Site for deploying the Reduct(-redux) game

For new features:

1. New levels - select array-booleans (after Ctrl + F8)
2. Autograder/Oracle (node with a ship) - Most levels on "recursion-basics".
3. Level progression (hamburger button - top right)
4. Make your own level - Press Ctrl + F8 and select 'play' from dropdown menu NOTE - you can add a node to a previously defined level as well (not necessarily 'play')

Writing your own level

Adding a node:

Press Ctrl + F11 to open the 'Add Node' dialogue box. It will ask for the string representation of the node and the segment where the node is to be placed - 'goal', 'toolbox' or 'board'. Press ENTER when you have completed both the fields. It saves previously defined nodes for future use.

Defining the node string:

This is the same as writing the node string in a csv file. Defining new features (marked with a $$) need some special care explained later. Some examples:
Definig function
function addOne (x) { return (x) + 1; }
function myRepeat(num, func, value){ return num == 0 ? _ : func(myRepeat(_, func));}

Defining if blocks
_ == _ ? 5 : 4
num => num == addOne(5) ? true : false

Defining references($$) You can use previously defined references directly anywhere on board or toolbox.
addOne
doNothing
etc...
NOTE - if you are defining references in toolbox with __unlimited tag, you need to add the corresponding tag in the csv file when you download it.

Defining autograder($$)
To define an autograder, you can use the following syntax:
__autograder(i) where i ranges in {0,...,4}
__autograder(0) is adversarial, i.e it will look for a pair where user defined function breaks. If no such pair exists, it returns the first pair at index 0.

-If you are defining an autograder(with index i), you should define a missing node _ in the goal at the ith position so that autograder can fill it later.

-If you are defining an autograder, you need to add input and output fields to csv manually. Using autograder(i) requires at least i input-output pairs to be defined in CSV.

When do you need to modify csv manually:

• Adding modifiers such as __unlimited, __argumentAnnotated to the nodes has to be done manually
• You need to define input and output lists manually in csv if you are using an autograder

Downloading CSV

When you are done making a level, press Ctrl + F8 and click on Capture State Graph. A pop up will be displayed asking you for a textGoal. Give a value to the textgoal (or leave it empty) and press ENTER. Your level will be downloaded.
