How do I detect players in a certain area using Command Blocks

How do I detect players in a certain area using Command Blocks - Crop hacker silhouette typing on computer keyboard while hacking system

I'm building this map and I have 4 different ways you can go and what I want is if someone walks through an archway or something the path will open up using Command Blocks to sense if a player has done that but I don't want to use Trip Wires. Can anyone help?

I have one trick to make this a little easier, so the command blocks are not under the door.

If you would like to detect players in a radius around a certain coordinate, instead of a radius around the the command block, you can use a command like this:

/testfor @a[x=X,y=Y,z=Z,r=RADIUS]

To make this a bit clearer, the X,Y, and Z in the command are the center coordinates of where the command block will test for players. The RADIUS in the command is how close the player needs to be to the coordinate (the X,Y,Z specified above), to trigger the command block.

Here is an example:

/testfor @a[x=15,y=45,z=39,r=3]

Hope this helped!

Answer 2

/testfor @a[r=4] works the best I believe. It works in 1.10.2 if you set the commandblock settings to repeat and to be always active.
