Displacement level change? Created 9 years ago2015-09-01 00:50:32 UTC by Mmoonyy

I wanted to know exactly how to do a displacement level change, the tutorial on how to change levels here mentions displacement change but doesn't show you how to do it. Now a displacement change is like teleporting, your in a corridor, and next thing you know your in Xen or your room or something. Thanks.

Exactly the same as a corridor level change, just make the second map something completely different! Use env effects (fades and... Well, pretty much just fades) to hide the transition.

info_landmarks simply tell the engine which part of each map in a changelevel corresponds to the opposing map. They don't need to be anywhere near the changelevel and serve only to provide a point of reference in each map. The landmark must be in both maps.

The player will not 'spawn' anywhere in a standard changelevel. They will simply transition between maps in exactly the same place they leave the previous map - this is what the landmark entity exists to accomplish.

Wherever the player is relative to the info_landmark is where they will appear relative to the info_landmark in the next map, basically. This is the case no matter how you trigger the changelevel entity (it can be triggered like any other entity, or used as a walk-into trigger itself).

Here are two examples:The yellow box is the landmark, the green box is the player and the orange rectangle is a trigger_changelevel.
Note that regardless of how the changelevel occurs, the player will always be in exactly the same position relative to the landmark.

In the second example, the trigger_changelevel has been triggered by something else - perhaps a button on the wall. The location of the trigger_changelevel has no bearing whatsoever on the location of the player in the next map.

Thank you very much!
