technically you could do this with values I think

You could very easily do this with variables rn

This is probably possible already - in some way - but I feel like a dedicated block would be easier and nicer! :slight_smile:

Nice idea, but there is one problem.

Unlike in Scratch, Hopscotch has the coding editor on screen at a different time than the stage, so it might be hard to grab colors from characters.

So it might be hard to detect an object’s color because you don’t know the color?
I don’t see how that might be a problem. If you coded it to set color, you’ll know what that color it set to is. And if you forgot, you can go to that object’s code to figure it out.

I’m referring to a Scratch feature where you can select a color from the stage kinda simply by moving your picker onto the color and clicking it

Unless you used a set random color block

Maybe “set color (random), get color (preset color)“ ?

set var((Self)color) to random(1 to 26) // 26 or how many colors there are I forget
set color var((Self)color)

How? Why not show how it can be done?

Monkey {
  Set variable self(color) to 1 // dark purple 
} 
Gorilla {
    When self bumps Monkey
       If monkey(color) = 1 {
  Destroy 
}

}

for hsb colors it’d be hard

Setting color to a variable. This isn’t possible w/ clones though

How isn’t it?

What if for example you wanted to make a color picker in an art pad without using clones? How would you do it without this block?

Without clones? U would have each square set color to h(self(h)) s(self(s)) b(self(b)).
Then a general rule, set (h) to (self(h)) and so on with hsb
Then have the drawer draw in the color h s b

It would be useful for things like making the get color feature in this art pad with a regular art pad that doesn’t have an object for each trail.

If this was true then you can actually pixelate stuff on the screen
Even the whole screen
((Self)color)
((Self)sensed color)
