I was making a block and created it as a command block when it should have been a reporter
I couldn't work out how to convert it into a reporter (double-clicked and right-clicked everywhere I could thing of) and ended up recreating it again.
Is there a quick way of converting it?
You can only change a custom block's type (shape) when it is not currently in use in any script, otherwise we wouldn't even begin to know what to do to those affected scripts. So, make sure you remove any block instance from the scripting area or from any other block definition, then when you edit the custom block definition you get to also choose another shape for it, turn a command into a reporter and vice-versa.
Thanks - I didn't think to remove an instance of it from the script - tested it out and it works like you say
