Particle systems are a powerful technique used in games and visual applications to simulate complex effects like fire, smoke, rain, explosions, or magical sparkles. Instead of drawing a single object, you create and animate many small elements—called particles—each with its own properties such as position, velocity, size, color, and lifespan. By updating and redrawing these particles over time, you can achieve dynamic and visually rich effects that would be hard to create with static images alone.

You can customize particle effects in many ways by changing the properties and logic used for each particle. Adjusting attributes like color, size, velocity, and lifespan allows you to create effects that match your creative vision. For example, you might randomize the starting position and velocity for a burst effect, fade out particles by lowering their opacity as their life decreases, or use different shapes and blend modes for unique visuals. By tweaking these behaviors, you can simulate anything from glowing embers to drifting snowflakes.
