BattleWatch is a combat monitor that represents your actions entirely visually. Unlike most combat logs, it presents you with an easy way to recognize the time between actions. It is also designed to let you carefully watch your usage of the global cooldown.
When you use an ability, it starts at the bottom of the "pit." If it triggers the global cooldown, the entire host frame will turn red until the GCD is inactive. The icon will scroll as time passes, and when it completely clears the GCD line is precisely when the GCD is inactive.
Abilities that don't trigger the GCD appear as faded and behave appropriately. Cast time is also represented: a successful spellcast shows as green, while a canceled or interrupted one shows as red. Channeled spells start as yellow and tend toward green as you invest cast time, or red as cast time is lost.
It takes spell haste, rogue GCD, etc. into account. The settings menu allows you to change speed, scroll direction, scale, whether the host is shown when inactive, size, and possibly another setting or two I can't remember.
As always, comments/suggestions/bug reports are welcomed :]
The documentation should be relatively up to date, so if you want to check out the code feel free. I'll answer any questions. Right now I need help with the following:
1. GCD table - if the GCD bar is inaccurate regarding any spell (not item), please leave a comment
2. Items - taking suggestions on how to handle items. Right now it just uses a question mark if it can't find the texture, but if anyone knows a better way to get item textures I'm all ears.
3. Debugging - right now BattleWatch will flush itself whenever something goes wrong, allowing it to continue functioning normally. Error reports, of course, are immensely helpful, but they'll only show through if you enable debugging. If anything goes wrong, use the flush command to clear a host's object table.
NOTE: BattleWatch may not behave nicely in a very laggy situation. There's nothing I can do about this, as lag warps the pacing and logic of events it relies on. (That's why one of the mind flays in the screenshots looks so long, heh.)
