Help with ragdoll swep

[ferrous]

I want to make a swep that fires ragdolls, but I am a complete beginner at Lua.

Knowing nought about Lua I decided to use this fruit launcher I found on gmod.org as a base. Is it as simple as changing the model to a ragdoll?

if (SERVER) then 
AddCSLuaFile ("shared.lua"); 
SWEP.Weight = 5; 
SWEP.AutoSwitchTo = false; 
SWEP.AutoSwitchFrom = false; 
end 
if (CLIENT) then
SWEP.PrintName = "Fruit Launcher"; 
SWEP.Slot = 3; 
SWEP.SlotPos = 1; 
SWEP.DrawAmmo = false; 
SWEP.DrawCrosshair = false; 
end 
SWEP.Author = "Waffle"; 
SWEP.Contact = ""; 
SWEP.Purpose = ""; 
SWEP.Instructions = ""; 
SWEP.Category = "Prop Launchers" 
SWEP.Spawnable = true; 
SWEP.AdminSpawnable = true; 
SWEP.ViewModel = "models/weapons/v_rpg.mdl"; 
SWEP.WorldModel = "models/weapons/w_rocket_launcher.mdl"; 
SWEP.Primary.ClipSize = -1; 
SWEP.Primary.DefaultClip = -1; 
SWEP.Primary.Automatic = false; 
SWEP.Primary.Ammo = "none"; 
SWEP.Secondary.ClipSize = -1; 
SWEP.Secondary.DefaultClip = -1; 
SWEP.Secondary.Automatic = false; 
SWEP.Secondary.Ammo = "none"; 
local ShootSound = Sound ("Metal.SawbladeStick"); 
function SWEP:Reload() 
end 
function SWEP:Think() 
end 
function SWEP:throw_attack (model_file) 
local tr = self.Owner:GetEyeTrace(); 
self.Weapon:EmitSound (ShootSound); 
self.BaseClass.ShootEffects (self); 
if (!SERVER) then return end; 
local ent = ents.Create ("prop_physics"); 
ent:SetModel (model_file); 
ent:SetPos (self.Owner:EyePos() + (self.Owner:GetAimVector() * 16)); 
ent:SetAngles (self.Owner:EyeAngles()); 
ent:Spawn(); 
local phys = ent:GetPhysicsObject(); 
local shot_length = tr.HitPos:Length(); 
phys:ApplyForceCenter (self.Owner:GetAimVector():GetNormalized() * math.pow(shot_length, 3)); 
cleanup.Add (self.Owner, "props", ent); 
undo.Create ("Launched fruit"); 
undo.AddEntity (ent); 
undo.SetPlayer (self.Owner); 
undo.Finish(); 
end
function SWEP:PrimaryAttack() 
self:throw_attack ("models/props/cs_italy/orange.mdl"); 
end 
function SWEP:SecondaryAttack() 
self:throw_attack ("models/prop

Create a prop_ragdoll rather than a prop_physics. Aside from that, yes.

[ferrous]

Thanks.

How can I increase the velocity at which the ragdoll flies out of the swep?

phys:ApplyForceCenter (self.Owner:GetAimVector():GetNormalized() * math.pow(shot_length, 3));

Does that have anything to do with it?

[QUOTE=ferrus;16780203]nudgings[/QUOTE]

is that something like a bump?

[stinkfire]

lol. It is when his thing is to far down no one is going to read it. Therefore he nudges it up.

I think so yes.
(to his question)

[ferrous]

Still can't get it to fire with more force. Basically what I want is for it to fire at such high velocity that the ragdoll has a seizure.

:D

[ferrous]

anyone?

[JSharpe]

It's pretty straight forward.

do a generic for looping through all the bones of the created ragdoll and apply a force to each one. Make sure you start iterating at 0, not 1 too.

Slightly related code:

[lua]
for i=0, target:GetPhysicsObjectCount( ) -1 do

local physBone = target:GetPhysicsObjectNum( i )
if (physBone:IsValid()) then

--Apply the force here to physBone
end

end

[/lua]

Any chance you could edit this for me? I really don't know how to do it.

AddCSLuaFile ("shared.lua");
SWEP.Weight = 5;
SWEP.AutoSwitchTo = false;
SWEP.AutoSwitchFrom = false;

function SWEP:PrimaryAttack()
self:throw_attack ("models/player/zombiefast.mdl");
end
function SWEP:SecondaryAttack()
self:throw_attack ("models/player/police.mdl");
end
[/lua]

As I said - complete beginner at Lua.

Of course. I reformatted your code so it's also easier to read, it will still run if it's formatted differently, it should be a habbit you get into.

Untested like. But I added a few comments in there so you understand what's going on and what you might want to to (the "TODO")

[lua]
function SWEP:throw_attack (model_file)

local tr = self.Owner:GetEyeTrace();

self.Weapon:EmitSound (ShootSound);
self.BaseClass.ShootEffects (self);

if (!SERVER) then return end;

local ent = ents.Create ("prop_ragdoll");
ent:SetModel (model_file);
ent:SetPos (self.Owner:EyePos() + (self.Owner:GetAimVector() * 16));
ent:SetAngles (self.Owner:EyeAngles());
ent:Spawn();

--local phys = ent:GetPhysicsObject();
local shot_length = tr.HitPos:Length();

--TODO: Try apply force to a few specific parts of the body. As this code will 'throw' the
-- ragdoll in the same pose as it was created IIRC.
-- Forgot how weights of the bone interact.
for i=0, ent:GetPhysicsObjectCount( ) -1 do --Iterate from 0, as there is a bone numbered 0.

local physBone = ent:GetPhysicsObjectNum( i ) --Select/Declare that bones physics object.
if (physBone:IsValid()) then --Just in case.

--Apply the force here to physBone
physBone:ApplyForceCenter( self.Owner:GetAimVector():GetNormalized() * math.pow( shot_length, 3 ) );
end

end

cleanup.Add (self.Owner, "props", ent);
undo.Create ("Launched Ragdoll");
undo.AddEntity (ent);
undo.SetPlayer (self.Owner);
undo.Finish();
end
[/lua]

[ferrous]

Thanks! So is the 'shot_length' the force applied? i.e changing it to 4 from 3 = more force?

[Jam]

I like that math function name "Math.pow"

Sounds like its from a Jappaneese Kung-Fu movie.
