While testing condition statements within command blocks, I discovered that repeated command block do not transfer their conditional statements DIRECTLY to a repeated command block that is looking for the conditional statement. The first picture failed to execute but the other three pictures worked without any problem. The second and third picture shows that they can get a conditional readout FROM chain and impulse command blocks and the fourth picture shows that repeated command blocks can output conditional readings TO impulse command blocks and chain command blocks (not shown). Also, in the picture, left to right points North.
