Gee, your only two contributions to this forum have been asking for something and whining about the thread? You think the quality of the people on this forums isn't up to your standards?
That's the sad truth. It's only going to become more common as time goes on. People just jump into making their games without bothering to figure out, or at least get a basic understanding of, how it all works. Then they just expect that everyone else can just bail them out. There are so few developers nowadays that understand that they'll be mostly alone on their project. No one is going to hold their hand all the way on it. Few people actually want to do the hard work that's involved with making a game - they just want to be popular.
This error was shown after I replaced the PBS files and battlers with that of Gen 6:
So, er, help please?
Believe it or not, the error messages actually tell you what's wrong. They're not just there to say that you've screwed up. All those words have a meaning. It tells you where the error is, and points you to where the error occurred.
In this case, the problem is that the constant PBColors is not initialized. Pretty easy to figure that out. The error occurred in the script section "Compiler" on lines 1680, 4098, and 4212. PBColors is on line 1680, which is in the def for pbCompilePokemonData. Since it was uninitialized, pbCompilePokemonData was erroneous. This in turn caused an error for the def pbCompileAllData on line 4098 when it referred back to the previous def. Which in turn caused an error on line 4212 when the def was referred to again.
I think.
I have little scripting knowledge, but that would be my best assessment of exactly what's wrong and an explanation of the error message. Just so you'll know for the future.
As for fixing it, well, all I can recommend is making sure that you're on the very latest version of Essentials, and that you updated your game correctly, and that you followed all of the installation instructions correctly. That's a huge source of problems - people either aren't fully up to date, or they just don't follow instructions that well.
