What would be the best way to create a 'kick animation'

[Ricky Servietsky]

Hi,
I want to create a swep to kick doors open and i'm wondering what is the best way to create a new animation, for exemple in the m9k package you have weapon fist, is that a custom animation ? How did they manage to do such an anim ? I looked into the 'Player animation' wiki and its written :
'it is technically impossible at the moment to *add* onto the existing animations, sadly' What does it means ?

I was thinking of make the player invisible and spawn in a ragdoll then maybe moove the ragdoll instead of creating an animation ? I'm clueless about what should i do...
I'm willing to learn but i don't want to go on a dirty solution.
If you can just tell me what kind of process i should follow or give me a link it would be appreciated...
PS : I want to use HL2 player models, is that a problem ?

Thanks in advance for any lead !

You can use JetBoom's animation API to create your own animations in Lua. Alternatively, you can use a BuildBonePositions callback (see Entity:AddCallback) to manually move the bones in the way you want.

Like code_gs suggested, Jet's AnimationsAPI is definitely the easiest way to go about it without having to make separate models. And his API uses ManipulateBonePosition internally.

I personally wouldn't recommend using it since it can conflict with other addons. Using a BuildBonePositions callback will maintain that support since bone manipulations are applied afterwards.

i'm a bit confused on where i should call the BuildBonePosition i only see 3 callback ! Should i add it in a "BuildBonePositions" hook? It seems to be triggered every damn frame !

[c👌de_g🎷]

Example on how to add a callback is on the page - just substitute the first argument with "BuildBonePositions". It's called every frame since player bone positions are updated that often, and the bone positions for the animations should be, as well.

I did add a callback, but I'm using it in a swep, only way to add it is in the 'initialize' function, but if SWEP:Initialize() fire multiple time it will add multiple callback no ? Should I check if the callback is instantied at each SWEP:Init ?

[c👌de_g🎷]

You can store the callbackid returned by AddCallback on the weapon, then before adding a new callback, check if there is a callbackid available. Ex.
function SWEP:AddPlayerCallback()
-- Callback doesn't exist yet
if (self.m_iBoneCallback == nil) then
local pOwner = self:GetOwner()

if (pOwner:IsValid()) then
self.m_iBoneCallback = pOwner:AddCallback("BuildBonePositions", funchere)
end
end
end
Whenever you remove the callback, set m_iBoneCallback to nil. Alternatively, it might be better to store the variable on the player entity instead of the weapon.

function SWEP:PrimaryAttack()
  if not IsFirstTimePredicted() then return end
  self:Initialize()

end

function SWEP:SecondaryAttack()
  if not IsFirstTimePredicted() then return end
  self:RemoveCallbackZ('bbpcbid')
end

function SWEP:RemoveCallbackZ( varIndex )

  if self.Owner:GetTable()[varIndex] then
    self.Owner:RemoveCallback("BuildBonePositions", self.Owner:GetTable()[varIndex])
    self.Owner:SetVar(varIndex, nil )
  end

end

function SWEP:DrawWorldModel()
return false
end

function SWEP:Deploy()
self.Owner:DrawViewModel(false)
end

function SWEP:Initialize()
  self:SetHoldType(self.HoldType)

    if not self.Owner:GetTable()['bbpcbid'] then
      print("no bbpcbid in player table, adding one")
      local callbackId = self.Owner:AddCallback("BuildBonePositions", function(entTarget)

         local head = entTarget:LookupBone("ValveBiped.Bip01_Head1")
         local headPos,headAng = entTarget:GetBonePosition(head)

         entTarget:SetBonePosition(head, headPos + Vector(0,0,10), headAng)

      end )
      self.Owner:SetVar("bbpcbid", callbackId )
    end
    --self.Owner:RemoveCallback( "BuildBonePositions", number callbackid )
end

Ok so my callback is giving my player a 'long neck', when i right click it's supposed to remove the callback (it did remove it) but it's only working clientside, player still see me with a long neck even if i remove the callback and when i look in the camera it works fine for me... I did make the update to 'add' RemoveCallback serverside (i don't have any error anymore) so i don't understand wtf is happening
