This suggestion is about suggesting the abillity to stretch sprites. Currently, you can't stretch sprites.

Support because I know there are a lot of good use cases for this

MagentaDude1359

you can just use fisheye stretch

P-P-C

100 % support
It would be super useful for animation

use this

Support it has a lot of uses such as health bars, animations, projects that use rotation, already been implemented with scratch alternatives and wouldn’t make scratch worse also the width and height parameters would be useful for tile based projects, text engines and number counters

You can split the sprite into 8x8 pixels and move those pixels around as well as a Super-Mario-Kart-like different-sprites-for-different-widths for bitmap sprites, or add dots to the edges of vector sprites, but both of those are difficult to do correctly (and in the case of the latter inaccurate), so this is a great suggestion.

I support this idea, but if the width and the height are not equal, what would be the size then?

Support. ST, where are you?

How do you go past 600 pixels in height

https://scratch.mit.edu/projects/1149612585 Seven-Sez-Two is too tall, is there things to help me

Also paddle literally said this is a good idea how is this not added

Which isn't perfect and is fairly complicated.

Ok but then the shader would be kinda complicated as first you would have to scale horizontally to one which means knowing the width. But I don't know if GLSL has AABB detection

That's what vertex shaders are for.

Yes, doing this with a fragment shader would be next to impossible unless you already knew the width and height of the sprite, and there was only one sprite on the stage. Vertex shaders exist solely to move vertices (in this case, the mathematical points describing the triangles that that make up a sprite) so stretching isn't hard for them.

Yeah but to stretch you must know the width of the costume so you can scale the x coordinate by goal width / width.
Also I think this is how stretching would work

#ifdef ENABLE_stretch
	{
		vec2 stretchFactor = vec2(u_stretch, 1.0); // Example: stretch 2x in X, no change in Y
    
   		vec2 vec = (texcoord0 - kCenter) / kCenter;  // Normalize texture coordinates around center
    	vec2 stretchedVec = vec * stretchFactor;    // Apply the stretch factor

    	texcoord0 = kCenter + stretchedVec * kCenter;
	}
#endif
