Manual Particle Systems

Introduction

Particles may require a large number of FlatRedBall Sprite instances. This guide shows how to create an incredibly efficient particle system using manual particle sprites.

What is a Manual Particle Sprite?

Manual sprites are sprites which the engine does not automatically update every frame. Manual sprites are an efficient alternative to automatically-updates sprites (the default) if:

The sprite does not change often (such as a static background object)
The sprite changes frequently, but only uses a subset of variables that change every frame

The term "particle sprite" implies it is used for particle effects, but technically a particle sprite is pooled - supporting rapid addition and removal without any memory allocation.

Code Example

The following code is written in a screen which has access to a Texture2D called Texture. Notice that it creates sprites very quickly (60 per second), and even at large numbers the game will run at a reasonable speed:
