Editing Making an invisible floor

'''Invisible floors''' is an effect that allows a level designer to put invisible solid sectors on a pit in which the player can walk, simulating flying or walking on mid-air. 

==Implementation==

There are several methods to obtain this effect. This is just one way of accomplishing this.<br>
'''Steps''':<br>
1. Create a sector inside another sector and make sure they don't share any lines. <br>
2. Check the sector's properties, and make a note of what the sector's number is.<br>
3. Edit all the lines on the inner sector you just made and set all the sector references to the sector's number. Both sides of all its lines should reference it.<br>
Done.

==Limitations==

*An invisible floor needs a sector surrounding it, so making one directly against a wall is impossible.
