C++ (Cpp) GetUpdateFrame Examples

Example #1

File: main.cpp Project: brizee/honours

// "main" is the S3E entry point
int main()

        // block until the next frame (don't render unless at
        // least one update has occurred)

        // must call update once per frame

    // clear up game object
