This project is unfinished & has been abandoned. There are better autofarmers out there nowadays, go use one of those instead. It is also apparently now detectable by the anticheat.
Growtopia uses a mutant handle called \Sessions\1\BaseNamedObjects\Growtopia which prevents us from opening more than one instance of the game at a time. To circumvent that, we first suspend all the instances of the game (since it'll crash if we just attempt to delete the handles), and only then delete the handles and open a new game.
When a new instance of Growtopia.exe is launched, we first suspend all other instances of the game using SuspendThread.
Then we get all the handles in the system with NtQuerySystemInformation and filter out those that are not owned by the latest Growtopia process). We get the names of the remaining handles by duplicating them with DuplicateHandle so that we can retrieve information out of them with NtQueryObject.
Then we filter out handles with incorrect names and end up with the handles that we have to delete.
To do that, we use DuplicateHandle with DUPLICATE_CLOSE_SOURCE and specify no process to duplicate to.
Once all the handles are deleted, we launch a new Growtopia process, which will create new handles. Now we resume all the other
Growtopia.exe's with ResumeThread and we've ended up with one new Growtopia instance open.
