Mapbase/Entities

One of the main goals of Mapbase is to expand upon the entities that can be placed in Hammer. This includes changes to existing entities as well as completely new entities. This article serves as an index regarding these changes.

Note:I/O/KV stands for Inputs/Outputs/KeyValues.

Base Changes

Many of Mapbase's changes (mainly new I/O/KV) apply to all of a certain type of entity, rather than any specific entity. The following articles go into detail regarding their respective base classes:

• Base Entity — Changes to all entities.
• NPCs — Changes to NPCs.
• Base Combat Character — Changes to NPCs and players.
• Weapons — Changes to weapons.
• Filters — Changes to filters.

Entity List

Important:This list is under construction and being adapted from Entity List on Mapbase's original wiki. The list was last updated for Mapbase v6.2.

The following list contains every entity that can be placed in Hammer when using Mapbase, including pre-existing entities as well as new entities. Each entity's status indicates how Mapbase has affected it compared to default Source 2013. Note that this generally does not count the base changes described above.
