comment How to set multiple times, in a single spritebatch, the same pixel shader parameter
I did a kind of in OpengGL with LWJGL, code my own renderer to have only one pass to draw all sprite. But spriteBatch have deferred renderer which make this already. I don't know if it can help me to make my own one. But an other param of draw function on spritebatch is Color params, I know that I can change this filter but how it works ? It's a shader ? If yes do you know how they change this to the pipeline renderer ?

Thank for the answer, It works in immediate render but performance are horrible... I don't know yet how QuadRenderer can help me, where is it and how to build it. There is really no other method to pass a var in shader depending on object ? It looks like a big limitation so I think I didnt get it...

If end()/begin() my SpriteBatch it works but perf are lower of course. I'm sure there is an other way to do that...

I try bind only one time on a variable in my code, same probleme, no change when I change C# variable.

I try Scene.getInstance().ShaderEffect.Parameters["MyParameter"].GetValueVector4Array‌​(1).SetValue(/*new random vector4*/,0); without success.

Ok, as you say it's better to make a new answer for the correct response.

I resolved my issue by calculating tile elligeable to be the center of the screen. Then, I pick up the nearest one of the camera and, after a rotation, I put it back to the middle of the screen. It's a quite easy like this but finally I have to calculate the tile in the center of my screen (because Z axis).
