Sadly these giant Switch Statements cause a heavy FPS drop in 3D content Games

How long have you been coding for? Is this your first game? I recommend you start with something basic and follow a STEP BY STEP tutorial to create a game first and then keep modifying and playing about with it to understand how the code works. I recommend using c sharp and the xna framework to get started…

Whoops found my mistake, I was typing my code in Dreamweaver. Silly me, no wonder my update didnt run. Dreamweavers compiler doesnt understand Visual Basic code who knew!

Anyways I got another problem, it seems my sprite class wont draw?

int Sprite

if(private override public Draw (int:) =! null)
{{
Fullbatch.sprite.draw.int;
Update.draw;
}}
endif;

This is really good advice, I can finally get to grips with changing the state of my game. Although im stuck with my code? Not sure if you can help.

enum eGameState {GSM_MENU, GSM_LEVEL, GSM_END};
eGameState gameState = GSM_MENU;
—————————–
switch (gameState)
{
if( gameState != broken)
{ case GSM_MENU :};
{
// Menu state
}
break;
if( gameState != broken)
{ case GSM_LEVEL :};
{

// Level state
}
break;
if( gameState != broken)
{ case GSM_BREAK :};
{
// End state
}
break;
}
————————-
if(Shoot == 1)
{
gameState = break;
}

I have used your integers but i cant get my head around fixing the game state once it ‘breaks’? Is this what patching a game means..

Sorry im new to Visual Basic.

You’re absolutely right, but I’m all in favour of simple concepts. This post will serve as a middleman between not knowing anything about game state management at all, and your very useful link. Thanks.

This is awful advice. A series of giant switch statement is very messy, especially in more complex games. If states are necessary for you, then you should be using states based on references and polymorphism.
A good, albeit not very thorough example is here (although it uses ugly C-like naming conventions):

Yes you can apply the same rules to any other game or software language out there. In fact, I’ve used this same technique in a Flash game myself.

That,s a great idea. Though I’m not much of a gamer but I will definitely try this tool in some
other directions connected with flash format. Thanks for sharing.
