Hi @bluemagic123, I think I've found a bug, but I'm not sure. I was using the globalNPC hook CanBeHitByProjectile, and found that it wasn't being called in the way I'd expect. It sounds like it should only be called when a projectile hits a NPC, but when I used it, it was being called every frame. I just thought I'd see what's up with that. Thanks.

Edit: Also, is there a way to add a custom field to each vanilla NPC? I tried putting one in globalNPC, but there's only one instance of that for all NPCs.

You have to use NPCInfo for that (on the tML wiki it's called "EntityInfo").

ExampleMod have all example ^^'. I have use ExampleMod, and my town NPC is 100% functionnal.

For the ennemy, go look examplemod, it have many example after, you need just check if this is a world on hardmode or not.

It looks like the CanHit checks occur before the collision checks for projectiles against NPCs.
