We don't use that info for anything, and it generates unnecessary diffs every time we bump the minor version (and CI failures if we forget to sync some files from opt-in modules (mono, text_server_fb).

|
|
A mathematic curve.
|
|
</brief_description>
|
|
<description>
|
|
A curve that can be saved and re-used for other objects. By default, it ranges between [code]0[/code] and [code]1[/code] on the Y axis and positions points relative to the [code]0.5[/code] Y position.
|
|
See also [Gradient] which is designed for color interpolation. See also [Curve2D] and [Curve3D].

Adds a point to the curve. For each side, if the [code]*_mode[/code] is [constant TANGENT_LINEAR], the [code]*_tangent[/code] angle (in degrees) uses the slope of the curve halfway to the adjacent point. Allows custom assignments to the [code]*_tangent[/code] angle if [code]*_mode[/code] is set to [constant TANGENT_FREE].
