# action plan for final product:
|
|
# 1) Get a list of mod jars from a directory
|
|
# 2) Install appropriate version of minecraft if it is not already installed
|
|
# 3) Install appropriate version of minecraft forge if it is not already installed
|
|
# 4) Launch empty version of minecraft forge to generate boilerplate file structure
|
|
# 5) Exit the process after it launches successfully
|
|
# 6) For each Jar:
|
|
# a) Copy jar to directory
|
|
# b) Attempt to launch the game
|
|
# c) Record whether or not the game successfully launched/built/etc
|
|
# d) If the game failed to launch, mark the jar as disabled
|
|
# e) Continue to next jar
