Shader affecting other Renderer

    auto& reversedShader = co::Assets::Get<co::Shader>("reversed"); --- 1

    glm::vec2 pos = { 0.f, 0.f };

    auto sprite = co::SpriteRenderer(); --- 2
    auto reversed = co::SpriteRenderer(&reversedShader); --- 3

    // Game loop
    while (window.IsRunning())
    {
        window.Clear({ 79, 98, 128 });

        sprite.Draw(flappyBird, pos); --- 4

This is some of my code.

• 1
  reversedShader is a co::Shader& variable, which is a shader that renders objects with reversed colors.
• 2
  sprite is a co::SpriteRenderer variable, which is a renderer with default shader. This renders objects normally.
• 3
  reversed is a co::SpriteRenderer variable, which is a renderer with reversedShader. This renders objects with reversed colors, as the shader does.
• 4
  This code is NOT using reversed, I'm using sprite to render my flappyBird sprite with normal colors.

The problem is - the flappyBird looks reversed at the result. Even though it's rendering with normal shaders, normal renderer. I checked VS debugger and says each renderers are using different shader data. I am really confused.

I will show you my other codes if they are needed.

• Edit.
  I found that it works as I want if I change some lines.
  FROM

    auto sprite = co::SpriteRenderer(); --- 2
    auto reversed = co::SpriteRenderer(&reversedShader); --- 3

TO

    auto reversed = co::SpriteRenderer(&reversedShader); --- 3
    auto sprite = co::SpriteRenderer(); --- 2

Seems like they are working like a static or singleton class. Really confusing

I figured it out, this is because OpenGL uses a global state.
