I am very confused, is this an engine bug?
Someone explain this please
targetX = 0
while true do
targetX += 1
print(CFrame.Angles(math.rad(0), math.rad(0), math.rad(targetX)).LookVector)
wait()
end
Output is always -0, -0, -1
targetX = 0
while true do
targetX += 1
print(CFrame.Angles(math.rad(0), math.rad(targetX), math.rad(0)).LookVector)
wait(0.1)
end
Outputs are always changing here
targetX = 0
while true do
targetX += 1
print(CFrame.Angles(math.rad(targetX), math.rad(0), math.rad(0)).LookVector)
wait(0.1)
end
Outputs are always changing here too

This is not a bug. You are rotating on the same axis that the LookVector points to. The LookVector points to the direction the front of the CFrame is facing. Basically, it tells you where the front of the CFrame is facing and also, the direction the CFrame's Z axis in its local space is facing.
This is best explained with visualization though. Here's a part with a few attachments: one that points in the direction that the axes face (except the front one, since the LookVector points in the -Z direction). Here is the image link which shows each attachment and identifies them
In the following gif, the part gets rotated on the Z axis. Here is the gif
Notice how the front attachment doesn't move, but the others do, because you are rotating on the same axis that the lookvector points to. You also notice that this result is reflected when you rotate on the Z axis and obtain the LookVector of it. This is also true if you were to rotate on other axes and obtain the respective direction vector that the rotation axis points in.
For example, you can apply a rotation on the X axis, then obtain the RightVector and you notice that the result is the same, or when you apply a rotation on the Y axis, then obtain the UpVector and you also notice that the result is the same
