MTA Background with blur?

[MisterQuestions]

Hey all i was trying to make an background for a login panel. but doesn't work i just get a orange ground laggy

Can some body help me?

This is my code:

client.lua

function DrawTheBlurredBackground() 
dxSetRenderTarget(); 
dxUpdateScreenSource( myScreenSource ); 
dxDrawImage( 0, 0, screenW, screenH, myShader ); 
end 
  
function StartLoginPanel() 
showChat(false) 
showCursor(true) 
dxSetShaderValue( myShader, "ScreenSource", myScreenSource ); 
addEventHandler("onClientRender", root, DrawTheMainLoginPanel) 
addEventHandler( "onClientHUDRender", getRootElement(), DrawTheBlurredBackground ); 
end 
addEventHandler("onClientResourceStart",root,StartLoginPanel) 

BlurShader.fx

texture ScreenSource; 
float BlurStrength; 
float2 UVSize; 
  
sampler TextureSampler = sampler_state 
{ 
    Texture = <ScreenSource>; 
    MinFilter = Linear; 
    MagFilter = Linear; 
    MipFilter = Linear; 
    AddressU = Wrap; 
    AddressV = Wrap; 
}; 
  
static const float2 poisson[16] =  
{ 
        float2(-0.326212f, -0.40581f), 
        float2(-0.840144f, -0.07358f), 
        float2(-0.695914f, 0.457137f), 
        float2(-0.203345f, 0.620716f), 
        float2(0.96234f, -0.194983f), 
        float2(0.473434f, -0.480026f), 
        float2(0.519456f, 0.767022f), 
        float2(0.185461f, -0.893124f), 
        float2(0.507431f, 0.064425f), 
        float2(0.89642f, 0.412458f), 
        float2(-0.32194f, -0.932615f), 
        float2(-0.65432f, -0.87421f), 
        float2(-0.456899f, -0.633247f), 
        float2(-0.123456f, -0.865433f), 
        float2(-0.664332f, -0.25680f), 
        float2(-0.791559f, -0.59771f) 
}; 
  
float4 PixelShaderFunction(float2 TextureCoordinate : TEXCOORD0) : COLOR0 
{    
    float4 color = tex2D(TextureSampler, TextureCoordinate); 
     
    for(int i = 0; i < 16; i++) 
    { 
        float2 coord= TextureCoordinate.xy + (poisson[i] / UVSize * BlurStrength); 
        color += tex2D(TextureSampler, coord); 
    } 
  
    return(color/17); 
} 
  
technique BlurShader 
{ 
    pass Pass1 
    { 
        PixelShader = compile ps_2_0 PixelShaderFunction(); 
    } 
}

local screenWidth, screenHeight = guiGetScreenSize ( ) 
  
local quality = 50 -- 1% t/m 100% 
  
local scalingFactor = quality/100 
local myScreenSource = dxCreateScreenSource(screenWidth*scalingFactor, screenHeight*scalingFactor) 

Rendering with full resolution will lagg, because those functions are slow.

And post all required variables next time, now I am just gambling what the problem might be.

If it still does lagg after reducing the quality, you can also choose for an update after every 2 frames. (which will split up the fps in half)

I update it every frame with full resolution and there's no lag what so ever. Players don't complain.

[IIYAMA]

Hmm, disagree with you.

I am drawing my screen at 1920x1080, with 2 x 7970 cards(overkill) and yet I feel a strange kind of lagg.

But that without using a shader, which you probably do.

[Ren_712]

Dividing huge numbers per pixel has always been quite resource demanding.

I'd suggest rethinking the way you deal with that.

Also there is a resource on community that you might like to check out:

but why i just got n orange render laggy?

0 Blur

[ccw]

You're not setting BlurStrength or UVSize. Add something like this:

dxSetShaderValue( myShader, "BlurStrength", 1 ); 
dxSetShaderValue( myShader, "UVSize", screenWidth/8, screenHeight/8 );

Thanks worked ! [solved]

[MisterQuestions]

Hey got n problem

(Sorry for revive this post)

But when players enter just see a black background

But after some restarts of script ingame you can see blurred bground

Why?

[Gallardo9944]

Have you used fadeCamera?

[MisterQuestions]

Nope, fade its done later, but idk, it works sometimes others no weird thing...

onClientResourceStart is attached to root, which means it will be triggered for every starting resource.

Check all your scripts and ensure they use resourceRoot for onResourceStart/Stop and onClientResourceStart/Stop

Also, use 'debugscript 3' and fix all warnings.
