[General] Text Tags not centered

[Bribe]

In the DamageEngine and Heal Event demos, I have text tags display certain data depending on the event. The text tags are always to the upper-right of the unit... I have tried creating the text tag on both unit or unit position, but it's all the same. Anyone else have this issue before?

I've never seen a text tag actually center when using "above" a unit. The first character will start above the unit, and then grow to the right. I don't think its possible to actually center long text over a unit. You would have to use a point and then offset it to the left of the unit if you actually want it centered.

I gotcha, so it's not just my PC glitching out. So I just have to subtract something from the X-axis to get it to line up the way I want. Simple enough considering the text tag width is typically 2 digits.

No, your PC isn't glitched or something. What's happening is really logical. The unit's position is actually the very origin of the unit, probably centered between the leg (unless it's some alien, or a horse). So when creating floating text tags , the direction is always from the left where the position of unit is, towards the right (Since Warcraft is a left-2-right's lang'ed)

The only way , is what "KILLCIDE" has stated, which is to use the "Polar Offset" option.

This is an image (Never get surprised by my drawing skills) :

Thanks jon, I would give you rep for that neat drawing, too, but I already gave you rep in that other guy's thread.

I've used this function to display centered text above items/units and it works well.

function DisplayTextTag takes string s ,real x, real y returns nothing
    local integer len = StringLength(s) * 3
    local real life = len / 7.5
    local texttag txt = CreateTextTag()
        call SetTextTagTextBJ(txt, s, 8)
        call SetTextTagPos(txt, x - len, y, 100)
        call SetTextTagColor(txt, 255, 255, 255, 220)
        call SetTextTagPermanent( txt, false )
        call SetTextTagLifespan( txt, life )
        call SetTextTagFadepoint( txt, 3.00 )
        call SetTextTagVelocityBJ( txt, 0, 90 )
    set txt = null
        
endfunction

the "life" var and length var are directly related to font size, (size 8 in this case). Hope it helps you to found a better way

What I did is play with the numbers until I found one that is mostly centered (x-32). The text tag is size 10.5 on average and is 2-3 characters, typically. You can see the results here: http://www.hiveworkshop.com/forums/spells-569/heal-event-gui-version-1-1-0-0-a-270928/

Yes, centering texttag is a very painful process.
It can also depends on your camerasetup distance, ( I realised this today while working on my UIpackage. )
aswell as the resolution you use in warcraft.

In vJass exists StringLength from PurgeandFire to get an accurate size of a string.
In GUI you could use something like the code posted from Avahor to estimate a string lenght.

In my opinion a perfect texttag position is not so important in your Heal Event resource.
Important is that a user can see to which unit the texttag belongs.

Ps: When using \n it gets really funny.
