I'm trying to do a hell-bullet game , so more than maybe 2000-5000 entities in the screen but i can't find a good way to do batching.
I found some c/c++ code to make SFML batching but i'm no genius so i dont understand how to translate it into C# code !
Others things the documentation show off some C++ way to extend SF::Drawable and SF::Transformable.
I can't find C# documentation , if anyone could tell me how to batch eitheir Vertex or Sprite in C# in a good way.
As of now the vertex batching i made , make it hard to apply rotation or animation , when I apply rotation to a renderstates it make my vertex texture dissapear i don't know why !
I'm ready to pay for some help if anyone has clue on how to fix this in C sharp , her my discord :: https://discord.gg/srzchsKDEq

I'm thinking of making everything a sprite , then cycle trought all of them every frame then put it into a vertexarray , but i dont know if it is a good idea ,
VA = new VertexArray();
foreach(sprites){
vertex = new Vertex();
vertex.position = sprites.getPosition();
vertex.texture.position = sprite.GetTexturePosition();
VA.AddVertex(vertex);
}
window.Draw(VA,Renderstates);
something around those lines would work i think.

Hi. I just noticed this post.
I've recently created a simple sprite batcher that may be of some use to you. It's in C++ but it's very simple and short so you should be able to easily convert it to C# or, at least, use it as a base for building your own!
See this thread here:
https://en.sfml-dev.org/forums/index.php?topic=29286.msg180697#msg180697
It has a link to the SFML wiki page that explains it.
Hope it helps!

Using a VertexArray or VertexBuffer in SFML.Net is a bit trickier than maybe in C++, but if you need an example, I've converted on of my talks from C++ to C# here (https://github.com/eXpl0it3r/Talks/blob/master/2023%20-%20Team%20Meeting/SFML%202D%20Graphics/VertexArraysBuffers/Program.cs).
