CameraPick error

[SpiderPig]

Hi,

 

CameraPick() is givening me the following error;

 

"Unhandled exception at 0x752c9b60 in game-Release.exe: 0xC0000005: Access violation writing location 0x00000000."

 

and then it goes to this line in "Disassembly";

 

"752C9B60 rep movs dword ptr es:[edi],dword ptr [esi] "

 

This is my code;

 

TPick* pick

while( !KeyHit() && !AppTerminate() )
{
	if( !AppSuspended() ) // We are not in focus!
	{

		if(MouseHit(1))
		{
		if(CameraPick(pick,camera,Vec3(MouseX(),MouseY(),100),2,0,0))
		{
			EntityColor(pick->entity,Vec4(0,1,0,0));
		};
		};


		UpdatePlayer();

	                UpdateAppTime();
		UpdateWorld(AppSpeed()) ;

		// Render
		SetBuffer(gbuffer);
		RenderWorld();

		SetBuffer(BackBuffer());
		RenderLights(gbuffer);//ComputerTexture=GetColorBuffer(BackBuffer(),1);

		Flip(1) ;
	}
}

 

I tried it without setting the color of the picked entity or a mouse check but it still crashed.

What am I missing?

Haha, Just figured it out once I posted it...

 

I had to do;

 

TPick pick

 

instead of;

 

TPick* pick

 

and call on it like so;

 

if(MouseHit(1))
		{
		if(CameraPick(&pick,camera,Vec3(MouseX(),MouseY(),100),2,0,0))
		{
				EntityColor(pick.entity,Vec4(0,1,0,0));
		};
		};

 

Well, hope this helps someone else

 

Though how do I check which entity I'm picking in order to change the color of only that entity? The following code didn't work for me;

 

		if(MouseHit(1))
		{
		if(CameraPick(&pick,camera,Vec3(MouseX(),MouseY(),100),2,0,0))
		{
			if(pick.entity==cube)
			{
				EntityColor(pick.entity,Vec4(0,1,0,0));
			};
		};
		};
