How to use cloud data to make a multiplayer game(online)

iceninja1234567

1. Make these 5 variables:

(player 1 x)

(player 1 y)

(player 2 x)

(player 2 y)

(player #)

iceninja1234567

2 make the following script:

when [J] key pressed

ask [Number:] and wait

set [player #] to (answer)

iceninja1234567

I`ll send the rest later

but for now:

when green flag clicked
say [ICENINJA1234567 IS EPIC!]

Basically, to make a multiplayer game, you need four cloud variables (minimum, you can add more if you want extra features):

PlayerOneX
PlayerOneY
PlayerTwoX
PlayerTwoY

when green flag clicked
forever
    set [PlayerOneX v] to ([x position v] of [PlayerOne v])
    set [PlayerOneY v] to ([y position v] of [PlayerOne v])
    set [PlayerTwoX v] to ([x position v] of [PlayerTwo v])
    set [PlayerTwoY v] to ([y position v] of [PlayerTwo v])
end
Then you should update display the PlayerOne and PlayerTwo sprites on the screen by pulling the X and Y positions from the cloud variables. I hope this helped you![/quote]

Ok but can you make people able to join in?

Dear fellow Scratchers,
How do you make a multiplayer game where characters can interact with each other? I looked inside griffpatch's multiplayer platformer game, but it
still didn't help. Griffpatch said It is hard to make a multiplayer game. Anyone help please!

all the ways are hard griffpatch's way is the best easiest way.

griffpatch's cloud variable game does not use Player X and Y positions as cloud data

They are right, but you can also save a world by a name and have a server button. When you click on it, use a join block
to join the server, which will be a world identified by the variable server.

when this sprite clicked(join (server) )
Cloud variables are really important to, but at this time, you have to assign each player an ID and add the ID to the cloud variable/ list.
Example:
when green flag clicked
if <[players on list] = [1]> then
 set [myself] to  [1]
insert [1] at (player 1) of [list of players]  
end
else
((set myself to number of players on [list of players]) + (1))
insert [myself] at (((number of players on [list of players]) + (1))) of [list of players]
Of course, you would have to make more variables so that you wouldn't be saying:

((set myself to number of players on
) + (1))
insert at (((number of players on ) + (1))) of
The cloud data is back to normal, so now you don't need to assign each player an ID. You could just do this:
when green flag clicked
if <[players on list] = 1> then
add myself to [list of players]   
end
else
insert [myself] at (((number of players on [list of players]) + (1))) of [list of players]

And how to get off so that other players can join?

ppl its easy to make online multiplayer it only takes 4 scripts minimum just see http://scratch.mit.edu/projects/22968899/
its kinda missing lots of features other multiplayers have but it still works

KronosTheMaster

Here's a useful tip: the maximum length of a cloud variable is 10240 digits, and you can have up to 10 cloud variables on each project. See http://scratch.mit.edu/projects/22996518/ as an example.

Yeah, I don't go on the forums that much

:(

http://scratch.mit.edu/projects/22752145/here U made a game that can do it but you must remix it.

Well thanks for trying to explain but how exactaly do i store all of the players x and y?

I did some tests for a game I'm making, and it seems that clones create their own variables. That is, if you have one square per player, and cloud data to track that players x and y, you can have the square clone itself and each clone will have individual variables.

The hard part is getting each clone to respond to separate input. But it may be easier than I think – I haven't tested this exact problem.

Where do you find all those blocks?

I know how. Because I'm working on one

So, you make one cloud variable for each player. In that cloud variable, you have numbers for their X, Y, HP, and if their attacking or not. Then you make the characters and wire it together. If you look at this project http://scratch.mit.edu/projects/18992128/ it might help. In this project, I laid it out nice and easy so that the cloud variables are individual instead of all in one. AND IT WORKS! I'll add you to the beta (more like alpha) testers if you want. Hope it helped! If you need more specific information, just let me know!

LONG LIVE THE DREAMCAST!!!!!

There's an easier way of doing that but it would limit the amount of players you could have.

Try reading this post by me. I have made my own online multiplayer project that works, so I know a little about the topic. Maybe it will be a bit easier to understand. The exact scripting is not given in the post, it was to explain how to it basically works.

Thank you so much for that information! That is really helpful. I have been searching for that information for a really long time, because my multiplayer engine has really long cloud variables. The longest in there is 3000, but now I know it can go way bigger.

I've also been wondering how to make a cloud game where muliple players can join instead of just, like, 2 players, how do I do this?

its not. make a list that says (if you were doing cannons) cannon x and another that says cannon y. then, after spawning, add x to list cannon x(use the built-in x and y position) and add y to cannon y and bam! there you go

supercreeper2005

To make multiplayer, make a script that set's player 1/2 x to a cloud variable. Then when a key pressed (right) , change the variable rather than the X position. Make player 1 to use WASD and player 2 use arrow keys.
