* * Add BuildActionIntention crap * * Set Client and World projects to use MP compilation * asd * * Use the new BuildActionIntention to break and place blocks. * * Reverse engineer the IArea system. * * Copy break logic from survival into creative conditionally * * Reverse IBuildInput and MouseHandler * Replace the new relative paths in the client project with $(MC_ROOT) again * * Reverse Multitouch, MouseDevice * * Reverse a bunch of auxiliary classes for input. * * Use CustomInputHolder instead of holding inputs manually. * * Reverse a whole BUNCH of things! * * Add feedback textures to the gitignore. * * D-pad now renders! Also loads of other work. * * More Stuff * * Finish touch control bug fixing. * * Finalize work. * * One last thing.. * * Add a "cramped" mode to the options screen and start menu. * * Oh, forgot to do something
