# Special Event IDs

These event IDs are hardcoded to perform specific actions when triggered.

Certain tileset slots also have special event IDs; see the [tileset information](https://bookstack.nsmbcentral.net/books/new-super-mario-bros/page/tileset-information#bkmrk-tile-behavior-change "Tileset Information § Tile Behavior Change Table") page for info on those.
