4000.0.0-alpha.27

[4000.0.0-alpha.27] - 2026-03-19

Added

• Added debug.warn() to log warning messages (#1028) - @lajbel
• Added debug.logMessage() to log a messages array with a wrapping style
  (warn, error, info) (#1028) - @lajbel
• Added per-sprite and per-font filter options, which override the global
  texFilter and fontFilter options (#1050) - @dragoncoder047
• Added global fontFilter option to control default font rasterization filter
  (#1050, #1052) - @dragoncoder047
• Added tileMode option to 9-slice sprites with four tiling strategies:
  'none' (stretch all), 'edges' (tile edges only), 'center' (tile center
  only), and 'all' (tile both edges and center) (#996) - @JustKira
• Added a calculate() method to the internal FPS counters, so advanced users
  can access them to create their own FPS monitor (#1010) - @dragoncoder047
• Added Intl.Segmenter-based grapheme splitting for proper Indic language
  support, via the locale option in DrawTextOpt (#1013) - @shajidhasan
• Added topMostOnlyActivate kaplay option. When true, only the topmost object
  will receive clicks. This avoids problems in a UI where elements overlap -
  @mflerackers
• Added a fill() component - @mflerackers
• Added lerpAngle() helper function to interpolate between clamped angles,
  preventing 360° spins during transitions from 180 to -180 (#1054) -
  @imaginarny
• Added piecewiseBezier() and piecewiseCatmullRom() to evaluate curves with
  multiple points - @mflerackers

Removed

• (!) The texture uv coordinates for primitives (solid- or gradient-filled
  circles, rectangles, lines, and polygons) have now been changed to (1, 1)
  instead of (0, 0), so shaders written for primitives will need to be updated.
  (#1021) - @dragoncoder047

Changed

• (!) The global onDraw() handler's no-tag form now always draws before
  all game objects are drawn, regardless of whether it was attached after game
  objects were added (#977) - @lajbel
• (!) The sprite data format has been changed to allow individual frames to
  be on different GPU textures. Now SpriteData.tex doesn't exist, and
  SpriteData.frames is a list of Frames instead of a list of Quads. A
  Frame contains tex and q (quad) properties that contain that data.
  (#1021) - @dragoncoder047
• Updated the texture packer to use a new packing algorithm which may get more
  sprites onto the same texture, improving graphics batching performance
  (#1011) - @dragoncoder047
• Updated all sprite and font loading to pack everything in the same texture to
  allow it to all batch together, for speed and efficiency (#1021) -
  @dragoncoder047
• Added spritesheet repacking, so spritesheet images that contain lots of blank
  space don't waste texture memory (#1021) - @dragoncoder047

Fixed

• Fixed vertical alignment of text within a now-consistent bounding box across
  browsers (#1053) - @imaginarny
• Fixed tiled mode drawing of sprites ignoring opacity when it was 0 (#1020) -
  @dragoncoder047
• Now, all global events handlers are available in scopes, app.onXXXX and
  scene.onXXXX() (#977) - @lajbel
• Fixed input events attached to paused ancestors not being paused (#1009) -
  @amyspark-ng, @dragoncoder047
• Fixed type UniformValue union not including Texture, a valid option
  (#1018) - @dragoncoder047
• Text component no longer hangs if the requested width is too narrow for a
  single character - @dragoncoder047
• Fixed input events attached to paused ancestors not being paused (#1009) -
  @amyspark-ng, @dragoncoder047
• Fixed type UniformValue union not including Texture, a valid option
  (#1018) - @dragoncoder047
• Fixed event crash when using onLoad or other events that doesn't return an
  EventController, and then using go() (#1024) - @lajbel, credits to
  @dragoncoder047
• Fixed the unexpected behavior of not preserving the aspect ratio in
  drawSprite (#1026) - @benhuangbmj
• Fixed onClick() and onCollide() tag variants no longer working -
  @mflerackers
• Fixed destroy() messing up enumeration during update() and
  fixedUpdate(), thanks to @imaginarny for helping to find the cause -
  @mflerackers
• Fixed canvas not resizing to fullscreen on setFullscreen() (#1055) -
  @imaginarny
