tremble 1.2.9

A Simple Flutter game engine.

1.2.9

• [BREAKING] Camera constructor now requires viewportWidth and viewportHeight. The x / y constructor params and the position field were replaced by x / y getters and setters.
• [BREAKING] Camera.aabb is now a getter instead of a method - it no longer takes width / height and is derived from the viewport and zoom.
• Camera.centerX / centerY getters and setters added for anchoring the camera on a world point.
• Camera.setViewport added. Changing the viewport or zoom now keeps the camera centered on the same world point.
• Camera.start applies the scale before the translate (previously the translation was incorrectly scaled) and Camera.stop now only restores the canvas if the camera itself started it.
• Camera.shake now shakes in world space (the offset is scaled by zoom) and always restores exactly the pre-shake position.
• ScreenController.keyRepeat added - GameArea now forwards KeyRepeatEvents to it.
• GameArea keyboard handler now returns true to mark the event as handled.
• GameArea preload reworked with a generation counter so restarting preload (e.g. when the controller is swapped) reliably cancels stale progress callbacks.

1.2.8

• [BREAKING] Grid is now generic - Grid<T>. Grid.empty renamed to Grid.filled and now requires a value.
• [BREAKING] Grid no longer imports Flutter. Grid.draw, Grid.forEachDrawArea, Grid.debugDraw, Grid.debugPalette, Grid.toJson1d and Grid.toJson2d moved to the IntGridX extension on Grid<int>. debugDraw now accepts a palette parameter.
• [BREAKING] AABB.copyWith and Circle.copyWith removed. Replaced by Shape.clone() - AABB.clone(), Circle.clone() and Line.clone() added.
• Sweep introduced - expand, expandAABB, expandCircle, expandAABBAndCircle, expandCircleAndAABB for swept collision (Minkowski-style expansion of a moving shape against a target).
• Minkowski.getPenetration sign convention flipped so the penetration vector points outward from the overlapping AABB.
• Ray direction now uses normalized() instead of normalizing the passed vector in place.
• analysis_options.yaml now excludes platform and build directories from analysis.

1.2.7

• SpriteBatch.draw now accepts AABB? cullArea.
• SpriteBatch.getEnum updated.

1.2.6

• CollisionDetector.shapeToShape added - detects collisions between any two Shapes.
• Vec2.damp and Vec2.moveTowards added.
• Grid extended: clone, screenToGrid, neighbor helpers (hasNeighbor*, *NeighborTile), forEachNeighbor4 / forEachNeighbor8, neighborTiles4 / neighborTiles8.
• Grid.draw and Grid.debugDraw added for easy tile map rendering.
• Grid.setTile2dScreen now floors coordinates correctly for negative values.
• TileMap culling fixed for negative positions and assert added for empty tileAreas.
• Camera translate sign fixed.
• SpriteBatch.getAnimation now returns a typed AnimationData<T>.

1.2.5

• Modulate bug fixed.

1.2.4

• Faster TileMap rendering.

1.2.3

• [BREAKING] AssetName interface removed. Enums must override toString() instead of implementing AssetName.
• [BREAKING] SpriteBatch.draw signature changed: Paint? parameter removed, BlendMode is now a named param.
• [BREAKING] Rect.grid renamed to Rect.gridByCount.
• SpriteBatch.fromOldGdxPacker removed - use fromGdxPacker instead.
• SpriteBatch.getRect removed - use getTexture instead.
• SpriteBatch.getEnum added - generates enum code from atlas for debugging.
• SpriteBatch.paint made public.
• Raycaster.raycastGrid param tileSize renamed to cellSize.
• Rect.gridBySize added - splits rect into cells of a fixed pixel size.
• Helpers.toCamelCase added - converts snake/PascalCase strings to camelCase.
• Helpers changed to abstract final class.
• Grid and TileMap classes have been introduced.
• FixedUpdate and lifecycleChanged added (1.2.2 items, now released).

• RigidBody, CollisionResolver, SpatialHash, Raycaster, Minkowski introduced.
• AABB, Circle and Line classes got a draw(canvas, color) function.
• draw function added to Vec2.
• .circle getter added to AABB and .aabb getter added to Sprite.
• SpriteBatch .getAnimation and .getTexture now expects AssetName implementated object.
• .speed field added to Animation.
• CanvasText introduced.
