Patch - Hoverdrive Jammer SENT

[SuperLlama]

Ok, that's all I wanted was a decision.

Just to say though, I do not plan to release this on its own or unofficially, ever. Not because it requires the original, but I think its useless to release something that cannot be 'expected' on most servers. The whole point of it is for people to be able to survive on ALL servers, not just ones with the extra mod installed. If its not going officially to most servers, its not going at all.

You could override the default Jump behaviour without rewriting the whole entity.

local HoverDrive = scripted_ents.GetStored("gmod_wire_hoverdrivecontroller")
local OldJump = HoverDrive.Jump
function HoverDrive:Jump()
  for _, jammer in pairs(HoverdriveJammers) do
    if jammer:InRadius(self) then
      return self:FailJump()
    end
  end
  return OldJump(self)
end

I think it'd be cooler if instead of not jumping it jumped to the edge of the radius though.

function HoverDrive:Jump()
  for _, jammer in pairs(HoverdriveJammers) do
    if jammer:InRadius(self) then
      self.JumpTarget = SphereHitPos(self:GetPos(), self.JumpTarget - self:GetPos(), jammer:GetPos(), jammer:GetRadius())
    end
  end
end

Given that the SphereHitPos is defined something like this

-- http://en.wikipedia.org/wiki/Line%E2%80%93sphere_intersection
function LineSphereIntersect(l, c, r)
    l:Normalize()
    local lc = l:dot(c)
    local det = lc*lc - c:dot(c) + r*r
    if det < 0 then return
    elseif det == 0 then
        return lc
    else
        det = math.sqrt(det)
        return lc + det, lc - det
    end
end

function SphereHitPos(Origin, Direction, SphereCentre, SphereRadius)
    Direction:Normalize()
    local max, min = LineSphereIntersect(Direction, SphereCentre, SphereRadius)
    if min>max then max, min = min, max end
    return Origin + Direction*min
end

[TomyLobo]

that will give you a lua error
something like "comparing a number to nil"

You spelled all the "Dot"s wrong as well

[fishface60]

Serves me right for programming while tired.
If the comparing number to nil is from comparing max and min then it probably won't have that error very often since that's if the line just touches the sphere. It could be easily fixed by either checking that both exist in SphereHitPos, or making LineSphereIntersect return lc twice.
