Trail Presets — Elytra Contrails Wiki

Trail presets are stored as JSON files, and can be used by players to save and restore their trail settings.

Exporting and Importing Presets

Every element in a preset file will apply itself to the user's "Your Trails" settings. When exported from in-game, the preset file contains every single setting from that tab. Exported trail configs go to the user's minecraft directory/config/elytratrail_presets folder, and are loaded from there as well.

Here is what the "default" preset looks like:

{
  "enableTrail": true,
  "enableRandomWidth": false,
  "speedDependentTrail": true,
  "trailMinSpeed": 0.8,
  "trailMovesWithElytraAngle": true,
  "maxWidth": 0.05,
  "trailLifetime": 2.5,
  "startRampDistance": 4.0,
  "endRampDistance": 10.0,
  "color": -1,
  "randomWidthVariation": 0.5,
  "prideTrail": "",
  "fadeStart": false,
  "fadeStartDistance": 1.0,
  "lifeTimeFade": true,
  "glowingTrails": false,
  "translucentTrails": true,
  "wireframeTrails": false,
  "alwaysShowTrailDuringTwirl": false,
  "prideTrailRight": "",
  "increaseWidthOverTime": false,
  "startingWidthMultiplier": 1.0,
  "endingWidthMultiplier": 5.0,
  "distanceTillTrailStart": 0.0,
  "endDistanceFade": false,
  "endDistanceFadeAmount": 1.0,
  "speedBasedAlpha": false,
  "minAlphaSpeed": 0.75,
  "maxAlphaSpeed": 2.0,
  "speedBasedWidth": false,
  "minWidthSpeed": 0.75,
  "maxWidthSpeed": 2.0,
  "trailMovesWithAngleOfAttack": true,
  "useColorBoth": true,
  "colorRight": -1,
  "wingtipVerticalPosition": 0.5,
  "wingtipHorizontalPosition": 1.0,
  "wingtipDepthPosition": 1.0,
  "distanceTillTrailEnd": 0.0,
  "aoaBasedAlpha": false,
  "minAlphaAOA": 10.0,
  "maxAlphaAOA": 90.0,
  "aoaBasedWidth": false,
  "minWidthAOA": 10.0,
  "maxWidthAOA": 90.0,
  "edgeFade": false
}

Presets do NOT need to have every config option in them, that is just how they are exported by default.

This is still a valid Preset, And it will only change those settings when it is applied:

{
  "speedDependentTrail": true,
  "trailMinSpeed": 0.8,
  "color": "#FF00FF00"
}

Colors can be stored as hex strings, or directly as integers. Both of these colors will load as white:

{
  "color": "#FFFFFFFF",
  "useColorBoth": false,
  "colorRight": -1
}

Resource Pack Presets

To define new presets with a resource pack, put them in your resource pack in assets\elytratrails\config_presets. In game, users will be able to choose them in the "Presets" tab just like any other presets. These cannot override the built in presets, but you can make new ones.
