How to count AI soldiers kills?

[lato1982 36]

Hi,

I'm trying to count kills for each soldier of my squad. I want to increase my AI soldiers skills dependend on number of their kills. I have a fixed number of AI soldiers in my squad, each one has an identity.

I know I have to use addEventHandler "killed" for all enemy soldiers, but not sure how to use the information about the killer name, to change a variable like ai01_kills_number?

the callback used in the killed eventhandler will give you an array with the killer and the killed unit as a parameter.

friendlyAIUnits = units (group player);
killedEH = {
   _killed = _this select 0;
   _killer = _this select 1;

   _numKills = (_killer getVariable ["killsNum", 0]) + 1;    
   _killer setVariable ["killsNum", _numKills, true];

   if (_killer in friendlyAIUnits) then
   {
       // the killer is one of your AI members, do whatever you feel fancy here
       // preferably calling another function to add skill points or whatever.
   };
};



{
   if (!(isPlayer _x) && !(_x in friendlyAIUnits) ) then
   {
       _x addEventHandler ["killed", killedEH];
   };
} forEach allUnits;

using the above code will ensure that no matter who kills AI players, they'll get their kill counter increased.

So using something like

_numKilly = theUnit getVariable ["killsNum", 0];

on any AI or human unit in your game will get the corresponding kill counter.

Thanks a lot, I'll try this out!

I can't figure out why the code above works well, but this won't:

killedEH = {
   _killed = _this select 0;
   _killer = _this select 1;

   _numKills = (_killer getVariable ["killsNum", 0]) + 1;    
   _killer setVariable ["killsNum", _numKills, true];
_killer setSkill ((skill _killer) + 0.01);

   if (_killer in friendlyAIUnits) then
   {

// hint str _numKills;

   };
};

soldier1 addEventHandler ["killed", killedEH];

changing last lines to this and all works again, why?:

friendlyAIUnits = units (group player);

{
   if (!(isPlayer _x) && !(_x in friendlyAIUnits) ) then
   {
       _x addEventHandler ["killed", killedEH];
   };
} forEach allUnits;  

I want to add this event handler to specific soldiers, but cannot somehow. Any ideas?

The forEach-Loop causes that everyone except of your soldiers will count towards the kill counter, hence the query if _x is not in friendlyAIUnits.

What you actually do is limiting the counter to soldier1, so if soldier1 dies, the one killing him will get his counter upped.

If soldier1 is someone in your team, this would have the opposite effect of the one you wanted to have.

I guess you want to adjust who actually can increase his kill counter, am I right? If that's the case, you have to change the if-clause in the eventhandler to make sure that the _killer is (for example) soldier1.
