This Firework System differs from standard fireworks. It utilizes Niagara on the GPU. Since Event Handlers do not work on the GPU, but there is a need to generate a large number of particles while maintaining good performance, this system operates as follows:

Fireworks Launcher – The fireworks are launched by a Blueprint that triggers the Fireworks Rocket using linear velocity at random angles (determined by the user).
- This approach avoids using Niagara Event Handlers, allowing the system to utilize the GPU to handle large numbers of particles with optimal performance.
Fireworks Rocket – This is the Blueprint for the launched fireworks. Information is passed to the newly created rocket, which, after its lifetime expires, will trigger a Niagara explosion effect.
Settings - The settings are divided into three sections: Rocket, Explosion, and Trail.
- Rocket settings: flight speed, lifetime, flight angle, texture, colors, size, and rotation.
- Explosion types (9 modules): Blast, Disc, Image, Radial, Ribbons, Sparkler, Splash, Tails 1, Tails 2.
- Trail types (3 types): Simple Sparks, Spiral Sparks, Smoke.
