EditorGUILayout.CurveField

Parameters

Returns

AnimationCurve The curve edited by the user.

Description

Make a field for editing an AnimationCurve.

Create an animation on the different axis and assign it to a GameObject.

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


class FollowCurve extends EditorWindow {


    var curveX : AnimationCurve = AnimationCurve.Linear(0,0,10,10);
    var curveY : AnimationCurve = AnimationCurve.Linear(0,0,10,10);
    var curveZ : AnimationCurve = AnimationCurve.Linear(0,0,10,10);

    static function Init() {

}

And the script that works with the example:

// This script has to go outside of the Editor Folder.

var curveX : AnimationCurve;
var curveY : AnimationCurve;
var curveZ : AnimationCurve;

function SetCurves(xC : AnimationCurve, yC : AnimationCurve, zC : AnimationCurve) {
    curveX = xC;
    curveY = yC;
    curveZ = zC;
}
function Update() {
    transform.position = Vector3(curveX.Evaluate(Time.time),
                                 curveY.Evaluate(Time.time),
                                 curveZ.Evaluate(Time.time));
}

using UnityEngine;
using System.Collections;

public class FollowAnimationCurve : MonoBehaviour
{
    public AnimationCurve curveX;
    public AnimationCurve curveY;
    public AnimationCurve curveZ;

    public void SetCurves(AnimationCurve xC, AnimationCurve yC, AnimationCurve zC)
    {
        curveX = xC;
        curveY = yC;
        curveZ = zC;
    }

    void Update()
    {
        transform.position = new Vector3(curveX.Evaluate(Time.time), curveY.Evaluate(Time.time), curveZ.Evaluate(Time.time));
    }
}
