Command Conditional Statements

Commands are really useful in Minecraft. But, they are limited in the fact that they can't do conditions.
How this could be added is with a /statement command. How I was thinking it could work is like this:

  • /statement if(@s[tag="pizza"]) {summon cat} else if(@s[tag="burger"]) {summon wolf} else {summon parrot}
  • /statement while(@a[c=1,tag="some"]) {say This is annoying!}
  • /statement for(i=0; i<10; i++) {kill @e[type=item]}

There would also be support for !, <, >, <=, and >= for conditions.

I believe there are more conditional statements than these 3, but the only one I remember is the switch statement, and I don't really know how it works, so I couldn't make a great way of how it would work.

    Imagine they add this but only for Java. I can see them doing that.

    ChikoritaLover I'm pretty sure this exists in java, with /execute. /execute in java has more arguments.

    @EXDrill2522, there is a if condition in the execute command, but it doesn't seem to have else if and else callbacks.

    Also, the execute command doesn't have while and for loops.

    I just learned of another one called foreach. It is a shortener for for loops.

    for(Object o : list) {/**Do stuff**/}

    These are actually all possible in the Java Edition of Minecraft, there are loads of ways to create conditionals if you're willing to use scoreboards.

    For the first one, we can set up a scoreboard and run the following commands in order:

    execute store result score FakePlayer myObjective if entity @s[tag=pizza] run summon minecraft:cat
execute if score FakePlayer myObjective matches 0 store result score FakePlayer myObjective if entity @s[tag=burger] run summon minecraft:wolf
execute if score FakePlayer myObjective matches 0 run summon parrot

    For the second one, we set a redstone block next to a repeating command chain with the message, followed by a chain command block that removes the redstone block if the required entity is not detected:

    execute if entity @a[tag=some] run say This is annoying!
execute unless entity @a[tag=some] run setblock 12 23 34 minecraft:air

    And for the third one, we can increment a scoreboard value by 1 every time a command is run, and stop the entire command chain when the score is 10.

    In Bedrock Edition, I would advocate for getting the /stats command added to Bedrock Edition instead, to let the storage of command results to scores.

    This would open up much more possibilities and make it easier. I really don't want to mess with tons of command blocks.
