___Week02___
1. mousePressed
程式碼:
void setup()
{
size(500,500);
}
void draw()
{
if(mousePressed) background(255,0,0);
else background(0,255,0);
}
**點視窗會變紅色**
2. mousePressed 配合 line(mouseX,mouseY,0,0) 畫線///\\\\
程式碼:
void setup()
{
size(500,500);
}
void draw()
{
if(mousePressed) line(mouseX,mouseY,0,0);
}
3.利用line(mouseX,mouseY, pmouseX,pmouseY)來畫出小畫家的線
生出一隻小恐龍(?
程式碼:
void setup()
{
size(500,500);
}
void draw()
{
if(mousePressed) line(mouseX,mouseY,pmouseX,pmouseY);
}
**pmouse前一個滑鼠位置**
4.利用if(mouseX的範圍)及if(mouseY的範圍)來改stroke顏色
void setup()
{
size(500,500);
rect(0,0,100,100); //畫方塊
}
void draw()
{
if(mousePressed)
{
if(mouseX<100)
{
if(mouseY<100) stroke(255,0,0); //紅色
else if(mouseY<200) stroke(0,255,0); //綠色
}else line(mouseX,mouseY,pmouseX,pmouseY);
}
}
**按框框改顏色**
5.利用strokeWeight()改粗細
程式碼:
void setup()
{
size(500,500);
rect(0,0,100,100);ellipse(50,50,8,8);//紅色
rect(0,100,100,100);ellipse(50,150,4,4);//綠色
}
void draw()
{
if(mousePressed)
{
if(mouseX<100)
{
if(mouseY<100) strokeWeight(8); //粗
else if(mouseY<200) strokeWeight(4); //中
}else line(mouseX,mouseY,pmouseX,pmouseY);
}
}
**按框框改粗細**
**stroke 改顏色 strokeWeight 改粗細**
6.畫出很多個筆觸大小的框框
程式碼:
void setup()
{
size(500,500);
rect(0,50,50,50);ellipse(25,25+ 50,1,1);
rect(0,100,50,50);ellipse(25,25+100,2,2);
rect(0,150,50,50);ellipse(25,25+150,3,3);
rect(0,200,50,50);ellipse(25,25+200,4,4);
rect(0,250,50,50);ellipse(25,25+250,5,5);
rect(0,300,50,50);ellipse(25,25+300,6,6);
rect(0,350,50,50);ellipse(25,25+350,7,7);
rect(0,400,50,50);ellipse(25,25+400,8,8);
}
void draw()
{
if(mousePressed)
{
if(mouseX<50)
{
if(mouseY>1*50 && mouseY<1*50+50) strokeWeight(1);
if(mouseY>2*50 && mouseY<2*50+50) strokeWeight(2);
if(mouseY>3*50 && mouseY<3*50+50) strokeWeight(3);
if(mouseY>4*50 && mouseY<4*50+50) strokeWeight(4);
if(mouseY>5*50 && mouseY<5*50+50) strokeWeight(5);
if(mouseY>6*50 && mouseY<6*50+50) strokeWeight(6);
if(mouseY>7*50 && mouseY<7*50+50) strokeWeight(7);
if(mouseY>8*50 && mouseY<8*50+50) strokeWeight(8);
}else line(mouseX,mouseY,pmouseX,pmouseY);
}
}
7.改用fill()來畫彩色格子,利用stroke()來換畫筆的色彩,一樣是大量重覆的程式,做出來
Blue Monday需要一點彩色雲~~🌈☁☁☁☁☁☁（雖然有點像水餃皮．．．．）
程式碼:
void setup()
{
size(500,500);
fill(#FF2403);rect(0,50,50,50);
fill(#FAA508);rect(0,100,50,50);
fill(#F8FC05);rect(0,150,50,50);
fill(#5FFC05);rect(0,200,50,50);
fill(#05FCEE);rect(0,250,50,50);
fill(#0555FC);rect(0,300,50,50);
fill(#A505FC);rect(0,350,50,50);
fill(#FC05F1);rect(0,400,50,50);
}
void draw()
{
if(mousePressed)
{
if(mouseX<50)
{
if(mouseY>1*50 && mouseY<1*50+50) stroke(#FF2403);
if(mouseY>2*50 && mouseY<2*50+50) stroke(#FAA508);
if(mouseY>3*50 && mouseY<3*50+50) stroke(#F8FC05);
if(mouseY>4*50 && mouseY<4*50+50) stroke(#5FFC05);
if(mouseY>5*50 && mouseY<5*50+50) stroke(#05FCEE);
if(mouseY>6*50 && mouseY<6*50+50) stroke(#0555FC);
if(mouseY>7*50 && mouseY<7*50+50) stroke(#A505FC);
if(mouseY>8*50 && mouseY<8*50+50) stroke(#FC05F1);
}else line(mouseX,mouseY,pmouseX,pmouseY);
}
}
8. 粗細格子 兼 彩色格子 一起出現！
程式碼:
void setup()
{
size(500,500);
rect(0,50,50,50);ellipse(25,25+ 50,1,1);
rect(0,100,50,50);ellipse(25,25+100,2,2);
rect(0,150,50,50);ellipse(25,25+150,3,3);
rect(0,200,50,50);ellipse(25,25+200,4,4);
rect(0,250,50,50);ellipse(25,25+250,5,5);
rect(0,300,50,50);ellipse(25,25+300,6,6);
rect(0,350,50,50);ellipse(25,25+350,7,7);
rect(0,400,50,50);ellipse(25,25+400,8,8);
fill(#FF2403);rect(450,50,50,50);
fill(#FAA508);rect(450,100,50,50);
fill(#F8FC05);rect(450,150,50,50);
fill(#5FFC05);rect(450,200,50,50);
fill(#05FCEE);rect(450,250,50,50);
fill(#0555FC);rect(450,300,50,50);
fill(#A505FC);rect(450,350,50,50);
fill(#FC05F1);rect(450,400,50,50);
}
void draw()
{
if(mousePressed)
{
if(mouseX<50)
{
if(mouseY>1*50 && mouseY<1*50+50) strokeWeight(1);
if(mouseY>2*50 && mouseY<2*50+50) strokeWeight(2);
if(mouseY>3*50 && mouseY<3*50+50) strokeWeight(3);
if(mouseY>4*50 && mouseY<4*50+50) strokeWeight(4);
if(mouseY>5*50 && mouseY<5*50+50) strokeWeight(5);
if(mouseY>6*50 && mouseY<6*50+50) strokeWeight(6);
if(mouseY>7*50 && mouseY<7*50+50) strokeWeight(7);
if(mouseY>8*50 && mouseY<8*50+50) strokeWeight(8);
}else if(mouseX>450)
{
if(mouseY>1*50 && mouseY<1*50+50) stroke(#FF2403);
if(mouseY>2*50 && mouseY<2*50+50) stroke(#FAA508);
if(mouseY>3*50 && mouseY<3*50+50) stroke(#F8FC05);
if(mouseY>4*50 && mouseY<4*50+50) stroke(#5FFC05);
if(mouseY>5*50 && mouseY<5*50+50) stroke(#05FCEE);
if(mouseY>6*50 && mouseY<6*50+50) stroke(#0555FC);
if(mouseY>7*50 && mouseY<7*50+50) stroke(#A505FC);
if(mouseY>8*50 && mouseY<8*50+50) stroke(#FC05F1);
}else line(mouseX,mouseY,pmouseX,pmouseY);
}
}
