Hello I'm trying to make an animated wallpaper for my phone, but when I rotate the screen, the sketck gets distorted and out of the screen space.
I think this is a bug, but I want to know how to wrkarround that so my sketch work correctly.
I am using the lastest version of the android processing library, android 4.4.2.
This is when I do not rotate the screen:
This is when I rotate the screen:
This is the code:
int precision = 10;
float[] senos = new float[360 * precision];
float[] cosenos = new float[360 * precision];
float[] velocidad = new float[2];
float aceleracion;
void setup() {
fullScreen(P2D);
smooth(8);
stroke(255);
fill(255);
senos = calcularSenos(senos);
cosenos = calcularCosenos(cosenos);
for (int i = 0; i < velocidad.length; i++) {
velocidad[i] = random(1, 2);
}
}
void draw() {
background(0);
linea(width / 2, height, 180, height / 3);
aceleracion += .1;
}
float[] calcularSenos(float[] a) {
for (int i = 0; i < a.length; i++) {
a[i] = sin(radians((float)i * 360 / a.length));
}
return a;
}
float[] calcularCosenos(float[] a) {
for (int i = 0; i < a.length; i++) {
a[i] = cos(radians((float)i * 360 / a.length));
}
return a;
}
void linea(float principioX, float principioY, float angulo, float longitud) {
if (longitud >= 1) {
float finalX;
float finalY;
if (angulo >= 0) {
finalX = senos[(int)abs(angulo * precision % (360 * precision))] * longitud + principioX;
finalY = cosenos[(int)abs(angulo * precision % (360 * precision))] * longitud + principioY;
} else {
finalX = -senos[(int)abs(angulo * precision % (360 * precision))] * longitud + principioX;
finalY = cosenos[(int)abs(angulo * precision % (360 * precision))] * longitud + principioY;
}
line(principioX, principioY, finalX, finalY);
linea(finalX, finalY, angulo + velocidad[0] * aceleracion, longitud / 1.5);
linea(finalX, finalY, angulo - velocidad[1] * aceleracion, longitud / 1.5);
}
}

Can you create a ticket in https://github.com/processing/processing-android/issues
I cannot reproduce the problem in my device, using SG 8 and some another code. My wallpaper does not react to changes in orientation.
This next discussion might apply to you:
