Character goes insane after changing the position of the HumanoidRootPart

[7z99 (cody)]

I don’t think you even have to use :SetPrimaryPartCFrame as the joints make it stay consistent when modifying the CFrame. For some reason, this doesn’t work when setting the position and gives odd behaviour.

Position:

workspace['7z99'].HumanoidRootPart.Position = Vector3.new(0,20,0)

Result:

CFrame:

workspace['7z99'].HumanoidRootPart.CFrame = CFrame.new(0,20,0)

Result:

Another thing, joints are more reliable than :SetPrimaryPointCFrame as that function can cause floating point errors. That bug is as old as time itself and it’s honestly really annoying.

:SetPrimaryPartCFrame() gradually offsets component parts

I made an animated barrier thing that uses :SetPrimaryPartCFrame() to move portions of the barrier. Here is its progress over time: When I first open it up in run mode: [image] I minimized studio and left it alone for a while. A little short of an hour later and it’s turned into this: [image] Notice how some of the pieces are no longer connected. Leaving it for a day resulted in this: [image] Here is a picture that shows the individual models: [image] local interpolation = require(scri…
