Flashbang script

Flashbang Script - Realistic Stun Grenade System for Tactical Roleplay

Bring authentic tactical combat to your FiveM server with a fully functional flashbang grenade system that actually impacts gameplay. This isn't just a visual effect - flashbangs temporarily blind players, disorient their controls, and can even disable voice chat to simulate the sensory overload of a real stun grenade. Perfect for police raids, SWAT operations, or any server where tactical equipment matters beyond cosmetics.

What's Included

You get a complete weapon_flashbang implementation with configurable effects duration, explosion timer, and impact radius. The script integrates with both Mumble-VOIP and pma-voice to optionally mute affected players during the stun period - simulating the disorientation and hearing damage from a real flashbang. All parameters are adjustable through a dedicated config file, so you can tune the effect intensity to match your server's combat balance.

For QBCore servers, complete integration instructions are included with exact line-by-line modifications for qb-core/shared/weapons.lua, qb-core/shared/items.lua, qb-weapons/client/main.lua, and qb-inventory/client/main.lua. ESX integration works out of the box.

Key Features

• Realistic Flash Effect - Screen whiteout with gradual vision recovery, simulating the temporary blindness from a real stun grenade
• Configurable Timer - Set custom fuse time before detonation (default mirrors real flashbang timers)
• Voice Chat Integration - Optional muting during stun period works with mumble-voip and pma-voice systems
• Adjustable Duration - Control how long players are affected (balance for RP servers vs competitive)
• Custom Sound Effects - Volume-adjustable detonation audio with characteristic flashbang report
• Area of Effect - Configurable range determines who gets stunned based on proximity to detonation point
• Performance Optimized - 0.1ms idle, 0.05ms max while effects active - won't impact server performance during raids
• Framework Flexible - Works with ESX, QBCore, or standalone with provided integration examples

Perfect For

• Police/SWAT Operations - Entry teams can properly breach with tactical support instead of just rushing doors
• Whitelisted RP Servers - Adds realism to warrant executions and high-risk arrests
• Gang War Servers - Creates tactical depth in base raids and territory conflicts
• Competitive PvP - Skill-based utility that rewards positioning and timing over pure aim
• Military RP - Essential for special forces, counter-terrorism, or tactical training scenarios

Configuration Options

The script includes a separate config file where you can fine-tune every aspect of flashbang behavior:

• Weapon Label: Customize the in-game display name
• Time to Explosion: Adjust fuse duration (realistic timing vs gameplay balance)
• Voice Chat Toggle: Enable/disable voice muting during stun (works with mumble-voip and pma-voice)
• Effect Duration: Control how long players are blinded and disoriented
• Sound Volume: Adjust detonation audio level to match your server's audio design
• Effective Range: Set the radius where flashbangs impact players (proximity matters)

QBCore Integration Guide

For QBCore servers, follow these exact steps to integrate the flashbang weapon:

Step 1: Add Weapon Definition (qb-core/shared/weapons.lua)

Insert this line in your weapons table:

['weapon_flashbang'] = {['name'] = 'weapon_flashbang', ['label'] = 'Flashbang', ['ammotype'] = nil, ['damagereason'] = 'Bombed / Exploded / Detonated / Blew up'},

Step 2: Add Item Definition (qb-core/shared/items.lua)

Insert this item entry:

['weapon_flashbang'] = {['name'] = 'weapon_flashbang', ['label'] = 'Flashbang', ['weight'] = 1000, ['type'] = 'weapon', ['ammotype'] = nil, ['image'] = 'weapon_flashbang.png', ['unique'] = true, ['useable'] = false, ['description'] = 'A tactical stun grenade used by law enforcement'},

Step 3: Add Removal Logic (qb-weapons/client/main.lua)

Inside lines 180-181, add:

elseif QBCore.Shared.Weapons[weapon][name] == weapon_flashbang then
TriggerServerEvent('QBCore:Server:RemoveItem', weapon_flashbang, 1)

Step 4: Update Inventory Check (qb-inventory/client/main.lua)

Replace line 449 with:

elseif weaponName == weapon_stickybomb or weaponName == weapon_pipebomb or weaponName == weapon_smokegrenade or weaponName == weapon_flare or weaponName == weapon_proxmine or weaponName == weapon_ball or weaponName == weapon_molotov or weaponName == weapon_grenade or weaponName == weapon_flashbang or weaponName == weapon_bzgas then

Technical Details

Performance: Extremely lightweight - 0.1ms idle, peaks at 0.05ms during active effects

Voice Integration: Compatible with mumble-voip and pma-voice for realistic communication disruption

Framework Support: ESX (native), QBCore (full integration guide included), Standalone (with manual weapon setup)

Dependencies: None beyond your chosen voice system (if using voice chat disabling feature)

Tactical Applications

Police Breaching: SWAT teams can properly execute dynamic entries - throw flashbang through door, breach while suspects are stunned and can't coordinate via voice

Building Clearance: Room-by-room tactical clearing becomes viable - toss flashbang, enter during effect window, secure before recovery

Hostage Rescue: Rescue teams can stun hostage-takers without lethal force, creating opportunities for safe extractions

Defensive Deterrent: Property owners can deploy flashbangs to repel raiders, buying time to reposition or call for backup

Convoy Ambushes: Criminals can use flashbangs to disable security escorts during transport heists

Balancing Considerations

On roleplay servers, you might want longer effect durations (8-12 seconds) to reward tactical planning and coordination. On competitive PvP servers, shorter durations (3-5 seconds) prevent frustrating downtime while still creating tactical opportunities. The voice chat disable is powerful on RP servers where communication is everything, but might feel excessive on casual servers - test and adjust based on your community feedback.

What Makes It Stand Out

Most grenade scripts are just visual effects with damage. This actually changes gameplay - the vision impairment forces affected players to disengage, the voice chat integration breaks coordinated defense, and the configurable parameters let you dial in exactly how powerful you want flashbangs to be. It's the difference between cosmetic cool factor and genuine tactical utility that shifts how your server handles raids, arrests, and combat engagements.
