After dropping our CS:GO server months ago, we decided to move back to it. We have been trying to find a fix/workaround that lets us have a decent knockback for CS:GO. The workaround isn't equal to what you'd be expecting if you had only played CS:S' zombie mods, but it is enough to be enjoyable. It is based (we cooperated with mappers to get it) on setting the basevelocity field when hit, which lets you have a subtle knockback/push while on the ground (it lets a player hold a zombie by himself alone, which is enough for us). As seen on CS:GO, you'll get a normal knockback while on the air.

To handle this and make it more enjoyable, we figured out we could depend on subtle ground knockback plus extra vertical knockback (to produce 'jumps') provided by some weapons. We are publishing our vertical knockback for grenades too in case anyone wants a similar system. On the server, we have extended it for a few other weapons (knives, for example, and the awp). We thought about forcing a vertical knockback if on the ground (as you can see on the code), but we found that to be annoying (despite other communities using it).
Code:
#include <sourcemod>
#include <sdktools>
#include <sdkhooks>
#pragma semicolon 1
new Handle:g_Cvar_MaxZKnock = INVALID_HANDLE;
new Handle:g_Cvar_HeKnock = INVALID_HANDLE;
public Plugin:myinfo ={
name = "Z:R Grenade Boost",
author = "Marica Stevens",
description = "Pushes zombies upwards when hit by a grenade.",

};
public OnPluginStart()
{
g_Cvar_MaxZKnock = CreateConVar("sm_max_zknock", "32.0", "Knock in Z");
g_Cvar_HeKnock = CreateConVar("sm_he_knock", "320.0", "Max Knock in Z");
HookEvent("player_hurt", Event_HandleNadeDamage);
}
public OnPluginEnd()
{
UnhookEvent("player_hurt", Event_HandleNadeDamage);
}
public Event_HandleNadeDamage(Handle:event, const String:name[], bool:dontBroadcast)
{
new clientid = GetEventInt(event, "userid");
new client = GetClientOfUserId(clientid);
new damage = GetEventInt(event,"dmg_health");
decl String:weapon[32];
GetEventString(event, "weapon", weapon, sizeof(weapon));
if(GetClientTeam(client)==2 && StrEqual("hegrenade", weapon))
{
new Float:vector[3];
vector[0] = 0.0;
vector[1] = 0.0;
vector[2] = GetConVarFloat(g_Cvar_HeKnock)*damage;
if(vector[2]> GetConVarFloat(g_Cvar_MaxZKnock))
{

}
new g_iBaseVelocityOffset = FindSendPropOffs("CBasePlayer","m_vecBaseVelocity");
SetEntDataVector(client, g_iBaseVelocityOffset, vector, true);
}
}
Finally, to address the problem with zombies spawning as classes, we've tried to perfect the 'fix' (which didn't feel like enough to us) that Franc1sco made. We're sure that he
probably updated his own, but seeing how it wasn't updated we're publishing ours.
Code:
#include <sourcemod>
#include <sdktools>
#undef REQUIRE_PLUGIN
#include <zombiereloaded>
new zombie1, zombie2, zombie3;
public Plugin:myinfo =
{
name = "ZR Class Fix",
author = "Mapeadores",
description = "Class Fix (Franug plugin modification)",
version = "1.5",
url = "http://Mapeadores.com/"
};
public OnPluginStart()
{
//Edit this with your zombie classes
zombie1 = ZR_GetClassByName("Clasico");
zombie2 = ZR_GetClassByName("Zombie Rapido");
zombie3 = ZR_GetClassByName("Zombie Resistente");
}
public ZR_OnClientInfected(client, attacker, bool:motherInfect, bool:respawnOverride, bool:respawn)
{
new vida = GetClientHealth(client);
if(vida < 300)
{
CreateTimer(0.5, TimerAsegurarClase, client, TIMER_FLAG_NO_MAPCHANGE);
}
}
public Action:TimerAsegurarClase(Handle:timer, any:client)
{
AsegurarClaseDefault(client);
}
public AsegurarClaseDefault(client)
{
SetEntityHealth(client, 5000);
new randomnum = GetRandomInt(0, 2);
switch(randomnum)
{
case 0:
{
SetEntityModel(client, "models/player/mapeadores/morell/zh/zh3fix.mdl");
ZR_SelectClientClass(client, zombie3, true, true);
}
case 1:
{
SetEntityModel(client, "models/player/mapeadores/kaem/zh/zh1fix.mdl");
ZR_SelectClientClass(client, zombie1, true, true);
}
case 2:
{
SetEntityModel(client, "models/player/mapeadores/kaem/zh/zh2fix.mdl");
ZR_SelectClientClass(client, zombie2, true, true);
}
}
}
This plugin is a sample from our server. If you have seen Franc1sco's plugin you'll notice that it hasn't changed much, the only difference is that the plugin selects a valid class for a player so that this round (if possible) or next he gets a real zombie class. You'd need to adjust it to your settings by adding more classes following the style (we thought of making a nicer plugin but ended up slacking, sorry about that).
Those plugins, fixes and workarounds aren't optimal, probably, but seeing how the community doesn't seem to help, we thought that by adding our little grain of sand perhaps others will eventually join us and help the mod develop as a whole with interests aside.
On a different matter, some mappers have been porting maps with us being the test subjects. The mappers will eventually publish their ports in some sort of way, as they're following a set of porting rules to ensure that the ports have a minimal filesize while adapting the looks of the maps to the new engine. We have seen that some communities (shockingly, those that seem to rarely contribute or, rather, try to mock others whilst saying they've addressed issues) have 'stolen' those maps while they are still in the process of being perfected (and some even said they ported the maps themselves, which is rather bothersome). We'd value that, for some time, you stepped out and didn't use '_p' map ports until we have a big enough batch for everybody to use.
