week15👅💓👿😡
♥輸入一張圖片，印出pt的x=10
♥程式碼-
size(600,600);
PImage img=loadImage("img.jpg");
PVector pt=new PVector(10,20,0);
image(img,0,0);//顯示image
println(pt.x);//印出pt的x
float userX=10,userY=20,userZ=0;
float use2X=30,user2Y=40,user2Z=0;///before
PVector user=new PVector(10,20,0);
PVector user2=new PVector(30,40,0);//after

♥畫出一顆球
♥程式碼-
PVector user;
void setup(){
size(600,600);
user = new PVector(10,20);
}
void draw(){
background(255);
ellipse( user.x,user.y,20,20):
}

♥Y為彈弓，拖移滑鼠就能射出球(無限)
♥程式碼-
PVector user;
PVector Y,v=null;
void setup(){
size(600,400);
user = new PVector(100,300);
Y = new PVector(100,300);
}
void draw(){
background(255);
line( user.x,user.y,Y.x,Y.y);
textSize(40);
fill(255,0,0); text("Y",Y.x,Y.y);
fill(255); ellipse( user.x,user.y,20,20);
if(v!=null) user.add(v);
}
void mouseDragged(){
user.x=mouseX;
user.y=mouseY;
}
void mouseReleased(){
PVector diff = PVector.sub(Y,user);
v =diff.div(10);
}

♥會印出東西
♥程式碼-
void setup() {

Serial.begin(9600);
}
void loop() {
int x = analogRead(A0);
int y = analogRead(A1);
int sw = digitalRead(2);
Serial.write(x);
Serial.write('+');
Serial.write(y);
Serial.write('+');
Serial.write(sw);
Serial.write(' ');
delay(20);
}
