SIGILL Exception causing Editor and Runtime Crash

[danilonishimura]

Hi everyone,

Recently we have moved the entire user interface from our game to Scaleform. Everything related to interface updating seems to be working as expected. However, we've been experiencing frequent engine exceptions, sometimes at runtime, sometimes using the editor.

ExecutionEngineException: SIGILL
Scaleform.Movie.Advance (Single deltaTime) (at Assets/Plugins/SF/SFMovie.cs:558)
Scaleform.SFManager.Advance (Single deltaTime) (at Assets/Plugins/SF/SFManager.cs:1174)
Scaleform.SFCamera.LateUpdate () (at Assets/Plugins/SF/SFCamera.cs:339)
GameplayScaleformCamera.LateUpdate () (at Assets/Scripts/Game/ScaleformHUD/GameplayScaleformCamera.cs:37)

The GameplayScaleformCamera.cs is a script that overrides SFCamera and does this:

public override void LateUpdate ()
{
	if (GameScene.instance.gamePaused) {
		if (SFMgr != null){
			SFMgr.Advance (lastDeltaTime);
		}
	} else {
		lastDeltaTime = Time.deltaTime;
		base.LateUpdate ();
	}
}

 We do this so we can manipulate the delta time and keep the ui running independently.

Sometimes the error comes up as soon as I hit play, sometimes it takes a few plays, sometimes it happens after recompiling scripts, sometimes while moving assets around. I can't really figure out what's causing this.

And everytime I see this error, I have to close the editor because it'll freeze (beach ball) as soon as I try to do anything.

I'm experiencing the same error. 

I'm using Unity 4.3.4f1 on Mac OSX 10.9.3

This error might be related with low framerate, as in a faster computer, this error rarely happens.

As I'm on a schedule, I may have to abandon scaleform if I don't find a fix that this week 😕

Any help would be great.

🙂

I think I know why the crash happens. 

It is still a scaleform bug, but there is a way to avoid it.

I have a GameHudController.swf that loads all other game hud elements, all SWF files.

So I have this structure:

GameHudController.swf

  -- PlayerHealth.swf

  -- HealthbarController.swf

  -- etc...

All loaded SWF send an ExternalInterface to Unity, and Unity capture them for the future.

So I have this structure:

GameHudController.cs

  Value playerHealth

  Value healthbarController

When I need to change the players health, or add a new healthbar, or update a healthbar, I make GameHudController Invoke a method. 

Exemple:

playerHealth.Invoke("UpdateHealth", newHealth);

This was working fine, until I got lots of Invoke calls on that HealthbarController. 

In my game many enemies are created, updated and destroyed in a few frames.

I figured that calling all those Invokes would be a performance issue, but it was not that bad actually. But after 2min - 10min I got the same SIGILL error.

So I gave up calling Invoke on LOADED swfs.

If I need to Invoke something, it BETTER be on GameHudController.swf, because thats the only swf that has a mirror class extending Movie in Unity.

Now I'm keeping all logic in the Unity side and using ONLY Direct API calls to modify those loaded SWFs.

This is very limiting sometimes and I hope Scaleform will fix the issue.

[beneton]

One last thing, I'm very disapointed with scaleform support. it's been 2 day and we have NO comment from any scaleform dev.

The forum is the only support available, and it's a desert in here.

This way is pretty hard to develop using Scaleform. 

I hope the community people in Scaleform start paying more attetion to the public. Especially if they want Scaleform to be popular in the indie scenario.

[RichMC]

From Unity Development:

A few questions

-          Is this reproducible by simply calling Invoke repeatedly for a certain number of times?

-          Have you stripped down your project in order to narrow this down?

-          Would you be able to provide a focused reproduction case that clearly displays the problem?
