Unity FireworksThis was originally posted on March 12, 2017 and was rewritten and reuploaded on October 16, 2019
The scene consists of a fireworks spawner game object which randomly instantiates firework rockets around itself which move upwards and, after a random amount of time, explode. The firework sparkles explode outwards by the physics collision engine doing its thing since they are all spawned roughly in the same place. Against a backdrop of a night sky, the effect is decent.
Obviously, since everything is a cube, this Unity scene requires a small amount of artisitic license.
