# Tips & Examples

* If you want a reliably-fixed spawn at a single coordinate, put the `coords` directly on the `SpawnData` entry and set `chance: 100`.
* Use `dynamic_spawn` to provide several named room positions; the spawn system can pick among them (good for themed item placements).
* Use `zones` for loose placement rules (e.g., “spawn somewhere in HeavyContainment”); `dynamic_spawn` overrides `zones` when present.
* To have the item replace existing pickups instead of adding new floor pickups, set `replace_existing_pickup: true`. Use `force_item: true` to only replace the same item type.
* To place items in lockers/racks, set `locker_settings.enable: true` and configure `locker_type` / `room` / `zone`.
* Combine multiple `spawn_settings` entries with different `chance` values to express multiple alternative spawn behaviors (e.g., 60% floor spawn in ZoneA, 10% locker spawn in ZoneB, etc.).
