trigger_changelevel
is a brush entity available in all Source games. Upon being triggered, it will prompt the game to load another level.
Start Disabled
option is set to Yes
the brush will become solid to the player, getting it stuck if the transition happens within its volume.Contents
Notes
Place an info_landmark in both maps to mark the same location in both maps. The info_landmark must be in the player's PVS when the level change is triggered. If it is not, the level change will fail. Both info_landmark entities must have the same name. This name must not have any spaces in it. They also must not be inside a solid brush. Both the landmark name and the map name must be less than 32 characters in length.
Level transitions must be two-way. That is to say, there must be a trigger_changelevel in the next level that points to the current level, as well as the trigger_changelevel taking the player to the next level. If a one-way level transition is desired, simply make this second trigger_changelevel inaccessible to the player (and/or check the Disable Touch
flag).
To fire events in the next level, use a trigger output to turn on an env_global in the current level. The entity has a few pre-defined states but you can manually type your own custom state. Create a logic_auto in the next level that checks for the state set by the env_global. Now use the OnChangeLevel output of the logic_auto to trigger events.
To control which entities go through the level transition, create one or more trigger_transitions and give them the same name as the landmark. Any entities within the trigger_transition(s) will go to the next map.
