This is the house layout of ground floor and first floor, the lights, radiators and windows turn on and off by clicking on them.
What i want to do is, when i click top left the OG button it will show the first floor and when i click the EG button it shows the ground floor but i dont know how can i do that?
currently each floor is in a seperate .pde file

Hello @lightbombs
If both floors are moved into a single pde It seems you could do this via a Boolean. If true, draw floor one to the screen, and if false, draw floor two to screen. Perhaps? And as you stated the OG / EG buttons are your target area to initiate on\off or true/false.

Very good answer here!
`boolean drawFloorOne = true;`
**Remark**
But is your Switch āAll Windows Openā referring to the current floor or to both floors?
When itās referring to the current floor only:
- When you have variables for the windows, heating and lights and you join the two pde-files to one Sketch (two tabs) make sure you name e.g. the lights like floor1Light0, floor1Light1 etc.
Then evaluate drawFloorOne not only in draw() but also in the mousePressed() function
```auto
if(drawFloorOne) {
// check switches for floor 1
floor1Light0=....
} else
{
// check switches for floor 2
floor2Light0=....
}
```

changed the topic category as it seems its in Processing (java) not p5.js š

@micuat Since no code shown in original post, how can you tell if in p5js or processing?
Just wonderingā¦

EDIT: oh never mind, it must be the .pde, š

Thatās a way but maybe you want to add more floors later. If thatās the case you could use an Enum.
Here an Example:
```auto
//you dont have to have the enum name in capital letters
FLOOR currFloor;
void setup() {
size(600, 600);
currFloor = FLOOR.EG;//or FLOOR.OG
}
void draw() {
if (currFloor == FLOOR.EG) {
//EG stuff
} else if (currFloor == FLOOR.OG) {
//OG stuff
}
}
enum FLOOR {
EG,
OG
};
```

Can you please elaborate? I donāt understand how additional floors can be pointed to. There is need of additional code to do this? I donāt have a JAVA background so any clarification is most appreciated. I did google and YouTube about enums but info did not completely translate to usage in your exampleā¦

Im not sure what you mean, but you can imagine that an enum is like a class, only that it has no cunstructure and cannot āstoreā integers or strings.
For Example:
```auto
class myClass {
//The class can "save" some intergers or Strings
int myInt;
String myString;
float myFloat;
PVector myPVector;//You know what I mean
myClass() {
//This is the cunstructure I think (im not sure because i am from germany) sry
}
}
//Enum:
enum myEnum {
Hello,
Enum,
OrSomethingLike,
That
}
//now we can create a variable
myClass myWonderfullClass;
myEnum myWonderfullEnum;
//You have to have a setup function otherwise you will get an error...
void setup() {
//You have to initialize the class I think im not sure
myWonderfullClass = new myClass();
//Enum:
//myWonderfullEnum = the "class" type of the variable in my case: myEnum
//and than a point so that you can get "access" to the type for Example : Hello or Enum or OrSomethingLike or That
myWonderfullEnum = myEnum.Hello;
//in the class its similar when you want to access a variable you can say thr name of the class in my case:
//myWonderfullClass then a point and than the variable name so:
//myWonderfullClass.myInt = 5;
}
```
I hope i could help you

Edit:
If you want (for Java generall) to do more with enums try this out:

A boolean distinguishes between 2 floors.
If you had more than 2 floors, you could use an int variable with can be 0,1,2ā¦ to indicate many floors. (Of course you still have to make these floors)
enum is now a way to tell the int which numbers it can hold so we canāt use any others (enumerated)
- by the way using an int to indicate a floor is similar to the concept of state / screen often seen here in the forum
