0.音檔按下去換stage
1.按下去換音樂
import processing.sound.*;
SoundFile sound1, sound2, sound3;
void setup(){
size(400, 300);
textSize(50);
fill(255,0,0);
sound1 = new SoundFile(this, "In Game Music.mp3");
sound2 = new SoundFile(this, "Intro Song_Final.mp3");
sound1.play();
}
int stage = 1; ///1,2,3
void draw(){
background(255);
if(stage==1){
text("stage1", 100, 100);
}else if(stage==2){
text("stage2", 100, 100);
}
}
void mousePressed(){
if(stage==1){
stage=2;
sound1.stop();
sound2.play();
}else if(stage==2){
stage=1;
sound2.stop();
sound1.play();
}
}
void setup(){
size(400, 300);
}
int stage = 1; //1:start, 2:playing
void draw(){
background(255,255,0);
fill(255,0,0);
textSize(80);
if(stage==1){
text("stage 1", 100, 100);
}else if(stage==2){
text("stage 2", 100, 100);
}
}
void mousePressed(){
if(stage==1) stage=2;
else if(stage==2) stage=1;
}
///目標: 有個水果可以飛起來!!
///按按鍵,可以把它消掉
void setup() {
size(400, 300);
}
float fruitX = 200, fruitY=300; ///水果位置
float fruitVX = 2, fruitVY=-13; ///水果速度
boolean flying = true;
void draw() {
background(255, 255, 0);
ellipse(fruitX, fruitY, 50, 50);
if (flying) { ///如果還在飛,水果位置改變
fruitX+=fruitVX;
fruitY+=fruitVY;
fruitVY+=0.98/3; ///重力加速度
}
}
void keyPressed() {
flying=false;
fruitReset(); ///準備新的水果
}
void fruitReset() {
fruitX=random(100, 300);
fruitY=300; ///固定高度
fruitVX=random(-2, +2);
fruitVY=-13;
flying=true;
}
4.用class 物件導向觀念改3.
class Fruit{
float x, y, vx, vy;
boolean flying;
PApplet sketch; ///為了讓random可以在class裡用
Fruit(PApplet _sketch){ //建構子: 一開始要做的事
sketch = _sketch;
reset();
}
void reset(){
x = sketch.random(100.0, 300.0);
y = 300;
vx = sketch.random(-2, +2);
vy = -13;
flying = true;
}
void update(){
x += vx;
y += vy;
vy += 0.98/3; //重力加速度
}
}
Fruit fruit;
void setup(){
size(400, 300);
fruit = new Fruit(this);
}
void draw(){
background(255, 255, 0);
ellipse(fruit.x, fruit.y, 50, 50);
fruit.update();
}
void keyPressed(){
fruit.reset();
}
5.分頁並完成能切水果
Fruit []fruits;
void setup(){
size(400, 300);
fruits = new Fruit[3];
for(int i=0;i<3;i++){
fruits[i] = new Fruit(this);
}
}
void draw(){
background(255, 255, 0);
for(int i=0;i<3;i++){
fill(255); ellipse(fruits[i].x, fruits[i].y, 50, 50);
textSize(30);
textAlign(CENTER,CENTER);
fill(0); text(fruits[i].c, fruits[i].x, fruits[i].y);
fruits[i].update();
}
}
void keyPressed(){
for(int i=0;i<3;i++){
if(keyCode == fruits[i].c){
fruits[i].reset();
}
}
}
