What is DummyCore?
DummyCore is an API used by DummyThinking team to make mods. It contains some usefull functions, that make it easier for us to mod.
Different functions that DummyCore provides:
1)Easier mod/cfg registration
2)Automatic creation of creative tabs
4)A new way to work with data(save it to string and parse later)
5)World/player save handlers(allows to save your data)
6)Lots of usefull functions in MiscUtils
8)Custom main menu support
9)ASM feature to remove interfaces of your .class files(do not know what that is? google it!)
You can use DummyCore as an API for your mods if you like to - the API is documented, so you can understand everything there is(at least I hope so)
Installation guide - universal
1)If you do not have minecraftforge installed, install it. It is really simple with their new installer.
2)Download the mod itself.
3)Put the downloaded .zip into your mods folder
4)Launch the game to see if everything works correctly.
