Forcefields are used to block the player from gaining access to a certain area. There are two types of forcefields: Invisible Forcefields, and Visible Forcefields. Invisible Forcefields are most commonly used to permanently block a player from getting somewhere (outer space, etc), or to cover a security view screen. They are harmless, and they generate a small visible ripple when shot. Visible Forcefields are usually placed in front of an area which can only be accessed after a trigger is activated (a Switch, Touchplate, etc). They also generate ripples when shot, and they cause damage to anyone who gets too close.
Invisible Forcefields
Create two rooms and separate them with a hallway. Mask the wall which you want to be the forcefield, and give it the BIGFORCE
texture (#230). Make it blocked and hittable with the B
and H
keys (B
and Ctrl + H
in 2D mode). There are two ways to make it invisible. You can make it
as transparent and dark as possible until it becomes barely visible, or
you can press M
on the wall to make it disappear entirely (but it will still appear in the game). In most cases the second method is preferred.
Visible Forcefields
Create two rooms and separate them with a hallway. Mask the wall which you want to be the forcefield, and give it the W_FORCEFIELD
texture (#663). It's not necessary to make this type of forcefield
blocked and hittable (it will be automatically). For variety, alter the
forcefield's palette (don't forget to apply the palette to both sides). If you want the forcefield to be toggled by a Switch, tag the forcefield [0,Channel]
, and place a Switch tagged [ActivationSound,Channel]
somewhere in the map.
