Can somebody explain to me how you can get a redstone torch to turn on... like two switches need to be pulled before a door opens....
That would be an AND gate.
Here is what Minecraft Wiki says about it, with a picture that shows off the most simple AND gate.
To turn a redstone torch on, you need to place it. It should default to on unless you've setup some redstone circuit that turns it off.
A angate.
There is no such thing as an 'angate'. It is an AND gate. Meaning you need one lever AND another lever before anything will happen on the result end.
If you go on Minecraft Wiki, you will not find any pages for an 'angate'.
