Another simple J2E application that lets you create new episode files but this time also load and edit existing ones.

A simple little Tool with everything you need to make your own

Could be better, but could be worse.
Download recommended.

Tools like this have been around for a long time. This is the first to be put on j2o though.

I’d like to warn everyone who thinks of using this, of one particularly important fact. Especially because of this comment:

“ I hope evilmike makes some for his single players.”

Too many episode files will cause jj2 to crash on loading the episode menu. Know this before you think of making a custom j2e, and make sure you put a warning in the description of any episode that contains one. Personally, I advise against making one at all.

Because of this fact, I do not, and likely will never use a tool such as this. I had the option of doing so years ago and I deliberately chose against it.

This is the only tool publicly available on J2O (aside from J2E Creator by the same author) that provides the much needed functionality of creating and editing j2e files, so you kind of need it if you want to have custom episode files without writing your own software. So it was received well because it was software we needed. That is not to say it is a good tool for the job.

You open this up and you’re greeted with an awful, awful user interface that is hard to call an improvement over a console application. First thing you’ll do is probably try to open some file, either a j2e or a bmp, you’ll type in the file name (don’t count on a Windows file selection dialog), and you’ll be told that nope, that file doesn’t exist, because you’ve included the file extension like any sane person would do, but J2E Editor actually appends .j2e or .bmp to whatever you type in, so it just tried to open Home.j2e.j2e.

With some effort you get used to that and you load the bitmap you wanted. You know JJ2 uses palettes, so your bitmap already has the menu palette, so all that the software needs to do is take your indexed image and put it in a j2e file. Well, it won’t do that, because your menu palette is not the menu palette it wants. The menu palette it wants is in a file included with the software in a format that nothing opens. If you manage to open it, you can find out that the palette is blatantly wrong. Literally all you have to do to obtain the menu palette from the game is take a screenshot (F12 key) in 8-bit color mode and extract it from the file, so how the author managed to obtain his very discolored version of the palette escapes me. I sort of imagine that he tried to approximate it via trial and error until it more or less looked right.

But that shouldn’t matter, right? It can just take the bitmap, see that it’s indexed, and put it in the file as it is. No, what it will actually do is make sure the provided palette matches exactly, and perform color reduction if it doesn’t. Why? Just why? You take my picture crafted exactly for the menu palette and it’s ready for you to just put directly in a j2e file, all you have to do is zlib it, yet you have to convert it to your crappy wrong palette?

Writing text into prompts relies on key press events rather than character input events, and if you know what those two are, you should be cringing right about now. This means that handy functions like copy/paste will not work, long presses of a key will not produce multiple characters (including that you have to press backspace once for every character you want to delete), and what non-alphanumeric symbol you obtain by pressing a given button is very much dependent on your keyboard layout. Whenever I have to type in something like a dot, I just go through every symbol on my keyboard with and without shift because who knows which one will happen to produce a dot. This is an actual downgrade from a console application.

Oh, and here’s another fun fact, I wondered why I can’t edit the episode’s number in the list. So I looked into the readme, and apparently it’s the only thing that you interact with not by clicking on it like everything else in this program, but by pressing numpad plus and minus keys. Nothing indicates this, you just have to open the readme to find out. It was a matter of adding something like “±” to the user interface and it wasn’t done.

This is terrible software. It’s bad at interacting with the user, and it’s bad at its job of just taking some data and structuring it into a j2e file, but I guess the files it eventually produces are at least correct in the sense that JJ2 opens the j2e files and graphics software can open the bmp files it exports, so it’s not hopelessly useless.

Excellent does what it says it will do , and works 100%. And very easy to use. The only problem with it is the interface , it’s pretty ugly but thats not going to hold back a great programe like this.

So as it says it makes episode pictures on the main single player menu so you ill no longer have to go into home cooked for some of those impressive single players. I hope evilmike makes some for his single players.

Another good thing is if you have not stuck close to the pallete it will auto convert it for you , even tho sometimes arter effects won’t be so good but hey thats the only colours you can use anyway. There isn’t much more to do that simply save the images you made and save them into jj2 as j2e files.

Well it does what it says and it does work , and is a very good feature for any people who enjoy makeing single players , can finally have a image on the main screen of the work. The only thing holding this back a little is the ugly interface. So i reccomend you download this.

@evilmike ,I knew there was one earlyier than this , but maybe you could make some and tell people not to have too many , or maybe a jj2+ fix could sort it out. maybe. It’s still useful.

First bug, but now it’s fixed ;)
and it should work with 1.24.
It does for me.

And sorry for the bad input system.
The most important letters should work properly though.

Very Good Program
It works well and it does what it you said it does do,makes episodes excellently.
Also it will be very useful for people who want more style in their Single Player packs of levels.
I tested it myself and it works.
I l use always when making my Single Player Packs.
Thanks to it,the Single Player pack i m working on will be a huge success.

This is definately an improvement to your previous program. The only bad thing I see so far is the weird text codes. For example: you need to type Shift + the “+=” button to write a “?” and vice versa to write a “_”.
Also, when I click “filename” it doesn`t do anything. But other than that I think it rules supremely above the other one. Mainly also because you had to start all over again on the other one, and that you had no way to edit episodes. Which is BTW also very neat. And i`m not saying that other one wasn`t good or something, I think it was one of the best programs on J2O, it`s just that this is an upgrade to it.

Also the appearance looks at least three time as good. A window with pictures looks way more awesome than only a CMD text box.

So, good? Definately.
DR? Absolutely!
Improvement? HELL YEAH!
