What's with all these short posts?
I still haven't tried it yet but I've downloaded the files at least.

What are all the kinds of blocks you have in this game?

What are all the kinds of blocks you have in this game?

solid
naturally generated
can't be used to build
unbreakable
currently unused

from id 0 to id 15:
air, wood, bedrock, leaves, planks, dirt, stone, cobblestone, iron ore, sand(can fall), ladder, water, lava, TNT(doesn't work yet), solid object, fluid object

What about a 256x64 world instead of 128x128? I don't remember if Minecraft needs this much depth and it would leave more space to build stuff. Or maybe 192x96?

128 is what the old minecraft used (now it's 256), so that should deffinately give you enough height. And the program itself doesn't use much RAM so right now a world of the size 128*300 blocks can fit in RAM, together with the program. So what fits in RAM isn't the problem right now. And too see if 128 is a good limit, then you must be able to fully play it, and for that it is in a too early state. What I mean with that is: I'm going to make this game fully functional first, so I'll imediately know if the world size is good or not.

That's because when you reach the edges of the screen, the blocks in the edit buffer (the blocks that you see) are copied to the world and the blocks which are on an other location are loaded. this makes the part of the world that you can see shift by 8 pixels, and to make sure the player won't be stuck in blocks, the player moves 8 blocks as well. This causes the bad scrolling. I will probably once implement smooth scrolling, but I don't really know how to do that yet. I'm already glad the tilemap fully works and has collision checking and scrolling.

Since you all wanted it:


I hope you like it. It was hard to get it to work.

progress went slowly because the OS ate my source files a few times, but here's a small update: the world generation now generates a hilly landscape instaed of the flat landscape with a few block at higher and lower coordinates, the bug that made trees sometimes spawn next to eachother and overlap has been solved, and large narrow veins of iron ore are generated. The long narrow shape isn't intended, the blocks are placed randomly, but somehow they often group together in veins. That's it. I hope you enjoy.

everyone why reads this thread seems to be addicted to screenshots...

Here's one:
the diagonal line of dirt is a bug, and I haven't been able to find the cause of it. 1+ for who does find it

This looks awesome!
(especially the scrolling)
I think that you might want to add a line between the world and the inventory...

Great job!
