@thenerd - Why do you do it that way instead of as a function? It would save you a lot of code.

True. I'm a big fan of select/case, but that probably isn't the best place to use it... The best way would be to have one engine loop that could handle all the levels, and like Grog has it just load the content at the end of levels. That way, you could eventually add levels without any hard coding.

I also have a horrible habit of using GOTO to exit from loops instead of exit.

The Using GOTO for EXIT thing isn't that uncommon really. It's not always convenient to exit the loop at the next instruction, so jumping out to a user defined location isn't the end of the world.

For stuff like the building levels, then it's a good idea to avoid hard coding them into the game as much as possible. See-> Separate Subroutines for Each Course

The whole GOTO thing has been done to death. Tutorial-About-GOTO


Hmm, I wonder what's coming in 2011?

I'm sure if I ever found a valid reason to use Goto, then I probably would use it.

However, It's not happened yet.

I also grew up with Goto, I taught myself to program on a ZX Spectrum; which used line numbers as well. That was amazingly frustrating at times.

Hmmm, but wouldn't you just use the BREAK command to exit the loop before the next instruction? I know that's what I use in C++ or PHP.

switch is the GOTO in sheeps clothing.... lol so really what your doing isnt much different... basically its a simplified encasulated goto... which is ok... lol. Thats when its ok to use. not when it gotos half way across you code.

As stated, the only ever use I've ever used GOTO for is for VB error trapping. It serves little purpose beyond that, as conditional statements in VB are by far the easiest things you will ever do.

Which reminds me, I don't know why people beat up on VB, I guess people hate things that are easy. I mostly use it for personal things like financial calculators anyway.

I just now realized I've had a typo in my signature for the past 3 years.

In nested loops there's often more than one pathway the programmer might want.

a)




b)

The first code snippet would only exit the first loop.

[EDIT] never mind...

about sharing source, when i read example snippets or examples on using shaders, it is very nested and highly skilled structure just to show "hey, looks how i'm skilled on making code so unreadable!"

goto is clear. go there. stop.
