Eng:Scramble



Scramble is a Scratch Extension that allows users to create their own blocks for Scratch, and was written by Hardmath123. It is written in HTML and JavaScript. The images were created by Joeman592, and meew0 and Pecola1 thought up many ideas for it. As of now, Scramble is not being developed.

Getting the source code
To develop Scramble (2.0), you will need the source code, which comes bundled in the Scramble 2-0 folder, named Source Code. It is recommended to make a duplicate file with the original code, in case you destroy it beyond repair. You can also get the Source Code by right-clicking anywhere on the page (besides text boxes), and choosing view source.

Running a Scramble Mod
Assuming you have made a Scramble mod in a plaintext document like TextEdit or Notepad, use the following instructions to run it: Double-click ScrambleModSource.html to view your document. You will need to do this whenever you make a change. To make a version where you do not need to do this whenever you make an edit:
 * Save the file as 'ScrambleModSource.txt'
 * Save a duplicate as 'ScrambleModSource.html'
 * Save the file as 'ScrambleModSourceEditable.html', but do not close the .txt file.
 * Open this file. You now have two windows of the same file.
 * Make a change in the .txt window and press control+S to view it in the web browser window. Note: closing the .txt window will make the file un-editable again, so leave them both open until you're done. Otherwise, save the source as a .txt, and do the above whenever you need to edit it.

Creating a Scramble Command
Though Scramble has a "insert custom command" feature, it may get tedious to do that over and over. To add a command, do the following:


 * First, note the following abbreviations used in the codes. Whenever you see these, insert the stuff described below.
 * +++++ is the block's name. Make it short, and made of only letters. E.g. moveBackwards
 * ///// is the block's text. That is the text you see that describes what the block does, and is visible on the main screen. E.g. Move the sprite backwards.
 * is the block's squeak coding, what it actually does. When you insert coding, use the following rules:
 * Codes are enclosed in double-quotes ( " )
 * Inputs are named tempInputA, tempInputB, and tempInputC. Inputs are added like this:
 * "coding"+tempInputA+" more coding"
 * "self forward: "+tempInputA+"."
 * - is the coding translated from Squeak into English, e.g.: "Move "+tempInputA+" steps back" "
 * >>>>> is what the input asks for, like 'How far should it move backwards?'. Remember to include the data types you can include.


 * Now, open up the source code. Scroll down to the following line:

  Move the sprite forwards Turn the sprite [clockwise] Set the position of the sprite Set the direction of the sprite Change the x position of the sprite Change the y position of the sprite Set a variable to the x position Set a variable to the y position Set a variable to the direction
 * Now, you will see a list of the types of blocks, encased in, and followed by some code. For motion, it is:
 * Scroll to the type you need. Go under the . Paste in the following code and fill in the abbreviations:



/////

/*Motion /*Type <pre style="overflow:auto"> if (blockName=="add") {		tempInputA=prompt(">>>>>") tempInputB=prompt(">>>>>") tempInputC=prompt(">>>>>") document.getElementById("currentBlock").value=||||| document.getElementById("currentBlockSimple").value=- }
 * This is called the ScrambleSpec, and is what defines the block.
 * Now, scroll down to:
 * Look for your block type in this format:
 * Insert this snippet:
 * If you need only 1 input, delete the 4th and 5th lines.
 * If you need no inputs, delete the 3rd 4th and 5th lines.
 * If you need only 2 inputs, delete the 5th line.
 * Congratulations! You have made a new command! Try it out.
