Need help with Nameplate Castbar

[Basso]

I'm working on a little nameplate addon but i got two problems left i can't solve at the moment.

spellIcon:ClearAllPoints(); 
	spellIcon:SetWidth(CASTBAR_HEIGHT * (BAR_BORDER + 1)); 
	spellIcon:SetHeight(CASTBAR_HEIGHT * (BAR_BORDER + 1)); 
	spellIcon:SetPoint("BOTTOMRIGHT", castBar, "BOTTOMLEFT", -4, 0);
	
	
	local SpellIconOverlay = castBar:CreateTexture(nil, "MEDIUM", nil, -2); 
	SpellIconOverlay:SetTexture("Interface\\AddOns\\Test\\SpellIcon"); 
	SpellIconOverlay:SetVertexColor(0, 0, 0); 
	SpellIconOverlay:SetWidth((CASTBAR_HEIGHT * (BAR_BORDER + 1)) + 1); 
	SpellIconOverlay:SetHeight((CASTBAR_HEIGHT * (BAR_BORDER + 1)) + 1); 
	SpellIconOverlay:SetPoint("CENTER", castBar.spellIcon, "CENTER", 0, 0);

This is the positioning of the Castbar Spell Icon and this works so far, my Problem is the overlay always
stays behind the actual spell icon, and if i try to us :SetFrameLevel("LOW") on the Spellicon i get bombed
with this error:

Message: ...e\AddOns\Test\Test.lua:173: attempt to call method 'SetFrameLevel' (a nil value)

My idea was that maybe the spell icon stuff is further splitted in a table but i can't find a list of it.


the second Problem is the spell name, i want to shorten it if its gets longer then a specific amount
of letters, i have a function for that which i use on the name of the unit that works fine, but i can't use
it on the CastbarText, at the moment it seems to me that it is the same problem as above.

same attempt like on the name:

castBar.spellName = utf8sub(castBar.spellName:GetText(), 27, false);

the error:

Message: ...e\AddOns\Test\Test.lua:18: attempt to index local 'string' (a nil value)

Anyone knows a solution?
Or simply has a list of the content of these Tables i seem to dumb to find ?

Thanks,
Basso

that the whole code of the nameplate addon im modifying for personal use.

Your first error is because you try to call SetFrameLevel on a texture and it's only works on frames.

The second error could be caused because some spells have no names or you call it too early.

i could sort out the second error now, the shortening works fine now.
thanks for your hint.

but im at my wits end with the fucking border
but without it it looks somewhat stupid, i love clean black borders
green one for better visibility as attachment.

is there any simple way to put my border overlay over the spellIcon im overlooking ?
creating a frame over it is to much of code and workarounds for that, because i also
need to show and hide it dynamically.

I could suggest you to use one of these icon packs:

That would be the easiest way.
