When it says [GARBAGE COLLECT], that means it was probably a coincidence that a garbage collection happened while the hook was being called, so it's not the fault of the plugin. If you see these messages often, that is because the CanBeTargeted hook is called so often that it's more likely to be running at the time of a garbage collection than other hooks.

That being said, it is possible for some hooks to be more likely to actually trigger a garbage collection, especially if the plugin is allocating memory during the hook call. Looking at the implementation of the CanBeTargeted hook in True PVE, I do see some obvious garbage allocations.

• A new array is created to call the CanEntityBeTargeted hook.
• Every time the hook returns false, that value is being boxed as an object.
• When the plugin calls its internal CheckExclusion method, it uses LINQ which is creating some garbage objects.

thanks, so.. i will waiting for refactoring and must not to do something with it?

I can't say whether it's appropriate to the plugin on your server in it's current state. Up to you, depending on whether this issue is causing problems that players notice, and depends on how critical this plugin is for the experience you are trying to provide. 

You will have to talk to nivex about the above suggested performance improvements. Unclear if he has seen this thread or plans on making those changes. I would contribute a patch but I'm too busy with many other plugins.

thank you for your time, I'm waiting for nivex to find time for this forum, I have questions in other plugins too:)

the only solution is to remove the hook (and LINQ because it's so terrible in its currently implemented version). implementing your suggestions would help some but would not fix the issue (lets not forget that OnNpcTarget(BasePlayer player, HTNPlayer npc) in the past) because of how often its called

i've already removed this hook and the linq in the next update but i haven't gotten around to finishing the update. though i believe it works fine if you want to try it.

• Updated default configuration to include snowmobiles entity group (snowmobile, tomahasnowmobile) with rule `nothing can hurt snowmobiles`
• Updated default configuration to separate bradley entity group (BradleyAPC, maincannonshell and exclude BasePlayer) from the npcs entity group with rule `bradley cannot hurt anything` (exclusion allows BasePlayer to take damage)
• Updated TwigDamage to take damage from any source instead of players only
• Allowed damage from all `assets/bundled/prefabs/modding/volumes_and_triggers/hurt/` map prefab triggers
• Blocked MLRS rocket damage when initiator is lost
• Blocked arrow, blunt, generic and heat damage when inititator is lost
• Removed SamSitesIgnorePlayers and added PlayerSamSitesIgnorePlayers and StaticSamSitesIgnorePlayers retroactively
• Updated OnSamSiteTarget to return true as it's a non-bool hook
• Removed LINQ

Not sure why I was directed to post in this thread, but the turrets not targeting players was fixed. It was a misconfiguration in the config. 

because if it were a bug in the current version then it would have most likely been fixed in the update. no sense in me trying to chase the rabbit without trying to bury it in the hole to start with.
