About
Adds casting bars to the target frame and optionally to various other unit frames. (Cast times are estimates only)
You can also modify your own player castbar.
Configuration
Castbars have configurable size, textures, positioning and more.
Type "/castbar" or go to "Escape -> Interface Options -> AddOns -> ClassicCastbars" to open the options panel.
FAQ
Q: Why are the cast timers incorrect when the target is downranking spells?
A: Blizzard removed cast related unit APIs and also spell IDs from the combat log in Classic, so there's no way
to distinguish between spell ranks anymore and thus this addon will always assume its the max rank being used. This will also affect mobs to a certain extent, but against mobs the addon will auto correct itself after the spell has successfully been cast once for that mob type. If you leave the zone or restart your game this data will be reset.
Q: Why are the cast timers incorrect for some max rank spells?
A: Certain spells have talents that reduce its cast time and these can't be tracked accurately in Classic.
This addon will instead assume that the target has all cast time reduction talents active. Cast pushback might also
sometimes give slight inconsistencies, especially if the target has talents that give chance to ignore pushback.
Q: Why are the castbar still shown even though the player or mob canceled the cast?
A: Classic has no event for cast stop so the castbar will be stopped on unit movement instead, but this feature is not
always 100% accurate. It is also disabled for mobs since some mobs can move while casting. For focus castbar, it is also disabled since it requires a valid unit ID to detect movement, and "focus" doesn't exist in Classic as a valid unit ID.
Q: The addon doesn't show any casts at all?
A: You most likely have a custom unit frame addon that conflicts with ClassicCastbars, or you disabled the addon
on the taint popup when trying to join a battleground.
Q: The addon sometimes doesn't show casts?
A: Blizzard recently nerfed the combat log range to 50 yards, so if you're far away from your target you won't see his cast. Even if you move into range you will still need to wait for the target to cast a new spell before you can see the castbar.
Q: The castbar has different anchor points for different characters?
A: Castbar's position and scale are always relative to the parent frame. You most likely have the target frame
positioned or scaled differently on your other character.
Q: Why can't I see castbars on friendly nameplates inside dungeons/raids?
A: Blizzard made a change in Legion that made nameplates unable to be modified while in instances due to it being
abused in raids to make them easier. This change also made it to Classic.
Q: Why is the castbar not showing Portals or Mounts?
A: These casts generate no combat log events.
Q: Can I see what cast is interruptible or not?
A: As of v1.3.0 this is now possible to a certain excent. If you interrupt a casting mob and it shows "immune", the addon will
remember this for the next time that spell is being cast and will show a grey uninterruptible spell indicator from then on. (See ingame options or changelogs for v1.3.0 for more detailed info)
Feel free to submit any more questions in the comment section below.
If for some reason the addon stopped working, try temporarily disabling all other addons too see if there's any conflicts, or run this macro ingame twice: (Will reset all castbar settings to default)
/run ClassicCastbarsDB=nil;ClassicCastbarsCharDB=nil;EnableAddOn("ClassicCastbars");EnableAddOn("ClassicCastbars_Options")ReloadUI();

The anchor frame used for the focus bar with XPerl isn't the best choice.
"XPerl_FocusportraitFrame" doesn't appear if the player has portraits disabled.
A better anchor frame would be "XPerl_Focushighlight"
(XPerl users: add "XPerl_Focushighlight" to the list of anchor frames under "focus" in AnchorManager.lua)
Cannot move the nameplate cast bar since TBC launch.
Hello! Love the addon, thank you! I don't appear to be able to move/change the bar that comes up for things like breathing and feign death. Is that setting available somewhere or is it not supported by ClassicCastbars?
I'm not able to see the castbars like the picture called nameplate2 under images on this page. I always have to look at the top left to see the castbars and it's very annoying. I can't figure this out can someone please help me?
the uninterrupt shield doesn't appear to be showing anymore. I'm not sure when this started.
Am I stupid or is there no option to move the player castbar?

I updated today and I'm still having issues. The target cast bar works properly, but the player cast bar doesn't "fill" or show the timer and then just stay stuck empty on my screen after completing a cast. I reset all the settings from the addon menu and I have had no luck. Anyone know?
In reply to alcatraz_dd:
Try temporarily disabling all other addons besides this one to see if there's any conflicts. Also check if you get any Lua errors by typing /console scriptErrors 1
Post a screenshot if any error pops up (or the addon causing conflicts) and I'll take a look at it.
In reply to Wardzx:
Thank you so much.
I did some testing and found out it was a conflict with Shadowed Unit Frames. They finally updated and a reset/reload fixed the issue.
Thank you !!
In the mean time I tried other castbars which either don't work or I don't liked the way they looked. So glad you fixed it. Many thanks.
Thank you SOOOOO much! You're a legend! <3
Version 1.4.0 now supports The Burning Crusade :) Make sure you download the correct zip file.
Note: This is the very first release for TBC pre-patch so expect possible minor bugs. Uninterruptible border shield is not yet supported but will be in the future.
Arena and party castbars are mostly untested and default off.
There's currently no way to distinguish between failed and successfully interrupted casts. (Will try fix later)
If you copied your settings over from Classic Vanilla you might have to reset the addon.
In reply to Wardzx:
Thanks for the update! How are you going to support the uninterruptible spells in an absence of an official API?
In reply to Daeveren:
Np :) There's no built in API for it, but you can still parse the combat log to see if an interrupt was immuned or not while the enemy is casting. That way the addon can learn over time which spells can be interrupted or not. Temporary immunities from auras like paladin bubble will also be taken into account. For players there will be a pre-determined list of uninterruptible spells stored in the addon most likely.
This addon has some REALLY nice features that TBC cast bars do not have. I know you have stated you currently don't have the time, but if you rewrite this for TBC a ton of players, including myself, would greatly appreciate/enjoy it. I HOPE to see this in the future, just as it was in Classic Vanilla. <@:)
Seems TBC has castbars without this addon. Aoes this addon still have a function for tbc?
In reply to lostboy29:
Indeed, cast bars seems to exist in BCC. Funny thought Blizzard cast bars seems bugged on nameplates, we see the bar but not the spell name, lol.
In reply to BaronDeathicon:
Is this actually a bug or is it just like this lol. Hope it's a bug and it gets fixed
