Grim Trap Targeting Issues #1729

Closed ashinckley closed 3 months ago

ashinckley commented 3 months ago

There was a grim trap room in the distance in the demon halls. I positioned myself far in the distance and allowed my prismatic image occupy several mobs between me and the grim trap room. There was a clear line-of-fire between the mobs and grim trap, however the distance was so great that I could no longer see the mobs or prismatic image. I fired off a wand of blast wave, and I was targeted by the grim traps which fully utilized my ankh. I assumed all the mobs were killed if I had been targeted, but when I approached, the mobs and prismatic image were still between me and the grim traps. I took a few steps back, making sure there was a clear line of fire between the mobs and remaining grim trap and tried again by throwing an item at a selected trap. This time I was instantly killed. The bolt went right between the mobs and prismatic image (unseen from my field of view). Perhaps there's a bug where grim traps only target characters that are visible to the hero?

It's a bit hard to be sure about this without seeing the environment your describing.

Grim traps do respect line of sight rules, so if something blocks the grim trap from attacking a certain target (e.g. the corner of a wall) then it would shoot at a farther target which it does have a clear path to.

I do think it would be fair to give traps like this a max range either way though, they aren't intended to be able to hit things at great distances.

Closing this as there was no reply, feel free to comment again and I'll re-open.

I will add giving these traps a max range to my to-do list regardless though, I think that's a sensible change to make.
