TO QUICKLY MAKE RESOURCE PACK:
|
||||
1. make your changes to the files in '/lwjgl-rundir/resources'
|
||||
2. double click 'run.bat' on windows, or run './run_unix.sh' in terminal on mac
|
||||
3. copy 'assets.epk from '/javascript' to your web directory
|
||||
|
||||
To manually use the CompilePackage.jar on a custom directory, run the jar file like this:
|
||||
|
||||
java -jar CompilePackage.jar <source directory> <output file>
|
||||
|
||||
To recompile the assets.epk file found in /javascript, run:
|
||||
|
||||
java -jar CompilePackage.jar "../lwjgl-rundir/resources" "../javascript/assets.epk"

Again, if you install the bitchfilter plugin, you need to /op yourself with ALL LOWERCASE LETTERS like "/op lax1dude", and then when you want to join as an op you don't type 'LAX1DUDE' you have to join as 'lax1dude' or you will be kicked by the plugin for security
