Almost a complete rewrite, lots of new features, and better performance. [Please refer to this page for updating your resource packs to this version of Celestial](https://github.com/fishcute/Celestial/wiki/Updating-to-2.0) Performance - Moved to a different expression parsing system, which performs significantly better than the previous one. - FPS no longer drops when rendering large quantities of populate objects. - Overall improved various parts of Celestial, which should result in better performance. Triangle Fan Objects - Added a new type of celestial object: "triangle_fan". Triangle fans can be used to create circular objects and twilight effects. Twilight Objects - Added a new type of celestial object: "twilight". Twilight objects can be used to create custom twilight effects (ex. custom sunrises/sunsets). - As a result, twilight settings in the environment category have been deprecated, and will be removed in an upcoming update. Sky Objects - Changed default base degree rotations for x and z to be 0 degrees. - Added "legacy_rotations" boolean to dimensions.json, which the default base degree rotations for x and z back to -90 degrees. - Changed default values for unset options to be greater than 0. Local Variables - Variables can now be registered directly in a sky object file, within the "local_variables" json object list. - Local variables can only be used in the sky object it was registered in. Vertex List - Added "alpha" and "color" entries to individual vertex points. - Slightly improved vertex list rendering performance. Error Messages - Improved error messages to be more easier to read visually, and to be significantly more useful. - Error messages will state where they occured, and will be slightly more specific as to what is causing the issue. - Error messages will also state if they occured during compilation, or if they occured after. - An error message will now occur when a texture path is invalid. Color Entries - Added global color entries, located in "celestial/sky/color_entries.json". Global color entries are color entries that can be registered and used in place of HEX color values. - Removed "inherit" option from color entries, as "#skyColor" and "#fogColor" can be used instead. Color Entry Overrides - Renamed "alpha" entry to "ratio". - Added "red_ratio", "gren_ratio", "blue_ratio" entries, which control the ratio of each color. - Added "red", "green", and "blue" entries. - Added three new variables for color entry overrides: "red", "green", and "blue" (Returns the RGB values before the color override is applied). Color Entry Blend Types - Added "blend_type" entry, which determines the method for blending the color override with the base color. - Added "linear_interpolation" blend type, which is the default blend type. - Added "override" blend type, which completely overrides the original color. Useful when using the "red", "green", and "blue" variables. Ratios are ignored for this blend type. - Added "lab" blend type, which uses LAB colors instead of RGB colors when blending. Results in much nicer color blend gradients when used. - Added "apply_fog_additions" blend type, which applies additional fog effects from twilight objects. Sky Boxes - Sky boxes can now be rotated using base degree rotation values. - Removed unnecessary "texture" entry in skybox properties Variables and Functions - Removed requirement for variable calls to start with a hashtag. Hashtags will however still be accepted in equations, and will simply be ignored. - Renamed "rainLevel" to "rainAlpha", and changed it to no longer return "1 - (Rain level)". - Renamed "thunderGradient" to "thunderAlpha" - Renamed function "isInBiome" to "inBiome". - Renamed function "isUsing" to "rightClickingWith". - Renamed function "isMiningWith" to "leftClickingWith". - Renamed function "isHolding" to "holding". - Renamed function "isInArea" to "inArea". - Renamed function "distanceToBiomeIgnoreY" to "distanceToBiomeFlat". - Changed function "distanceToBiome" arguments to "distanceToBiome([Distance], [Biome Name]...)". - Changed function "distanceToBiomeFlat" arguments to "distanceToBiomeFlat([Distance], [Y Position], [Biome Name]...)". - Changed function "inBiome" arguments to "inBiome([Biome Name]...)". - Changed function "holding" arguments to "holding([Item ID]...)". - Changed function "leftClickingWith" arguments to "leftClickingWith([Item ID]...)". - Changed function "rightClickingWith" arguments to "rightClickingWith([Item ID]...)". - Renamed variable "isRightClicking" to "rightClicking". - Renamed variable "isLeftClicking" to "leftClicking". - Renamed variable "isSubmerged" to "submerged". - Renamed variable "getGameTime" to "gameTime". - Renamed variable "getWorldTime" to "worldTime". - Renamed variable "getDayTime" to "dayTime". - Renamed variable "xPos" to "posX". - Renamed variable "yPos" to "posY". - Renamed variable "zPos" to "posZ". - Replaced "[Number]m[Min]" format with function "min([Number], [Min]...)". - Replaced "[Number]M[Max]" format with function "max([Number], [Max]...)". - Added variable "bossSkyDarken", which returns the percent of the fog darken effect created by withers/ender dragons. - Added function "colorEntryRed([Color Entry Name])", which returns the red value of a color entry. - Added function "colorEntryGreen([Color Entry Name])", which returns the green value of a color entry. - Added function "colorEntryBlue([Color Entry Name])", which returns the blue value of a color entry. - Added function "modulo([Number], [Divisor])", which returns the modulo of a number. - Added function "repeat([Number], [Lower Bounds], [Upper Bounds])", which clamps a number between two bounds but returns repeating values when going beyond the bounds. - Added function "clamp([Number], [Lower Bounds], [Upper Bounds])", which clamps a number between two bounds. - Added function "lerp([Number 1], [Number 2], [0-1 Ratio])", which returns the linear interpolation between two numbers. - Added function variant of "starAlpha", "starAlpha([Sky Angle])", which allows for a custom sky angle as an argument. - Added function variant of "dayLight", "dayLight([Sky Angle])", which allows for a custom sky angle as an argument. Twilight Functions - Added various functions to help with the creation of custom twilight effects. - Added function "twilightAlpha([Sky Angle])", which returns the alpha of the twilight effect for a specific sky angle. - Added function "twilightProgress([Sky Angle])", which returns how far the twilight has progressed for a specific sky angle. - Added function "twilightFogEffect([Sky Angle])", which returns the alpha of the twilight fog effect for a specific sky angle. Sky Object Properties - Added "blend" option, which determines if the object should have transparency blending. - Removed "red", "green", and "blue" entries, as the "color" entry can be used instead. - Removed "ignore_fog", since it didn't really do anything.
