FlashTrainer

1. Simulation & Parameters

• 2 Flash Simple Simulation — Military Flashbang, Spherical Flash

• Customizable Parameters — Fuse time (0.2s~3.0s), Throw speed (10~100), Full blind angle (0°~179°), Partial blind angle (1°~180°)

• Blind & Recovery Control — Blind hold duration (0.1s~10.0s), Blind fade duration (0.1s~5.0s), Dynamic interpolation angle recovery

2. Spawner & Training Modes

• 2 Trigger Modes — Manual spawner hotkey ( key), Auto-loop spawner (Home key) (Switch seamlessly anytime)

• Spawn Delay Range — Min spawn delay (0.1s~60.0s), Max spawn delay (0.1s~60.0s) (With value lock validation)

• Chain Flash Mechanism — Chain flash probability slider (0%~100%, Default 0%)

• One-Key Menu Return — Press END to instantly exit training mode and return to the config menu

3. Evasion & Response

• Directional Movement Evasion — Supports W, A, D key movement evasion simulation

• Evasion Tuning — Evasion required time (0.1s~3.0s), Simulation speed (0~30)

4. Visual & Eye Care

• Opacity Slider — Flash opacity adjustment (0%~100% with real-time percentage display)

• Eye Protection Mode — Toggle dark flash screen to reduce eye strain during long practice sessions

• Transparent Overlay — Native borderless transparent rendering via Windows DWM

5. Input & Multi-Monitor Calibration

• RawInput Engine — Captures physical mouse delta via background thread with zero latency and zero simulated inputs

• 360° Calibration — Press L in-game for instant viewport calibration mapped directly to your DPI and in-game sensitivity

• Auto Profile Binding — Automatically saves distinct calibration profiles for different games, DPIs, and sensitivities

• Multi-Monitor Support — Enumerates display setups and lets you assign the Overlay to any target monitor

6. Custom Audio Engine

• Custom Audio Import — Load local throw and explosion sound files (.wav / .mp3 / .ogg, Optional)

• Smart Sound Trimming — Automatically trims explosion audio down to 0.5s in memory for clean, non-overlapping bursts

• Corrupted Path Self-Healing — Automatically clears missing file paths and reverts safely to defaults

• Master Volume Control — Volume slider (0%~100%)

7. Smart Window Management

• Dual-State Transition — Menu mode automatically un-sets topmost status (allowing easy alt-tabbing or clicking other apps); Training mode switches to full overlay topmost rendering with input pass-through

• Native UAC Manifest — Requests admin privileges clean at launch via app.manifest, avoiding double Splash Screen reloads and resolving in-game input blocking

8. Preferences & Profiles

• Save/Load Configurations — Automatically saves DPI, sensitivity, game presets, custom audio, and calibration profiles (Supports Steam Cloud)

• One-Key Reset — Quickly restore default parameter configurations

• Multi-Language — Simplified Chinese and English (Toggle anytime from launch or menu screens)

• Clean Exit — Safe in-app quit button ensures RawInput hooks detach cleanly from the system

9. Notes & Disclaimer

• Borderless Windowed or Windowed Fullscreen mode is required for target games

• Always use the in-app "Quit" button to ensure RawInput hooks detach safely

• This software is an independent training tool for reaction and muscle memory, and does not replicate or replace specific mechanics of third-party games

• Utilizes native Windows RawInput passive listening and external Overlay rendering—free of memory access, process injection, or input automation

• Configuration and calibration files can be saved to Steam Cloud
