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));
}
