[Scenario]

So I have finally finished some code, but I want to have the system auto-login after registering. How could I do that?

When the player registers, save their IP.

new pIP[16];
GetPlayerIP(playerid, pIp, sizeof(pIP));

When the player connects, compare the IP in the user file with the IP the user logged in with. Once the user is logged in, save the IP to the user file again (incase they logged in manually with a different IP).

[Scenario]

I know what you mean. It's a tad bit more than what you mentioned, but I could probably do it. However, how do I auto-login players when they register?

[Conroy]

Whatever variable you alter when the player logs in, simply change the same variable when they register.

Example:

On log, PlayerLoggedIn[playerid] is changed to 1, meaning they can spawn.

When they register, PlayerLoggedIn[playerid] is changed to 1, meaning they are logged in and can spawn.

Hopefully this clears things up.

Okay, so I added "PlayerStatistics[playerid][pAuth] == 1", which was my variable for that, so it works now. Thank you!

No problem. Here to help.
