[HELP] Making scroll...

[Scyrix]

Hi ,

I wanted to create a scroll for rectangles that i have inserted into a table. I tried to avoid rendertargets Does anyone have idea of how i can make that scroll so it acctually works.

Or maybe someone correct me because i might have made the whole function just wrong  

local przecho = {

    {1000.79, 1069.15, 11.07-1,"CODELV",981.18, 1070.89, 10.81-0.98}

}

local oknoprzecho = false

local data = nil

local gridlisto = {}

 

for _,v in ipairs(przecho) do

    local markerekPrzecho = createMarker(v[1],v[2],v[3],"cylinder",1.0,255,255,255,255)

    local markerOdbior = createMarker(v[5],v[6],v[7],"cylinder",2.0,255,255,255,255)

    addEventHandler("onClientMarkerHit",markerekPrzecho,function(plr)

        if plr == localPlayer then

        oknoprzecho = true

        showCursor(true)

        data = getElementData(localPlayer,"veh:list")

        showVehicles(748, 375, 416, 37)

        end

    end)

    addEventHandler("onClientMarkerHit",markerOdbior,function()

 

    end)

end

 

function showVehicles(x,y,z,h)

    local offset = 0

    for k,v in pairs(gridlisto) do

     gridlisto[k]=nil

    end

    for k,v in ipairs(data) do

    table.insert(gridlisto,{x=x,y=y+offset,z=z,h=h,model=v.model})

    offset = offset + 50

    end

    print(#gridlisto)

end

 

--dxDrawRectangle(732, 321, 450, 294, tocolor(255, 255, 255, 255), true)

addEventHandler("onClientRender", root,function()

    if oknoprzecho then

        dxDrawRectangle(561, 207, 798, 666, tocolor(32, 32, 32, 255), false)

        dxDrawRectangle(1290, 236, 41, 34, tocolor(255, 0, 0, 255), false)

            for i,v in ipairs(gridlisto) do

                dxDrawRectangle(v.x,v.y,v.z,v.h,tocolor(255,255,255,255))

                dxDrawText(v.model, v.x, v.y, v.z, v.h, tocolor(0, 0, 0, 255), 1.00, "default", "left", "top", false, false, false, false, false)

                end

 

    end

end)

 

addEventHandler("onClientClick",root,function(btn,state)

    if btn == "left" and state == "down" then

        if oknoprzecho then

            if isMouseIn(1290, 236, 41, 34) then

                oknoprzecho = false

                showCursor(false)

            end

            for k,v in ipairs(gridlisto) do  

                if isMouseIn(v.x, v.y, v.z, v.h) then

                    outputChatBox(v.model)

                end

            end

 

    end

end

end)

 

function isMouseIn( x, y, width, height )

    if ( not isCursorShowing( ) ) then

        return false

    end

    local sx, sy = guiGetScreenSize ( )

    local cx, cy = getCursorPosition ( )

    local cx, cy = ( cx * sx ), ( cy * sy )

   

    return ( ( cx >= x and cx <= x + width ) and ( cy >= y and cy <= y + height ) )

end

I leave you an example of how you could make a grid list without using rendertarget

 

  local items   = {"1", "2", "3", "4", "5", "6", "7", "8", "9", "10"}
  local scroll  = 0
  local maxRows = 5
  local select 
  
  local sx, sy = guiGetScreenSize()
  
  function onMouseScroll(bind,state)
     if state == "down" then 
	    if bind == "mouse_wheel_down" then
     	   if scroll < #items - maxRows then 
		      scroll = scroll + 1
		   end 
		else 
		    if scroll > 0 then 
			   scroll = scroll - 1
			end 
		end 
	 end 
  end 
  
  bindKey("mouse_wheel_down", "down", onMouseScroll)
  bindKey("mouse_wheel_up", "down", onMouseScroll)
  
  addEventHandler("onClientClick", root,
     function(_, state)
	    if state == "down" then 
	       local cache = 0
	       for i = 1 + scroll, maxRows + scroll do 
		      if isMouseInPosition(sx * .4, sy * .3 + cache, sx * .2, sy * 0.05) then 
		         select = i
				 return 
		      end 
		      cache = cache + sy * 0.05
		   end   		   
		end 
	 end 
  )
  
  
  addEventHandler("onClientRender", root,
     function()
	    local cache = 0
	    for i = 1 + scroll, maxRows + scroll do 
		   if isMouseInPosition(sx * .4, sy * .3 + cache, sx * .2, sy * 0.05) or select == i then 
		      dxDrawRectangle(sx * .4, sy * .3 + cache, sx * .2, sy * 0.05, tocolor(255, 255, 255, 100))
		      dxDrawText(items[i], sx * .4, sy * .3 + cache, sx * .6, sy * 0.35 + cache, tocolor(255, 255, 255))		   
		   else 
		      dxDrawRectangle(sx * .4, sy * .3 + cache, sx * .2, sy * 0.05, tocolor(0, 0, 0, 100))
		      dxDrawText(items[i], sx * .4, sy * .3 + cache, sx * .6, sy * 0.35 + cache, tocolor(255, 255, 255))
		   end 
		   cache = cache + sy * 0.05
		end   
		
		-- // draw scroll rectangle 
		local rx = sx * .6
		local ry = sy * .3
		local rw = sx * .01
		local rh = sy * 0.05 * maxRows
        local rh2 = sy * 0.05
		local pos = ((rh - rh2)   / (#items - maxRows)) * scroll
		dxDrawRectangle(rx, ry, rw, rh, tocolor(255, 255, 255))
		dxDrawRectangle(rx, ry + pos, rw, rh2, tocolor(0, 0, 0))		
	 end 
  )

Whats are cons and pros of using rendertarget for scroll system ?
