I’ve been working with viewport frames recently, and it has been a little tough. For the past few days, I’ve been having trouble with positioning models with a primary part and gear.
I have a model of three buttons and this is what I have so far.
I want to orient it horizontally and make the top of the buttons slightly more tilted towards the camera. But, after trying to do that I get this.
I’m not good with CFrames, so I might of done something wrong.
updateButtonPreview
local function updateButtonPreview(item)
itemPreview:ClearAllChildren()
local itemObject = item["Object"]:Clone()
itemObject.Parent = itemPreview
itemObject:SetPrimaryPartCFrame(CFrame.new(viewportPoint)) -- viewport point is just Vector3.new(0,0,0)
itemObject:SetPrimaryPartCFrame(itemObject.PrimaryPart.CFrame * CFrame.Angles(45,90,0))
updateViewportCamera(itemObject,0.25)
end
I have other problems with previewing gear. The camera I apply doesn’t really fit all the gears. For example, I have a burger too close to the camera, and then a cake that is facing the wrong way. How would I account for all the different rotations and distances of each gear?
Here is the code for the gear preview and the viewport camera.
updateGearPreview
local function updateGearPreview(item)
itemPreview:ClearAllChildren()
local itemObject = item["Object"]:Clone()
local model = Instance.new("Model")
local handle = itemObject:FindFirstChild("Handle")
handle.Parent = model
model.PrimaryPart = handle
itemObject = model
itemObject.Parent = itemPreview
itemObject:SetPrimaryPartCFrame(CFrame.new(viewportPoint))
updateViewportCamera(itemObject,5)
end
updateViewportCamera
local function updateViewportCamera(item,distance)
local cframe, size = item:GetBoundingBox()
local max = math.max(size.X, size.Y, size.Z)
local distance = (max/math.tan(math.rad(viewportCamera.FieldOfView))) * distance
local currentDistance = (max/2) * distance
viewportCamera.CFrame = CFrame.new(viewportPoint + Vector3.new(0,0,currentDistance), viewportPoint)
end
Any help or feedback would be appreciated!
