How to get 2d3d to always rotate to face player

[Deano3663]

I currently have this:

    ang = LocalPlayer():EyeAngles()

    cam.Start3D2D( Vector(0, 0, 0),Angle(0,ang.y-90,90), 1 )
        surface.SetTextColor( 255, 255, 255, 255 )
        surface.SetTextPos( 0, 0 )
        draw.DrawText("Hello World Test" )
    cam.End3D2D()

and it rotates on the x axis fine however id like it to rotate if the player is below it or above it.
basically the roll axis / z axis ( i think)

Any help is appreciated

function angto(target)

local ply = LocalPlayer()

local vec = (ply:GetPos() - target:GetPos()):GetNormalized()
local ang = vec:Angle()

return ang

end

local lookat = angto(v).y

Hope this helps

I believe this should work.

local ang = LocalPlayer():EyeAngles()
ang:RotateAroundAxis(ang:Forward(),90)
ang:RotateAroundAxis(ang:Right(),90)

Then make it a local function if you have a problem with that...

local function angto(target)

local ply = LocalPlayer()

local vec = (ply:GetPos() - target:GetPos()):GetNormalized()
local ang = vec:Angle()

return ang

end

Count how many functions your calling compared to the method I suggested.

Still new to lua, just thought I had an idea, besides wouldnt your way make the cam3d2d face wherever the player faces, not actually at them unless the player is looking at it?

You win that I guess

You just need replace the control-rotation angle with the angle of the position from a bone of the model (Problem is not every model will have the same set of bones).

I tried this with yaw, but not pitch or roll. Should still work though. I choose this method because it's easy to understand.

local ang = EyeAngles()
for k,v in pairs(ang) do ang[k] = v + 180 end
local dir = ang:Forward()

Then, just use the normal (dir) for the direction of the text.
