Weapon Jam

Introduction:
While shooting, your weapon might get jammed and you need to reload. This way you can balance guns or making shootouts more random. You can modify the probability for each weapon (by default they are all 10). Shotguns are not included because I thought that it would be a silly idea.

Probabilities:
1 = 0.01% (= an average of one in a ten thousand bullet causes weapon to jam)
2 = 0.02%
3 = 0.03%
...
10 = 0.1% (= an average of one in a thousand bullet causes weapon to jam)
...
100 = 1%
...
1000 = 10%

Installation:
- Upload .smx to addons/sourcemod/plugins folder.
- Upload .sp to addons/sourcemod/scripting folder.
- Configs file will be created automatically when plugin is used for the first time.
- If you want to have a version with colored chat, download the .zip > Unzip > Upload. Folders should be right.

Credits:
DorCoMaNdO - Thank you for helping me with the code.

Changelog:
1.10 - Auto-create configs file, new cvar which let's you to decide about plugin messages, improvements to code, increased the range of probability.

I haven't really had any good recording software. But I'll give it a try.

Please!

Instead of defining the "gun" variable for every weapon, you can use

new gun = GetEntPropEnt(client, Prop_Send, "m_hActiveWeapon");

above everything, same applies for the other variables, also you can place the comparison of the jam variables at the top and change them for each weapon as you need, then call the jam at the bottom.
Also there's no need of the ammo variables, and no need for adding the randomnum variable to the messages, you seemed to describe the convars as integers, but use them as floats in the code, use GetConVarInt instead.
Another thing is that you used both spaces and tabs at the beginning of lines, pick one and use it, I recommend tabs. Switching from spaces to tabs and vice versa will throw a warning when compiling.
You should have something like that at the end :

public Action:Event_WeaponFired(Handle:event, const String:name[], bool:dontBroadcast)
{
	if (!GetConVarBool(Enabled))
	{
		return;
	}
	
	new client = GetClientOfUserId(GetEventInt(event, "userid"));
	new String:sWeaponName[64];
	GetClientWeapon(client, sWeaponName, sizeof(sWeaponName));
	new gun = GetEntPropEnt(client, Prop_Send, "m_hActiveWeapon");
	new Float:x = 1.0;
	new randomnum = GetRandomInt(0, 999);
	if(StrEqual(sWeaponName, "weapon_glock"))
	{
		x = GetConVarFloat(Probability_glock);
	}else if(StrEqual(sWeaponName, "weapon_hkp2000"))
	{
		x = GetConVarInt(Probability_hkp2000);
	}
	// Other weapons here
	
	x += 499;
	if(randomnum > 499 && randomnum <= x)
	{
		SetEntProp(gun, Prop_Send, "m_iClip1", 0, 1);
		PrintToChat(client, "\x04[SM] \x01Weapon jammed!");
	}
}

Haven't attempted to compile this, but it should work.

Thanks for your advice! I'll try it. "x = GetConVarInt(Probability_hkp2000)" Don't you mean x = GetConVarFloat(Probability_hkp2000)?

Has anyone any idea why console gives me:
"sm_weaponjam_chat" = "1" min. 0.000000 max. 1.000000 - Who can see when your weapon gets jammed. 0 = nobody, 1 = you (chat), 2 = all, 3

I compiled it at first when that cvar had max value 1 but then I noticed that problem but it wont change in console no matter what I try...

Nope I meant Int, also change the definition of x as a float, define it as int.

Again you could use GetConVarInt instead of float, you add an extra space at the beginning of the message the player(s) receive(s).
You could also use %N instead of %s for the player's name, providing the client instead of a string, like so :

PrintToChat(client, "Your name is %N", client);

Another thing you might want to do is use "switch" instead of "if", at least on the message part, like so :

switch(GetConVarInt(PrintWho))
{
	case 1:
		PrintToChat(client, "\x04[SM] \x01Weapon jammed, reload!");
	case 2:
		PrintToChatAll("\x04[SM]%N: \x01My weapon got jammed! I need to reload!", client);
	case 3:
		PrintCenterText(client, "[SM] Weapon jammed, reload!");
}

You might also want to add (or replace "All" with) a "Team" option for the message convar.

About your issue, if you look at the convar through the generated config, delete the config and let it regenerate. Configs aren't updated when you change something in the convar's definition.

Thank you again! I'll make those changes and upload a new version.

"Again you could use GetConVarInt instead of float, you add an extra space at the beginning of the message the player(s) receive(s).!"
I have to add that extra space or colours won't work in chat. I can add second file without colors.

"You might also want to add (or replace "All" with) a "Team" option for the message convar."
I need to study more about how to print to team. Looks like simple PrintToChatTeam isn't automatically defined.
