useful function

[Master_MTA]

hello there i created useful function that maybe help people a lot it should be a main mta sa function

it's used with dxDrawText

that function help you to get numbers of lines of text if u was used the wordbreak argument and set it to true in dxDrawText function

source code:

function getTextNumbersOfLines(text,borderheight,borderwidth,scale,font)


	if dxGetTextWidth(text,scale,font)>borderwidth then---if it's in new line then
	
		local totalHeight=borderheight/dxGetFontHeight(scale,font)----get number of lines that the box can contain it
			
		local percent=(borderwidth/dxGetTextWidth(text,scale,font)) *100---calculate some math :D get the percentage from the all width to the width of 1 line
		
		local heightoftext=(percent*totalHeight)/100
		
		local result=math.floor(dxGetFontHeight(scale,font)/heightoftext)
		
		return result
	end
	
return 1---else
end

syntax:

getTextNumbersOfLines(string text,float borderheight,float borderwidth,float scale,string/fontelement font)

arguments:

text: the text that you want to get the numbers of line of it

borderheight: the height of the border

borderwidth: the width of the border

scale: the scale of the text

font : can be an font element that created by dxcreating font functions or it can be one of

this:

• "default": Tahoma
• "default-bold": Tahoma Bold
• "clear": Verdana
• "arial": Arial
• "sans": Microsoft Sans Serif
• "pricedown": Pricedown (GTA's theme text)
• "bankgothic": Bank Gothic Medium
• "diploma": Diploma Regular
• "beckett": Beckett Regular

 

how to use: example--

addEventHandler('onClientRender',root,function()

dxDrawText ( 'hello world this is just test text to check word warp calculate function ', 200,200, 300, 400, tocolor(255,255,255,255),1,  "default", "left", "top", true,true, false)

end)

addCommandHandler('testheight',function()

print(getTextNumbersOfLines('hello world this is just test text to check word warp calculate function ',200,100,1,'default'))
print(dxGetFontHeight(1,'default'))

end)

 

what is the special about this function

we all know we can create our word break mechanism without using 

the word break argument but with this function you can use the wordbreak argument

and don't care about the mechanism

hope u like it enjoy

Update:(there was bug with dxgettextwidth it doesn't count the space after word warp any way solved)

source code:

function getTextNumbersOfLines(text,borderwidth,scale,font)
	
	local scale=scale or 1
	local font=font or 'default'

	if dxGetTextWidth(text,scale,font)>borderwidth then---if it's in new line then
		local mytext=''
		local numoflines=1
		for c in string.gmatch(text,"%w+") do

			mytext=mytext..' '..c
			local currentwidth=dxGetTextWidth(mytext,scale,font)
			
			if currentwidth>borderwidth then
			
				numoflines=numoflines+1
				mytext=c
		
			end
		end

		return numoflines
	
	
	end
	
return 1---else
end

Note:No need any more for borderheight argument
