WebGL Invalid Operation Error (Warning)

[hilary_craven]

Hello!

 

I was wondering if anyone could help with a benign error I'm seeing in a game my team and I are currently working on:

 

Warning Message:

WebGL: INVALID_OPERATION: uniformMatrix3fv: location is not from current program

 

Background:

We're using a lot of custom shaders and filters, and this seems to be linked to our usage of a custom shader.

 

How safe is it to subclass Shader to make a custom shader, and then apply such an object to an instance of PIXI.Sprite on the shader property?

 

I may have not supplied enough information, so please ask any questions. You can see the error here:

Thank you!

Hilary

You should try to subclass the AbstractFilter class for doing custom shaders, the Shader class requires a bit more work to get working. The error you are getting is pixi trying to set a uniform value that actually doesn't exist in the program. This is likely due to you specifying a uniform that isn't in the program, or one of the built-in uniforms not existing in the program that it is expecting.
