This isn't fixed yet >:/

[SSFAN]

I use C++ for TV3D programming and had trouble to call this function

Code:

ITVCollisionResult CollisionResult;

CollisionResult = CreateTVCollisionResult();
...
...

if(CollisionResult->IsCollision())
{
   // do something
}

I expected this wll be fixed but it still crashes when I call this function.

Without this function, I can't progress my project anymore.

should I wait for 6.5?  :roll:  :roll:

Logically you never should create this TVCollisionResult class.
The class is returned by MousePick function, and is created inside the MousePick function.

I get the same thing with scene.advancedcollision.(EDIT: I didnt see he said it crashes, which mine doesn't, but hey ) The TV_COLLISIONRESULT I pass it has all the information except for TV_COLLISIONRESULT.hascollided ALWAYS returns false.

Example...

Code:

Scene.AdvancedCollision(OldPlayerPosition, NewPlayerPosition,CollisionResult, 0, TV_TESTTYPE_ACCURATETESTING, True)

Will always return FALSE, even when it has actually collided. If I change it to this...

Code:

CollisionResult.hascollided = Scene.AdvancedCollision(OldPlayerPosition, NewPlayerPosition,CollisionResult, 0, TV_TESTTYPE_ACCURATETESTING, True)

Then of course everything works as expected(with my code).

I think your just not filling the .hascollided with true or false

I called Scene->MousePick function before check collision but it still crashes.

can you please see my code and point me what's wrong?

Code:

#include "Header.h"

// Declare TrueVision
ITVEngine          TV;
ITVGlobals         Globals;
ITVInputEngine     Input;
ITVScene           Scene;
ITVLandscape       Land;

ITVScreen2DText    Text;


void InitializeEngine(HWND hWnd)
{
ShowCursor(false);

// Create Everything
TV = CreateTVEngine();
Globals = CreateTVGlobals();
Input = CreateTVInputEngine();

TexFactory = CreateTVTextureFactory();
CollisionResult = CreateTVCollisionResult();
Text = CreateTVScreen2DText();


// Initialize

Land->SetTexture(Globals->GetTex("tex_sand"),-1); // set landscape texture

long font = Text->TextureFont_Create("def_font","Arial",16,tvtrue,tvfalse,tvfalse,tvfalse); // create Arial font
}


void ShutdownEngine()
{

long  mX,mY;
short button;

Input->GetAbsMouseState(&mX,&mY,&button,&button,&button); // get mouse state

CollisionResult = Scene->MousePicking(mX,mY,TV_COLLIDE_LANDSCAPE,TV_TESTTYPE_ACCURATETESTING);

if(CollisionResult->IsCollision()) // BUG !!!!!!!!!!!!!!!!!!!!!!!!!!!
{
char buff[256];
sprintf(buff,"X : %.2f Y : %.2f Z : %.2f",CollisionResult->GetImpactPoint().x,CollisionResult->GetImpactPoint().y,CollisionResult->GetImpactPoint().z);
Text->TextureFont_DrawText(buff,5,5,RGBA(1,1,1,1),"");
}

Land->Render(tvtrue,tvtrue);           // render landscape

TV->RenderToScreen();                  // render scene
}

When this bug will be solved ? :oops:

I compiled the code that you write and the application do nothing. If I use

TrueVision3D::_TVCollisionResultPtr pCollisionResult;

then finally it works.

I know this issue is quite old but I'm seeking a some infos about that.   The previously mentionned solution did fixed my proplem too with the .isCollision() method   but now my application crashes when I close my window.

 void _Release() throw()
    {
        if (m_pInterface != NULL) {
            m_pInterface->Release();
        }
    }

  in comip.h is where my application breaks.


Any help would be appreciated.
