Entity description

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. In Hammer, info_changelevel will be listed in entity class selection menu when tied to a brush as an entity. It differs from trigger_changelevel in order to accommodate the core mechanics of Left 4 Dead:

• Also acts like trigger_transition. It transitions the prop_physics entities inside it to the destination level.
• Takes all players into consideration. info_changelevel refuses to make the level transition until all living survivors are within the volume and clear of infected.
• Level change, similar to trigger_changelevel ChangeLevel input (with Disable Touch checked), is instead fired when prop_door_rotating_checkpoint is fully closed.
• Provides location of an endpoint of a map in order for the AI to calculate an escape route. This, in turn, provides necessary information about map flow for the AI Director.
