WoWPlayer one = new WoWPlayer(); WoWPlayer two = new WoWPlayer(); // Get distance between 2 objects float distance = one.Position.DistanceTo(two.Position); If you are looking for party stuff take a look at "wManager.Wow.Helpers.Party"
Hope i understood the question right ?
Do you want to be able to check if the whole group is near or just one of them?

Hm could be a reason. Replace it with
ObjectManager.GetObjectWoWUnit().Count(u => u.Skinnable && u.GetDistance2D <= 40); If you just want dead units that are skinnable you need to add "&& u.IsDead"
Hope that helps

I would recommend to put all the validations into a method.
Another way would be to use @Droidz inbuild engine.

Have fun.

PS: If a method is missing just call me, I just copied it right out of my framework.

BTW: It is used for WOTLK and I'm not sure if there where changes in the lua commands. But at the end it should give you an idea how it could be done. There are allways multi ways to reach the goal.

It depend at what kind ID you want to use. If you want to use the mob id this could be something for you.
 
ObjectManager.GetWoWGameObjectByyId(1234).FirstOrDefault()?.GetDistance < 75  

// Get target you want to WoWUnit target = any target you want // Target the target Interact.InteractGameObject(target.GetBaseAddress, !ObjectManager.Me.GetMove); This would be one way how you target something.

Get player object by name:
WoWPlayer player = ObjectManager.GetObjectWoWPlayer().Where(p => p.IsValid && p.Name == "PlayerName").FirstOrDefault();  
Target player:
Interact.InteractGameObject(player.GetBaseAddress, true); Cast spell at the specified target:
string targetName = "blubb"; int spellID = 999; Lua.LuaDoString($"CastSpellByID({spellID}, \"{targetName}\")");  
Hope it helps.

Well i will answer my self. Restart the game and the bot and you should be fine.
Thanks goes to betterSister for the tipp.

var tank = getTanks(); WoWUnit target = ; Interact.InteractGameObject(target.GetBaseAddress); _wrath.Launch(); Thats why i said don't use var ^_-
// Get all available tanks List<WoWPlayer> tankList = getTanks(); // Get the first tank in the list WoWPlayer tank = tankList.First(); // Get the target of the tank WoWUnit target = tank.TargetObject; // Focus at target Interact.InteractGameObject(target.GetBaseAddress, true); // Use the skill _wrath.Launch(); It is way essiert to read ^_-
