Combining sketches (one video player, one rain maker)

in Core Library Questions • 6 months ago

I have two sketches that I am trying to combine. I was trying to treat each sketch as a separate function but I am running into problems due to one of the sketches being one that simply plays a video. (Sound no picture etc.) The aim is for the video to play once and then move onto the rain straight after, although it seems latency is unavoidable.

My attempts have all been a mess so I will upload the sketches separately in hopes someone may have a suggestion!

Video:

import processing.video.*;
Movie myMovie;
void setup() {
size(1280, 720);
background(0);
// Load and play the video in a loop
myMovie = new Movie(this, "CBS.mov");
myMovie.loop();
}
void movieEvent(Movie myMovie) {
myMovie.read();
}
void draw() {
image(myMovie,0,0);
delay (25);
}

Rain:

int rainNum = 100;
ArrayList rain = new ArrayList();
ArrayList splash = new ArrayList();
float current;
float reseed = random(0, .2);
void setup()
{
size(600, 600, P3D);
colorMode(HSB, 100);
background(0);
rain.add(new Rain());
current = millis();
}
void draw()
{
background (0);
blur(50);
strokeWeight(9);
stroke(255, 2, 2);
line (width/2.0, 0, 100,
width/2.0, 0, 200 );
if ((millis()-current)/1>reseed &&
rain.size()<150)
{
rain.add(new Rain());
float reseed = random(0, .2);
current = millis();
}
for (int i=0 ; i<rain.size() ; i++)
{
Rain rainT = (Rain) rain.get(i);
rainT.calculate();
rainT.draw();
if (rainT.position.y>height)
{
for (int k = 0 ; k<random(5,10) ; k++)
{
splash.add(new Splash(rainT.position.x, height, rainT.position.z));
}
rain.remove(i);
float rand = random(0, 100);
if (rand>10&&rain.size()<150)
rain.add(new Rain());
}
}
for (int i=0 ; i<splash.size() ; i++)
{
Splash spl = (Splash) splash.get(i);
spl.calculate();
spl.draw();
if (spl.position.y>height)
splash.remove(i);
}
}
void blur(float trans)
{
noStroke();
fill(0, trans);
rect(0, 0, width, height);
}
// ==========================================
public class Rain
{
PVector position, pposition, speed;
float col;
public Rain()
{
position = new PVector(random(0, width), -500, random(0, 800));
pposition = position;
speed = new PVector(0, 0);
col = random(30, 100);
}
void draw()
{
stroke(100, col);
strokeWeight(2);
line(position.x, position.y, position.z, pposition.x, pposition.y, position.z);
//ellipse(position.x,position.y,5,5);
}
void calculate()
{
pposition = new PVector(position.x, position.y);
gravity();
}
void gravity()
{
speed.y += .2;
speed.x += .01;
position.add(speed);
}
}
public class Splash
{
PVector position, speed;
public Splash(float x, float y, float z)
{
float angle = random(PI, TWO_PI);
float distance = random(1, 5);
float xx = cos(angle)*distance;
float yy = sin(angle)*distance;
position = new PVector(x, y, z);
speed = new PVector(xx, yy);
}
public void draw()
{
strokeWeight(1);
stroke(100, 50);
fill(100, 100);
// ellipse(position.x, position.y, 2, 2 );
point(position.x, position.y, position.z );
}
void calculate()
{
gravity();
speed.x*=0.98;
speed.y*=0.98;
position.add(speed);
}
void gravity()
{
speed.y+=.2;
}
}

Thanks,

Looks simple enough...
The first sketch is the simplest, you can copy parts of it into the second one.
Declare the movie in the global section of the sketch, skip the size declaration, initialize the movie in setup().
And in draw(), put the image() call just after background() (or it replaces it, if the movie is full screen). I think you should remove the blur() call, too.

Hey, I have update the video sketch since this attempt and now I am even more confused!

//instatiate our classes
sketch = new videoSketch(width, height);

background(0);

sketch.happen();
sketch2.happen();

Apparently, I suck at explaining things...
But I don't remember mentioning to change the sketches into separate classes, my remarks was about copying parts of one sketch into the other, which becomes the main and only sketch.
You cannot put code like a size() call directly inside a class body, anyway.
