I created 3 command blocks that are always on repeat, but the problem is I don't have access to the command blocks doing the commands once the command has started. Is there a way for the command to be done for 15sec (for example) and then stop the command from being executed regardless of any other conditions?
I tried to use lever with redstone but the result was not exactly what I was looking for. The start is perfect but the ending can give me extremely different results based on how long the command was active for since I don't have access to the command block or lever.
Currently this is what I have: When the lever is activated, do the command until the lever is deactivated.
