Now it is possible to make mods to the hydro mod.

The water adds readable variable named WaterHeight and if you want your actor to be unaffected by the water you just make his sharpness 2 (for some reason 0.9994253 didn't work).

Heres some basic codes you can play around with and get a idea how it works.


Code:
function Create(self)
end

function Destroy(self)
end

function Update(self)
  local water = false
  if WaterHeight ~= nil then
    water = true
  end
  if water == true and self.Pos.Y + self.Vel.Y >  WaterHeight then
    self.Vel = self.Vel * 0.9
    self.AngularVel = self.AngularVel * 0.9
  end
end

Place this on a actor with sharpness = 2 and you've got a dude that walks on the bottom.


Code:
function Create(self)
end

function Destroy(self)
end

function Update(self)
  local water = false
  if WaterHeight ~= nil then
    water = true
  end
  if water == true and self.Pos.Y + self.Vel.Y >  WaterHeight then
    self.Vel = self.Vel * 0.9 - 1
    self.AngularVel = self.AngularVel * 0.9
    self.AngularVel = self.AngularVel - ((self.RotAngle + self.AngularVel) * 0.015)
    self.RotAngle = self.RotAngle * 0.99
  end
end

This is a code you can attach on a crab (with sharpness = 2) to make it float like a boat.

These scripts won't make your mod need hydro to run.

you could add some simple checks like
Code:
string.find(actor.Material,"metal") ~= nil

or
Code:
string.find(actor.Material,"flesh") ~= nil


Even if modders are using custom materials, their material names just might make some sense.

Actually the hydro mod is 100% dynamic when it comes to non-actor physics. This was made because numgun said it would be cool if other modders could make boats, submarines... to the mod without needing to make it a part of the mod. Other than that i thought it would be cool that my new hovercraft could skim over the water like it was earth.
