the

if on edge, bounce

block is an oddly specific block. Probably the weirdest block in the game
it would better to have

on edge? :: motion boolean

and

bounce :: motion

Not only can you completely recreate the “if on edge, bounce” block

if <on edge? :: motion> then
bounce :: motion
end

but it will be a lot easier to make other things, like pong, and stuff

if <touching [paddle v] ?> then
bounce :: motion
end

I'm cursed :3 :) :P :: motion :: hat block

on edge already exists and I'm pretty sure the bounce block is a dupe

The “bounce” stack block shouldn't exist because it's oddly context sensitive. How does it know what to bounce off of? What happens if you put the “bounce” block outside of a C-block, or in one with no sprite collision-related booleans? What if it decides to bounce off of the wrong object?

As pointed out, an “on edge?” Boolean block already exists in Scratch 3.0 — specifically,

<touching [edge v] ?>

Although it is not on the Official List of Rejected Suggestions, a generic “bounce” block is a suggestion the Scratch Team has seen before, thought about, and decided not to implement to Scratch, as it is not possible to “bounce off nothing”:

That's true, which is why we've declined to add this. […]

However, a similar block suggestion, an "if touching [sprite v], bounce" block, is not rejected and has been suggested before in this topic. In which case, feel free to continue the discussion there if you are in support of it.

Thanks for doing the research
Closing this.
