1-1.動者恆動 靜者恆靜
void setup(){
size(500,500);
}
int x=250,y=250;
void draw(){
ellipse(x,y,10,10);
x=x+1;
y=y-1;
}
1-2. 撞到牆會反彈
void setup(){
size(500,500);
}
float x=250,y=250;
float vx=1.0,vy=-0.5;
void draw(){
ellipse(x,y,10,10);
x=x+vx;
y=y+vy;
if(x>500) vx=-vx;
if(y<0) vy=-vy;
}
1-3. 板子反彈
void setup(){
size(500,500);
}
float x=250,y=250;
float vx=5.0,vy=-0.5;
void draw(){
background(#FFFFF2);
int boardX=mouseX;
rect(boardX,470,100,20);
ellipse(x,y,10,10);
x=x+vx;
y=y+vy;
if(x>500) vx=-vx;
if(y<0) vy=-vy;
if(x<0) vx=-vx;
if(y>470 && x>boardX && x<boardX+100) vy=-vy;
}
2-1.按左鍵板子會變大，反彈速度會跟著滑鼠移動的速度
void setup(){
size(500,500);
}
float x=250,y=250;
float vx=5.0,vy=-0.5;
float boardX,boardY=470,boardW=100,boardH=20;
void draw(){
boardX=mouseX-boardW/2;
background(#FFFFF2);
rect(boardX,boardY,boardW,boardH);
ellipse(x,y,10,10);
x=x+vx;
y=y+vy;
if(x>500) vx=-vx;
if(y<0) vy=-vy;
if(x<0) vx=-vx;
if((y>boardY && y<boardY+boardH) && (x>boardX && x<boardX+boardW)){
vy=-vy;
vx += (mouseX-pmouseX)/2;
}
if(mousePressed && mouseButton==LEFT) boardW *= 1.01;
if(mousePressed && mouseButton==RIGHT) boardW *= 0.99;
}
2-2.圍棋
void setup(){
size(500,500);
}
void draw(){
for(int x=50;x<=450;x+=50){
for(int y=50;y<=450;y+=50){
ellipse(x,y,50,50);
}
}
}
2-3.改良版
void setup(){
size(500,500);
}
int [][] go={
{0,0,0,0,0,0,0,0,1},
{0,0,0,0,0,0,0,0,1},
{0,1,0,0,0,0,0,0,1},
{0,0,0,0,0,0,1,0,1},
{0,0,0,0,0,0,0,0,1},
{0,0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0,0},
};
void draw(){
for(int i=0;i<9;i++){
for(int j=0;j<9;j++){
if(go[i][j]==1) fill(0);
else fill(255);
ellipse(50+j*50,50+i*50,50,50);
}
}
}
3-1.圍棋二改
void setup(){
size(500,500);
}
int [][] go={
{0,0,0,0,0,0,0,0,1},
{0,0,0,0,0,0,0,0,1},
{0,1,0,0,0,0,0,0,1},
{0,0,0,0,0,0,1,0,1},
{0,0,0,0,0,0,0,0,1},
{0,0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0,0},
};
void draw(){
background(246,194,108);
for(int i=1;i<=9;i++){
line(50,50*i,450,50*i);
line(50*i,50,50*i,450);
}
for(int i=0;i<9;i++){
for(int j=0;j<9;j++){
if(go[i][j]==1){
fill(0);
ellipse(50+j*50,50+i*50,40,40);
}else if(go[i][j]==2){
fill(255);
ellipse(50+j*50,50+i*50,40,40);
}
}
}
}
3-3.可出現白棋
void setup(){
size(500,500);
}
int [][] go={
{0,0,0,0,0,0,0,0,1},
{0,0,0,0,0,0,0,0,1},
{0,1,0,0,0,0,0,0,1},
{0,0,0,0,0,0,1,0,1},
{0,0,0,0,0,0,0,0,1},
{0,0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0,0},
};
int N=0;
void mousePressed(){
int j=(mouseX-25)/50;
int i=(mouseY-25)/50;
go[i][j] = (N%2==0) ? 1:2;
N++;
}
void draw(){
background(246,194,108);
for(int i=1;i<=9;i++){
line(50,50*i,450,50*i);
line(50*i,50,50*i,450);
}
for(int i=0;i<9;i++){
for(int j=0;j<9;j++){
if(go[i][j]==1){
fill(0);
ellipse(50+j*50,50+i*50,40,40);
}else if(go[i][j]==2){
fill(255);
ellipse(50+j*50,50+i*50,40,40);
}
}
}
}
