There are probably going to be more blocks added to the Scratch code block library, and among those, an important set would be sprite stretching. This would be helpful for several use cases:
-A rectangular prism viewed from the side, spinning orthographically.
-General isometric 3D simulations or demos.
-Mode-7-type graphical effects, maybe to be used for a character bouncing or smear frames.
I know many people have requested this and I hope that Scratch Team does implement this for more complex games and for flexible programming.

i mean they kinda already have it with the fisheye effect kinda if you haven't seen link
but yeah it would be nice if they added it officially imo

I'm not using that, it's way too complicated to use in specific use cases.

Please don’t make a list of suggestions. Instead, make a topic for each of them.

I mean to say this respectfully, it's a showcase of different use cases, not separate suggestions.

It could look like this:

stretch x to (50) %::motion // changes width to 50% of the current width

If the block runs again it stretches the sprite again, so two of these 50% blocks stretch the sprite to 25% of its width for example.
If the costume is a square:

stretch x to (50) %::motion // a rectangle, but rotated
turn right (45) degrees

turn right (45) degrees // a rhombus
stretch x to (50) %::motion

This block is useful for sprites stretched along multiple different (not perpendicular) directions:

reset stretching :: motion

Whoops, misunderstood you. This is however a dupe.
