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").

Are the tML servers strained?

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.
The internal name and npc.name need to be the same.
Good idea, but it's not like we have much time for that.Suggestion: Mod of the week thread/section, so the little guys get featured. Make sure to explain why you chose it.

ok, i did some more testing and i found out that magic weapons wont cause this effect. anyone got an idea why this happens??
[doublepost=1468111049,1468110898][/doublepost]here is the new code:
[doublepost=1468111207][/doublepost]and how do i make him display dust without being hit, just by itself (like the Skeleton Mages, they have these cool particle things on them)
