SMP Entity datawatcher usage

//For _both_ client and server entity file, have this in your constructor, using health integer for example

//18 is the id (the max is 31)
dataWatcher.addObject(18, new Integer(health));


//then simply access and set the variable using 2 functions

//get
dataWatcher.getWatchableObjectInt(18)

//set
dataWatcher.updateObject(18, Integer.valueOf(health));



//and thats it, the rest is magic :D
