How can i exchange only a few blocks in minecraft bedrock with a command?

I have a 10 by 10 stone area and just want to replace 30 iron blocks at random and I don't know how. If I try to replace something then it would always replace the whole area. If so help me.

You could build 100 comand blocks and 100 random generators 😁

Do you use normal MC or World Edit to replace?

Normal mc

Make a comma and scratch a second block

So if I want to replace 50% stones with iron, I do it like this:

/ Replace stone Ironblock, Stone

Only works with world edit plugin.

It randomly replaces everything with his and iron blocks, do you have any plugins at all

I haven't tested it but try / fill coordinates stone, ironblock

If it doesn't work, get in touch again

Which minecraft version?

Does not work comes syntax error

So minecraft mine normal

It is not possible with / fill, can you describe in more detail what you need this for?

I just want to make a map for a friend where he can mine and find iron blocks by chance and then he can press a switch and where he has mined everything will be full again

Sorry not possible without plugins. I have found nothing.

Ok thanks anyway.

Is there world edit or these plugins for the bedrock version

Why don't you play the real Minecraft? I don't know a lot about minecraft bedrock.
