Is it possible to have own setup() and draw() for different scenes?

ysleungrockman

In my game, there are multiple scenes. I want to define different scenes in different classes. I don't want to make the game load everything in the beginning and only load when the scene is loaded. Can I make their own setup() and draw() for those classes? If yes, how can I call those setup() and draw() in the main program? If no, how can I make the code to make the game work as said above?

this can be achieved easily.

setup and draw are fixed names though, so you need to work around them.

What you do: have a int sceneCount - you'll often see it in the forum as state.

in setup() do only what is done once (size) and everything for scene 0

now in draw use

switch (sceneCount) { 

and go to different functions from here : drawForSceneZero, etc.

once you need to step from scene 0 to 1 you you increase sceneCount by one and call setupForScene1 etc.

• to make this work you need this approach also in keyPressed, mousePressed etc. : switch (sceneCount) {

unless all keys do the same in all scenes

when you have a startScreen or a helpScreen, these are also scenes (or treated as one)

finally instead of saying scene 0, 1, 2 etc. you can give them names

final int sceneHobbington = 0;
final int sceneAtTheMountain = 1;
// etc. - values that sceneCount can have
