I would like to make a command block that when he found someone(testfor) in a specific condition (like, survival mode) a redstone signal will appear and activate another command block(the command doesn't matter)

If you can please to post a picture of how this setup (in redstone) should look like I will be pleased.


Place a command block with the /testfor @p[whatever] command.
Then, a Redstone Comparitor facing outwards from the command block.
From there, place your redstone or any Redstone Contraption that needs the input.

Note: If the comparitor's signal isn't strong enough (1 block worth of power), place a Redstone Repeater after the comparitor and any output should now have 16 strength.

A comparitor only outputs a signal power of 1. Add a repeater to make that 16.
