Adds ability to attack mobs by clicking their tile.
When someone clicks a tile with a weapon while off help intent, and if a mob is occupying that tile, the mob will be attacked as if they were clicked directly.
If more than one mob is on a tile, one is chosen randomly.
You cannot hit yourself by clicking your own tile.
Weapons with cleaving abilities will attempt a cleave on the tile clicked on, making it very easy to hit (simple) mobs with those weapons if near you.
Other changes.
Cleave proc can accept any atom now and not just a mob.
Also cleans up weapons deciding how they can cleave somewhat.
* POLARIS: Attack animations
* POLARIS: Overlay flick system
You can't do this in Byond, unfortunately, so here's some code from /tg/
* Make attack anims a preference
Does not use initial(pixel_x) and initial(pixel_y) for 'finishing' attack animations, so that mobs can have old_x and old_y updated to reflect a natural pixel offset (e.g. for mobs that are longer/taller than 32x32 and are nudged to fit into a tile).
For example, we have a 32x64 cyborg module which sets pixel_x, pixel_y, old_x, and old_y when selected, however attacking with it resets it to 0 as this doesn't respect old_x and old_y like all other mob anims do (see floating, etc).
Also why define this on atom and then literally never use it on anything other than a mob, in the... mob/animations.dm file?
_Sorry to keep making QOL PRs. I promise I'll send something cool eventually._
