MapInfo text overwriting itself

koragg · December 30, 2016

Hello, I'm facing a small but really annoying problem with the mapinfo script I'm using. Problem's that when I press the key (F5) to show mapinfo while text is still being drawn at the moment (fades away slowly) it just starts from the beginning again. This makes a really bad effect and also gets annoying if you just want to check toptimes as the mapinfo starts over and over again and again. I tried messing with timers and some booleans but no deal. Help?

function prerenderfix()
	fade = 0
	width, height = guiGetScreenSize()
	setTimer(function()
	check = 0
	end,50,1)
	if isEventHandlerAdded("onClientRender",getRootElement(),renderText) == false then
		addEventHandler("onClientRender",getRootElement(),renderText)
	end
end
bindKey("F5","down",prerenderfix)
-------------------------------------------------------------------------------------------------------------------------
function renderText()
	if fade <= 253 and check == 0 then
		fade = fade + 2
		dxDrawColorText("Map: "..name, 1, 1, width+1, height+1, tocolor(0,0,0,fade), (width/1660)*3, "sans", "center", "bottom")
		dxDrawColorText("#00FFFFMap: #FEFE22"..name, 0, 0, width, height, tocolor(255,255,255,fade), (width/1660)*3, "sans", "center", "bottom")
	elseif check == 0 then
		check = 1
		dxDrawColorText("Map: "..name, 1, 1, width+1, height+1, tocolor(0,0,0,255), (width/1660)*3, "sans", "center", "bottom")

I am not able to reproduce this bug with the code you provided.

So you're saying, it keeps on rolling even if you don't press the F5? Or what is it?

@myonlake that was just part of the code responsible for drawing. Here's full:

Well, when I press F5 the text fades in, stays a few seconds on screen and then fades out. And if I press F5 while the text is showing, it starts from the beginning again. I wanna make it so that if there's any text (map name, author or gamemode) on screen it wouldn't do anything when I press F5.

You can simply do a check if the check is set.

function prerenderfix( )
	if ( check ) and ( check ~= 6 ) then
		return
	end
	-- rest of the code...
end

Seems to work for me, anyway.

No need for the timer, by the way.
