== Supported Models ==
It's used by {{ent|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 {{ent|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.
Most newer games such as {{L4D2}} have a model folder called <code>props_doors</code>, which feature various door models (including static props that will not work for prop_door_rotating). For a door model to be compatible, it must be a physics prop and its model origin must be on the hinge side of the door, as doors rotate around its origin.

prop_door_rotating_checkpoint is a model entity available in Left 4 Dead seriesLeft 4 Dead series 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 ↓.
