Minecraft-like World

[Kelebrindae]

Hi,

I've made a little minecraft clone. Sorry I've took so long before posting it here, but I was trying to pinpoint and fix a bug that was preventing it to cross-compile on x86 and x64... (see here: http://www.purebasic.fr/english/viewtop ... =4&t=60433

The "game" is in a very early stage:
- The world is procedurally generated on-the-fly as you walk around, and saved when you quit.
- You can dig and build, but there's still very few block types available.
- Water and lava exist, but are not really managed (they don't flow).
- Only one biome (rolling hills).
- No monsters or animals, but there's still bugs aplenty...

Code and resources are in the zip below, because the sources are too big to fit in a forum post
http://keleb.free.fr/codecorner/downloa ... clone2.zip

Controls:
- Left-click to dig / right-click to build;
- E/R to select a building block;
- G to switch on/off ghost mode (you can fly and pass through walls)
- Ctrl and arrows to jump and move.

Use the "#VIEWDIST" (line 43) constant to adjust the drawing distance if FPS are too low, and don't forget to turn the debugger off.

A last precision: I've used an octree structure to store the chunks' datas in memory (see an exemple code here: http://www.purebasic.fr/french/viewtopi ... 13&t=14123) ; I'm not sure it's an optimal solution and it could easily be replaced by standard arrays[x,y,z]...

Have fun!

very nice clone of minecraft and nice demo for pure basic 3D.
And thx for the source code.

Some notes: Some times the word is rendered to slow or no longer, so the exe chashes.
Here the last screen befor it crashes:

Pretty sweet, thank you for sharing!

Guess I need Pb 5.3?
"Line 802: ClipOutput() is not a function, array, list, map or macro."

edit: no, your header says 5.21, I have 5.22 LTS

thanks Kelebrindae , i like the procedurally generated things
it works in pb 5.30. regarding line 3 of the source it said "PB version: 5.21". the ClipOutPut seems not part of 5.21 but it is part of 5.30

@Kelebrindae
That is some nice work you've done.
I've only skimmed the code for now and it's truly some advanced coding.
I won't even pretend to understand your code. It surely requires a LOT
of examination and isolated testing, before it will make any sense to me.

Well done and thank you.

ok, I installed PB 5.3. After asking for a seed the program crashes with the usual non-descriptive Windows error message.

try running the octreeWorld_v2-7.pb which are inside the folder mineclone, most likely you run the octreeWorld_v2-7.pb which are outside mineclone which are not related
as DK_PETER said it is an advanced example with issues related to computer science subjects, i have no idea how it works. may be in the future

In my opinion it's hard to build something because you don't really know where the block will go. Also inside a cave it's stuttering a lot. But apart from that very impressive work you've done there - I'd love to see this getting improved as it seems to have great potential!

Thanks, yeah it seemd logical to run the top most code and not something from a subfolder^^

@c4s: Yeah, the building is a lot different from minecraft. The distance between you and the block your place is pretty much always the same (which means you can place blocks in the air). It's a bit tough to get used to, when you're used to minecraft, but once you figure it out, you can build.

Well, the controls are kinda weird. I prefer WASD,Space instead of Cursor/Arrow and Ctrl/Shift or whatever, especially since you cycle through building blocks with 'E'

[Kelebrindae]

First, thanks a lot for your kind comments!

Second: Sorry for the problems you encountered, you are absolutly right...
This is more a test project that got out of control and took me way too much time, actually. I was just wondering how the whole "procedurally generated block world" was working, and if it can be done in PB => that's why it lacks a bit of polish...

@Derren:
I screwed up when I've done the zip file: When I added the sources, I didn't checked they were in the correct folder. I've fixed it and uploaded the correct version, with the pb files at the right place and all. Sorry!

I understand the controls may seem a little awkward if you're more accustomed to the "WASD" pattern. Fortunately, it's easy to modify: the "KeyboardPushed" are all located from line 2000 to line 2055, and are sufficiently commented so you know what to change.

@AppliPi:
Yes, it's v5.30 only, due to ClipOutput and other small things; the headers comments are fixed too.

@c4s:
The stuttering can (perhaps) be fixed by adjusting the #VIEWDIST constant. And yes, the digging/building mechanisms are somewhat unpractical; G-Rom told me so already, and I totally agree. I didn't play Minecraft a lot (just once or twice) and I only know it by watching my kids use it...

@All:
Well, I'm really sorry, but I don't think I'll update the code anymore: As I said, it was more a test than anything else, and it would need a lot of time and modifications to make it work really right (it's more "messy" than "advanced coding"). But I'll gladly answer any question if anyone want to reuse this code or any part of it.

I'm not a Minecraft dude..Waaaay too old for that - even my kids are too old (highschool).
Just a small note: Messy code IS certainly 'advanced code'.
Your code ain't that bad and you've created some nice tricks to make it work.
Your macros and some of your procedures threw me off guard, when I first skimmed your code.
You've shown, that creating something big isn't a problem at all for PB and that is a VERY good thing.
It's nice to see ideas and problem solving realized in (for me) unexpected ways.

Best regards
Peter

I know a lot of people older than that playing around with Minecraft (no life?). Did you try ? I did and I understand why, even if I really don't have (and don't want to take) the time.

Hey Djes.
I'm forced to play it, since I work with teenagers on a daily basis. My own kids don't play it.
The kids I work with are cheating like crazy - flying around - building large objects with a constant full inventory.

Yes, it's interesting, isn't it ? As if this feeling of cheating was something giving value to the play. However, everybody is cheating, so it's not cheat anymore ! But it's not as simple. Some times ago, I bought a card play to my child, where everybody was forced to cheat. He hated that ! But he loves minecraft...
