== Keyvalues ==
{{KV|[[targetname|Name]]|intn=targetname|string|The name that other entities use to refer to this entity.}}
{{KV|[[Classname|Class]]|intn=classname|string|Determines the characteristics of the entity ''before'' it spawns. {{Tip|Changing this on runtime still has uses, but should be used sparingly, as certain entities expect entities to have certain classnames. For example, using a classname defined in [[S_PreserveEnts]] will persist the entity on new rounds.}}}}
{{KV|[[Globalname|Global Entity Name]]|string|intn=globalname|When entity transitions to different map which has an entity with same globalname (and classname) properties of this entity (color, origin, angles etc.) will be copied over to that entity. (unless the given property is marked not to transfer e.g. model) 
:{{Important|Meant to be used in singleplayer games which have {{hl2}} style map transition ({{l4ds}} is '''not''' one of those)}}}}
{{KV|Model|intn=model|string|In-game representation of the entity to display. For [[brush entities]], this is a reference to a non-zero [[bmodel]] index in the current BSP. For [[point entities]], this is the path to an [[MDL]] [[model]] or [[VMT]] [[sprite]], relative to the game's root directory. Not all entities will actually render the model, and only specific entities will [[precache]] the model defined here (non-precached models cannot be displayed).}}
{{KV|[[Origin]] (X Y Z)|intn=origin|coordinates|The position of this entity's center in the world. Rotating entities typically rotate around their origin.}}
:{{bug|hidetested=1|Editing this manually in Hammer does not move point entities accordingly in the editor.}}
:{{note|Brush entities with this keyvalue count towards [[leak]] tests, whereas they do not if this keyvalue is absent.}}
{{KV|[[Pitch Yaw Roll]] (Y Z X)|intn=angles|angle|This entity's orientation in the world. Pitch is rotation around the Y axis, yaw is the rotation around the Z axis, roll is the rotation around the X axis.{{Note|This works on brush entities, although Hammer doesn't show the new angles.}}}}
{{KV|[[Spawnflags|Flags]]|intn=spawnflags|flags|Toggles exclusive features of an entity, its specific number is determined by the combination of flags added. In hammer it has its own tab in entity properties called '[[Hammer_Object_Properties_Dialog#Flags_Tab|Flags]]'}}
{{KV|Damage Filter|intn=damagefilter|target_destination|Name of a filter that controls which entities can damage this entity.}}

=== Parenting ===
{{KV|[[Parent]]|intn=parentname|targetname|Maintain the same initial offset to this entity. An attachment point can also be used if separated by a comma at the end. (<code>parentname [targetname],[attachment]</code>) {{Tip|Entities transition to the next map with their parents {{l4ds|not}}}}{{Tip|{{Ent|phys_constraint}} can be used as a workaround if parenting fails.}}}}

=== Vscript ===
{{KV|Entity Scripts|intn=vscripts|scriptlist|Space delimited list of [[VScript]] files (without file extension) that are executed after all entities have spawned. The scripts are all executed in the same script scope, later ones overwriting any identical variables and functions. Scripts executed on the [[worldspawn]] entity will be placed in root scope.|since=L4D2|also={{tf2branch}}}}
{{KV|[[Entity_Scripts#Thinker_Functions|Think function]]|intn=thinkfunction|string|Name of the function within this entity's script that'll be called automatically every 100 milliseconds, or a user-defined interval if the function returns a number. Must be present when entity is spawning, setting it later (for example via AddOutput) has no effect. Avoid [[expensive]] operations in this function, as it may cause performance problems.|since=L4D2|also={{tf2branch}}}}

=== Rendering ===
{{KV RenderFields}}
{{KV Shadow}}

=== Miscellaneous ===
{{Expand|
{{KV|[[Effect flags|Effects]]|intn=effects|flags|Combination of effect flags to use.|nofgd=1}}
{{KV|[[Lag Compensation]]|intn=LagCompensate|boolean|Set to '''Yes''' to lag compensate this entity. Should be used very sparingly!|nofgd=1|since=L4D2}}
{{KV|Is Automatic-Aim Target|intn=is_autoaim_target|bool|If set to 1, this entity will slow down aiming movement for consoles and joystick controllers when the entity is under the crosshairs.|nofgd=1|since=CSGO}}
