This subdomain varies from player to player for OBJs and MTL files, so is there a API to tell me what the correct subdomain is? Or am I going mad? Please Help??
If you want to solve this problem without sending a request or looping through all CDNs, this trick works.
Here’s a little JavaScript code snippet that’ll do the job:
function get(hash) {
for (var i = 31, t = 0; t < 32; t++)
i ^= hash[t].charCodeAt(0);
return `https://t${(i % 8).toString()}.rbxcdn.com/${hash}`;
}
and the same thing in Python:
def get(hash):
i = 31
for char in hash[:32]:
i ^= ord(char) # i ^= int(char, 16) also works
return f"https://t{i%8}.rbxcdn.com/{hash}"
It creates a variable i with a value of 31, iterates through the first 32 characters of the string, and, on each iteration, sets i to itself Bitwise XORed against the integer representation of that character (or, alternatively, just the integer version of the hex value with int(char, 16) if you prefer it - as far as I can tell, it works in the same way)
Thanks to @Julli4n for helping me with the same problem three months ago.
