[help] dxdrawcircle + anti alias

Recommended Posts

Posted (edited)

hey guys i got problem in shader i wanna put anti-alias in dxdrawcircle but its give me error please guys i need help :'(

i really tired to fix that and i don't know shader 

shader:

float sCircleHeightInPixel = 100;
float sCircleWidthInPixel = 100;
float sBorderWidthInPixel = 10;
float sAngleStart = -3.14;
float sAngleEnd = 3.14;

    float3 Position : POSITION0;
    float4 Diffuse : COLOR0;
    float2 TexCoord : TEXCOORD0;
};
struct PSInput
{
    float4 Position : POSITION0;
    float4 Diffuse : COLOR0;
    float4 Diffuse2 : COLOR1;
    float2 TexCoord : TEXCOORD0;
    float2 Settings : TEXCOORD1;
};


float4 PixelShaderFunction(float4 Diffuse : COLOR0, float2 TexCoord : TEXCOORD0) : COLOR0
{
    float2 uv = float2( TexCoord.x, TexCoord.y ) - float2( 0.5, 0.5 );

    float angle = atan2( -uv.x, uv.y );  // -PI to +PI
    if ( sAngleStart > sAngleEnd )
    {
        if ( angle < sAngleStart && angle > sAngleEnd )
            return 0;
    }
    else
    {
        if ( angle < sAngleStart || angle > sAngleEnd )
            return 0;
    }

    // Calc border width to use
    float2 vec = normalize( uv );
    float CircleRadiusInPixel = lerp( sCircleWidthInPixel, sCircleHeightInPixel, vec.y * vec.y );
    float borderWidth = sBorderWidthInPixel / CircleRadiusInPixel;

    // Check if pixel is inside circle
    float dist =  sqrt( dot( uv, uv ) );
    if ( ( dist > 0.5 ) || ( dist < 0.5 - borderWidth ) )
        return 0;
    else 
        return Diffuse;

i rlly tired to fix that :~

Afaik I said in my pm's that you have to use the MTA function.

https://wiki.multitheftauto.com/wiki/DxDrawCircle

 

And now you are still asking for help for a shader which you do not understand at all?

+ keep bumping, which I have warned you already for.

If you want people their attention, then atleast write a message with some useful content.
