Description

Have you ever had a hard time finding your cursor when a battle gets crazy? CursorTrail uses a built-in, animated model to produce a glowing effect around the cursor and a bright trail when the mouse is moved.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Options

The options window can be opened from the standard addons window, or by typing /CursorTrail or /ct. Settings are saved separately for each of your WoW characters, so your tank (for example), can have a different cursor effect than your dps characters.

Scale %: Controls the size of the effect. Can be 3 - 999.

Offsets: Moves the center of the effect. The first number box moves it horizontally (negative numbers move left, positive move right). The second number box moves it vertically (negative numbers move down, positive move up).

Opacity %: Controls how intense the effect is. 100% is brightest, while 0% is invisible.

Defaults: There are four default buttons, each with a different set of preset values. You can use them as-is, or as a starting point for your own effect.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Screenshots: www.curseforge.com/wow/addons/cursortrail/screenshots

Note: If the cursor trail effect unexpectedly disappears, you can quickly get it back by typing the slash command, /ct reload. (Even better, put that command in a WoW macro and place its button on a button bar.)

Note: A list of available slash commands can be seen by typing /ct help.

CursorTrail 8.1.5.2 is now available!

Added a fifth "Defaults" button with settings for a larger effect.

Made changes for upcoming release of WoW 8.2. (Special thanks goes to BaronPlucky for figuring this out.)

CursorTrail breaks in 8.2 PTR, "spells\\lightningboltivus_missile.mdx" as the model file comes up as invalid.

Thanks for the info. This could be really bad. That was the only model file that would follow the mouse cursor accurately. I will do my best to get it working again, but it might take a while ... if ever. :(

Thanks to the heads-up from the WeakAuras devs' notice on twitter about the 8.2 API changes (requirement of FileIDs being used instead of file paths), I was able to get CursorTrail to work in 8.2 PTR.

In CursorTrail.lua under the "Aliases to Globals" section I added:

local GetBuildInfo = GetBuildInfo
local select = select

Then in the "Constants" section I changed the kDefaultConfig table to:

defaultModelPath = 166498
if select(4, GetBuildInfo()) <= 80100 then defaultModelPath = "spells\lightningboltivus_missile.mdx" end

kDefaultConfig =
{
Version = kTheVersion,
Path = defaultModelPath,
BaseScale = 0.05,
BaseOfsX = -0.3, BaseOfsY = 4.3,
BaseStepX = 471, BaseStepY = 471, -- To increase range, decrease #s. To decrease range, increase #s.
UserScale = 1.0,
UserAlpha = 1.00, -- (Solid = 1.0. Transparent = 0.0)
UserOfsX = 0, UserOfsY = 0,
UserShowOnlyInCombat = false
}

Users logging into 8.2 will have to either run "/ct reset" or edit their characters savedvariables to use the model FileID, or I guess you could put the build version check in PlayerConfig_Load() and have it update the config with FileIDs?

Oh the FileID doesnt work in 8.1.5 so any config changes would have to make sure it's only used if on 8.2

Excellent work, Baron! I've had some real life stuff taking up much of my time, so this really helps. I will do my best to integrate your changes as soon as possible. :)

CursorTrail 8.1.5.2 should work with WoW 8.2, and automatically handle updating old settings files. (No need to do /ct reset, hopefully.)

Hello,

Having an issue where CursorTrail is going behind all UI elements, while the WoW default cursor hand stays above. This suddenly happened after not playing for awhile, and another friend noticed it yesterday.

I've tried the following

/ct reset

/ct reload

Disabling addons except CursorTrail

Reinstalling CursorTrail

Deleting CursorTrail and settings, then reinstalling

Other cursor Addons, such as Star Cursor, work correctly.

In reply to Zythos:

Well that's not good. CursorTrail only knows about the full screen size, so it has problems if another addon "changes" the usable screen size (such as adding borders/margins). Unfortunately, I have no solution for this.
I will take a look at StarCursor to see if something there that can help.

FOLLOW UP:

No luck investigating StarCursor. It uses a 2D texture for its effect, and moves the texture using a function called SetPoint. But that function has no effect on the 3D model used by CursorTrail. (FYI - CursorTrail moves the 3D model using the function SetPosition, which seems to be the cause of the problem you see.)

It sounds like your settings file for this addon might have missing data. Try doing /ct reset to create new (default) data, followed by a /reload to save the new data to the settings file.

Let me know if you still have the problem.

Hello there! A ways back you updated the mod on a request I made about a conflict with viewport addons like Sunn's Viewport addon, where the trail was not aligning with the cursor properly. It worked wonderfully until just today randomly where it's not following again. Any tips on what the problem could be because of?

In reply to deathgrip1092:

I remember this. I could not cause the problem you saw, but made changes back then based on a wild guess. Unfortunately, I don't have any new ideas to help this time. I've add this to my list of things to fix, but it may be a while until I look at it since real life is keeping me busy, and my free time is spent playing WoW more than programming for it. Wish I had better news to start off your new year.

Very understandable and no rush. I'll tinker with things on my own in the mean time.

Edit: Good news! Through random tinkering and good luck I fixed it myself by simply commenting out the lines:
local w2, h2 = Globals.UIParent:GetSize()
local scale2 = Globals.UIParent:GetEffectiveScale()
w2, h2 = floor(w2*scale2), floor(h2*scale2)

on lines 138 - 140. I have a feeling blizz changed something in the game on how it reads screen size

I hope you consider making more trails. This program is HIGHLY applicable to streamers, and the more options you give the more success you will have. You should try to market it to streamers also. It allows the viewers to more easily follow what healers are doing when they stream. By getting the streamers, you'll also be marketing it to the viewers. I've gotten some streams hooked on it.

stars, rainbow, rocket exhaust, ect

In reply to ChiefCougheeTalkin:

Cool, glad it's helping people out there.
Sadly, I spend 3 weeks when I wrote this addon trying to get other trail effects to work, but failed in the end. The animation effect is a built in WoW model, and while there are many other models to choose from, only the one I chose follows the mouse position correctly. Not sure why without talking to someone that understands the WoW models better than I do.

Hello!

I've noticed that when my UI gets hidden (Alt+Z keybind), the trail is removed until I reapply settings. I am assuming this means that the addon simply is missing the UI hide/show event somehow, and isn't reenabling the trail at that time.
Unfortunately, I don't seem to see the proper event in the Event API list, so I wasn't able to hack it myself. Are you aware of a good way to have the trail re-draw when the UI is shown after being hidden?

Thanks! Nice addon!
