Created 2d game is vague

I created a 2D game with urho3d, but it’s vague, how can I optimize this to make him as clear as possible.

Sorry, I didn’t make it clear. What I want to say is that my StaticSprite2D display is a little vague, and how to make it clear.

In addition, I also want to ask a question: what is the difference between the SetOrthoSize (float orthoSize) and theSetZoom (float zoom) of the camera component?

Your question is also very vague. But i think this is what you are looking for:

I assume you want point filtering for your textures.

I think it should be this。
