 | **Place tool** (P) | click = place on the collision floor under the cursor (snap to floor, grid snap), yaw = camera direction / facing the camera / 0° / type default; click + drag an object = move along the ground (its waypoints move along); drag the yellow knob = rotate (angle snap; a checkpoint's respawn node turns with it). Modes for the setups |
 | Setups | **Player start** moves the existing player (exactly one) or places a Llama with one start camera node 2 cells behind (moving keeps door nodes, carries the near nodes and the village fly-by trigger). **Checkpoint** = CheckPointPost + respawn node 0.4 ahead (floor height). **Exit** = LevelDoor in the cell centre + 1×1 FLOOR brush with collision material 16; target picked in the options bar (world/chapter names, "world finished 7,7,7"). **Secret** = Secret with a 3×3 box (2 nodes). Guards, alligators and spawners get one 4×4 box (and guards event bit 0) on every way of adding an object (`Edits.placeStrat`: Place tool, drag from Objects panel / Assets, double-click) |
