AK-47's trigger_gravity example map
***********************************

	ABOUT
*************

	I created this example map to demonstrate the use and effects
of the trigger_gravity entity.

	MAP INFO
****************

	This map consists simply of two large rooms connected by a
short tunnel. One room is textured like Xen, and it has a roof using
the sky texture with a light_environment for it. The other room is
textured like a normal room on Earth and only has a light and an
info_player_start inside it. The short hallway has two trigger_gravity
entities inside it, each next to each other. One is on the Xen side,
and one is on the Earth side. The one on the Xen side makes the gravity
.2 of the original gravity setting, and the one on the earth side sets
the gravity to the normal setting. When you think about it, if the
entities are set up this way then the gravity is always appropriate
for each area since you always pass the correct trigger_gravity last
when going to a different area.

	ENTITY INFO/USAGE
*************************

	The trigger_gravity entity is extremely simple to set up and
use. You must tie the entity to a solid just like a trigger_once
entity, and when you pass through the (invisible) solid
the setting take effect. The gravity setting stay with the player until
he touches another trigger_gravity. Trigger_gravity has all of the
normal KEYS for a trigger_* entity, but a few are special:

Name: If you give the trigger_gravity a name, then it can be triggered
on and off. It starts on. If it is triggered off, that means that
nothing happens when you pass through it.

Gravity: This is the ammount of gravity you want there to be once the
player passes through the trigger. The number must be a decimal number
from 0-1. It can be 0 or 1, however. 0 means that there is no gravity.
1 is the number for normal gravity (Earth gravity).

There are also three flags worth noting:

Monsters: This means that the gravity also affects monsters.

No Clients: When checked, the gravity setting will not affect the
player.

Pushables: This means that the gravity also affects func_pushables.
