As you
have probably seen in the game it's possible to have items like weapons and health that are
floating in mid air.
This is an easy thing to create and these short
steps will show you how.
Somewhere in your
level place your item, we'll use a weapon_shotgun.
Place it high of the ground about 128 units above
the floor.
With the item still
selected press N to get the entity info up and
tick the box that says 'suspended'.
Compile your map
and go check that shotgun floating in the air.
This is a useful
trick for space maps or maps which contain jump
pads.
