Sandstorm

Bedrock/Snowstorm compatible particle engine but for fabric, java - using polymer for packet-based display entities

Use the webapp snowstorm.app (or VSCode extension or app from Microsoft Store) to create particle effects.

Command

/sandstorm <effect> [position]

Adding effects

Custom effects can be added by placing the particle json files from snowstorm in config/sandstorm/particles

Issues

• Very "long" numbers can't be parsed by the molang compiler (Ex: 0.4398741874364278346234372)
• Transparency is not supported yet (switch to text display entities?)
• Molang expression support for UV mappings is limited due to resource-pack limitations in minecraft java edition
• No support for bezier_curve-type curves
