Bug or intentional?

[Siegurt]

I've noticed that dazzling spray seems to hit/confuse me when I shoot it at a corner, but not at any other time, i'd say the ray is bouncing, but it doesn't seem to be bouncing at any other time:

Situation:

  Code:

##
##g
 g@
###


In order to hit both goblins I aim at X:

  Code:

##
#Xg
 g@
###


Result, the two goblins *and myself* get hit by dazzling spray, sometimes confusing me.

I suspect this is some SquareLOS related bug (range problems or something)

There's a kind of wall that reflects some beams; green crystal I think? Are the walls you're testing on made of that? I don't know if it reflects Dazzling Spray, though.

No, it's always done that. I think it always bounces one square if it hits a wall but you never notice except in that situation. If you look carefully the targeter will highlight your own square in the line of fire.

Long-known, standing bug.

Interesting, Doing a little more experimentation with it, it also happens when you fire directly into an adjacent wall (which isn't something that you'd typically want to do)

But even *more* interesting, is that magic dart, IMB, *but not searing ray* all appear to target your own square when firing point-blank into a wall or corner, although none of those actually hit you.

Additionally they all also target you (and dazzling spray actually hits you) if you fire *one offset* from a point blank wall, in a way that wouldn't bounce off and hit you (Even if it was a bouncing ray)

So aiming at X:

  Code:

###
 @
##X


will still target you.

This was around before square los, although I never knew it had to do with corners or walls. It's only happened to me once or twice, but it's good to know what to avoid in the future.

FR: While the root cause is being worked on/discovered, provide a prompt for situations in which this bug would happen.

suspect this would be harder than just fixing it
