Perhaps, in order for some abilities to work, you still need to change the player model ( in particular, for the tank's ability )

PHP Code:

#pragma semicolon 1
#pragma newdecls required

#include <sourcemod>
#include <sdktools>

#define VIRTUAL 205 /* 206 is for linux */

public void OnPluginStart()
{
    RegConsoleCmd ("awd", awd);
}

public Action awd (int a1, int a2)
{
    int ability = Ability (a1, "ability_charge");
}

int Ability (int client, const char[] name)
{
    int entity = CreateEntityByName(name);
    DispatchSpawn(entity);
    
    static Handle hCall;
    
    if ( !hCall )
    {
        StartPrepSDKCall(SDKCall_Entity);
        PrepSDKCall_AddParameter(SDKType_CBasePlayer, SDKPass_Pointer);
        PrepSDKCall_SetAddress (view_as<Address>(LoadFromAddress(view_as<Address>(LoadFromAddress(GetEntityAddress(entity), NumberType_Int32) + VIRTUAL * 4), NumberType_Int32)));
        hCall = EndPrepSDKCall();
    }
    
    SetEntPropEnt(client, Prop_Send, "m_customAbility", entity);
    
    SDKCall(hCall, entity, client);
    
    return entity;
}
