Mining drill and laser EU requirement based on node groups

[S-S-X]

https://minetest.gitlab.io/minetest/groups/

Just like other tools speed is affected by node groups make drill and laser use energy based on groups. Harder nodes should use more energy while softer ones use less.

Please do understand this, otherwise you cannot use the system to it's full potential. -- celeron55

The drill code is pretty easy to retrofit i think: https://github.com/mt-mods/technic/blob/7cdb21ae56a3ea74784e4fa3c6fa45a8b73c8772/technic/tools/mining_drill.lua#L49-L63

Not sure about the laser, most "digging" logic seems to be in here: https://github.com/mt-mods/technic/blob/7cdb21ae56a3ea74784e4fa3c6fa45a8b73c8772/technic/tools/mining_lasers.lua#L36-L50

Is there even a helper function in the api to determine/evaluate all those groups?

There is thing that could be used:

• minetest.get_dig_params(groups, tool_capabilities): Simulates a tool that digs a node. Returns a table with the following fields:
  • diggable: true if node can be dug, false otherwise.
  • time: Time it would take to dig the node.
  • wear: How much wear would be added to the tool. time and wear are meaningless if node's not diggable Parameters:
  • groups: Table of the node groups of the node that would be dug
  • tool_capabilities: Tool capabilities table of the tool

Then do some more or less clever math with time and wear to get factor for base energy usage.
