old version code:
PHP Code:
CreteSurvivorBot()
{
int bot = CreateFakeClient("fake");
ChangeClientTeam(bot, 2);
KickClient(bot);
//the bot index is invalid. because bot was disconnected.
//we can't write code, like that:
if(!IsPlayerAlive(bot))
{
//this is mistake, can't exec here
//ba la ba la ...
}
}
public Action:OnClientPutInServer(int _iClientIndex)
{
//We need judgment this bot was created by we are
//write code
// ba la ba la ...
}
now. using my extensions.
PHP Code:
#include <CreateSurvivorBot>
int Test()
{
int index = CreateSurvivorBot();
if(IsValidEntity(index))
{
PrintToServer("Created SurvivorBot:%d", index);
//ba la ba la ... write code
return index;
}
return -1;

Update 12/18/2020
For Windows:
Signature of NextBotCreatePlayerBot<SurvivorBot> changed.
The CreateSurvivorBot.ext.2.l4d2.dll changed.
The signature in the next version should not change. The premise is CDirector::AddSurvivorBot() function will not be modified by valve.
