Its easy, just place a trigger block where you want a checkpoint, then use mouse 2 and select button type weighted, cube or Sphere

- Weighted = Trigger once, good for make fun stuff, effects, block updates and more ( only one time )
- Cube = Trigger multiple, is similar to trigger once but if you go more times to that block you are always sending a signal
- Sphere = THIS IS FOR PLACE A CHEKPOINT... If you die you respawn on that place

Actually someone who explored all stuff from new editor knows that but if someone dont know there is this post.

Checkpoints are always good on large or hard maps so use it
