- Box2C_Angry_Nerds_Game_SFML_installer.exe is an installer for Angry Nerds, the best demo so far for the UDF
- Box2C.au3 is the Box2D UDF itself, containing the Box2D / Box2C functions for AutoIT
- Box2C_linear_forces_test_SFML.exe is a test of Box2D linear forces using AutoIT and SFML
- Box2C_angular_forces_test_SFML.exe is a test of Box2D angular forces using AutoIT and SFML
- Box2C_speed_test_SFML.exe is a speed test using AutoIT and SFML
- Box2C_speed_test_Irrlicht.exe is a speed test using AutoIT and Irrlicht
- Box2C_speed_test_D2D.exe is a speed test using AutoIT and Direct 2D
- Box2C_speed_test_GDIPlus.exe is a speed test using AutoIT and GDI+
- the *.au3 files are the AutoIT scripts of the same name as the exe files above
- the *.gif and *.png files are the sprites / images used in the tests
- the *.dll files are the graphic engine libraries, and also the Box2C libraries
You can run any of the executables (exe files) above to test the UDF. The Angry Nerds game demo should play similar to this YouTube video:
The four speed tests will test the performance of the UDF against four popular graphics engines, as follows.
| Filename | Test |
|---|---|
| Box2C_speed_test_SFML.exe | Tests the SFML graphics engine with the Box2D UDF |
| Box2C_speed_test_Irrlicht.exe | Tests the Irrlicht graphics engine with the Box2D UDF |
| Box2C_speed_test_D2D.exe | Tests the Direct 2D graphics engine with the Box2D UDF |
| Box2C_speed_test_GDIPlus.exe | Tests the GDI+ graphics engine with the Box2D UDF |
Follow the prompts in the displayed GUI on how to conduct the test.
SFML (Box2C_speed_test_SFML.exe) should provide the best performance.
FPS readings are not limited.
