Celestial

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

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.

• 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

Please refer to this page for updating your resource packs to this version of Celestial

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
