Can someone make Stretch Blocks as a NPC?

Here's some reference from the Super Mario Wiki:
https://www.mariowiki.com/Stretch_Block

You can make that in vanilla with no cool and epic luafications through events and layers. Lua can also help with it making it more precise, but it's not really needed.

I double this request. Stretch blocks really should have been base game and having to make a thousand events for a few stretch blocks is tedious and the SMBX community would be better served if stretch blocks were a basegame npc. So please try not be so quick to dismiss this request, Fuyu. Just because it technically can be done in a hacky workaround doesn't mean that it's convenient nor does it mean it could've been done in a better and less hacky manner.

I third this. I've heard that it might be a difficult NPC to make but if it gets added then a ton of new setups would be available.

Ah yes, a thousand. Move in, stay, move out, stay.
Can you elaborate on what part of this is hacky which you would want a NPC implementation to fix? I'm curious. Currently I'm not sure whether making it as NPCs wouldn't introduce jank rather than remove it from the method that worked for the past decade.

You do, indeed, need a bunch of events since all 4 move blocks need to move at different speeds and you can only move one layer at a time. Once you do set it up, though, it's a copy-paste job. Still, it'd be a neat custom NPC, albeit probably not as a basegame one.

Ah, I forgot about the event speed restriction. My mind's too infected by just being able to set layer speeds in a coroutine... Sorry about that!

Regarding doing this vanilla, I remember trying to do just that pre-X2 and ran into a problem whenever the blocks were moving horizontally. The player would get stuck in them and zip along their surface thanks to good ol' vanilla SMBX layer and collision detection.

Not sure if that specific sort of collision jank has been addressed since then or not, but that might be one reason why such an obvious addition hasn't been done before now.

It hasn't been addressed basegame yet, but antizip.lua does fix it.

Someone made easy firebars, so making easy stretch blocks would be the next step.

I didn't make it as an NPC...far from it. But I did create a level in which you can just copy and paste both the vertical and horizontal moving versions wherever you'd like in it. Hope it will help.

To keep this from happening I made the horizontal version into 2 block-types, a 32x32 and 31x32. The 32x32 is the center, so when standing on the expanded 31x32s you'll retract until back on the central 32x32 block, after which you won't move. It's a jank workaround, but it keeps you from being thrown around on retraction.
