Hmm... a topic like this already exists but it's locked for some reason (http://forum.chaosforge.org/index.php/topic,1222.0.html)
1) It's not a stickied thread.
2) It's 16 months old.
Other than that, however, I would vote to sticky it somewhere, maybe even in the Post Mortem forum.
I think you can add on screen stuff to a video with youtube but I don't know how.
I tried CamStudio but I couldn't get it to work with my sound card. BB Flashback express worked: http://www.bbsoftware.co.uk/BBFlashBack_FreePlayer.aspx
I'll be sure to look at both of those options, thanks.
I still don't really understand all the different shotgun firing patterns, mostly trial and error. What weapons does it matter which direction you come from?
Weapons that can have firing issues due to corners and the like (not including misfires, mind you) are those that have an inherent inaccuracy in the weapon itself. Typically, this is found in the shotgun, combat shotgun, double shotgun, and all exotic/unique variants. BFG 10K also falls under this category, as it is inaccurate as all hell.
Whether or not you can fire directly along a corner depends on the direction of the corner and the direction you want to fire. Like so:
@###### <--- will work with shotgun
......X
......X <--- will not work with shotgun
@######
B#
.# <--- will not work with combat shotgun
.@
That last one really, really sucks, by the way. The combat shotgun is the best example of what will and won't work: the shotgun has roughly the same corner problems, except that even good corners have a decreased range shooting down them; the double shotgun is kind of an anomaly due to its really huge burst range, but it's about the same anyway (and not much damage range to boot).
There are some awkward shots you can pull off, however, that give you an advantage over most enemies:
.....B
..X... <--- won't hit with combat shotgun
..####
@.####
.....B
...X.. <--- will hit with combat shotgun
..####
@.####
(Note: I don't know if this will EXACTLY work, but I do know it's the right direction/corner.) So it's kind of like an advanced corner-shot, if you will, that strikes the enemy without retaliation. Also, with the range of the combat, the enemy could be several tiles beyond the position in the picture and still take damage, so you have a lot of time luring it out properly.
As a rule of thumb, your ideal shots are shooting from above or from the left, and your worst shots are shooting from below or from the right.
