How to change window title and "About Scratch" menu and it's link in the Help menu in Scratch 1.4?

stasiu2015

I'm making a 1.4 mod, and I'm making the About Scratch menu have all references to Scratch removed except for “Based on Scratch by the MIT Media Lab”, but when I open the System Browser and go to aboutScratch, when I try to edit it and press accept, it gives me various errors about the contents of the About menu like thinking some words are VARIABLES, how to fix it, and also how to change it's link in the Help menu and the window title, it's an IMAGE file also

You probably just made a syntax error; if you post your modified aboutScratch method here (in a [code] tag) and someone will be able to look at it

Also if you want to change what the menu item says from “About Scratch,” edit the method ScratchFrameMorph>>helpMenu:.

	menu add: 'About Scratch' action: #aboutScratch.

(it might say t1 rather than menu for you; then you should probably get the Scratch source code or Scratch.changes)

You just have one unnecessary apostrophe at the end of the line here. That closes the (multi-line) string literal.

The code that sets the window title is in the updateProjectName method of ScratchFrameMorph.

Also, how to change the default text in the

(join [hello ] [world])

(letter () of [world])

(length of [world])

blocks

That's defined in the blockSpecs method of ScriptableScratchMorph.

Yes, but when I change it, it still says hello world

They're both predefined arguments for the block specs in ScriptableScratchMorph (instance) > defaultArgsFor:

    #concatenate:with: = sel ifTrue: [
        defaultArgs _ Array with: 'hello ' localized with: 'world' localized].

    ... (editor's note: irrelevant)

    #letter:of: = sel ifTrue: [
        defaultArgs _ Array with: 1 with: 'world' localized].

    #stringLength: = sel ifTrue: [
        defaultArgs _ Array with: 'world' localized].

If you want to change the ‘hello world’ arguments you'll have to change them within this function since these override the defined arguments in all three blockSpecs
