@ -38,7 +38,11 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
- Sort inventory button
- Option to change the master volume when window is unfocused
- Crafting stations in towns
- Option to change the master volume when window is unfocused
- Entities now have mass
- Entities now have density
- Buoyancy is calculated from the difference in density between an entity and surrounding fluid
- Drag is now calculated based on physical properties
### Changed
@ -64,10 +68,18 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
- Certain uses of client-authoritative physics now subject the player to server-authoritative physics.
- Dodge roll iframes and staff explosion are now unlocked by default, with points refunded for existing characters.
- Dash melee now stops after hitting something. Infinite dash also now replaced with dash through.
- Collisions, knockbacks, jumping and drag are now physical forces applied to the entity's body mass
- Turning rate has been made more consistent across angles
- Gravity has been lowered so that physics can work more reasonably
- Jump has been decreased in height but extended in length as a result of the new gravity
- Fall damage has been adjusted with the new gravity in mind
- Projectiles now generally have a different arc because they no longer have their own gravity modifier
### Removed
- Removed command: "debug", use "/kit debug" instead
- Gravity component has been removed
- In-air movement has been removed
### Fixed
