Lag in CameraPick

[Gilmer]

Hello,

 

I'm using CameraPick, everything is working OK, but I noticed that the first Pick it takes longer, even causes a stop in fps, which can be?

 

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

// Faz um pick e pega a entidade e altera de cor
if (MouseHit(1))
{

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


// Update timing and world
UpdateAppTime();
UpdateWorld(AppSpeed()) ;

// Render
UpdateFramework();
RenderFramework();

//DrawText(10,10,"FPS: %f",FPS());

Flip(0);
}
}

hehe... if the first pick is on a high polygon object it will do that... if its a static mesh, then you can use the GMF processor on it, and it appears to help a little... if its a animated mesh, youre screwed... Ive gotten around it by causing the camera to do a pick on the high polygon animated mesh while the game is starting...

You can have a pre-caching function in your loading screen.

Yep, this is a known problem or side effect. It's due to the creation of an internal data structure in the engine. Current work around is to pick everything once prior to starting the game. Not great I know!

 

lol looks like two people beat me to it
