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));
    }
