Running a script in editor mode

Questions & Answers
1

How can I run this script in editor mode? Adding @ExecuteInEditMode to the top doesn’t work. What other ways are there? This script is from Unity’s procedural examples.

var radius = 1.0;
var pull = 10.0;
private var unappliedMesh : MeshFilter;

enum FallOff { Gauss, Linear, Needle }
var fallOff = FallOff.Gauss;

static function LinearFalloff (distance : float , inRadius : float) {
	return Mathf.Clamp01(1.0 - distance / inRadius);
}

static function GaussFalloff (distance : float , inRadius : float) {
	return Mathf.Clamp01 (Mathf.Pow (360.0, -Mathf.Pow (distance / inRadius, 2.5) - 0.01));
}

function NeedleFalloff (dist : float, inRadius : float)
{
	return -(dist*dist) / (inRadius * inRadius) + 1.0;
}

function DeformMesh (mesh : Mesh, position : Vector3, power : float, inRadius : float)
{
	var vertices = mesh.vertices;
	var normals = mesh.normals;
	var sqrRadius = inRadius * inRadius;
	
	// Calculate averaged normal of all surrounding vertices	
	var averageNormal = Vector3.zero;
	for (var i=0;i<vertices.length;i++)
	{
		var sqrMagnitude = (vertices *- position).sqrMagnitude;*

  •  // Early out if too far away*

  •  if (sqrMagnitude > sqrRadius)*

  •  	continue;*

  •  var distance = Mathf.Sqrt(sqrMagnitude);*

  •  var falloff = LinearFalloff(distance, inRadius);*

_ averageNormal += falloff * normals*;_
_ }_
_ averageNormal = averageNormal.normalized;*_

* // Deform vertices along averaged normal*
* for (i=0;i<vertices.length;i++)*
* {*
_ sqrMagnitude = (vertices - position).sqrMagnitude;
* // Early out if too far away*
* if (sqrMagnitude > sqrRadius)
 continue;*_

* distance = Mathf.Sqrt(sqrMagnitude);*
* switch (fallOff)*
* {*
* case FallOff.Gauss:*
* falloff = GaussFalloff(distance, inRadius);*
* break;*
* case FallOff.Needle:*
* falloff = NeedleFalloff(distance, inRadius);*
* break;*
* default:*
* falloff = LinearFalloff(distance, inRadius);*
* break;*
* }*

vertices += averageNormal * falloff * power;
* }*

* mesh.vertices = vertices;*
* mesh.RecalculateNormals();*
* mesh.RecalculateBounds();*
}

function Update () {

* // When no button is pressed we update the mesh collider*
* if (!Input.GetMouseButton (0))*
* {*
* // Apply collision mesh when we let go of button*
* ApplyMeshCollider();*
* return;*
* }*

* // Did we hit the surface?*
* var hit : RaycastHit;*
* var ray = Camera.main.ScreenPointToRay(Input.mousePosition);*
* if (Physics.Raycast (ray, hit))*
* {*
* var filter : MeshFilter = hit.collider.GetComponent(MeshFilter);*
* if (filter)*
* {*
* // Don’t update mesh collider every frame since physX*
* // does some heavy processing to optimize the collision mesh.*
* // So this is not fast enough for real time updating every frame*
* if (filter != unappliedMesh)*
* {*
* ApplyMeshCollider();*
* unappliedMesh = filter;*
* }*

* // Deform mesh*
* var relativePoint = filter.transform.InverseTransformPoint(hit.point);*
_ DeformMesh(filter.mesh, relativePoint, pull * Time.deltaTime, radius);
* }
}
}*_

function ApplyMeshCollider () {
* if (unappliedMesh && unappliedMesh.GetComponent(MeshCollider)) {*
* unappliedMesh.GetComponent(MeshCollider).mesh = unappliedMesh.mesh;*
* }*
* unappliedMesh = null;*
}

You’re using JS so at the top put

@script ExecuteInEditMode()

and the Update and FixedUpdate functions will be run in edit mode every event and every frame while the scene few has focus, if I remember correctly.

Well I would encourage you to look at the unity docs for Editor, and to answer your question,

an editor script looks something like this:

[CustomEditor(typeof(SomeEditor))]
public class SomeEditor : Editor
{
//…
void OnSceneGUI()
{
//logical tick
}

public override void OnInspectorGUI()
{
//draw ui tick
}
