[ZP] How to enable friendly fire in ZP5.0

I have tested it and it is working.

Just open your zp50_gamemodes.sma.

Then, replace this code in fw_TraceAttack and fw_TakeDamage:

   // Prevent attacks when no game mode is active
   if (g_CurrentGameMode == ZP_NO_GAME_MODE)
       return HAM_SUPERCEDE;
   
   // Prevent friendly fire
   if (zp_core_is_zombie(attacker) == zp_core_is_zombie(victim))
       return HAM_SUPERCEDE;
--->

   // Prevent attacks when no game mode is active
   if (g_CurrentGameMode == ZP_NO_GAME_MODE)
       return HAM_IGNORED;
   
   // Prevent friendly fire
   if (zp_core_is_zombie(attacker) == zp_core_is_zombie(victim))
       return HAM_IGNORED;
Lastly, just enable friendly fire (mp_friendlyfire 1).

Reminder:

Yet, this is not good for a ZP gameplay.
