draw empty circle

[Tekken]

Hi I'd like to draw an empty circle like this one:

I'm currently using the example from https://wiki.multitheftauto.com/wiki/DxDrawLine but it's not a perfect circle and yet very demanding.

I was wondering if there's a better way of doing this

 

Thanks

This one is less demanding:

Photoshop:

Create a png image (256 × 256), with .

• Give  black borders.
• Fill with a white colour if always filled, else use behind the image.
   

If filled with a white colour, it can be re-coloured with:

tocolor(255,255,255,255)

Create texture with mipmaps enabled:

What does mipmaps do?

Try to give the image

dxDrawCircle returns a filled circle, the idea behind this is to create those circles as health indicators.

Haven’t tried making alpha 0 to center color tho

Oh sorry, I meant this one:

but you still need that image to make the borders smooth.

try this

function dxDrawCircle2( posX, posY, radius, width, angleAmount, startAngle, stopAngle, color, postGUI )
		if ( type( posX ) ~= "number" ) or ( type( posY ) ~= "number" ) then
			return false
		end

		radius = type( radius ) == "number" and radius or 50
		width = type( width ) == "number" and width or 5
		startAngle =  type( startAngle ) == "number" and startAngle or 0, 0, 360
		stopAngle =  type( stopAngle ) == "number" and stopAngle or 360, 0, 360
		color = color or tocolor( 255, 255, 255, 100 )
		postGUI = type( postGUI ) == "boolean" and postGUI or false

		startAngle = startAngle-90;
		stopAngle = stopAngle-90;

		if ( stopAngle < startAngle ) then
			local tempAngle = stopAngle
			stopAngle = startAngle
			startAngle = tempAngle
		end

		local multiby = 50;

		if (radius >= 1000) then multiby = 3000; end

		for i = startAngle, stopAngle, multiby/radius do
			local startX = math.cos( math.rad( i ) ) * ( radius - width )
			local startY = math.sin( math.rad( i ) ) * ( radius - width )
			local endX = math.cos( math.rad( i ) ) * ( radius + width )
			local endY = math.sin( math.rad( i ) ) * ( radius + width )

			dxDrawLine( startX + posX, startY + posY, endX + posX, endY + posY, color, width, postGUI )
		end

		return true
	end

i use this method with a circle image png
