How to make Obsolete blocks like this:

  • 2: Set the color to R: 255 G: 0 B: 0
  • 3: Create the blocks shown on the image above and give them NO DEFINITION!!

𝒯𝒢𝒹𝒢! You made obsolete blocks!

thats not obsolete blocks
we have an anology in snap:undefined blocks.It happens when you somehow manage to remove the line of sight from the instance to the definition.it will become undefined after reload.

I agree. Obsolete means (by definition, I guess) they were once relevant, but not any more. A block can not be created obsolete. :smirk:

Because they aren't really obsolete blocks, they're just custom blocks.
The actual obsolete block is hard to get now without tampering with the XML because exporting scripts also include their dependencies now.

like @joecooldoo said, those are custom blocks. this is a real obsolete/undefined block:
