This file contains ambiguous Unicode characters

This file contains Unicode characters that might be confused with other characters. If you think that this is intentional, you can safely ignore this warning. Use the Escape button to reveal them.

This table lists every single entity in Mapbase that can be chosen in the editor, including those that already existed in HL2 and its FGDs. Each entity's status indicates how Mapbase has affected it. Summaries are given for each entity to briefly describe how they were affected and entities with large changes may have their own pages, in which case their names would be clickable.

Keep in mind Mapbase makes several changes to the base entity code, so technically every single entity in Source has been changed or affected by Mapbase. Those changes will not be counted unless the base class covers a thin range of entities.

This list was last updated for Mapbase v6.2.

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

Legend:

Status	Emoji/Symbol	Meaning
Stock	➖	This entity has not been changed.
Changed	🔀	This entity has been changed by Mapbase.
Obsolete	🅾️	This entity has been partially or fully obsoleted by Mapbase.

There is most likely some information missing or miscellaneous stuff left out, but this should be the most comprehensive list available.

Entity Name	Status	Summary

ai_goal_actbusy_queue	⏺️	This derives from ai_goal_actbusy and receives the same improvements.
ai_goal_assault	➖
ai_goal_fear	✳️	Allows mappers to control the fear behavior allies formerly only used automatically against hunters.
ai_goal_follow	🔀	Wait points have been improved and unmarked formations have been added to the editor, but follow behavior itself hasn't changed much.
ai_goal_injured_follow	⏺️	This derives from ai_goal_follow and receives the same improvements.
ai_goal_lead	🔀	It has angles in Hammer now, but other than that it just has indirect changes from ai_goal_lead_weapon.
ai_goal_lead_weapon	🔀	Timeout time can be specified, weapon_bugbait is no longer hardcoded, etc.

This allows ai_relationship to be used on top of a global relationship modification. For example, let's say you want all npc_metropolice (CLASS_METROPOLICE) to be hostile to npc_combine_s (CLASS_COMBINE) except for a few npc_metropolice that don't attack soldiers for environmental or balance reasons. This entity allows you to have that kind of relationship setup.

logic_relay	🔀	New TriggerWithParameter/OnTriggerParameter I/O for using parameters on the relay.
logic_relay_queue	✳️	Queues excess triggers instead of discarding them. This means when a logic_relay_queue is still firing its delayed outputs and it receives another trigger event, it queues it up so when its output events are over, it fires that queued trigger with its data intact.
logic_scene_list_manager	➖
logic_script	◀️	An entity that acts as a container for VScripts. Ported from the Alien Swarm SDK.
logic_script_client	✳️	A version of logic_script which runs scripts on clients.

math_counter_advanced	✳️	A special version of math_counter with advanced inputs, outputs, and keyvalues for advanced operations and specialized calculations.
math_generate	✳️	Generates numbers from a variety of algorithms, mostly taken from material proxies. (e.g. generating a sine wave)l
math_lightpattern	✳️	Replicates baked light patterns and fires outputs accordingly. See the dedicated article for more information.
math_mod	✳️	Modifies and outputs input values with the specified value and operator. For example, it could be configured to add 2 to each value sent to this entity, outputting the result each time. This is to create I/O "pipelines" that demand instant operations limited by, say, using a math_counter with delays.
math_remap	➖
math_vector	✳️	Allows for operations on vectors like "0 0 0" or "2509.677 384.001 204.5". Based on math_counter.
