This gadget is used to create a checkpoint in your game. A checkpoint is a position in your scene where your player will respawn after death. Only one checkpoint can be active at any one time. A checkpoint is activated when the player first runs into the zone of the gadget. If there is another checkpoint further on and the player runs into it, then that becomes the active checkpoint. When they die, instead of returning to the start of the scene (which is the default) they will reappear at the last active checkpoint. You can also activate a checkpoint using wires so the player does not need to walk into a zone.


Example Tutorial (adapted from Media Molecule)

  1. Stamp a Checkpoint
  2. Stamp a light
  3. Point the light down at the checkpoint.
  4. Connect currently active on the checkpoint to the power port on the light
  5. Stamp a blank puppet
  6. Enter test mode.
  7. Possess the puppet.
  8. Walk up to the checkpoint and the light will go on.

  2. Activate Me
    Send a signal to this input connection to activate this checkpoint. Use this if you want more control over checkpoint activation that is provided by the player entering the checkpoint’s zone. Because you can have only one active checkpoint, this will automatically deactivate whichever other checkpoint is currently active.
  3. Currently Active
    This outputs a signal for the duration that this is the currently active checkpoint. You might use it to trigger related logic like a visual effect to show the player that this checkpoint is on.
  4. Just Spawned
    When a player dies and is respawned from this checkpoint, this outputs a pulse at the moment of respawning. You might use this to trigger a sound effect representing the restoration of the player, for example.
  5. Power
    This is where you turn the gadget on/off.

  4. Power
    This is where you turn the gadget on/off.

Lex Tips

Checkpoints are very useful for platforming games, as your player will get frustrated with you if they have to go back to the start every time they make a mistake. Place your checkpoints before or after particularly difficult sections of your map.
