I'm not really sure why that's happening. Try landing on a platform or something

Fixing collision bugs is always a painful task ... Finally tracked down this one. :)

Code: Select all

-		if(EmptyContent(pMod->theModel))
+		if(EmptyContent(pMod->theModel) == RGF_SUCCESS)
			return RGF_EMPTY;

Was just passing by and had to comment... This bug was thanks to the antique way of code the RF source is written in... (basically c style - if something goes wrong you pass the user of your function an error number and let them handle it)... thus demanding that we always test for RGF_SUCCESS... (since there rarely ever are any boolean functions)... which can easily lead to mistakes being made while programming because you didn't test for RGF_SUCCESS.

The problem arises because every nonzero number gets converted to true... and that means that any error code you give will translate to "success" in the if statement...

Exceptions or even inside-function-error-handling would be better. However, it is not worth rewriting RF for this. Heck, no. :lol:
I guess this style stems from the Genesis engine being written in pure C. (Also, i don't know how people programmed when RF was written... might be just an "old way" of programming things)
Everyone can see the difficult, but only the wise can see the simple.
