Giving Scratch 3 "Inspect Element Surgery"!

chexbox

I decided to play with the inspector on firefox. Here's my what I learned:

Each block has a “hitbox”. It is a <rect> html svg element which opacity is usually 0.

I changed the font. It is amazing how many times the font is defined.

I made everything red! (font still changed)

Image switched with my own.

Scratch does not like small screens:

Share what you've learned about Scratch 3.0 and it's styling below!

I was able to make some blocks' name empty;
I deleted some elements trying to do this.

I'm trying to use inspect element to recreate “hacked blocks” in scratch 3.0. I was trying to make

if (answer) then

end

so that the password would be “true” and you could not find this by looking inside. I have not currently succeded, but I feel that I am getting close.

Run

document.querySelector("[class^=target-pane_target-pane]").classList.toggle("reversed"),document.querySelector("[class^=gui_flex-wrapper]").classList.toggle("reversed");

In your browser's console to swap the side of the editor

That doesn't do anything, there's no reversed class. Use

document.querySelector("[class^=target-pane_target-pane]").style.flexDirection = "row-reverse",document.querySelector("[class^=gui_flex-wrapper]").style.flexDirection = "row-reverse";

Instead.

I'm using this to help me make themes.

This might potientally help me make a Scratch 3 mod where the stage is on the left! Thanks!

Just added the swapping to Theme3, thanks JGames101!

can you do small blocks with this?

I have not gotten that to work.

The blocks are rendered using SVGs generated by JavaScript; even if you manage to update every single SVG, it'll all get reset if you don't update the JavaScript variables as well

So as far as I understood making the blocks smaller is difficult. But would it be possible to increase font size and weight within a block so that the block text is still readable when viewed in 50% size?

Increasing the font size and weight would increase the text width, but each text part (eg block labels and inputs) and the block width itself is dependent on the width of the text before it; increasing the width would result in overlapping and overflowing text

What you can do for hiding a password is translate a string to numbers and then do some sort of mathematic function that us hard to reverse on that number and then when the user enters a password it checks that aginst the actual encrypted version, that way it is very hard to crack

Take a look at this project I made ~2.5 years ago https://scratch-mit-edu.ezproxyberklee.flo.org/projects/135744907 , it does exactly what @staffordboys is saying.

The answer is 1. Binary code uses 1s and 0s. Computers use binary code as true & false. 1 = true.

Ha ha …. inspect is blocked on my (school) computer …. haha … *starts crying*
