the following code is about freezing the first zombie, but its for zp 5.0 so can anyone edit this and make it work for zp 4.3

#include <amxmodx>
#include <fun>
#include <zp50_core>

#define PLUGIN     "[ZP50] Freeze first zombie"
#define VERSION             "1.0"
#define AUTHOR             "wicho"

#define MarkPlayerSpeed(%0)  bitPlayerSpeed |= (1 << (%0 & 31))
#define ClearPlayerSpeed(%0) bitPlayerSpeed &= ~(1 << (%0 & 31))
#define IsPlayerSpeed(%0)    bitPlayerSpeed & (1 << (%0 & 31))

new bitPlayerSpeed

new cvar_time

public plugin_init() 
{ 
    register_plugin(PLUGIN, VERSION, AUTHOR) 
        
    cvar_time = register_cvar("zp_freeze_frist_zombie", "5.0")
} 

public zp_fw_core_infect_post(id) 
{     
      if(is_user_alive(id) && zp_core_is_first_zombie(id))
      {
         IsPlayerSpeed(id) = get_user_maxspeed(id)
         set_user_maxspeed(id, 1.0)
         set_task(cvar_time, "Unfreeze", id)   
      }    
}      

public Unfreeze(id) 
{
   set_user_maxspeed(id, IsPlayerSpeed(id))
}
