info_changelevel is a brush entity available in Left 4 Dead series.

It is the entity that marks a level change. It safely changes the level in Left 4 Dead series, and defines the end-of-level safe room. Place an info_landmark with identical name in both maps that marks the same location in each map.

Risk of Confusion:This is trigger brush entity despite name of the this entity starting with info_ which is typical for point entities

Important:prop_door_rotating_checkpoint leading to the saferoom with this trigger that is also properly marked with CHECKPOINT nav attributes must be present when this entity spawns for transition to be possible.

KeyValues

Name (targetname) <string>[ Edit ]: The name that other entities refer to this entity by, via Inputs/Outputs or other keyvalues (e.g. parentname or target).
Also displayed in Hammer's 2D views and Entity Report. See also: Generic Keyvalues, Inputs and Outputs available to all entities

New Map Name (map) <string>: The filename of the next map (without ".bsp").; Warning:Setting this to current map’s name or leaving it empty will cause info_changelevel not to spawn.

Landmark Name (landmark) <targetname>: Changes of positions will take place on transition relative to this landmark.; Warning:Leaving this empty will cause info_changelevel not to spawn.; Tip:If for whatever reason rotating the map by 180 degrees is needed info_landmark can be named "coldstream3_coldstream4" and then entities that transition will be rotated 180 degrees around the landmark.

Start Disabled (StartDisabled) <boolean> !FGD: Stay dormant until activated (with theEnableinput).

Flags

~~Disable Touch~~ : [2]: Bug:Using this flag will cause info_changelevel to not spawn at all. Use Enable/Disable inputs instead. (tested in: l4d2)

~~To Previous Chapter~~ : [4]: Note:No usage in Left 4 Dead series

Inputs

EnableDisable:

Enable / Disable !FGD: Enable/disable this entity from performing its task

Outputs

OnChangeLevel: ~~Fired when the level changes.~~; Note:This output is in fgd but doesn't exist in-game.

-Safely changes the level in Left 4 Dead series, and defines the end-of-level safe room. It is unusual as it is a brush entity, where info_* entities are typically point entities. Place an [[info_landmark]] in both maps that marks the 'same' location in each map. In Hammer, <code>info_changelevel</code> will be listed in entity class selection menu when [[Entity_Creation|tied to a brush as an entity]].

-{{note|[[trigger_changelevel]] can also be used in Left 4 Dead, although it isn't recommended. It teleports survivors to next saferoom where info_landmark is but it doesn't take into account checkpoint nav squares. It's like teleporters, the info_landmark in the end safe room is the "center" of the brush, and the new map is the exit (the info_landmark again denoting the center so things are offset correctly). The transition from l4d_smalltown02_drainage to l4d_smalltown03_ranchhouse (Death Toll campaign) uses trigger_changelevel instead of info_changelevel.}}
