# Things and Specials

This page documents the new thing types and special actions available in advanced map formats in dsda-doom. DSDA-Doom supports both Doom-in-Hexen and UDMF maps. See the [UDMF documentation](./udmf.md) for complete details about the `dsda` namespace.

## Thing Types

All Vanilla, Boom, and MBF thing types are supported in advanced map formats. This table defines the new entries.

| DoomEdNum | Name | Description |
| --- | --- | --- |
| 9001 | MapSpot | Marks a spot on a map (to be used by special actions). |
| 9013 | MapSpotGravity | Marks a spot on a map, with a marker subject to gravity (to be used by special actions). |
| 9043 | TeleportDest3 | Teleport destination subject to gravity which supports displacement with respect to the floor. |
| 9044 | TeleportDest2 | Teleport destination not subject to gravity which supports displacement with respect to the floor. |
| 9300 | PolyObject Anchor | Anchor defining PolyObject number via angle. |
| 9301 | PolyObject Start Spot (harmless) | Polyobject that aborts movement on touch. |
| 9302 | PolyObject Start Spot (crushing) | Polyobject that crushes. |
| 9303 | PolyObject Start Spot (harmful) | Polyobject that deals damage on touch. |
| 14001-14064 | AmbientSound | Places an ambient sound effect source. |
| 14065 | Custom AmbientSound | Places an ambient sound effect source via special argument. |
| 14100-14164 | MusicChanger | Changes music via DoomEdNum (0 to 64). |
| 14165 | Custom MusicChanger | Changes music via special argument (0 to 64). |

### Notes

- Poly objects have no sound.
- Poly objects may have visual errors in software mode.
- The custom ambient sound object only supports the ID argument.

## Sector Specials

Many sector specials are legacy effects from the original formats. More control can be obtained from sector properties in UDMF and the above line actions. DSDA-Doom has no concept of "terrain effects" (lava doesn't splash).
