The rebirth of CCEmu

This is a completely new emulator written from scratch, as a 'revival' of my original emulator CCEmu,
It's written in Java and makes use of the ComputerCraft jar.
It also uses the LibGDX library for the graphics and user interfaces.
Screenshots: HERE

How to manually add a wireless modem:

Spoiler

Set the peripheral type value for the desired side to be "WirelessModem" in the computers settings file (DATA_DIR/sessions/SESSION_NAME/computer/ID.json).
Like this, replacing SIDE with the desired side:

{
...,
"side-data" : {
...,
"SIDE" : {
"peripheral" : {
"type" : "WirelessModem"
},
...
}
}
}

NOTE: The ellipsis here represents the rest of the content of the file, for brevity's sake. So DO NOT replace the entire file with the above snippet.

How to manually set the data directory:

Spoiler

You can configure the data directory by specifying the 'com.xtansia.ccemu.path' jvm system property when running the launcher.
e.g.
java -Dcom.xtansia.ccemu.path="local_data" -jar ccemuredux-launcher.jar
Will set the data directory to 'local_data' in the current working directory.

The data directory is located at:
Windows: %APPDATA%\.ccemuredux
Linux: ~/.ccemuredux
OSX: ~/Library/Application Support/ccemuredux

Nice! Good to see a nice emulator that uses the jar and LuaJ. Will it be open source?

//offtopic: Also, are those Windows 8 windows, or some Linux distro, or something else entirely? What gives them that gradient effect?

I'm definitely looking into making it open source, but due to how ComputerCraft is 'licensed' I would most likely not be able to open source the couple classes that interact with it

//offtopic: Yeah it's windows 8, I have a theme installed which makes them look like that, Snowy8

Looks nice!

Just a few questions:

- Is it 1.6 (or even better, can you add a thing to switch versions)
- With the ComputerCraft.jar, what's the limiting factors preventing you from using it. Does the new mod EULA change anything. Also, wouldn't your permission from Dan for 1.0 carry on to 2.0?
- How are you drawing the screen, as I often use emulators on battery power I don't really want it to be redrawing everything 60 times a second. Maybe only drawing pixel changes (i.e. when you call term.write)

But yea, looks good, looking forward to the release!

1. Yes it is using 1.63 currently, but I may look into a feature like that
2. I have no clue about the EULA, but dan200 doesn't allow redistribution of CC except for modpacks without express permission, as for the 1.0->2.0, it's effectively a brand new application and when I discussed the original with dan, he said it only applied to that app, and if to ask him first about future projects.
3. It is continuous render, I will look into doing non-continuous render mode, but no guarantees on how well that will go

[awsmazinggenius]

One simple (but not the best way) way of doing it that I use in my CC programs is setting a variable to true when anything on the screen has potentially changed (eg term.write("") will still flag it) and if so redraw. It isn't the best solution, but it works.

EDIT will a system where the user supplies the CC.jar work?

I can think of ways to do it, Will definitely look into it more in depth at some point

Yeah I could do that fairly easily, probably wouldn't be too robust, but I could definitely throw something together

[oeed]

The other thing you could look in to is to download the jar directly from the source Dan gives, so just download the jar directly from http://www.curseforg...erCraft1.63.jar

That's not really redistributing. But yea, the best would be to just talk to Dan about it.

What could this mean ;P

You search the filesystem for the user's own computercraft.jar?

I really don't get why people bother with this "What could this mean??!??!?!(one)" crap. It's just arrogant and annoying in my mind.

Well I'm sorry to have bothered you sir

[apemanzilla]

Looking good so far! Glad to see ccemu coming back!

[Csstform]

I played around with an earlier version, it's very smooth.

[theoriginalbit]

OS X support? or only Windows this time?

/Should/ work on Windows, OSX and Linux
Theoretically /could/ work on android too but would only really be feasible on a tablet and using a physical keyboard. <- Emphasis on the theoretically

[ardera]

Beautiful! Still using CCEmu, looking forward to this!

[awsmazinggenius]

Yeah, agree with oeed that something should be implemented. Often I find myself with my MacBook Air in places with no/crappy Wi-Fi, so I'm on battery and already using my phone's Personal Hotspot.

Non-constant render mode is on my todo list,
And I'm currently trying to contact dan about permission and how best to go about the computercraft jar

If I were you, I'd try to implement support for major versions (1.5, 1.6) and have the user provide the jar for whatever version they want to emulate.
