Radar Blips

[RenanPG]

hi everybody, i've made a radar in gta v style, but i don't know how to put blips there. And i need help to makes radar image rotate.

I don't know if you are using the same MTA radar functions or you created your own.. Did you create your own?

[RenanPG]

yes i created my own, using dxDrawImageSection.

I remember there was a very similar topic before, since I replied there.

Go search for it. It contains everything you need to get this done.

this viewtopic.php?f=91&t=71784&hilit=blip ??? but some codes were removed ;(

if someone want to help me, i can send my current codes by pm.

No Idea why that weird guy removed all the code that might help others..

But still, there a plenty of other topics.

And you could also try to do it on your own, its not that hard, just some testing needed.

Well, your whole code isn't needed but I would like to see how you are calculating the x and y for the dxDrawImageSection

Also, what is the size of the radar map image ? 3000x3000 ? 6000x6000 ?

Thanks

    local px = ((x + 6000) / 2) - 100 
    local py = ((-y + 6000) / 2) - 100 

 

The whole image is 6000x6000.

here is my map.

 

    if x >= -3200 then 
        if x <= 3200 then 
            if y >= -3200 then 
                if y <= 3200 then 
                imagem = "mapa.jpg" 
                else 
                imagem = "agua.png" 
                end 
            else 
            imagem = "agua.png" 
            end 
        else 
        imagem = "agua.png" 
        end 
    else 
    imagem = "agua.png" 
    end 

 

and i use that to replace txture when the player is in middle of the sea. that makes the map infinite.

Maybe this helps you, might be a bit tricky since its not the whole code of my radar, but maybe this gives you a basic idea of how you could do it.

  
local function getCameraRotation () 
    px, py, pz, lx, ly, lz = getCameraMatrix() 
    local rotz = 6.2831853071796 - math.atan2 ( ( lx - px ), ( ly - py ) ) % 6.2831853071796 
    local rotx = math.atan2 ( lz - pz, getDistanceBetweenPoints2D ( lx, ly, px, py ) ) 
    --Convert to degrees 
    rotx = math.deg(rotx) 
    rotz = math.deg(rotz)    
    return rotz 
end 
  
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);
