Hello everyone!
I’m planning a game and I was wondering how it was done once the design was finished to create the home screen with a minimum of player interactivity: I was thinking of a “welcome to the game” and the pulsating classes to be written with “start playing” and maybe some other button with “rules” written where it then connects to a screen where I explain the rules of the game.
Can any of you direct me to the interactive part?
Thanks for anyone who wants to help me! 
Google state in this forum (it means screen you want to show)
Before setup () :
int state=0;
In draw():
Have a
if(state==0) {
// show initial screen
background (0);
text("Welcome!", 300,300);
...
}
else if(state==1){
//show game screen
background (0);
...
}
else if(state==2){
// show rules screen
background (0);
text("The rules", 30,30);
...
}
....
When state is 0 show the welcome screen in the if clause above
When it’s 1 show the game
When it’s 2 show rules
etc.
(Nothing in draw() should be allowed outside the if clause)
Have the same if clause structure in void mousePressed() and void keyPressed()
so only the mouse pressings for the current state are registered.
