Zum Einstieg haben wir grundlegende Funktionen in Processing wie Zeichnen, Funktionen, Schleifen und Interaktionen repetiert.

LINES

size(500,500);
background(255);
smooth();

stroke(0,255,0);
strokeWeight(3);
line(10,10,200,200);

stroke(255,255,0);
strokeWeight(4);
line(50,100,300,300);

stroke(0,0,255);
strokeWeight(6);
line(50,400,500,300);

stroke(0,255,255);

ELLIPSE / ALPHAWERT


int xPos=10;

void setup()
{

background(0);
}

void draw()
{
//background(255);
noStroke();
fill(0,255,0,100);
ellipse(xPos,yPos,50,50);
}

void mouseDragged()
{

yPos=mouseY;

}



MOUSEPRESSED


int value = 0;

void setup()
{
size(500,500);
noStroke();
smooth();
}

void draw()
{
fill(value);
rect(250, 250, 100, 100);
}

void mousePressed() {
if(value == 0) {

} else {

}
}


KEYPRESSED

<pre>
void setup()
{

}

void draw()
{
