Hello,

I just got back into Minecraft after a long long time and I started working on an adventure map.

Right now I'm trying to do some new cool redstone contraptions but I've got some issues with the new command block system.

What I want to do is to simply make redstone activate when a player moves close to the command block.
I have a secret door that should open but I really don't want to use regular pressure plates.

I know that command block pressure plates used to be possible but I really need some help here.

If any of you redstone geniuses can help me out it would be greatly appreciated!

If I'm understanding correctly you're talking about how you used to be able to use /testfor @p[r=5] in a repeating command block and a comparator would output a signal if someone came within that radius. If that's the case you can still do the exact same thing only the command and syntax has changed to /execute if entity @p[distance=..5] This command will execute from the position of a command block, to execute from a different location (like your door) you'd specify that in the targeting selector like so: /execute if entity @p[x=100,y=64,z=100,distance=..5] This will turn the comparator on if a player comes within 5 blocks of 100 64 100 and will deactivate when they are not in that area.

Hope that helps. There are a lot of things /execute can do and I don't think I can be much more helpful without more details of what, exactly you want to have happen. Remember that for these to work the way you want they should be in a Repeating Commandblock that is Always Active and should be in an area that's loaded when the player is at the target area (meaning nearby on in the spawn chunks).

I think this might be just what I am looking for.

To be more specific with what it is I want to do, I want a player to walk into a corridor and when the player comes within 2 block from the command block, it sends a signal that triggers the redstone that I have connected to a trapdoor.

I have yet to try what you told me but if that is what it'll do then it's just what I needed!

Yeah, that command should do it for you even without the coordinate targeting criteria. The only problem I could foresee is that this activates when the player gets in range and deactivates when they're outside so it'll only work IF your door is within the 2 block radius activation area near the command block. There are ways to modify it to make it more versatile- using the coordinates to target the position of the trapdoor might make it a little better in terms of function.

I just wasn't sure if it was one of those things where the command block would be powering a circuit 20+ blocks on direction and that activating a door 20+ blocks a different direction depending on if a player is in a completely different 4th location. This would also be totally possible and no big deal using combinations of /execute and /setblock but it doesn't seem like you need anything that complex.
