Hi everyone,
I'm new to this forum (well, I've been lurking for a good few months now, just registered, though) and I've already got a question to throw out here. My main interest in Visual Basic is in game programming (I learned programming in C and C++, yet for some reason I've recently become obsessed with proving that Visual Basic can make top quality games) and I was hoping to expand my knowledge base a bit in an area where it is completely lacking - doing anything with hexagons.
I don't know how many of you have played computer games such as Heroes of Might and Magic (or any tabletop wargame that uses a hex board), but what I'm looking to do is make a simple 'game board' consisting of a number of hexes. Unfortunetly, I lack any knowledge on the subject and wouldn't even know where to start. If anyone could provide a good explanation of the math behind this I would be extremely appreciative. Please no source code, though. I'm not looking to copy someone elses work or to memorize code, I'm more interested in understanding the process.

Ok, first off, it's very possible to make games with vb, but you have better advantages making a good quality game in C++. But since you seem to want to proove it can be done with vb to, then you just need to be as stubborn as i am, since i've always tried to do games with VB, including such with elevated hextiles such as in settlers2.
mapping a hexagonal area is probably easiest done with a tilted view:
Code:
_____
\/\/\/
\/\/\/
\/\/\/
\/\/\/
whereas all tiles actually are triangle each even \/ and each odd /\. 6 of these forms a hexgon as you can see. The coordinates for each vertex is given by this formula:
pixelx=(x+y/2)*tilewidth
pixely=y*tileheight+heightoffset*elevation <-- this is if you need to have elevation.
To draw these you need to use either bitblt or Ddraw, Ddraw is probably the best if you want to have a good quality game, although using that you are using a lot more C++ implementations than with bitblt lol. well if you need more help just ask.

Hmmm.... yeah, I definetly see what you're saying. Thanks a lot for the help. My first program using your idea was kind of a mess (maybe I'm just a slow learning? hehe..), but then I revised it a bit and I'm off to a much better start. I managed to pretty much work out all the bugs I had in it and it looks like I've got my first working hex map program. Thanks a lot! ...
As for game programming in VB -- yeah, I've had my fair share of hurtles to get over, but I am a pretty stubborn guy and I've kept with it (satisfying my C++ addiction by writing tutorials for my soon to be launched website :)). I'm very familiar with using DX7 in C++, but I've come to understand that both DX7 and DX8 (which I just downloaded the full sdk for) have a good deal of Visual Basic support. Guess it's time to check eight out...
...anyway, thanks again for the help.

oh, you're familiar with using DX7 in C++, since were actually going in opposite direction, i know how to use DX7 in VB, and want to go on learning it in C++ and you on the other hand want to learn it in VB, i thought we might help each other ;) do you have ICQ or something^?
