Circuit Map Help

Yeah, I was trying to make a circuit map, but as soon as I cross the start line it ends. What exactly is wrong with it?

There needs to be at least one checkpoint in the level. Without one, here's what the game's thinking:

Ok, he's in the finish line sector, has he hit all the checkpoints? Yup, give him a lap, and unhit all the checkpoints. What's that? No checkpoints to hit? No matter, just keep going.
One 35th of a second later.

And keeps doing that until;
Ok, he's in the finish line sector, has he hit all the checkpoints? Yup, give him a lap. What's this? He has all the laps he needs to win? Well end the level then!

Whenever I put the checkpoints, they all trigger when I trigger one.

You have to screw with the bitsets to tell it which order they go in. Don't ask me how, ask the Wiki.. it might know.

The heights? Huh. That's.... an odd way to do it.

Actually, enter directly into the flags box. Bitsets take too long.

Yeah, could you give me an example on that? Or a tutorial, perhaps? I'm not so good with circuit maps.

It's pretty simple. Just pull up the thing properties, and enter directly into the flags box. It says "flags value" right next to it. Your first would be 0, then 1, then 2, and so on.

And why a tutorial? It's one of the simplist things. Maybe an example.
