Place an info_landmark in both maps to mark the same location in both maps. |
To fire events in the next level, use the OnChangeLevel output to turn on an env_global in the current level. Create a logic_auto in the next level that checks for the state set by the env_global.
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.
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).
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.
Although the info_landmark should be in a corresponding position in both levels, the two trigger_changelevel brushes must NOT be in the same place in each level. If they are, you will be thrown into an infinite loop, endlessly ping-ponging back and forth between the two levels.
