Re: Client index 0 is invalid

You're passing 0 to GetClientTeam, which is not a valid client index.

Then you didn't fix it.

Stop calling GetClientTeam() if client == 0.

Re: Client index 0 is invalid

It is from a take damage hook (by the error message).
From what I have gathered, this generally happens if you are running a listen-server SourceMod, where the host is client 0, but the actual player entity is at 1. You could change it to:

Code:

if(test)

{

        if (client == 0)

        {

                if (IsValidEntity(client+1)) client++;

                else return Plugin_Continue;

        }

        if(GetClientTeam(client) == 2)

        {

                if(GetClientTeam(attacker) == GetClientTeam(client) && IsFreezed[client] && !IsFreezed[attacker])

                {

                        SetEntityMoveType(client, MOVETYPE_WALK);

                        SetEntPropFloat(client, Prop_Data, "m_flLaggedMovementValue", 1.0);

                        SetEntityRenderColor(client, 255, 255, 255, 255);

                        IsFreezed[client] = false;

                        --FreezeCount;

                } 

                else if(GetClientTeam(attacker) != GetClientTeam(client) && !IsFreezed[client])

                {

                        SetEntityMoveType(client, MOVETYPE_NONE);

                        SetEntPropFloat(client, Prop_Data, "m_flLaggedMovementValue", 0.0);

                        SetEntityRenderColor(client, 0, 0, 255, 255);

                        IsFreezed[client] = true;

                        ++FreezeCount;

                }

        }

}

Also, I haven't seen the ++ or -- before the variable before, but I suppose if it works, then ok.

Re: Client index 0 is invalid

The servers entity index is 0 on a listen server. The clients entity index is 1. Clients start from 1.

Re: Client index 0 is invalid

The attacker and inflictor parameters can be 0 for e.g. fall damage.

Re: Client index 0 is invalid

As Peace-Maker said, entity can be 0, which means "world" (fall damage, prop damage), glad you solved.
