/stopchain (or /stopfunction or similar) command to abort a function or commandblock chain

While functions are quite versatile, one major drawback is that when you run a function you can not abort it halfway through. This simple command could be used to break loops and to optimize larger datapack-based mods by cutting out extra command executions if they are deemed unnecessary.

When a "/stopchain" command is run, the command succeeds. If it is run by a command block, it will not activate the next block in the chain. If it is run by a function, it will immediately abort the function, skipping the rest of the commands after it. If it is a function being called within another function, it would only stop the function it is called in and return to the previous function. Alternatively, you might be able to use an optional argument to specify a number of layers to stop. This would just repeat the command multiple times.

A /stopchain command will fail if it is run with nothing to stop.This will happen if it is executed as an entity or run via the server console.

    You can do this already with scoreboards,

    Just create a runCode scoreboard in the dummy objective

    set it to 0 at the beginning of the command,

    use a conditional or an execute if to set it to 1

    all commands after the potential set-to-1will have "execute if score x runCode matches 0 run "

    before it, that way they will only run if you didn't "abort" the command chain by setting the score to 1

    the explanations are a bit too technical for me, but I think your idea has potential. Can you give me specific examples?

    sean111204, yes, but not in Bedrock. In Bedrock, there is almost no way to stop a command chain, except destroying it, and even then, if you replace it, it will keep going!
