The conditionals you use in if-statements and even while-loops are evaluated to boolean results. When your functions can return their results, it's easier to break data-producing computations into smaller steps.īoolean - A binary variable with two possible values: True and False. Return - A return statements lets a function compute a result value and return it to the place that called the function. Now with flags, students have a way of sending input to their programs: clicking a mouse plants a flag that the hero can respond to with the hero.findFlag() function. Up until now, students' CodeCombat programs haven't been interactive-there hasn't been real-time player input while the level is running.
You get to it by specifying the object, then a dot, then the name of the property, like item.pos.įlags - Real-time input devices. Property - Data about or belonging to an object.

Levels catering to basic arithmetic address how to use math as needed in order to perform different actions effectively.
Course 3 begins to ease the player into using math while coding. Skip or end while-loops with break and continue statmentsĬoncatenation - String concatenation is used to add two strings together with the string concatenation operator: +Īrithmetic - Addition, subtraction, multiplication, and division. Scope and Sequence ModuleĮxecute if-statements if one of two things are trueĮxecute if-statements if both of two things are trueĬombine x- and y-properties and arithmetic for movementĬode based on elapsed time and hero health This guide is written with Python-language classrooms in mind, but can easily be adapted for JavaScript. They also learn to work with time programmatically, and to manipulate their while-loops with the break and continue statements. Combining those with computer arithmetic and properties lets players finally explore relative movement, directing their hero to dynamic locations. The boolean equality, inequality, or, and and operators let them express compound conditionals. They then learn to use functions that return values, to break up computations into smaller pieces. Alongside properties, students unlock the additional game mechanic of real-time input handling with flags.
All things in CodeCombat are objects, (that's the "object" part of object-oriented programming,) and these things have accessible attributes, such as a Munchkin's position or a coin's value both are important to begin visualizing the internal structure of the objects that make up their game world.
Arithmetic will help players become more comfortable with using math in programming.

String concatenation will let players modify strings dynamically in their code to produce whatever text they want. On top of those, they'll get into more sophisticated operators and keywords. In this course, students will keep practicing their functions, events, and nested conditionals. Most of the differences in the programs the students want to write and the programs they know how to write start to fall away in Computer Science 3. Now that students have a solid foundation in the most useful types of control flow (conditionals, functions, and events), they're prepared to level up both their conditional logic skills and their control flow control.
