How can I access uResolution in fragmentSource?

[SSShooter]

I want to use a fragment shader which use u_resolution.

[asturur]

where does u_resolution comes from?

We have uStepW and uStepH
uniform float uStepW; uniform float uStepH;
That tells you ( if i recall correctly ) how much percentage of the image each pixel is

Great! that's what I need! Thank you so much😆
