# In which direction does the Node2D rotation point?

Attention Topic was automatically imported from the old Question2Answer platform.

In this image, which can be found in the `Node2D` docs for `get_angle_to()`, the rotation seems to point in a direction, but `rotation` is only a float, so when `rotation` is 0, where does this point?

Nowhere, rotation is not a direction. You can pick any starting angle and consider the rotation from there.
But in mathematics, when it comes to a unit circle, If I recall correctly it is pointing to the right by default.
And even on this picture, as you can see, Node2D.rotation is relative to the positive side of the x axis (right).

`rotation` is a float and `get_angle_to()` returns a float. The float number of `red_vector.rotation` corresponds to the red angle in image. The float number returned by `red_vector.get_angle_to(point)` corresponds to the green angle in the image.
`rotation` does not point anywhere, but a vector with `rotation` will point as though it is rotated `rotation` radians away from the x-axis. If `rotation = 0` then this will be along the x-axis (this is horizontally right in the image).
