return *this;
-
this is a thing when i was studing C++
in the class function we use return *this; for get itself pointer
so maybe can use for this1
2
3hge->Effect_Free(snd);
hge->Texture_Free(tex);
hge->Texture_Free(quad.tex);
becomes1
2hge->Effect_Free(snd)->Texture_Free(tex)->Texture_Free(quad.tex
)
in one statement but in some cases will be long.
just an idea for share , thx

I'm not sure why you would want to do that. It just makes things less clear. And, since those methods don't return the hge pointer, it wouldn't work anyway.

Yes i know that doesn't work
but in the Begin C++ programming book
recomend this use , i just bring up that's idea,
but in fact i don't know that make less clear,i never have a
really project worked, so sorry my ignorance :oops:
but is there any posibility for use?
like tihs:
pFont->SetColor(ARGB(255,255,255,0))->SetScale(2.0); ??

Returning *this is generally only useful for things like operator overloads. That lets you do things like:
objA = objB + objC;
For general class methods, it really doesn't make sense to return something just for the sake of returning something. -
No need to apologize. You don't learn if you don't ask!
