It uses scene.my.variable scripts. Judging from all your scenes, you don't know how. I suggest first learn that before you can understand how I created the door. Try a tutorial scene here on Algobox, or a topic in "Thyme Scripting" in the Forums.
Umm... there's a subscribe button on your profile. I tried to see if it works. I subscribed to myself so if my subscribers reach 2 or higher, I know someone subbed to me.
actually, it's not impossible. after a few minutes of experimenting, I was able to get it through the finish and once even I went a little further, so I did 1 and a half of ground.
saw your youtube video
please give credit because those spinners, bowls, alternators, checkpoints are mine,
and the whole race was inspired by my marble race
bros03 - Thanks!
austin9700 - I know. Carykh is Cary Huang and does all the Algicoscathlon and Baugette and Marble Races and other stuff. JacknJellify is the Huang twins' main channel where they do BFDIA and BFDI. TisfatDude0703 has been uploading videos of the program, Tisfat, and recently has uploaded a first, and second marble race.
MarbleRacer - Saw it!
Oh, and MarbleRacer, do you want a Premium Pack? I renamed the Marble Race gadgets to Marble Race Standard Pack, and I want to upload another Marble Race Premium Pack. Answer please!
