[JASS] FloatingText won't display

[Raven0]

This won't display for a reason which is beyond me :*(

function GetDamageText takes unit target returns nothing 
    local texttag dmgtxt
    set dmgtxt = CreateTextTag()
    
    call SetTextTagPosUnit(dmgtxt, target, 0)
    call SetTextTagText(dmgtxt, "hello", 13)
    call SetTextTagVisibility(dmgtxt, true)
    call SetTextTagPermanent(dmgtxt, false)
    call SetTextTagVelocity(dmgtxt, 64, 90)
    call SetTextTagFadepoint(dmgtxt, 1.6)
    call SetTextTagLifespan(dmgtxt, 3)
    call SetTextTagColor(dmgtxt, 255, 255, 255, 0)
endfunction

• Floating Text Test
  • Events
    • Player - Player 1 (Red) types a chat message containing text as An exact match
  • Conditions
  • Actions
    • Set tempunit = Sage 0014 <gen>
    • Custom script: call GetDamageText(udg_tempunit)

Go and look at how SetTextTagTextBJ works.

Spoiler

function SetTextTagTextBJ takes texttag tt, string s, real size returns nothing
    local real textHeight = TextTagSize2Height(size)

    call SetTextTagText(tt, s, textHeight)
endfunction

Also, its a damn good thing texttags dont actually make use of their alpha channel. Else i would have informed you that setting alpha to zero normally makes everything disappear completely.

Edit: Good point about the velocities, WaterKnight.

 

[WaterKnight]

Font size and velocities are a bit high. GUI/BJ-functions use these conversions:

function TextTagSize2Height takes real size returns real
    return size * 0.023 / 10
endfunction

function TextTagSpeed2Velocity takes real speed returns real
    return speed * 0.071 / 128
endfunction

So a GUI font size of 13 would be about 0.0299 using the native function, velocities of 64/90 would be 0.0355/~0.05.

edit: hi deaod

 

[Raven0]

Ah I see

I'll do the conversions and test it out right now

EDIT - everything works, ty!

For future reference when you're trying to do something that you know can be done in GUI, just take a look at some of blizzard's natives to look at some precautions they may have taken when writing them. They're not always 100% right, but sometimes they'll include something that you wouldn't have thought was related (or that you forgot about).
