Ways to hook final trigger_hurt

[Raheem]

Hello,

Here i'm going to speak a little about trigger_hurt and how to catch it when it happens at end of the map, we are speaking about the final trigger_hurt that should kill all players except who escaped.

First let's take a general overview how zombie escape map works?

• There is many scenarios like:
  
  First you press a button and then the targeted func_tracktrain or func_vehicle comes through the path_track then players enter inside the moving entity and they travels till players touch a regoin that defined as trigger_multiple and when this trigger_multiple is touched it will activate the trigger_hurt.
  
  Another idea is that the trigger_hurt is called by a button not trigger_multiple. Like after player go to safe zone they press a button and the trigger_hurt then activated through this button.

So to hook trigger_hurt, you will need to hook when player touching trigger_multiple or when player press the button that should activate the trigger_hurt.

Another idea is to check if any player touched a trigger_hurt with high damage, this means it's the final trigger_hurt.

So let's discuss possible ways:

1. Touching trigger_hurt with High Damage:

• Code: [Select all] [Expand/Collapse]

  1. #include <zombie_escape>
  2.  
  3. #define MIN_DAMAGE 9000
  4.  
  5. // Variables
  6. new bool:g_bCalledTrigger, g_iTriggerHurtForward
  7.  
  8. public plugin_init()
  9. {
  10.     register_plugin("trigger_hurt Listener", "1.0", "Raheem")
  11.    
  12.     // Here we register touching any trigger_hurt
  13.     RegisterHam(Ham_Touch, "trigger_hurt", "Fw_TouchTrigger_Post", 1)
  14.    
  15.     g_iTriggerHurtForward = CreateMultiForward("trigger_hurt", ET_IGNORE)
  16. }
  17.  
  18. public ze_game_started()
  19. {
  20.     g_bCalledTrigger = false
  21. }
  22.  
  23. public Fw_TouchTrigger_Post(iEnt, id)
  24. {
  25.     if(!is_user_alive(id) || !pev_valid(iEnt))
  26.         return HAM_IGNORED
  27.    
  28.     if (pev(iEnt, pev_dmg) > MIN_DAMAGE)
  29.     {
  30.         if (!g_bCalled)
  31.         {
  32.             ExecuteForward(g_iTriggerHurtForward)
  33.             g_bCalled = true
  34.         }
  35.     }
  36.  
  37.     return HAM_IGNORED
  38. }

Forward Test:

• Code: [Select all] [Expand/Collapse]

  1. #include <zombie_escape>
  2.  
  3. forward trigger_hurt();
  4.  
  5. public plugin_init()
  6. {
  7.     register_plugin("trigger_hurt Listener Test", "1.0", "Raheem")
  8. }
  9.  
  10. public trigger_hurt()
  11. {
  12.     ze_colored_print(0, "Final Damage Triggered!")
  13. }

2. If player touching trigger_multiple and touching the moving entity:

• Code: [Select all] [Expand/Collapse]

  1. /*
  2. *   This will hook the trigger_hurt when it's activated.
  3. *   What i know is that trigger_hurt can be activated via button or trigger_multiple
  4. *   This method is good for maps that conatin trains..etc
  5. *   Also we will hook which using trigger_multiple only
  6. *
  7. *   If user is touching the train and this player touched trigger_multiple then the trigger_hurt will be called.
  8. *   In fact the trigger_hurt will be called once trigger_multiple is touched by player but we will tie it with train also. Away to avoid hardcode every map.

3. If trigger_hurt is activated via button then hook this button and when someone press it.

4. We can combine the 1, 2 in one plugin, to make somehow general idea:

• Code: [Select all] [Expand/Collapse]

  1. /*
  2. *   This will hook the trigger_hurt when it's activated.
  3. *   What i know is that trigger_hurt can be activated via button or trigger_multiple
  4. *   This method is good for maps that conatin trains..etc
  5. *   Also we will hook which using trigger_multiple only
  6. *
  7. *   If user is touching the train and this player touched trigger_multiple then the trigger_hurt will be called.
  8. *   In fact the trigger_hurt will be called once trigger_multiple is touched by player but we will tie it with train also. Away to avoid hardcode every map.

This is all ways how to detect the end round trigger_hurt that should kill all players that touching it or it's zone.
The final combined code is a very good approach to hook this event, it's success can be 95% so it looks nice to be used.

Why i need to listen to this event?

• Maybe it's useful in some cases. and you maybe need to make somethings when it's called or after it's called.
  Basacilly i thought in this because i was trying to write a code that if some zombies not died with this trigger_hurt at the round end then i'll give them a chance 20 seconds to try if they failed i'll slay them. I must know how to hook the final trigger_hurt in order we can give him the chance and do all our code.

That's all i know for now, hope it help you
