I've acquired some important info for track builders from our checkpoint scripter Alphadin.
How checkpoints will work:
Step 1: Plant the checkpoint brick
Step 2: Name them the checkpoint #
Dimensions will be 2x32f
They reach up 1 plate + 10 1x1 bricks
You'll respawn at your last checkpoint when your vehicle enters liquid, when you Self Delete, or (possibly) when a vehicle event toCheckpoint is called. I still need to find out whether or not the checkpoints can be placed inside modterrain bricks or normal bricks.
