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);
    

    @MenuItem("Examples/Create Curve For Object")
    static function Init() {
        var window = GetWindow(FollowCurve);
        window.Show();
    }
    
    function OnGUI() {
        curveX = EditorGUILayout.CurveField("Animation on X", curveX);
        curveY = EditorGUILayout.CurveField("Animation on Y", curveY);
        curveZ = EditorGUILayout.CurveField("Animation on Z", curveZ);
        
        if(GUILayout.Button("Generate Curve"))
            AddCurveToSelectedGameObject();
    }
    
    function  AddCurveToSelectedGameObject() {
        if(Selection.activeGameObject) {
            var comp : FollowAnimationCurve = 
                Selection.activeGameObject.AddComponent.<FollowAnimationCurve>();
            comp.SetCurves(curveX, curveY, curveZ);
        } else {
            Debug.LogError("No Game Object selected for adding an animation curve");
        }
    }
}

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));
    }
