Entity:PhysicsInitConvex
Description
Initializes the physics mesh of the entity with a convex mesh defined by a table of points. The resulting mesh is the of all the input points. If successful, the previous physics object will be removed.
This is the standard way of creating moving physics objects with a custom convex shape. For more complex, concave shapes, see Entity:PhysicsInitMultiConvex.
Clientside physics objects are broken and do not move properly in some cases. Physics objects should only created on the server or you will experience incorrect physgun beam position, prediction issues, and other unexpected behavior.
Issue Tracker: 5060
You can use the following workaround for movement, though clientside collisions will still be broken.
function ENT:Think()
if ( CLIENT ) then
local physobj = self:GetPhysicsObject()
if ( IsValid( physobj ) ) then
physobj:SetPos( self:GetPos() )
physobj:SetAngles( self:GetAngles() )
end
end
end

Arguments
1 table points
A table of eight Vectors, in local coordinates, to be used in the computation of the convex mesh. Order does not matter.
2 string surfaceprop = "default"
Physical material from surfaceproperties.txt or added with physenv.AddSurfaceData.
Returns
Example
Creates a "box" physics mesh for the entity.
function ENT:Initialize()
if ( CLIENT ) then return end -- We only want to run this code serverside
local x0 = -20 -- Define the min corner of the box
local y0 = -10
local z0 = -5
local x1 = 20 -- Define the max corner of the box
local y1 = 10
local z1 = 5
self:PhysicsInitConvex( {
Vector( x0, y0, z0 ),
Vector( x0, y0, z1 ),
Vector( x0, y1, z0 ),
Vector( x0, y1, z1 ),
Vector( x1, y0, z0 ),
Vector( x1, y0, z1 ),
Vector( x1, y1, z0 ),
Vector( x1, y1, z1 )
} )
-- Set up solidity and movetype
self:SetMoveType( MOVETYPE_VPHYSICS )
self:SetSolid( SOLID_VPHYSICS )
-- Enable custom collisions on the entity
self:EnableCustomCollisions( true )
