||
-> mapping | ||
|
||
map(); // ha 5 parametri | ||
|
||
map(cosa[l'input], startInput, EndInput, StartOutput, EndOutput); | ||
|
||
es su un dado (random da 0.00 a 1.00) | ||
map(r(1), 0.0, 1.0, 1, 6); | ||
|
||
es mouse e colore | ||
map(mouseX, 0, width, 0, 255); <-- una proporzione | ||
|
||
|
||
// LERP | ||
* calcolare dei valori intermedi tra i valori dati | ||
|
||
//funzione text(); <-- 3 parametri | ||
text("Stringa da scrivere", posizione1, posizione2); | ||
|
||
//esiste anche una versione a 5 parametri che fa scegliere anche il secondo punto per controllare l'area | ||
// utilizza come 0 il punto in basso a sinistra | ||
|
||
textSize(); <-- per cambiare la grandezza | ||
|
||
textAlign(); <-- allineamento | ||
|
||
//http track software | ||
|
||
//cambiare font | ||
1. createFont | ||
* PFont f; all'inizio | ||
* f = createFont("Calibri", ); | ||
* Come primo parametro il nome della famiglia del font | ||
* println(PFont.list()); //per listare quelli disponibili | ||
2. loadFont | ||
loadFont permette di allegare un file vlw al progetto | ||
prima fare CreateFont con il tool | ||
poi ad esempio f=loadFont("CourierNewPS-BoldMT-48.vlw", 54); | ||

## **ROTAZIONE** | ||
|
||
```processing | ||
int l =50; | ||
int a = 0; | ||
void setup(){ | ||
size(500, 500); | ||
rectMode(CENTER); | ||
noStroke(); | ||
} | ||
void draw(){ | ||
background(0); | ||
//fill(0,5); | ||
//rect(0, 0, width, height); | ||
translate(width/2, height/2); | ||
rotate(radians(a)); | ||
fill(255); | ||
rect(0, 0, l, l); | ||
a+=5; | ||
} | ||
``` | ||
|
||
```processing | ||
int l = 100; | ||
int a = 0; | ||
void setup(){ | ||
size(500, 500); | ||
noStroke(); | ||
rectMode(CENTER); | ||
} | ||
void draw(){ | ||
background(0); | ||
pushMatrix(); | ||
translate(width/2-100, height/2); | ||
rotate(radians(a)); //posso usare millis()/qualcosa per dare tempo | ||
fill(255); | ||
rect(0, 0, l, l); | ||
popMatrix(); | ||
pushMatrix(); | ||
translate(width/2+100, height/2); | ||
rotate(radians(-a)); | ||
rect(0, 0, l, l); | ||
popMatrix(); | ||
a+=5; | ||
} | ||
``` | ||
|
||
//scale(); | ||
//shear(); | ||
//quad(); <-- shape() ma quadrangolare | ||
|
||
* Lo scale è come uno zoom; ingrandisce anche lo stroke | ||
* all'esame NON utilizzare SCALE --> modificare le coordinate | ||
|
||
## **OOP** | ||
|
||
* un file per ogni classe -> come nome il nome della classe | ||
* struttura dati a metà tra array e lista | ||
* ArrayList (Java) | ||
* ArrayList<Ball> <--- oggetti appartenenti a questa classe e tutto ciò che eredita | ||
* Impropriamente si può fare ArrayList<Object> perché Object è una superclasse di tutti gli oggetti | ||
* v4 di processing ignora la denominazione private e rende tutto protected | ||
* super al posto di this per richiamare elementi della superclasse | ||
|
