set a models scale via axis using a Vector / EnableMatrix?

[gkgelijah]

Would like a code that will multiply or lengthen the object by its y axis. Any help is appreciated, thanks in advanced

clientside, affects the visuals but not the physics:

local scale = Vector(1,2,1)
local matrix = Matrix()
matrix:Scale(scale)
someEntity:EnableMatrix("RenderMultiply",matrix)

to scale the physics serverside, this will do it for you but on EVERY axis only:

to scale physics serverside to specific axis manipulation:

(but you have to have a boring box shape for the physics, and you have to figure out what the mins/maxs are yourself or via code)

((which means to first get the original mins,maxs of the OBB and to then scale the y component the same way you are in clientside visuals, and then apply all of these as the new physicsinitbox))

function crabheadAttachment( Player )
	local model = ents.Create("prop_dynamic")
	local scale = Vector(1, 2, 1)
	local matrix = Matrix()
	matrix:Scale(scale)
	model:EnableMatrix("RenderMultiply", matrix)
	model:SetModel("models/props_2fort/lunchbag.mdl")
	model:SetModelScale(Vector(1, 2, 1), 0)
	model:SetPos(Player:GetPos() + Vector(-5, -5, 65))
	model:SetAngles(Player:GetAngles() + Angle(0, 0, 0))
	Player:DeleteOnRemove(model)
	model:SetParent(Player)
	model:Spawn()
	model:Fire("setparentattachmentmaintainoffset", "Bip01_Head1", 0.01)
end
hook.Add("PlayerSpawn", "attachtobone", crabheadAttachment)

Would it work like this? If not can you help fix which line of code is incorrect.

enablematrix is clientside, as i said

running it on client+server or just the server will cause an error

it's only for the visuals

[gkgelijah]

How would I go about using this on my shared file? if CLIENT then and etc?

[bitches]

a shared file isn't automatically going to run a function on the client and the server both

it merely means the function of yours will be defined on both ends, not that running crabheadAttachment() serverside will automatically do it clientside

I've created two separate files, sv_attachment_system and cl_attachment_system, i've put the matrix code into the cl file and the spawnable item code into the SV but it doesn't seem to do anything.
sv_attachment_system

function crabheadAttachment( Player )
	if !Player:Alive() then return end
	local model = ents.Create("prop_dynamic")
	model:SetModel("models/props_2fort/lunchbag.mdl")
	model:SetPos(Player:GetPos() + Vector(-5, -5, 65))
	model:SetAngles(Player:GetAngles() + Angle(0, 0, 0))
	Player:DeleteOnRemove(model)
	model:SetParent(Player)
	model:Spawn()
	model:Fire("setparentattachmentmaintainoffset", "eyes", 0.01)
end
hook.Add("PlayerInitialSpawn", "attachtobone", crabheadAttachment)

cl_attachment_system

local Entity = FindMetaTable("Entity")
if !Entity then return end

function Entity:SetModelScale(scale)
	local mat = Matrix()
	mat:Scale(scale)
	self:EnableMatrix("RenderMultiply", mat)
end

function clCrabHead()
	local model = ents.FindByClass("prop_dynamic")
	model:SetModelScale(Vector(1, 2, 1))
end
