Making race_delay_indicator show colored nicks

koragg · December 13, 2016

Whenever I try to put any kind of dxDrawText in that file it just draws it for less than a second and then text vanishes. Why? There are no errors, I replaced all needed things to dxDrawText lines and still it only draws it for half a second or less... Below is the original code, no idea what I gotta do so that it leaves dxDrawText stuff stay on-screen for longer.

local g_Root = getRootElement()
local g_ResRoot = getResourceRootElement(getThisResource())

				cps = ""

and wtf is this (dxText:create)? Why not the normal dxDrawText -.-

dugasz1 · December 13, 2016

When dxDrawText called then it just draw to the current frame. So you have to call it on every frame whit onClientRender. (Or onClientPreRender it depends on what do you want to do: Game Processing Order)

Thanks, I tried adding "onClientRender" to the function that draws it but still same result.

dugasz1 · December 13, 2016

Show us how did you do it or when do you want to draw it?

I just replaced line 33 and line 37 with dxDrawText and deleted lines 34, 38 and 40. I got rid of " delayDisplayFront " and replaced all lines in which text was being drawn with dxDrawText lines.

Edited December 13, 2016 by koragg
look just lines 30-43, if that gets fixed, the others are the same.

dugasz1 · December 13, 2016

I don't really know OOP in Lua but if showDelay called only once it doesn't good.

function drawText ( )
  	--draw what you want
    dxDrawText ( text, 44, 43 ) 
end

--Call this if you want it to be visible:
addEventHandler ( "onClientRender", root, drawText )

--Call this if you want it to disapear
removeEventHandler ( "onClientRender", root, drawText )

koragg · December 13, 2016

Did this and still same, half a second and rip text.

local screenW, screenH = guiGetScreenSize()

addEvent("showDelay", true)
function drawText(delayTime, optional)
		if tonumber(optional) then
			local cps = getElementData(g_Me, "race.checkpoint") - optional
			if cps < 2 then
				cps = ""
			else
				cps = "(-"..cps.."CPs) "
			end
			delayDisplayBehind:text("-"..msToTimeStr(delayTime).." "..cps..string.gsub(getPlayerName(source), "#%x%x%x%x%x%x", ""))
			delayDisplayBehind:visible(true)
			behindTick = getTickCount()
			setTimer(hideDelayDisplay, TIME_TO_DISPLAY, 1, false)
		elseif type(optional) == "table" then
			if delayTime < 0 then
				--delayDisplayFront:text("+"..msToTimeStr(-delayTime).." record #"..optional[1])
				dxDrawText("#FEFE22+"..msToTimeStr(-delayTime).." record #"..optional[1], screenW * 0.0000, screenH * 0.3657, screenW * 1.0000, screenH * 0.3972, tocolor(255, 255, 255, 255), 1.5, "default", "center", "center", false, false, false, true, false)
			elseif delayTime > 0 then
				--delayDisplayFront:text("-"..msToTimeStr(delayTime).." record #"..optional[1])
				dxDrawText("#00FFFF-"..msToTimeStr(delayTime).." record #"..optional[1], screenW * 0.0000, screenH * 0.3657, screenW * 1.0000, screenH * 0.3972, tocolor(255, 255, 255, 255), 1.00, "default", "center", "center", false, false, false, true, false)
			end
			--delayDisplayFront:visible(true)
			frontTick = getTickCount()
			setTimer(hideDelayDisplay, TIME_TO_DISPLAY, 1, true)
		else
            --[[local cps = getElementData(source, "race.checkpoint") - getElementData(g_Me, "race.checkpoint")
			if cps < 2 then
				cps = ""
			else
				cps = "(+"..cps.."CPs) "
			end
			delayDisplayFront:text("+"..msToTimeStr(delayTime).." "..cps..string.gsub(getPlayerName(source), "#%x%x%x%x%x%x", ""))
			delayDisplayFront:color(255, 0, 0)
			delayDisplayFront:visible(true)
			frontTick = getTickCount()
			setTimer(hideDelayDisplay, TIME_TO_DISPLAY, 1, true)--]]
		end
end
addEventHandler("showDelay", g_Root, drawText)
addEventHandler("onClientRender", root, drawText)

dugasz1 · December 13, 2016

This have no sense.
The showDelay should add the onClienRender event handler. (I guess you want to do that)
Now it have to create a lot of error (or just don't work). Because if the onClientRender call the function the delayTime, optional variables will be nill. So in 17 it will fail because nill<0 have no sense. (Or maybe nill<0 result will be false but i think it will be an error)

addEvent("showDelay", true)
addEventHandler("showDelay", g_Root,
	function(delayTime, optional)
		if tonumber(optional) then
			local cps = getElementData(g_Me, "race.checkpoint") - optional
			if cps < 2 then
				cps = ""
			else
    	--Etc....
        addEventHandler("onClientRender", root, drawText)
end)
    
function drawText ( )
  	--draw what you want
    dxDrawText ( text, 44, 43 ) 
end

Then remove it when needed.

koragg · December 14, 2016

Yea I know that would work normally but here I actually need to draw the " delayTime" and the "optional" variables, which are only accessible in the function tied to " showDelay ". So in other words, I can't draw it in another function and just add/remove event handlers So, really, no idea what to do to make this work...

dugasz1 · December 15, 2016

local lastDelayTime = false
local lastOptional = false

addEvent("showDelay", true)
addEventHandler("showDelay", g_Root,
	function(delayTime, optional)
		lastDelayTime = delayTime --"Save" it
		lastOptional = optional
    
		if tonumber(optional) then
			local cps = getElementData(g_Me, "race.checkpoint") - optional
			if cps < 2 then
				cps = ""
			else
    	--Etc....
        addEventHandler("onClientRender", root, drawText)
end)
    
function drawText ( )
  	--draw what you want
    dxDrawText ( text, 44, 43 ) 
end

You can do it like that.

(Sorry for late respone)
