GetPhysicsObject on client

[Atomsk.]

Is there anyway to use [url]http://wiki.garrysmod.com/page/Entity/GetPhysicsObject[/url] on an entity clientside?

[Dear_Matt]

Well you could use PhysicsInit on the client object, usually they dont have that by default because the server is managing all that well except clientside ragdolls.

Also if you initialize the physics on the client u'll be noticing that they arent synchronized with the server physics just like that, you would need to manually set its position every frame.

I used to mess with this stuff a while ago.

[lua]
ClientsidePhysics = ClientsidePhysics or {}
ClientsidePhysics.Active = ClientsidePhysics.Active or {}
ClientsidePhysics.Disabled = ClientsidePhysics.Disabled or {}
ClientsidePhysics.Whitelist = {}
ClientsidePhysics.Whitelist["prop_physics"] = 1

function ClientsidePhysics:Disable(ent)

if ent.ClientsidePhysicsTracking then

local phys = ent:GetPhysicsObject()
if IsValid(phys) then

--print("Disabled physics: ", ent)
ent:PhysicsDestroy()

self.Disabled[ent] = true

end

end

end

function ClientsidePhysics:Enable(ent)

if self.Disabled[ent] ~= nil then

--print("Enabled Physics: ", ent)
ent:PhysicsInit(SOLID_VPHYSICS)

self.Disabled[ent] = nil

end

end

local ENT = FindMetaTable("Entity")

if ENT.PhysicsInitOverride == nil then
ENT.PhysicsInitOverride = ENT.PhysicsInit
end

if ENT.PhysicsDestroyOverride == nil then
ENT.PhysicsDestroyOverride = ENT.PhysicsDestroy
end

function ENT:PhysicsInit(flags)

ENT.PhysicsInitOverride(self, flags)

local phys = self:GetPhysicsObject()
if IsValid(phys) then

phys:EnableMotion(false)
self.ClientsidePhysicsTracking = true

ClientsidePhysics.Active[self] = true

end

end

function ENT:PhysicsDestroy()

ENT.PhysicsDestroyOverride(self)

self.ClientsidePhysicsTracking = false

ClientsidePhysics.Active[self] = nil

end

function ENT:PhysicsTrackingActive()

if self.ClientsidePhysicsTracking ~= nil then
return self.ClientsidePhysicsTracking
end

return false

end

hook.Add("Think", "ClientsidePhysics", function()

for v,_ in pairs(ClientsidePhysics.Active) do

if v.ClientsidePhysicsTracking then

local phys = v:GetPhysicsObject()
if IsValid(phys) and v:IsDormant() == false then

phys:EnableMotion(false)
phys:SetPos(v:GetPos())
phys:SetAngles(v:GetAngles())
phys:SetVelocity(v:GetVelocity())

end

end

end

end)

hook.Add("EntityRemoved", "ClientsidePhysicsRemove", function(ent)

ClientsidePhysics.Active[ent] = nil
ClientsidePhysics.Disabled[ent] = nil

end)

hook.Add("NetworkEntityCreated", "ClientsidePhysics", function(ent)

if ClientsidePhysics.Whitelist[ent:GetClass()] ~= nil then

local phys = ent:GetPhysicsObject()
if not IsValid(phys) then

ent:PhysicsInit(SOLID_VPHYSICS)

end

end

end)

hook.Add("PhysgunPickup", "ClientsidePhysicsPickup", function(ply, ent)
ClientsidePhysics:Disable(ent)
end)

hook.Add("PhysgunDrop", "ClientsidePhysicsDrop", function(ply, ent)
ClientsidePhysics:Enable(ent)
end)

-- Those are not shared at the moment, should we setup some usermessage/net message?
-- The gravity gun takes away the clientside physics, so we have to deal with this.
hook.Add("GravGunOnPickedUp", "ClientsidePhysicsPickup", function(ply, ent)
ClientsidePhysics:Disable(ent)
end)

hook.Add("GravGunOnDropped", "ClientsidePhysicsDrop", function(ply, ent)
ClientsidePhysics:Enable(ent)
end)
[/lua]

There is an issue with the Gravity gun, it will kill the physics on the client haven't worked that out yet so ignore the useless hooks.

EDIT: One might ask what this is all about, long story short: This would allow clientside ragdolls to actually collide with your shitty contraptions.
