I've written a few games in C where usually things are based around structures which hold different types of information, eg.

struct player
{
int x;
int y;
real health;
char *name;
};

sorta thing

Is there any way of doing this in db. There's obviously no built in way but is there a clever way of organising data to get the same sort of flexibility?

"DARKEDIT" has access to types which are cascaded back to arrays for classic.

lol giggles at other users.

couldn't find anything about that in the documentation - i'll dig around some more - thanks.

The TYPE command in the editor is, for most purposes, exactly the same as 'struct'. The source below just outlines a simple implementation of the command.

Your other option for creating your data is to use parallel arrays, whereby,
dim Player(2) = holds x,y and health data.
dim Player$(1) = holds name and (e.g.) weapon name data.

Oh, also, you'll be aware of how useful the 'C' command 'switch' can be. This is also implemented within DarkEDIT using the 'select' command.

Thanks, that's brilliant, just what I was looking for. I'd worked out that you could do it with parallel arrays but it's a bit of a do.

I saw there was a select command mimicking switch.

So... is there anything that works like a pointer?

Aha, Memblocks - right?

Types look like they could be extremely useful. Are there any good tutorials on them around?

Thanks.

I haven't found any yet, although if you can get your hands on a C book, look up structs. Most of the theory about using them is the same, you just have to translate the syntax.

fatmanfat:
I haven't got as far as working out memblocks yet, I thought I'd wait till I can afford DarkBASIC Pro and learn then. Pointers scare me anyway.

yes - i'm not sure that memblocks will do the trick.

i haven't had a lot of time to play dbc this week but i'm finding it quite frustrating to work around the clunkiness of basic.

pointers are scary when you first use them, but i found that if you forget about the theory and just concentrate on the use then they're not too bad. and they're incredibly useful - you can have things like an entity structure which includes a pointer to an animation structure. makes for nice neat code.

Yeah, I was starting to realise that the theory to pointers is more complicated than the application, thanx for the tip though.

I always think that BASIC feels a bit 'flimsy', like it'll break or slow down when pushed to the limits, and C++ just feels slicker somehow. Still, with DarkBASIC you can get a lot up and running very quickly.

I'm still looking for info on how to use memblocks and in what situations they are the best (quickest) option.

C : Don't even go there, this programme is just far too advanced for me.
C++ : An extreme amount of effort and work required for very little return.

I've tried to learn these languages, but there complexity bogged me down and was the reason I was put off being a programmer proffesionally.
Life's too short.
