Question:
Is there any benefit to declaring variables, even if they are "empty" before the main program loop? I often throw a variable in somewhere as I go. This is actually a compiler question, I guess.

If it was c++, then yes.. it can make a difference.

In darkbasic, i havent really found any reason to, besides making your code look a little nicer..

ie..

playerone_obj = 1
load object "playerone.x",playerone_obj

In this sense, it's easier to know what's going on with your code instead of having numbers

I guess if they ever get around to adding forced variable declaration you won't have to change a lot of code to take advantage or it. Also the $ and # characters often make variable names more difficult to type.


it's cool to hate

Unless it doesnt start out at 0, then there's no big difference really, on the contrary, it might actually HELP a bit. Because if you only "define" the variable when you're using it, its one less variable for the compiler to keep track of .
