How do I use modules to speed up builds for game development?

C++ modules can significantly improve build times in game development by allowing parts of the codebase to be compiled separately, reducing the need for repetitive recompilation.

This is particularly useful in larger projects where header files can lead to lengthy compilation times. By using modules, developers can isolate changes and target re-compilation more efficiently.

Example Implementation

// Example of a basic C++ module export module Physics; // Declare a module named Physics export int add(int a, int b) { // Implement a function in the module return a + b; } // Main.cpp import Physics; // Import the Physics module int main() { int result = add(5, 3); return 0; }
