Erik Onarheim feat: Implement Plugin System (#3670) 9d ago

feat: Implement Plugin System (#3670) # New 1st Party Plugin System This allows deep configuration of the excalibur subsystems by providing lifecycle hooks/interception points at every critical juncture to boot the engine. Right now we are mainly focused on renderer/asset type plugins so this initial stab leans in that direction. 1. **Engine construction** — `onEnginePreConfig` → (flags frozen) → `onEnginePostConfig` 2. **Engine start** — `onLoad` → (resources loaded) → `onLoadComplete` 3. **Engine initialize** — `onEnginePreInitialize` → `onEnginePostInitialize` 4. **Graphics context construction** — `onGraphicsPreConfig` → `onGraphicsPostConfig` 5. **Graphics context init** — `onGraphicsPreInitialize` → `onGraphicsPostInitialize` 6. **Scene initialize** — `onScenePreInitialize` → `onScenePostInitialize` 7. **Scene activate** — `onScenePreActivate` → `onScenePostActivate` 8. **Scene deactivate** — `onScenePreDeactivate` → `onScenePostDeactivate` 9. **Graphics context lost/restored** — `onGraphicsContextLost` → `onGraphicsContextRestored` 10. **Engine dispose** — `dispose`

chore: TS6 Upgrades + Typedoc update (#3793) This is a long time coming, TS6 upgrade to all the things AND a new typedoc plugin fork. I decided to abandon the astro port, the more effort I put into it the more I realized it'd be a TON of work to match the features we already have and I didn't want to step backwards in functionality * TS6 IS A THING!!! * API Doc Plugin Fork has been paired down to just our needs and updated to the latest TypeDoc * https://github.com/excaliburjs/docusaurus-plugin-typedoc-api * Build a small custom remark plugin that translates to the API docs paths based on TypeDoc cli generation in `npm run api:generate` * Docusaurus link checking will now break the build to keep our docs from accumulating dead links * Invalid TypeDoc will now break the build as well

perf: Impove text/font rasterization and rendering perf by reducing sizes lossless (#3687) Issue was raised by @JSLegendDev on the discord https://discord.com/channels/1195771303215513671/1471972758136164606/1471985432568004649 Safari doesn't do as well when re-rastering and uploading that to the GPU causing visible hitches in games which is unacceptable. This can be worked around in the current version by reducing `quality` or making the text as static as possible for unchanging glyphs. This PR improves the texture usage and reduces the size of text needed to raster for equivalent or better quality text ## Changes: - Internally we use the smallest possible bitmap to represent the text - Caching lookups are improved by using actual hashing with numbers

fix: update NineSlice rendering logic and add visual test images #3777 (#3782) # Fix NineSliceStretch.Tile clipping behavior ## Description Fixes issue #3777 where `NineSliceStretch.Tile` mode was squashing partial tiles instead of clipping them to fit the destination space properly. ## Problem When using `NineSliceStretch.Tile` mode, the last partial tile would be distorted to fit the remaining space rather than being clipped. This behavior did not match the documented behavior: "takes input slice and paints it across the entirety of the output dimensions in a repeating texture fashion that will not distort the source image at all, but may not fit properly in the destination space, leaving a potentially partial drawing of the texture remaining." **Expected behavior:** Tiles should repeat without distortion, with partial tiles at edges being clipped. **Actual behavior:** Partial tiles were being stretched/squashed to fit the space. ## Solution Modified the `_drawTile` method in `src/engine/graphics/nine-slice.ts` to properly apply clipping when drawing tiled sections. When `NineSliceStretch.Tile` is used, the source dimensions (`srcW` and `srcH`) now correctly reflect the calculated `tempSize` instead of always using the full `targetCanvas` dimensions. The fix ensures that: - When horizontally tiling, the source width uses `tempSize` for horizontal calculations - When vertically tiling, the source height uses `tempSize` for vertical calculations - This allows the canvas clipping to properly handle partial tiles at the edges ## Testing Verified with checkerboard pattern tiling to confirm tiles are no longer distorted when they don't fit evenly into the destination space. ## Related Issues Closes #3777
