Winner's Dev Notes

Convert degrees and radians in Cocos2d-x Lua with math.pi formulas and reusable helpers for node rotation, trigonometry, directions, and angle calculations.

Implement a Cocos2d-x Lua string-split helper with string.find and string.sub that treats single or multi-character delimiters literally and returns an array.

Call Android Java from Cocos2d-x Lua, open a Facebook page through an app deep link when available, and fall back to the browser URL when necessary.

Learn Java if, else if, nested conditions, the ternary operator, and switch statements through syntax explanations and practical code examples.

Learn how Java expressions produce values, statements perform actions, and braces create blocks, with arithmetic, Boolean, short-circuit, and scope examples.

Learn Java arithmetic, assignment, comparison, logical, bitwise, shift, conditional, and instanceof operators, including short-circuit evaluation and precedence.

Understand all eight Java primitive types—byte, short, int, long, float, double, char, and boolean—with ranges, literals, defaults, and examples.

Learn Java variable declaration, initialization, naming, types, scope, and lifetime, including local variables, parameters, instance fields, static fields, and constants.

Learn Java syntax through HelloWorld, including class and source-file structure, the main method, case sensitivity, identifiers, comments, keywords, and naming conventions.

Compare Java System.out.print and System.out.println, including automatic line breaks, consecutive output formatting, string concatenation, and runnable console examples.
