Physics Properties

Physics Properties

Weight, friction and floating come from Sable's physics_block_properties datapack files. Sable Trees ships these, all with priority 1100:

Selector	sable:mass	sable:friction	sable:volume
#minecraft:logs	3.0	1.5	4.0
sabletrees:notched_log	3.0	1.5	4.0
sabletrees:rotten_log	1.5	1.5	3.0
#minecraft:leaves	0.2
#sabletrees:tree_foliage	0.2

Sable applies these files in priority order, and the highest priority wins, property by property. Its default priority is 1000, so to override these values use a priority above 1100.

{
  "selector": "#minecraft:logs",
  "priority": 1200,
  "properties": {
    "sable:mass": 1.5
  }
}

What changing the weight does

Part of the mod	Affected?
Tipping toward the notch	No: the push scales with mass
TNT launching trees	No: the impulse scales with mass
Snapping branches and fall damage	No: they use fixed values of their own (log 3, rotten log 1.5, leaf 0.2)
Domino effect	Yes: lighter trees knock down fewer neighbors
Floating	Yes: a log that is too heavy for its volume sinks

Handles and the Log Hook are also tuned to these weights.
