Description:

These are 4 upgrades any client can manually enable/disable at any time:

- Laser Sight
- Night Vision
- Silencer (L4D1 only)
- Fast Reload (L4D1 only)

All upgrades are made permanently per-client, not per-weapon (and saved to cookies, loaded on client re-join).

Why one more plugin?
- Most plugins for laser in L4D1 cause clients to crash on some servers. This fork uses SDK-method that works fine all the time.

Restrictions:
- for L4D2 only Laser & Night Vision are available at the moment.
- for L4D2 it is impossible to remove crosshair due to the protected client-side command "crosshair 0". I also tried to change the different hud properties of the client, but they don't have the desired effect.

Specific:
- Plugin is blocking perk sound automatically when you equip the upgrade.
- atm, plugin cannot block the secondary sound (in L4D2) and game hint (on-screen message and sound) (L4D2) when you equip/re-equip weapon with upgrade. Need help.

Commands:

sm_laser - Toggle Laser Sight
sm_laseron - Turn on the laser
sm_laseroff - Turn off the laser
sm_night - Toggle Night Vision
sm_silent - Toggle Silencer (L4D1 only)
sm_silencer - same
sm_reload - Toggle Fast Reload (L4D1 only)

Plugin is rewritten on the basis of my alternative fork branch.

1.4 (01-Mar-2019) - Converted to a new syntax and methodmaps - Added sdk method to enable laser - Added more reliable managing the cookies - Added "l4d_useful_upgrades" config file. - Added "l4d_force_silencer" ConVar to force Silencer Upgrade on spawn - Added "l4d_force_laser_sight" ConVar to force Laser Sight Upgrade on spawn - Added "l4d_force_night_vision" ConVar to force Night Vision Upgrade on spawn - Added "l4d_force_fast_reload" ConVar to force Fast Reload Upgrade on spawn - Added checking for game requirements (L4D1 only). 1.3 (private) - Removed laser, because it crash my server 1.2 (based on alternate fork branch) - Added saving upgrades state to the cookies - Added some safe checkings

I could create a plugin that uses the night vision but it can be used to decorate an event such as a car alarm or a horde or a spawn tank, activated only when an event happens, or with a timer. would create a good atmosphere

[Dragokas]

Is it a question?
Look how it is done in "Mutant zombies" plugin.

[Dragokas]

1.5 (07-Mar-2019)
Added additional delay before activation the laser because sometimes player's netprops have no time to init.

[Dragokas]

Anybody know, why that crash can happen? https://forums.alliedmods.net/showthread.php?t=315101

[Alexmy]

Why do you check real players?

PHP Code:

public Action round_end(Event event, const char[] name, bool dontBroadcast)
{
    for(int i=1; i<=MaxClients; i++)
    {
        if(IsClientInGame(i) && !IsFakeClient(i)) DisableAllUpgrades(i);
    }
} 


Only need a check on the game and everything.Further did not begin to look.

Bots doesn't need upgrades.

What if someone uses upgrade and disconnects/AFK.. the bot carries the upgrades or not?

[Dragokas]

Actually, I missed that. I even didn't think about that. Possibly, bot cares the upgrade. I have to check.
Thanks, SilverShot and Alexmy.
