This method was deprecated and has been removed in 1.13. See: https://bukkit.org/threads/moving-blocks-settypeidanddata-deprecated.299908/

Executing js rainbow() in 1.13 gives errors like this:

Drone build error: TypeError: block.setTypeIdAndData is not a function while processing function wrapperFn() { [native code] }

The Drone module needs some work to be compatible with 1.13. Many of the functions which use drone (e.g. cottage, castle, fort etc) no longer place blocks correctly. For example, beds, ladders, doors, windows etc all are placed incorrectly now. I'll try to get to this at some stage - if anyone wants to help please feel free to PR.

@jwulf you should try ScriptCraft 3.4.0 (or the development branch), since it includes my patch (#388) that works around the removal of block.setTypeIdAndData. This makes the Drone able to place blocks again, but as @walterhiggins mentions here, there are several little things that are still broken.

That did work @jonathanperret , but it's now broken on 1.15.2, as CraftEvil is not available.
