I want to speedrun any% glitchless random seed in 1.12 but seems to be no in-game timer for that version.

We use Time Attack method for Any% Glitchless Random Seed because of the Japanese community, so I would recommend using LiveSplit.

If you still want to use the In-game timer for 1.12, go to "Resources" and click on "Minecraft In Game Timer (1.7+)" by Geosquare

What is the Time Attack method?

I've already tried the 1.7+ timer but it just says 'Broken' when is open

Time Attack is similar to Real Time except you can pause the timer + game whenever. This is convenient for the Japanese runners because of how the broadcasting in Nico Live works.

I'm not sure why the in-game timer isn't working though, I'll ask Geosquare.

Hey Insane, I'm Geo the guy who made the timer. If you want to message me on discord with your problem I can help you out. Mine is Geosquare#2709

So if no warping, IGT=Time Atack? The timer in Resource doesn't work on Win xp. I wrote my own instead
