prop_door_rotating_checkpoint is a model entity available in 
Left 4 Dead series. It is a special variant of prop_door_rotating for checkpoint doors in the world.
It's used by info_changelevel to determine when to start the transition to the next map when all survivors stand inside. Usually only 1 door is used for ending checkpoint but it's possible to have multiple doors in which case all of them need to be closed. No doors is also possible but to achieve that the checkpoint must start with at least one door which is then killed afterwards via for example logic_auto's OnMapSpawn output. Having no doors this way might be useful in order to have saferoom activated by a button and utilizing Enable/Disable inputs of the info_changelevel entity or just have a saferoom that starts the transition immediately as all survivors touch it.
In Versus mode, the starting checkpoint door cannot be closed after it's been opened and it opens automatically if it remains closed for the amount of seconds specified in versus_force_start_time cvar ↓.
Note:Notices and information how to set up doors on prop_door_rotating page also applies hereNote:All Keyvalues / Inputs / Outputs are same as prop_door_rotating.Note:The sound that plays for the metal bar being removed is hardcoded. It can only be changed by editing the level_sound script for each map. More info on how to do so can be found hereGallery
Models used in official maps. 'Exit' and 'Dead End' signs should be usually facing inside of the saferoom. The models 0x and -0x differ by having hinge on the opposite side. For each of these models there's also static version with _static at the end which are usable as prop_static.
