not fully implemented yet. this is a solid start. i have to commit before i break something. MojangsonParser: Parses strings in Mojangson format (the JSON variant Minecraft uses for commands) and converts them into NBT Tag objects. PlayerSelector: Implements Minecraft selectors (@p, @a, @r, @e, @s) to filter entities based on criteria. Supported clauses: x,y,z - origin coordinates r,rm - max/min radius (spherical distance) dx,dy,dz - axis-aligned bounding box c - number of entities to return l,lm - player experience level m - game mode (0=S,1=C,2=A,3=Spec) name - exact entity name type - entity type (with ! inversion support) team - team (placeholder, not implemented) rx,rxm,ry,rym - rotation (pitch/yaw) nbt - NBT filter (first level only) some of them not working yet. or have to be fixed, or misses something to implement.
