How to run a trace in the direction an entity is traveling.

[ResidualGrub]

I am trying to run a trace in the direction an entity is travailing and I am having a difficult time getting it working.
This is how I am trying to do it

local pos = ent:GetPos()
util.QuickTrace( pos, (pos + ent:GetVelocity():GetNormalized()) * 300 , ent )

I thought it would work the same way as running a trace based off of GetForward() but it is always returning an inconstant direction that does not coincide with the ents velocity. Does anyone have a way of doing this?

It looks like your math is wrong. You should be multiplying just the normalized velocity by 300 but you're multiplying pos + velocity * 300.

Thought so too but it provides the same result.

hook.Add("PostDrawTranslucentRenderables", "", function()
    local ply = LocalPlayer()
    local pos = ply:GetPos()
    local vel = ply:GetVelocity()
    local vec = vel:Angle():Forward()

    render.DrawLine(pos, pos + vec * 300, Color(255, 0, 0))
end)
