SpriteRenderer

Introduction

The SpriteRenderer class is responsible for performing MonoGame/FNA-based rendering. It exposes an interface similar to SpriteBatch, but it provides additional functionality including storing a stack of states and providing information about state changes which can be useful for diagnostics.

Accessing SpriteRenderer

The SpriteRenderer lives as an object in the Renderer class and can be accessed through the Renderer instance. For example, you can access the SpriteRenderer as shown in the following code:

LastFrameDrawStates

Introduction

LastFrameDrawStates is an IEnumerable for the draw states used in the previous draw call. This can be used to find performance problems and isolate what may be causing state changes.

Viewing State Changes

The following code can be used to output state changes to the Output window in Visual Studio

Viewing State Changes

The following code can be used to output state changes to the Output window in Visual Studio

// It's best to use some condition rather than reporting
// this ever frame to avoid spamming the output window:
if(someCondition)
{
    foreach (var item in SystemManagers.Default.Renderer.SpriteRenderer.LastFrameDrawStates)
    {
        foreach (var changeRecord in item.ChangeRecord)
        {
                System.Diagnostics.Debug.Output.Write(
                        "Texture {changeRecord.Texture} by {changeRecord.ObjectRequestingChange}");
        }
    }
}
