I basically meant that switches are the same whether in RMXP, RM2K3, or RM95.

Basically, a switch is what it says on the tin. If you want a light to turn on, then you turn the light switch on. Same with things in RM2K3. Say you've got an event that you don't want to happen until someone's flicked a switch (just to make it physical).

You'd have the switch event in the middle of the room, as an Action Key event.

When the Hero activates it:

Turns Switch [0001] ON

The switches are all numbered ( 0001, 0002, 0003, 0845 etc), and are either ON or OFF. Usually they're not ON until you turn them on.

Methinks I'm going mad with this.

BASICS: a switch is something you use if you want to make something happen after something else has happened.

Then, if you've got an event that relies on a switch to work, that event would have a Precondition, or you'd use a conditional branch in the event.

Follow me so far?
