Hi.proandrius.I upload my Editor Package here.I Simplyfied The Code .I don't know what's problem. UnityEditor's Bug?This Editor Bug? I am not sure.

Do it Like this.

1、Create a Test Project.using the default empty scene is ok.
2、Import iTS.unitypackage(uploaded file by me) into Project.
3、Drag The "Assets\iTS\Prefabs\iTSManager.prefab" into currrent empty Scene.
4、Keep the iTSManager node in hierachy Selected。Click some Button in Inspector panel。You'll find It is fine.No problem.
5、Toggle The "Settings Button". First Press"Reprocess lane points " then Press "Reprocess connectors points" button.

6、wait a while.Click any button in this inspector. The unity Editor Response very very slow now!

7、But wait a long time .The Editor come to nomal.But if you click any button. It need to wait also a longtime to do sth.

8、When I Trace and Debug the Code after click.All the function returned immediately.but after returned.The Unity Editor Get blocked.

I don't know why/ Help me proandrius. Point me what's problem

 

Reprocess lane points " rebuild the lane structure by current new settings ( new resolution) .then it will use old lane 's start_point,end_point.and middle interpolate key points which is used by spline math algorithm.to genertate more step points by resolution.

Same with "Reprocess connectors points" except it is the connector bettwen two lanes.

 

I just want to know why it cause unity Slow.Just give me some tips to solve it. This Asset works well.Every process returned normaly .But why Unity Process is Blocked under some condition.

It is not render reason. becase event remove the OnSceneGUI. it is still blocked for a long time.

I switched to unity 5.0/ still have this problem.

Data memory is too big? it is not so big.

Help .Help.Thank you very much!

 

And do u know if it is worth to develop unity plugin to put it on Asset Store.

I have developed a road maker engine. It is Better than EasyRoad and others. but i found they didn't put the next new version onto unity's Asset Store. anymore.

later i will upgrade it to be a city engine for unity ,unity users can use it as a Leve Editor for Games based on our real city .
something like your great ProTile Map Editor.

 

But When I Click Play button .Make the Game to be running.Then bring the scene tab To be forground .Then click any button on inspector .there's no problem. ! So weird problem!

 

OK ! I have solved the problem.I think it is a bug of unity .
I Avoid this bug by using a trick!

The problem is :
If My Script derived from MonoBehaviour has a long array (For example "public TSLaneInfo[] lanes;") to serialize。Then Unity will response too slow!
My trick is:
Declare a same array in the Editor Script related with that script(derived from MonoBehaviour)
public TSLaneInfo [] temp_lanes;
int the end of function "void OnInspectorGUI()"
I add

if (GUI.changed)
{
manager.lanes = null;/*new add*/
EditorUtility.SetDirty(manager);
}
Then in the function of "OnSceneGUI()" I Add some code like below:

if (manager.lanes == null && temp_lanes != null)
{
manager.lanes = temp_lanes;
}

Then there's no problem now! All click response quickly!

Is it a bug of UnityEditor??

Thank you all the same proandrius.

 

IF unity think it's not fair to the asset vendor. you can delete this topic!
If Unity think it is unity's Bug.you can tell us it actually is and fix it later.
