EditorGUI.CurveField

Parameters

Returns

AnimationCurve The curve edited by the user.

Description

Make a field for editing an AnimationCurve.

Curve field in an Editor Window.

#pragma strict

// Makes the selected GameObject follow the animation curve.
//
// Usage: Generate the curves for X,Y and Z axis of your desired GameObject
// Select a GameObject and click Generate Curve.
// Press Play and see your object moving.
// Note that this is an Editor script.

This is the run-time script which animates the attached GameObject:

// the editor script to call the SetCurves() function.
 
var curveX : AnimationCurve;
var curveY : AnimationCurve;
var curveZ : AnimationCurve;

function SetCurves(xC : AnimationCurve, yC : AnimationCurve, zC : AnimationCurve) {

                                curveZ.Evaluate(Time.time));
}

// Note that this must be FollowAnimationCurve.cs
