Model Frames - Resizing Units and Aligning them to Bottom

[RobolaVirus]

I'm fighting through a bit of frustrating behaviour that I hope somebody has some tips on.

I have two PlayerModels displayed on screen. Default behaviour is for the unit to fill the size of the frame it sits inside, which makes sense for the most part. But I'm looking to retain some sense of scale when displaying the two models, so goblins don't appear as big as Tauren.

Anybody have any ideas on how I can display two models on the screen and have their size appear somewhat relative to how they appear in game? The models will change, so I'll need to dynamically recalculate it based on the unit.

An additional issue I've noticed is the model is always centered inside the frame, so if I just resize the frame, the 'feet' of the models don't line up anymore. I'd like to make it look almost like they're standing on a plane.

Thoughts?!?!

Code for your PlayerModel frames? (creation, anchoring, etc.)

Basically:

local DialogueMode = CreateFrame("Frame", "DialogueFrame")
DialogueMode:SetScale(UIParent:GetScale())
DialogueMode:SetAllPoints(UIParent)

DialogueMode.Backdrop = CreateFrame("Frame", "Backdrop", DialogueMode)
DialogueMode.Backdrop:SetFrameLevel(90)
DialogueMode.Backdrop:SetPoint("BOTTOM", DialogueMode, "BOTTOM", 0, 0)
DialogueMode.Backdrop:SetWidth(DialogueMode:GetWidth())
DialogueMode.Backdrop:SetHeight(DialogueMode:GetHeight())
DialogueMode.Backdrop.texture = DialogueMode.Backdrop:CreateTexture(nil, "BACKGROUND")
DialogueMode.Backdrop.texture:SetAllPoints(true)
DialogueMode.Backdrop.texture:SetTexture(0, 0, 0, .9)

--Create and Load the Player Frame
DialogueMode.Backdrop.ThePlayerModel = CreateFrame("PlayerModel", "ThePlayer", DialogueMode.Backdrop)
DialogueMode.Backdrop.ThePlayerModel:SetFrameLevel(99)
DialogueMode.Backdrop.ThePlayerModel:SetPoint("BOTTOM", DialogueMode.Backdrop, "BOTTOM", -(DialogueMode.Backdrop:GetWidth()/4), 0) --(DialogueMode:GetWidth()/4)
DialogueMode.Backdrop.ThePlayerModel:SetSize(600, 600)
DialogueMode.Backdrop.ThePlayerModel:SetCamDistanceScale(1.25)
DialogueMode.Backdrop.ThePlayerModel:SetFacing(.8)
DialogueMode.Backdrop.ThePlayerModel:SetUnit("player")

--Create the Target Frame
DialogueMode.Backdrop.TheTargetModel = CreateFrame("PlayerModel", "TheTarget", DialogueMode.Backdrop)
DialogueMode.Backdrop.TheTargetModel:SetFrameLevel(99)
DialogueMode.Backdrop.TheTargetModel:SetPoint("BOTTOM", DialogueMode.Backdrop, "BOTTOM", DialogueMode.Backdrop:GetWidth()/4, 0)
DialogueMode.Backdrop.TheTargetModel:SetSize(600, 600)
DialogueMode.Backdrop.TheTargetModel:SetCamDistanceScale(1)
DialogueMode.Backdrop.TheTargetModel:SetFacing(6)
DialogueMode.Backdrop.TheTargetModel:SetUnit("npc")

You can always reset a model to it's base camera position and base camera target position like this:

function model:GetBaseCameraTarget()
    local modelfile = self:GetModel()
    if modelfile and modelfile ~= "" then
        local tempmodel = CreateFrame("PlayerModel", nil, UIParent)
        tempmodel:SetModel(modelfile)
        tempmodel:SetCustomCamera(1)
        local x, y, z = tempmodel:GetCameraTarget()
        tempmodel:ClearModel()
        return x, y, z
    end
end
 
function model:SetOrientation(distance, yaw, pitch)
    if self:HasCustomCamera() then
        --self.distance, self.yaw, self.pitch = distance, yaw, pitch
        local x = distance * math.cos(yaw) * math.cos(pitch)
        local y = distance * math.sin(- yaw) * math.cos(pitch)
        local z = (distance * math.sin(- pitch))
        self:SetCameraPosition(x, y, z)
    end
end
 
function model:Reset()
    local modelfile = self:GetModel()
    self:ClearModel()
    self:SetModel(modelfile)
    -- With model id
    --self:SetDisplayInfo(modelid)
    self:SetRotation(0)
    self:SetPosition(0, 0, 0)
    self:RefreshCamera()
    self:SetCustomCamera(1)
    if self:HasCustomCamera() then
        local x, y, z = self:GetCameraPosition()
        local tx, ty, tz = self:GetCameraTarget()
        -- Here you can use tx instead of 0
        self:SetCameraTarget(0, ty, tz)
        self:SetOrientation(math.sqrt(x * x + y * y + z * z), - math.atan(y / x), - math.atan(z / x))
    end
end

That great! I'll have a look. Much appreciated.
