Injector: An Overview

The addon has been renamed Aptchecka, but is still available at WoWInterface. Functions remain the same.

I’ve used ’em all, raid frames that is, but the one that graces my screen now-a-days is a little known add-on called Injector.  I lovingly refer to it as a Grid replacement raid frame: it packs all the concise informational detail of Grid into a fine-tuned and very discretely light-weight package.  /crush

Now, I know I’ve mentioned in the past that Injector is only configurable by .lua.  This is true and untrue to a certain extent, in that it does have some in-game command lines.  However, the true “meat” of Injector can only be accessed through tampering with the .lua file.  For most users, I would argue that this presents no problem, as most of the needed functions are included very well within the add-on on set-up, and only die-hard tinkerers will really need to delve past the in-game interface, limited as it may be.

Out of the Box

Injector comes as a square configuration of raid frames with vertical health & mana bars.  Very spartan and grid-like.

It has the capacity to show up to 8 groups.  However, when a raid contains more than 5 groups, the bars will automatically scale to 80% of standard size.  This allows you to perfectly place and position your raid frames for raiding without worrying over much about stepping into Wintergrasp and either having no raid frames for groups 6-8 or having raid frames marching off the screen or into your regular field of vision. (I’m sorry I don’t have a picture, but I do not BG enough, and when I DO, it also requires me paying utmost attention to, well me, and not that pesky Print Screen button.)

My favorite thing about Injector, however, is how it handles buffs and debuffs.  So far, I have not had to add a single buff or debuff to Injector.  Lots of pictures incoming!


I’m not fast enough on the draw to catch all the buffs in one picture, so we’ve got quite a few to cover the complement of spells that priests cast.  First up Power Word: Fortitude & Divine Spirit!  PW: Fort is the white dot in the top left corner, and Divine Spirit is the purple dot immediately to the right of that.  It does not matter whether you use a 30 or 60 minute buff; both will appear in the same area.

Prayer of Mending is next up, and it will appear as a white dot in the upper right hand corner.  You’ll notice the size is a bit bigger.  Items with shorter cooldowns or needing immediate attention are always larger than buffs.  I was not in a position to gain pictures of the effect, however, as the PoM charges are used, the indicator will change color (up to and including the T7 bonus charge).  It was also “bounce” properly from character to character.

Renew will appear in the bottom right corner when cast.  It has a pie-cool-down which will be illustrated later.  It also has a rather interesting animation, with a large “pop” box going down to this size.  It in no way impedes visibility of the frame, but I wasn’t able to find a good way to show the animated effect.

Even “temporary” healing spells such as Prayer of Healing are visible with Injector.  PoH will flash as a yellow indicator in the upper right hand corner for any characters who received the heal.

Last, but certainly not least is Power Word: Shield.  It appears in the top middle as a yellow indicator.  It also has a pie-cooldown.  Weakened Soul appears in the same area, but has a lower priority, so will only show when PW: Shield is not active.

Other spells: Shadow Protection, Levitate, Magic (debuff), Disease (debuff)


Soulstone Resurrection, Blood Pact, Fel Intellegence


Blessings, Glyph of Holy Light, Magic (debuff), Disease (debuff), Poison (debuff)


It was easiest to show the flexibility of the shaman with a full-blown raid picture.

First up, we’ll discuss Earth Shield, a staple for restoration shamans.  My Earth Shield cast is the green box in the top center of the druid in group one, party member 4.  My partner’s earth shield is located on the warrior in group one, party member 1.  Yay for no more overwriting!

Riptide is located in the bottom right corner as a blue indicator.  The warrior in group four currently has a riptide tick up.

You’ll also notice Disease (debuffs) on several members in the bottom middle.

This picture shows chain heal bounces.  In the upper right corner is a yellow indicator showing every raid member you received a chain heal bounce.

Other spells: Poison (debuff), Curse (debuff)


Unfortunately, I don’t have a high enough level druid to show all the healing spells available.  In the top left corner you will see a pink indicator for Mark of the Wild, and the brown indicator immediately below is for Thorns.

Rejuvenation is the pinky-purple indicator in the bottom right.

Regrowth is the yellowish indicator in the top right.

Other Spells: Lifebloom (colored by stack), Wild Growth


Arcane Intellect is shown on all these nice party members.

Other spells: Focus Magic, Curse (debuff)

Other Cool Stuff

If we take another look at our boss image, we can see a couple of nifty things included with Injector.

Raid icons, as you can see here, are clearly visible.  Aggro is shown by the small red indicator in the bottom left.  You can clearly see dead party members >.>  By default, frames will be darker for more health, and lighter for health lost.

For you raid leaders, ready check notification is also set-up by default.

Here, you can clearly see an incoming heal for a player.  Libhealcomm is automatically loaded for all healing classes (priest, shaman, druid, and paladin).

See that big purple indicator on the left?  That’s a special ability cast by the boss.  Similar indicators show up on different boss fights (Blood Queen’s bite for example).

Final Notes

Injector is a very cool and handy add-on which works great for me almost entirely out of the box.  For the curious, I will be covering the line commands and making some basic changes to the .lua file to get full customization; however, those who are already experienced should have no trouble giving a slight tweak here and there.  I am a total novice when it comes to tweaking, and I’ve managed to make some minor changes (and prior to this last push) add some spells.  I’ve been using it for most of 3.0 and haven’t had a break, although several pushes have added more features.  If you’re looking to walk on the simple side of raid frames, give Injector a try!

    • Memory usage primarily. I tried it when Grid was having some breakage issues, and haven't gone back since.

    • I've enjoyed it, and it was super easy to get set up when my laptop died. No more waterfall menus!

  1. very shiny… may need to shelve VuhDo for this on priest… especially since changed over to macro mouseover heals instead of clique / vuhdo healing…. Good find!

    • I've been using it for a few months and it just keeps getting better! I still use clique, but I have had too many reports of bugginess with Vuhdo to ever do more than a test drive.

  2. I had initially skipped over this the first time you posted it since I read "tampering with the .lua" but reading it again I see that it isn't NECESSARY and I really wish I had read it all the way through earlier, haha.

    This looks great. I'm using Grid right now, but I am definitely into simple and I plan to try this out for sure. Thanks for sharing!

    • No problem. Some changes do require .lua tampering, and I am finishing up the posting on that since I got approval from the add-on developer to publish his code 🙂

      However, general resizing and moving can be done through slash commands. Grid is great, but I switched during a rocky period and never looked back.
