Yeah, I've always wanted a feature like this! I do have a way around it though, and I used this in my new project called Mini Projects.

Make a hitbox around the size of the mouse pointer, then put this code in the hitbox:

when green flag clicked
hide
forever
go to [mouse pointer]
end

when green flag clicked
forever
wait until <touching color [...] ?>
Your function
end

Hope this helps!

While the workaround for it is easy, I totally support. This would make for a lot of interesting mazes.

You can find a way around that.

First, make a sprite that is just a 1x1 black dot. Set the ghost effect to 99%, and tell it to always go to the mouse pointer. Then, just use that sprite for color detection.

wow! thats smart! i never thought of that
thx!

This is useful for reducing the amount of work needed to do such a simple function. A workaround isn't always a solution, so a block would be ideal for this. It's not ideal the fact you need to make an entire new sprite to track the color your mouse pointer is touching. Minimizing work and making programming easier is a design goal of Scratch.

Why 99% can't you do 100%?

I just found out that it’s way easier in Snap!

set [? v] to []
end

I think the workaround to this is fairly simple, it can kind of only be used in one sprite though.

No support. They could detect when you heart and starred, and make a project only playable if you get a certain amount of hearts and stars.

How does letting you detect what colour the mouse pointer is touching allow for this???
