How do I rotate an entire model?

So I’m trying make sword model rotate, I’ve set primarypart and cframe but this happens:

But this is what I want to happen:

Its broken and I don’t know why, here is the script

I tried rotating each part at a time but came out with this:

https://gyazo.com/d6c05e099eb84e95e4fff01b92c752d9

Here is the script,

script.Parent.PrimaryPart = script.Parent.H

script.Parent:SetPrimaryPartCFrame(script.Parent.H.CFrame)

while wait(0.081) do

for i,v in pairs(script.Parent:GetChildren()) do

if v:IsA("Part") or v:IsA("MeshPart") and v.Name == "H" then

v.Orientation = v.Orientation + Vector3.new(0,1,0)

print("rot")

end

end

end

How can I make a ViewPort with a rotating image?

Here’s a tip:

Instead of using Orientation try using CFrame.Angles when using SetPrimaryPartCFrame()

If the reply above does not work ( which it probably will, however I am away from my laptop ), try Welding all the parts to your primary part and rotating the PrimaryPart from there.

#4

I already tried that, but the result was that same.

#5

I see. My apologies.

It’s possible you could try tweening the model. Here’s a good tutorial on it:
Introduction to Tweening Models

#6

I’m not very great with CFrame.Angles but here is what I got,

local angleOffset = (script.Parent.H.CFrame * CFrame.Angles(0,math.rad(script.Parent.H.Orientation.X + 2),0))
   script.Parent:SetPrimaryPartCFrame(script.Parent.H.CFrame * angleOffset )

It glitches all over the maps constantly teleporting

#7

Take that part out on angleOffset since it will multiply the CFrame by itself, which causes it go haywire.

#8

I think the people here don’t know what they’re talking about. Your issue is likely in the if statement; you can just check if something is a BasePart instead, and using or and and in the same line without parentheses will cause you to mess something up.

#9

Your fix is probably what @DevHumor suggested

Something like:

speed=math.rad(1)*40
while wait(.081) do
    currentCFrame=script.Parent:GetPrimaryPartCFrame()
    script.Parent:SetPrimaryPartCFrame(currentCFrame * CFrame.Angles(0, speed, 0))
end

Where you went wrong earlier was setting the angle offset; if you want a constant velocity rotation then the angle offset should be constant. Before you calculated the angle offset as a full CFrame (with position); which made it go haywire when you multiplied that CFrame position and rotation with the original.

Tysm, one problem though. For the most part it works but once it starts it randomly stops

I removed the script.Parent.H.CFrame part

#11

Hmn, this is something I have not seen before.

Mind if I check out the edited script to see what I can find? It does seem to print it out, but somehow the CFrame didn’t get through.

#12

Yes of course (Sorry for the late reply, I went for a run outside)

script.Parent.PrimaryPart = script.Parent.H
while wait(0.02) do
	for i,v in pairs(script.Parent:GetChildren()) do
	if v:IsA("Part") or v:IsA("MeshPart") and v.Name == "H" then
			local angleOffset = ( CFrame.Angles(math.rad(script.Parent.H.Orientation.X + 0.2),0,math.rad(0.0001)))
   script.Parent:SetPrimaryPartCFrame(script.Parent.H.CFrame * angleOffset )

		print("rot")
	end
end
end
	end
end
end

I really do not suggest using a very small number because it will make it look like it’s moving very slow despite having a loop run every 0.02 seconds.

Bump it up to 1 or higher if you can.

As for the stopping thing, I couldn’t seem to find any issues that’s causing it. :thinking:

#14

Its okay, I have figured out the issue. Its due to the ‘H’ moving to a different orientation while not doing so at the same time. I bumped 0.2 to 10 and it works like a charm, its not changing the orientation 100% of the way but instead making it seem like it is. Basically what I’m saying is that it sets it to a position instead of always adding a position.

https://gyazo.com/af5a549c9058f7376afe1eeb3e9186b9

script.Parent.PrimaryPart = script.Parent.H
while wait(0.02) do
	for i,v in pairs(script.Parent:GetChildren()) do
	if v:IsA("Part") or v:IsA("MeshPart") and v.Name == "H" then
			local angleOffset = ( CFrame.Angles(math.rad(script.Parent.H.Orientation.X + 10),0,0))
   script.Parent:SetPrimaryPartCFrame(script.Parent.H.CFrame * angleOffset )


		print("rot")
	end
end
end

I really appreciate your help, thank you very much :smiley:

You can see the orientation going up then resetting back to the bottom, I tried cropping the video but gyazo sadly can’t do that.
