🔸嗨，今天上課先畫個圍棋底圖
void setup()
{
size(500,500);
}
void draw()
{
background(253,236,180);
line(50,50,50,450);
line(100,50,100,450);
line(150,50,150,450);
line(200,50,200,450);
}
🔹用迴圈改一下
void setup()
{
size(500,500);
}
void draw()
{
background(253,236,180);
for(int i=50;i<=500;i+=50)
{
line(i,50,i,450);
}
}
🔸加上橫線
void setup()
{
size(500,500);
}
void draw()
{
background(253,236,180);
for(int i=50;i<=500;i+=50)
{
line(i,50,i,450);
line(50,i,450,i);
}
}
🔹05用陣列
int [][]go={
{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},
{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},
{0,0,0,0,0,0,0,0,0}};
}
void setup()
{
size(500,500);
}
void draw()
{
background(253,236,180);
for(int i=50;i<=500;i+=50)
{
line(i,50,i,450);
line(50,i,450,i);
}
}
🔸畫紅灰的格子，1是紅格子，0是灰格子
j是x方向，i是y方向
int [][]c={
{1,0,0},
{1,0,0},
{1,0,0}};
void setup()
{
size(300,300);
}
void draw()
{
for(int i=0;i<3;i++)
{
for(int j=0;j<3;j++)
{
if(c[i][j]==0)fill(128);
else fill(255,0,0);
rect(j*100,i*100,100,100);
}
}
}
🔹用陣列的方式下棋子，按照座標打1可以下白棋
int [][]go={
{0,0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0,0},
{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},
{0,0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0,0}};
void setup()
{
size(500,500);
}
void draw()
{
background(253,236,180);
for(int i=0;i<=9;i++)
{
line(50+50*i,50,50+50*i,450);
line(50,50+50*i,450,50+50*i);
}
for(int i=0;i<9;i++)
{
for(int j=0;j<9;j++)
{
if(go[i][j]==1)
{
int x=50+50*j,y=50+50*i;
fill(255);
ellipse(x,y,40,40);
}
}
}
}
🔸讓棋子可以透過滑鼠點擊增加，x、y與j、i利用移項變號
int [][]go={
{0,0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0,0},
{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},
{0,0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0,0}};
void setup()
{
size(500,500);
}
void draw()
{
background(253,236,180);
for(int i=0;i<=9;i++)
{
line(50+50*i,50,50+50*i,450);
line(50,50+50*i,450,50+50*i);
}
for(int i=0;i<9;i++)
{
for(int j=0;j<9;j++)
{
if(go[i][j]==1)
{
int x=50+50*j,y=50+50*i;
fill(255);
ellipse(x,y,40,40);
}
}
}
}
void mousePressed()
{
int j=(mouseX-50)/50;
int i=(mouseY-50)/50;
go[i][j]=1;
}
🔹改為25會更增加辨識度
void mousePressed()
{
int j=(mouseX-25)/50;
int i=(mouseY-25)/50;
go[i][j]=1;
}
🔸左鍵白右鍵黑中鍵消除棋子
int [][]go={
{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},
{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},
{0,0,0,0,0,0,0,0,0}};
void setup()
{
size(500,500);
}
void draw()
{
background(253,236,180);
for(int i=0;i<=9;i++)
{
line(50+50*i,50,50+50*i,450);
line(50,50+50*i,450,50+50*i);
}
for(int i=0;i<9;i++)
{
for(int j=0;j<9;j++)
{
if(go[i][j]==1)
{
int x=50+50*j,y=50+50*i;
fill(255);ellipse(x,y,40,40);
}
else if(go[i][j]==2)
{
int x=50+50*j,y=50+50*i;
fill(0);ellipse(x,y,40,40);
}
}
}
}
void mousePressed()
{
int j=(mouseX-25)/50;
int i=(mouseY-25)/50;
if(mouseButton==LEFT)go[i][j]=1;
if(mouseButton==RIGHT)go[i][j]=2;
if(mouseButton==CENTER)go[i][j]=0;
}
🔹用三角函數畫出一個圓
void setup()
{
size(500,500);
}
void draw()
{
for(float a=0;a<360;a++)
{
float x =250+250*cos(radians(a));
float y =250+250*sin(radians(a));
ellipse(x,y,4,4);
}
}
🔸a+=10
🔹改用滑鼠座標來畫
void setup()
{
size(500,500);
}
void draw()
{
background(128);
for(float a=0;a<360;a+=1)
{
float x =250+mouseX*cos(radians(a));
float y =250+mouseY*sin(radians(a));
ellipse(x,y,mouseX,mouseY);
}
}
🔸變換顏色的圓圈
void setup()
{
size (500,500);
}
float w=30;
float r=0,g=255,b=0;
void draw()
{
stroke(r,g,b);noFill();
r+=random(3);if(r>255)r=0;
g+=random(3);if(g>255)r=0;
b+=random(3);if(b>255)r=0;
ellipse(mouseX,mouseY,w,w);
w+=0.5;
if(w>100)w=30;
}
