PixelPerfectSprite NullReferenceException on Build and Run

[francesco]

When I test my game within the unity editor everything works fine. But when I create a build of the game (x86_64), I am getting a steady stream of null reference exceptions that look like this....


WindowsPlayer(DESKTOP-SOU9P3M)</i> NullReferenceException: Object reference not set to an instance of an object

I think the issue could possibly be related to prefabs. When I create a prefab of an object, the "ProCamera2d" property of the PixelPerfectSprite script shows an error of type mismatch in the inspector.

ProCamera2d Settings




All game objects have the 2dPixelPerfectSprite script attached as far as I can tell.

Hi francesco, thanks for reporting this.

Can you please explain further what's your setup like? What do you have on prefabs?


Cheers!

Luis, 

Sorry for the delay, but it appears my post was moved to the Bug Report section and I did not get an email notification of your response.

In this case, I have a simple test scene. The "map" is made with Tiled and then imported with Tiled2Unity. There are not sprite renderers associated with this. 

Everything else that is visible in the scene are game objects with sprite renderers. For every game object with sprite renderer I have attached the Pro Camera 2d Pixel Perfect Sprite script. Many of these objects are then turned into prefabs.

Attached is an example of one of my prefabs for a playable character. The character is composed of 5 game objects, 4 of which have sprite renderers. The selected sprite in this screenshot represents the body of a playable character. When I take a game object such as this solider from the hierarchy and create a prefab, the Pro Camera 2d object that it is associated with it is then set to "type mismatch".

Please let me know what other details would be helpful in debugging this. 



Thanks,

Francesco

Hi francesco,

Sorry for very late reply.

Thanks for sending that info. I'm going to try to replicate this and get back to you as soon as possible.

Hi francesco,

I've been trying to replicate this issue but I couldn't. I created a prefab with a PixelPerfectSprite and I added the PixelPerfect extension to ProCamera2D. During runtime (on a standalone build) I instantiate the prefab and everything works as expected.

Can you please provide me a small sample project that replicates the issue? (Please share through PM)


Thanks!
