A list of keyframes or points on the curve.

Amount of key frames or points on the curve.

The range of this curve. This affects looping.

The value range. This should affect nothing but what it looks like in the editor.

Add given keyframe to this curve.

Add a new keyframe at given position to this curve.

Returns the value on the curve at given time position.

Like evaluate but takes a normalized time between 0 and 1 and returns a normalized value between 0 and 1

If the curve is broken in some way, we can fix it here. Ensures correct time and value ranges, and that the curve has at least one point.

Remove all of the frames at the current time

Make a copy of this curve that is reversed (If input eases from 0 to 1 then output will ease from 1 to 0)

Make sure we're all sorted by time

A curve that eases from 0 to 1

A curve that eases in from 0 to 1

A curve that eases out from 0 to 1

A curve that linearly interpolates from 0 to 1
