The nice thing about our collision DLL is that you don't need to know how to use DLL's at all. Just follow the instructions in the ReadMe.txt file in the download package. This is something that needs to be made clear on our website because people see the word "DLL" and think "woah, that's gonna be way hard to use because I don't understand how to plug DLL's in"
To use our collision DLL the only thing you need to know is there is a file called "NGCollision.dll" and you must copy it to the same place where your EXE is. That's it. And this info is covered in the ReadMe.txt file.
DarkBasic Classic allows you to use DLL's if you have the enhancement pack installed.
This enhancment pack is available here:
