Minecraft 2D on HP Prime
« on: February 24, 2017, 10:45:00 pm »
Hello everyone!

Here is a game I made for the HP Prime calculator. It is based on the popular game minecraft by mojang and even contains the real textures:



I am looking forward to any suggestions :)

Best regards,
David

Heya and welcome here. :) This looks very polished so far, that's for sure. @alexgt was working on his own MC clone but he discontinued it D:. By the way, how do you store the map data? I notice that you are loading the map by small chunks (with some loading at the edges) so I was curious. Can we use the numpad to destroy blocks (eg 4 to destroy the block right to the left of the character and 1 for the block just above)

The HP Prime is an incredible machine in terms of programming. Even with the on-calc language the games can rival CE ASM/C/ICE speed O.O

The world is saved in a graphics buffer. Every block has a specific color and every pixel represents one block. With these colors the blocks are indentified when drawning a chunk.
I will try out the numpad controls. The Problem is that i will have to check all the keys for input in the games main loop every time :/

Ah I see. Thanks for the info. Would it be hard to make the game so that each chunk is bigger or would it cause memory problems/lag? And yeah checking all keys might cause some slowdowns, although given the speed of the HP PPL language, it probably won't be too bad I think.

You're pretty much giving us your fingerprints with that video, something you should avoid at all cost  :ninja:
Also you used bedrock instead of stone in ur map... a block that is not destroyable in the original minecraft (you destroy it in ur demo)

other than that it looks really promising :)
Can Trees regrow and is there water as well? :)

It would be really cool if there were smooth (maybe even italic) borders between different biomes, not just a vertical cut ;)

Most likely it was scrubbed by mojang and taken down for copyright infringement?

Actually, now that you mention it, I recall reading before that the reason why @Vogtinator used a different texture pack in Crafti was because Mojang was even worse than Nintendo when it came to copyright nazism, so if someone wanted to do a Minecraft clone he really had to make sure to not use the original graphics or music.
