InputBooster

🎉 Major Release

This is the first public release of InputBooster 3.0.0, built for Minecraft 1.21.11 with Fabric Loader 0.19.2.

🐛 Fixed

Critical Crash Fixes

• Startup mixin crash — CallbackInfoReturnable is required In MC 1.21.11, MinecraftClient.doAttack() was changed from void to boolean. Mixin's @Inject on a non-void method requires CallbackInfoReturnable<Boolean> instead of plain CallbackInfo. The onDoAttack handler in GameTickMixin was using CallbackInfo, causing a fatal mixin apply error that crashed the game on launch. Fixed by switching to CallbackInfoReturnable<Boolean> and replacing ci.cancel() with cir.setReturnValue(false).
• Settings screen crash — Can only blur once per frame MC 1.21.11 already triggers a background blur before delegating to a screen's render() method. The old code called renderBackground() manually at the top of InputBoosterScreen.render(), firing the blur shader twice in the same frame and crashing. Removed the manual call; super.render() handles it correctly.
• Matrix stack compile errors (push / pop / scale not found) ctx.getMatrices() in MC 1.21.11 returns JOML's raw Matrix3x2fStack, which has no push(), pop(), or three-argument scale(). Attempts to cast it to net.minecraft.client.util.math.MatrixStack also failed at runtime. Removed matrix stack scaling entirely; overlay size and line spacing are now computed directly from the scale factor in pixel coordinates.

Gameplay Fixes

• Double block break on a single click One left-click was destroying two blocks instead of one. Root cause: InputDrainer.apply() called attackBlock() for block targets while vanilla's handleBlockBreaking() loop was already calling attackBlock() every tick the button was held — two calls per tick. Fixed by removing the attackBlock() call from the drainer for block targets entirely. Block breaking is now driven exclusively by vanilla's continuous held-key loop. Entity hits remain one-shot events and are still fired from the drainer with attackHandledThisTick = true to suppress vanilla's duplicate.
• CPS always showing 0 After the double-block-break fix moved recordClick() into the entity-only branch, block clicks were no longer counted toward CPS. Moved recordClick() up to drainAll() so it fires for every accepted ATTACK_PRESSED event regardless of target type.
• P key can't re-enable mod / O key stops working when mod is off onClientTick had if (!active || !initialized.get()) return at the very top, which meant once P toggled the mod off the entire tick method exited before handleKeybinds() was ever reached. Both P and O became dead keys until the game was restarted. Fixed by moving the handleKeybinds() call before the active guard so both keys always work.

HUD / Overlay Fixes

• Overlay visible during F3 screen The HUD panel rendered on top of F3, making both unreadable. The overlay now checks mc.getDebugHud().shouldShowDebugHud() and returns early, hiding automatically when F3 is open and reappearing when it closes.

---

✨ Added

HUD Overlay

• Always-on HUD panel — renders on the game screen at all times, not only when F3 is open. Automatically hides when F3 is active to avoid clutter.
• Configurable corner position — cycle through Top-Left, Top-Right, Bottom-Left, Bottom-Right from the Advanced settings tab.
• Configurable scale — slider from 0.5× to 3.0× in the Advanced settings tab.
• Semi-transparent background box — drawn behind all overlay lines for readability against any terrain.

Settings Screen (O key)

• Full tabbed GUI with five tabs: Poll Rate, Features, Advanced, Stats, Profiles.
• Poll Rate tab — AUTO/MANUAL mode toggle, poll rate slider (60–1000 Hz), six quick-preset buttons (100 / 200 / 350 / 500 / 750 / 1000 Hz), Burst Mode toggle, Combo Keys toggle.
• Features tab — toggles for Sprint Fix, Auto-Sprint, W-Tap Assist, Anti-Idle, Auto-Strafe, CPS Limiter, and a Max CPS slider.
• Advanced tab — HUD Overlay on/off, Overlay Position cycler, Overlay Scale slider, Action Bar Messages toggle, Debug Mode toggle, FPS Check Interval slider.
• Stats tab — session uptime, recovered inputs, estimated missed inputs, latency info, poll thread status, 60-second CPS sparkline graph.
• Profiles tab — save and load up to 5 named presets (PvP, Mining, Idle, Hybrid, Custom).

Core Features

• Adaptive Burst Mode — automatically spikes poll rate to 1000 Hz for 3 seconds when FPS drops more than 20% in one second, then returns to the configured rate.
• Session Stats tracker — records session uptime, total recovered inputs, estimated missed inputs without the mod, and a rolling CPS history.
• Config Profiles — save and load named configuration snapshots from the in-game screen.
• Latency Profiler — tracks per-drain latency with rolling average and peak value, displayed in the HUD overlay.
• CPS Limiter — configurable cap (1–20 CPS, default 20) with real-time display in the overlay.

Config File

• New keys: overlay_position (integer 0–3, default 0 = Top-Left) and overlay_scale (float 0.5–3.0, default 1.0).

---

🔧 Changed

• HUD is now always-on instead of F3-only. Toggle it via the Advanced tab in settings (O key).
• "F3 Overlay Info" setting renamed to "HUD Overlay" to accurately describe its function.
• Poll rate range expanded from [100, 500] Hz to [60, 1000] Hz.
• onDoAttack mixin now uses CallbackInfoReturnable<Boolean> and setReturnValue(false) instead of CallbackInfo and cancel().
• handleKeybinds() now runs before the active guard in the tick loop.

---

🗑️ Removed

• "Double-hit fix: ON" line removed from the HUD overlay — the fix is always active and the line was noise.
• Manual renderBackground() call removed from InputBoosterScreen.render().
• Matrix stack push/pop/scale calls removed from DebugOverlayManager (incompatible with MC 1.21.11 API).

---

[2.0.2] - 2026-03-30

🐛 Fixed

• "Not Responding" on MC 1.21.11+ — polling thread now checks for interruption and logs errors instead of silently failing.
• CPS never recorded — CpsLimiter.recordClick() was never called from InputDrainer. Fixed.
• Silent polling errors — changed error handling from silent to WARN-level logging.
• Null dereference — added null checks in InputDrainer and GameTickMixin.
• WTapAssist silent failure — added try-catch around onWRelease() so feature errors don't block the drain loop.
• Sleep efficiency — polling thread sleep changed to millisecond precision for better CPU and battery usage.

✨ Added

• Colorful F3 display with status-based color coding (red / yellow / green / gray).
• Visual status indicators (✓ / ✗) for enabled/disabled features in F3.

---

[2.0.1] - 2026-03-29

🐛 Fixed

• Double input drain — InputDrainer.drainAll() was called twice per tick. Removed redundant drain.
• AtomicLong race condition — totalHits and recoveredInputs were volatile long incremented with ++ from multiple threads. Replaced with AtomicLong.
• WTapAssist dead code — FORWARD_RELEASED events were queued but never handled in InputDrainer. Wired up.
• Unsafe MC reads from polling thread — introduced gameReady / gamePaused volatile flags; polling thread reads flags instead of MC objects directly.
• O(n) queue size — ConcurrentLinkedQueue.size() replaced with AtomicInteger for O(1) tracking.
• Poll rate bounds mismatch — internal clamp unified with documented range.

[2.0.0] - 2026-03-27

🎉 First Public Release — Complete Rewrite

Internal v1.0 was never released due to memory leaks, Sodium/Iris crashes, config corruption, and thread-safety issues. v2.0 is a ground-up rewrite.

✨ Added

• Dynamic FPS-aware poll rate (100–500 Hz auto-scaling).
• F3 debug screen integration (poll rate, FPS, recovered inputs, CPS, feature states).
• Real-time CPS tracker with sliding-window algorithm.
• Auto-Strafe correction for diagonal movement at low FPS.
• Anti-Idle protection against AFK kicks during lag spikes.
• Lock-free concurrent input queue.
• Mixin-based event interception compatible with Sodium, Iris, Lithium.
• Graceful thread lifecycle (clean startup and shutdown hooks).
• Properties-file config with validation, bounds checking, and auto-creation.

🗑️ Removed (vs internal v1.0)

• HUD overlay system — replaced with F3 integration.
• Experimental / unstable features.
• MC 1.19–1.20 legacy compatibility modes.
• Built-in macro system.
