A clear, concise explaination of And/Or gates from http://www.dungeon-master.com/forum/vie ... 039388a0cf with an example of a puzzle needing coins from two sources - b

And/OR gates have 4 entries than can be ON or OFF.
When OFF, an entry has a value of 0.
The North entry has a value of 1 when ON.
The East entry has a value of 2 when ON.
The South entry has a value of 4 when ON.
The West entry has a value of 8 when ON.

This gives you 16 possible sums, from 0 (everything OFF) to 15 (everything ON).

Set the initial value to 0, so everything is OFF.
Set the target value to 7, so the AND/OR gate will be activated when north, east and south entries are set to ON.
The action, if Equal, should be "Set".
Target the trick wall.

Now, create a pushbutton, displayed as a Coin Slot, operated by coin that will remove the item, working once, targetting the AND/OR gate on NORTH, with a SET message.
Add another pushbutton on the same wall, displayed as a Coin Slot, operated by coin that will remove the item, working once, targetting the AND/OR gate on EAST, with a SET message.
This will do the double coin slot.

Finally, create a 3rd pushbutton on another wall, displayed as a Coin Slot, operated by coin that will remove the item, working once, targetting the AND/OR gate on SOUTH, with a SET message.

Years ago I put quite a long description at:
http://www.dianneandpaul.net/CSBwin/doc ... _Gate.html

May I add your 'alternate explanation' to the end of that?

Sure. You should add the context:
"How to remove a trick wall with an and/or gate, with the condition of putting 2 coins on a slot coin plus 1 coin on another slot ? "

Could You please add a line of text with the values of entries in and/or gate (down the "Edit And/Or Gate" screen) in the next release of CSbuild?
(something like that: "values: north=1, east=2, south=4, west=8" down the And/Or Gate screen)

Down of the "Edit Push Button" screen, there`s allready a line of text saying "Set Opens Doors, Opens Pits, Enables Teleporters, and Opens False Walls". That simple line helped me A LOT working on CSbuild. I`m sure line with these values would help NEW CSbuild users a lot, who don`t know that yet, without asking you on the forum.
