radar area on custom radar

[kasya85]

Guys, I need your help

I have GTA V style radar

I need that radar areas shows on my radar

createRadarArea

code of the radar

local enableBlips = true
local renderNorthBlip = true
local alwaysRenderMap = false

local worldW, worldH = 3072, 3072 
local blip = 12 

local sx, sy = guiGetScreenSize()
local rt = dxCreateRenderTarget(290, 175)
local xFactor, yFactor = sx/1366, sy/768
local yFactor = xFactor


function findRotation(x1,y1,x2,y2) 
  local t = -math.deg(math.atan2(x2-x1,y2-y1))
  if t < 0 then t = t + 360 end;
  return t;
end
function getPointFromDistanceRotation(x, y, dist, angle) 
    local a = math.rad(90 - angle);
    local dx = math.cos(a) * dist;
    local dy = math.sin(a) * dist;
    return x+dx, y+dy;
end

function drawRadar()
	if (not isPlayerMapVisible()) then
		local mW, mH = dxGetMaterialSize(rt)
		local x, y = getElementPosition(localPlayer)
		local X, Y = mW/2 -(x/(6000/worldW)), mH/2 +(y/(6000/worldH))
		local camX,camY,camZ = getElementRotation(getCamera())
		dxSetRenderTarget(rt, true)
		if alwaysRenderMap or getElementInterior(localPlayer) == 0 then
			dxDrawRectangle(0, 0, mW, mH, 0xFF7CA7D1) --render background
			dxDrawImage(X - worldW/2, mH/5 + (Y - worldH/2), worldW, worldH, "image/world.jpg", camZ, (x/(6000/worldW)), -(y/(6000/worldH)), tocolor(255, 255, 255, 255))
		end
		dxSetRenderTarget()
		dxDrawRectangle((10)*xFactor+30, sy-((200+10))*yFactor, (300)*xFactor, (185)*yFactor, tocolor(0, 0, 0, 175))
		dxDrawImage((10+5)*xFactor+30, sy-((200+5))*yFactor, (300-10)*xFactor, (175)*yFactor, rt, 0, 0, 0, tocolor(255, 255, 255, 150))
		local rx, ry, rz = getElementRotation(localPlayer)
		local lB = (15)*xFactor
		local rB = (15+290)*xFactor
		local tB = sy-(205)*yFactor
		local bB = tB + (175)*yFactor
		local cX, cY = (rB+lB)/2, (tB+bB)/2 +(35)*yFactor
		local toLeft, toTop, toRight, toBottom = cX-lB, cY-tB, rB-cX, bB-cY
		

		
		for i, v in ipairs( getElementsByType('radararea') ) do 
      
        	--I DONT WANT TO DO

  
  
        end 

		
		if renderNorthBlip then
			local rot = -camZ+180
			local bpx, bpy = getPointFromDistanceRotation(cX, cY, math.sqrt(toTop^2 + toRight^2), rot) --get position
			local bpx = math.max(lB, math.min(rB, bpx))
			local bpy = math.max(tB, math.min(bB, bpy)) --cap position to screen
			local dist = getDistanceBetweenPoints2D(cX, cY, bpx, bpy) --get distance to the capped position
			local bpx, bpy = getPointFromDistanceRotation(cX, cY, dist, rot) --re-calculate position based on new distance
			if bpx and bpy then --if position was obtained successfully
				local bpx = math.max(lB, math.min(rB, bpx))
				local bpy = math.max(tB, math.min(bB, bpy)) --cap position just in case
				dxDrawImage(bpx -(blip*2)/2+30, bpy -(blip*2)/2, blip*2, blip*2, "image/blip/4.png", 0, 0, 0) --draw north (4) blip
			end
		end
		dxDrawImage(cX -(blip*2)*xFactor/2+30, cY -(blip*2)*yFactor/2, (blip*2)*xFactor, (blip*2)*yFactor, "image/player.png", camZ-rz, 0, 0)
	end
end
addEventHandler("onClientRender", root, drawRadar)

 

I need advice, my math skill isn't good so I need your help guys 

[Dimos7]

if understand correctly you want to apear where are you on the radar?

[raynner]

No he wants to know how to introduce radar rendering areas (rectangle area) on his mini map
