sure its less than that by 1.
// 10 + terminator
#define MAX_INTEGERS 11

stock bool GetSteam32FromSteam64(const char szSteam64Original[MAX_STEAM64_LENGTH], int &iSteam32)

Don't mean to bump an oldish thread but this might save someone a tiny bit of time later....

Here is the Sourcemod adaption of YamiKaitou's code here with asherkin's tip:

So far its passed all my tests but let me know if you find any issues.

Re: Convert STEAMID to Steam Community ID

Hey guys, how can i convert U:1:0 to STEAM:1:0?
From steamID3 to steamID

From steamID3 to steamID

From "[U:1:1532443]":

1532443 / 2 = 766221,5

Since the number is odd, it is then "STEAM_1:1:766221".

If the number was didn't give an odd number, e.g. "766221", it would have been "STEAM_1:0:766221"

It sounded like you wanted the formula for converting it..

If you want the "status" command to show different output, you need to create a plugin that does it exactly as you want.

If you have any other plugins showing the one where you want the other, you need to adjust those plugins yourself, or hire someone to do it for you.

Re: Convert STEAMID to Steam Community ID

Note that the number 76561197960265728 looks like a constant, but it really isn't.

This doesn't really matter if you're converting SteamId2 to SteamId64 because SteamId2 only supports individual user accounts. However, SteamId3 also contains the account type and (optionally) instance ID.

The correct calculation for Community IDs:

Code:

((universe << 56) | (accountType << 52) | (instance << 32) | accountId)

The first 3 default to 1 for individual user accounts, which means the "magic number" for individual accounts is

Code:

((1L << 56) | (1L << 52) | (1L << 32))

which is 76561197960265728.

(L is there because 64-bit literals need it in the language I was using to double check this.)

If you try this to get group profile IDs or game server profile IDs, it fails spectacularly because they use different account types and instances.

Side note: The second section of a SteamId2 is the lowest bit of the account ID and the third section is the remaining 31 bits of the account ID. Hence, to get the account ID, it's

((third section << 1) | second section)

Very good to know, thank you a lot.

(No php extensions required :o)

PHP Code:


		
			
//Get SteamID and save it to $steam_id somehow



<?php

$steam_id=strtolower($steamid);

if (substr($steam_id,0,7)=='steam_0') {

$tmp=explode(':',$steam_id);

}

if ((count($tmp)==3) && is_numeric($tmp[1]) && is_numeric($tmp[2])){

 

 //The 'Magic Number': 76561197960265728

 //Split up so it can be calculated without an extension.

 



 

$steamidCalc=($tmp[2]*2)+$tmp[1]; //Work out step 1

$calckey='1197960265728'; //Second bit of the magic number

$pre='7656'; //First bit of the magic number

    

$steamcid=$steamidCalc+$calckey; //works out the ending of the steam community ID

    

$link="http://steamcommunity.com/profiles/";

echo $link; echo $pre; echo $steamcid;

 

 };



?>

By breaking off a few digit, it prevents php from outputting the number using scientific notation.
This does however, mean that this will have to be updated once there are enough steam accounts to make the numbers roll over.

Hope that's helpful to someone :wink:

Thanks!
