i'm a very newbie

[logic_sci]

i look at some tutorial of this engine and i saw something that i confuse
,why it don't have something like "delete someptr" i saw only
device->closedevice();
is it fully clear resources that loaded ?

and i want to know about this engine ,
if i use this engine to write commercial game .
can i use it ? and if i can ,what i "must do" when i use this engine ?
thank in advance

you should read the docu for the "drop"-Command.
There Niko wrote it clearly. You only have to drop things that are created with a "create"-command.

With removeTexture you can remove textures before closedevice, but closedevice would do it at the end for you.
