How to make a multiplayer sandbox building game like minecraft

nwolf2012

I'd like to make a multiplayer 2D Minecraft where you can also play singleplayer and in multiplayer, you choose who's game to join.
Example:

generate world

join server

disconnect from server

say [Woof!:P] in chat

Well I cant tell you the exact scripts but single player would be some type of generating world with stamps or maybe clones. Then you would need a player sprite with detection to the environment. You would need clones for all of the mobs and some sort of random ai patterns for them such as a timer for when they should move. You would also need a brightness system where it would darken blocks that have no source of light near them. This is for generating worlds for mutliplayer and single player. Making a sever is extremely difficult. Very few people have done it. You would need a host for the sever and some cloud lists. To make a cloud list you need a cloud variable and some other block “magic”. What you are trying to do is very complicated so yeah. You should try something more basic before working with multiplayer games.

Lots of cloud variables

Multiplayer games are a very difficult thing to do. I've tried, and failed many times. I still haven't successfully made one. If you want the game to create and host servers, that is VERY hard to do. I'm not even sure if its possible. But, you can make it so a game has slots. Once a slot is free, another person can enter. You would just have to figure out how to make it detect if a person is come or gone. I hope I helped.

@brandingdavid told me that java is so confusing. But python is OK; it's like a programming language I already know called php.

That's a bit too ambitious…
You see, you can only use cloud integers (you can only store numbers on the cloud, text won't work).

To generate a world, the way to do it would be to:
1. Create random seed
2. Use seed to create map
3. Store entire map in cloud variable (Sorry, no lists! BTW, you would need to prepare for more than one player).
And no, there are no built-in blocks which can do that directly.

ONLINE multiplayer chat…
Plus, the Scratch Team discourages that, unless you want to frustrate yourself by creating a safe chat (chat with pre-determined words).

I want to know how to make a multiplayer game like Pixeltown. But I don't know how to use cloud data to do that. #HELPME
