ModernWormfare — Sync PvP Test Results

Overview

Date: 2026-07-22

Mode: SyncLive — real-time live tick loop, all players act simultaneously

Players: alpha (Rocket race) vs beta (Cow race)

Map: Bridge

Server: dev server ./dev.sh on http://localhost:5080

Game ID: a247ee15-5e9f-42d9-8dc5-920d64e10539

Screenshots

1. Sync lobby — host creates a SyncLive game (alpha, Rocket, Bridge)

Sync join — 2. Second player (beta, Cow) joins the open sync game

3. Sync loadout — Ready button (auto-begins when all ready)

Game start — 4. Sync game start — "ModernWormfare Sync — unit 1/3", no submit/recording UI

Alpha view — 6. Alpha's view — same shared world, different loadout/funds

7. Alpha fires a Rocket simultaneously — live combat

Unit cycle — 8. Tab cycles units; A/D moves in real time (sync-only feature)

Pause menu — 9. Escape opens pause menu (Settings / Resume / Leave)

10. Live combat — both players in the same real-time world

Report

What SyncLive means: Unlike Async (turn-batch) and SyncRoundBased (vs AI, one unit at a time), SyncLive is live simultaneous PvP. Both players act at the same time on a real-time server tick loop. No turn rotation, no batch recording, no replay, no submit button. Each player cycles their units with Tab and fires in real time.

Features exercised

1. Sync lobby create + join — PASS

Host (alpha) opened /lobby/sync, set name/race/map, clicked Create Sync Game. Server created a SyncLive game.
beta joined from a separate tab. Players column showed alpha, beta.

2. Loadout + auto-begin — PASS

Both bought items and clicked Ready.
SyncLive auto-begins when all humans are ready (unlike Async's explicit BeginMatch). Server log: began match after all players readied (single=False).

3. Live simultaneous combat — PASS

Both clients showed ModernWormfare Sync — unit 1/3 (no player name — all act at once).
No RECORDING status, no Submit button, no admin toolbar — confirming real-time, not batch.
Both fired weapons within seconds — simultaneous combat confirmed.
Wind 166 px/s (Bridge), shared across both clients.

4. Tab unit cycling + movement — PASS

Tab cycles to next unit (sync-specific: players control any of their units).
A/D movement works in real time (no batch recording).

5. Pause menu — PASS

Escape → pause overlay (Settings / Resume / Leave Game). Resume returned to live play.

Known issues found

1. Sync-mode canvas redraw quirk — NOTE (investigated, expected behaviour)

When idle (no projectile in flight), the canvas appears to show a stale frame. Investigation confirmed the canvas IS redrawn every animation frame via requestAnimationFrame → Tick() → RenderFrameAsync() → drawFrame(). The “stale” appearance is expected: when the world state is static, each redrawn frame is identical. No fix needed.

Conclusion

The SyncLive PvP loop works: lobby → loadout → auto-begin → simultaneous real-time combat with Tab unit cycling and live movement. Both players fired weapons at the same time with no turn rotation. The mode correctly omits async-only UI (recording, submit, replay, admin toolbar). The canvas-redraw quirk was investigated and confirmed as expected behaviour (canvas redraws but frames are identical when the world is static).
