Calculation log question

[Joshua]

What does it mean when the calculation log lists a hit with no damage? I've wondered before and it's not obvious to me how this could happen, though I've noticed it doesn't report damage done when targeting a wall.

See e.g. from the attached screenshot:

Adv. Beam Cannon (65%) Hit

(I fired it at a watcher.)

The calc log is admittedly not always 100% accurate or clear--we've had this come up before in a number of forum threads (things like showing wall hits are in the Ideas board, for example, and multishot weapon hit display values were reported as a bug). That log's contents have never been worked on since the 7DRL version (when it was first added by request), mainly because the truly important combat info is present on the map. I've wanted to revisit it and it's been on the list for years now, but it's been low priority because it's a rather large project compared to the small gains in usability--adding certain features would require a redesign.

Actually, more or less your same question was posed in 2015

I currently have a lot of notes gathered for a potential future calculations log update, but it's currently held in the "bigger features" category, which is stuff that has no timeline but I really would like to get to some day. It's become a fairly large pool of semi-important features...

I did try searching before posting but apparently should have tried "combat log" instead of "calculation log" . Thanks for the explanation.

Heh yeah I call it the calc log myself (since the original purpose behind adding it was to show how hit chance was calculated), but most people call it the combat log now.
