103 Misc parameter. Initialized to 0.
104 - For light_propagates() blocks, this is light intensity,
105 stored logarithmically from 0 to LIGHT_MAX.
106 Sunlight is LIGHT_SUN, which is LIGHT_MAX+1.
107 - Contains 2 values, day- and night lighting. Each takes 4 bits.
108 - Uhh... well, most blocks have light or nothing in here.
113 The second parameter. Initialized to 0.
114 E.g. direction for torches and flowing water.
