From 49426f19cd8eaed7cf6c47999b66fee7ee637a56 Mon Sep 17 00:00:00 2001 From: Maze Winther Date: Fri, 27 Feb 2026 16:33:57 +0100 Subject: feat: implement keyframe animation system Add keyframe support for transform, opacity, and volume properties. Includes animation engine (interpolation, mutations, resolvers), timeline markers with selection/snapping, properties panel toggles, keyframe-aware renderer, and full undo/redo command support. Also refactor element command constructors to object params, extract timeline pixel math to pixel-utils.ts, and update cursor rules. --- .../timeline/element/update-element-start-time.ts | 21 +++++++++++++++------ 1 file changed, 15 insertions(+), 6 deletions(-) (limited to 'apps/web/src/lib/commands/timeline/element/update-element-start-time.ts') diff --git a/apps/web/src/lib/commands/timeline/element/update-element-start-time.ts b/apps/web/src/lib/commands/timeline/element/update-element-start-time.ts index 51dcb63d..e25bc0e3 100644 --- a/apps/web/src/lib/commands/timeline/element/update-element-start-time.ts +++ b/apps/web/src/lib/commands/timeline/element/update-element-start-time.ts @@ -5,12 +5,19 @@ import { enforceMainTrackStart } from "@/lib/timeline/track-utils"; export class UpdateElementStartTimeCommand extends Command { private savedState: TimelineTrack[] | null = null; + private readonly elements: { trackId: string; elementId: string }[]; + private readonly startTime: number; - constructor( - private elements: { trackId: string; elementId: string }[], - private startTime: number, - ) { + constructor({ + elements, + startTime, + }: { + elements: { trackId: string; elementId: string }[]; + startTime: number; + }) { super(); + this.elements = elements; + this.startTime = startTime; } execute(): void { @@ -20,7 +27,7 @@ export class UpdateElementStartTimeCommand extends Command { const currentTracks = this.savedState; const updatedTracks = currentTracks.map((track) => { const hasElementsToUpdate = this.elements.some( - (el) => el.trackId === track.id, + (elementEntry) => elementEntry.trackId === track.id, ); if (!hasElementsToUpdate) { @@ -29,7 +36,9 @@ export class UpdateElementStartTimeCommand extends Command { const newElements = track.elements.map((element) => { const shouldUpdate = this.elements.some( - (el) => el.elementId === element.id && el.trackId === track.id, + (elementEntry) => + elementEntry.elementId === element.id && + elementEntry.trackId === track.id, ); if (!shouldUpdate) { return element; -- cgit v1.3.1
