Legacy:XFallingVolume
The XFallingVolume sets where you die when you're falling off the edge of the map or building.
See Working With Volumes for how to use.
To create one, Add a Volume...
{To set it up you need to create a box. The height of the box generally isn't important just make it say ten high. You need to make it say slightly wider than the area that you're going to fall into so you don't get any gaps.
Now you need to right click on the volumes button it is at the bottom left hand side of the screen and looks like a blue cube. Select XFallingVolume. Now it may look as though nothing has happened. This is because it creates the volume box under the red builder brush. If you care THAT much you can move the red box slightly and you will see a pink box in exactly the same place the red one was. That box is the falling volume. }
Now if someone runs off the edge of the building they will fall and then die when they reach the box. (the box will be invisble of course)
This volume actually just damages the player (very heavily), and applies the death messege "Player left a small crater". For game styles such as Onslaught mode, boosting the damage rate in the volume properties will prevent a falling tank from surviving, or taking quite some time to die.
Due to the damaging type of this volume, when the player dies, they usually gib. To kill the player without gibs, see Killing Without Gibbing
