how to use "FX_DrawLine",
i did that for aknglock originally but maybe other can need it.

I already did a function to draw lines with hl2 materials but thats nice

nice work v3n0m4!!

didnt patrick show this on GD couple year ago
credits to pato too or no?

[..]credits to pato too or no?

no, no, no

[ᵁᴻᴷᴺᴼᵂᴻ]

credits to pato too or no?

yep if im right he used FX_DrawLine in old hlh,
but no i not used his code as example so its why he is not credited anyway i <3 him

ps:
who showed it is tetsuo if im right,
but new engine need to do some other call to draw that in 2d place "esp"

Hi,

i don?t know if v3n is using a new sdk or something

GetPlayerView(myView); //m_pClient
Push3DView(myView,0,false,0,m_pFrustum); //m_pRender
PopView(m_pFrustum); //m_pRender

These three functions dont seem to be in my sdk...

error C2039: 'GetPlayerView' : is not a member of 'IBaseClientDLL'
'PopView' : is not a member of 'IVRenderView' SDKivrenderview.h(151) : see declaration of 'IVRenderView'
error C2039: 'Push3DView' : is not a member of 'IVRenderView'

Do i have to update my sdk?

[floxy]

Seems, that u use the SDK of RH Pub BaseHook

Thx Gordon` 3>

from when is the sdk you posted?

I got some problems too.

I found this in my SDK:

extern IMesh* g_pMesh;
bool g_bMesh = false;

void FX_DrawLine( const Vector &start, const Vector &end, float scale, IMaterial *pMaterial, const color32 &color )
{
    g_bMesh = true;

    if (g_pMesh == NULL || pMaterial == NULL)
        return;


    Vector            lineDir, viewDir;
    //Get the proper orientation for the line
    VectorSubtract( end, start, lineDir );
    VectorSubtract( end, CurrentViewOrigin(), viewDir );
    
    Vector cross = lineDir.Cross( viewDir );

    VectorNormalize( cross );

    //Bind the material
    IMesh* pMesh = g_pMesh;

    if (!pMesh)
        return;
    
    CMeshBuilder meshBuilder;

    Vector            tmp;
    meshBuilder.Begin( pMesh, MATERIAL_QUADS, 1 );

    VectorMA( start, -scale, cross, tmp );
    meshBuilder.Position3fv( tmp.Base() );
    meshBuilder.TexCoord2f( 0, 1.0f, 1.0f );
    meshBuilder.Color4ub( color.r, color.g, color.b, color.a );
    meshBuilder.Normal3fv( cross.Base() );
    meshBuilder.AdvanceVertex();

    VectorMA( start, scale, cross, tmp );
    meshBuilder.Position3fv( tmp.Base() );
    meshBuilder.TexCoord2f( 0, 0.0f, 1.0f );
    meshBuilder.Color4ub( color.r, color.g, color.b, color.a );
    meshBuilder.Normal3fv( cross.Base() );
    meshBuilder.AdvanceVertex();

    VectorMA( end, scale, cross, tmp );
    meshBuilder.Position3fv( tmp.Base() );
    meshBuilder.TexCoord2f( 0, 0.0f, 0.0f );
    meshBuilder.Color4ub( color.r, color.g, color.b, color.a );
    meshBuilder.Normal3fv( cross.Base() );
    meshBuilder.AdvanceVertex();

    VectorMA( end, -scale, cross, tmp );
    meshBuilder.Position3fv( tmp.Base() );
    meshBuilder.TexCoord2f( 0, 1.0f, 0.0f );
    meshBuilder.Color4ub( color.r, color.g, color.b, color.a );
    meshBuilder.Normal3fv( cross.Base() );
    meshBuilder.AdvanceVertex();

    meshBuilder.End();
    pMesh->Draw();
} 

And I made the following fot a RH Base:

bool g_bMesh = false;

        return;

    //Get the proper orientation for the line
    VectorSubtract( end, start, lineDir );
    VectorSubtract( end, HalFLife2.m_pMyPlayer->BaseEnt()->EyePosition(), viewDir );
    
    Vector cross = lineDir.Cross( viewDir );
    VectorNormalize( cross );

    if (!pMesh)
        return;

    meshBuilder.Normal3fv( cross.Base() );
    meshBuilder.AdvanceVertex();

    meshBuilder.End();
    pMesh->Draw();
} 

Calling:

static color32 white = {255,255,255,255};

just update it and it should be fine.

Re: using FX_DrawLine?!

Incase someone is still using this GetDynamicMesh has switched place:

CMatRenderContextPtr pRenderContext( pMaterialSystem ); // credits: http://digitalpaintball.net
	
if( !pRenderContext )
	return;

IMesh* pMesh = pRenderContext->GetDynamicMesh( true, NULL, NULL, (IMaterial*)pModelHack->MatBeam );

also, Push3DView has one parameter less:

pRenderViewTable->Push3DView(myView,0,0,m_pFrustum);

Hook FindMaterial and:

IMaterial* pTemp = 0;
if(!strcmp(pTextureGroupName, "ClientEffect textures"))
{
	if(!strcmp(pMaterialName, "sprites/physbeam" ))
	{
		pModelHack->MatBeam = (IMaterial*)pTemp;
	}
	pLogger->Write( "logs\\textures.log", pMaterialName );
}

sprites/steam1
sprites/bubble
sprites/laserbeam
sprites/blueglow1
sprites/purpleglow1
sprites/purplelaser1
sprites/white
sprites/physbeam
sprites/gunsmoke

there's also plenty other cool sprites in TextureGroup "Other textures"
