用畫出圓點
size(500,500);
for(int angle=0;angle<360;angle+=30){
float angle2 = radians(angle); ///弧度
float x = 100+cos(angle2)*50;
float y = 100+sin(angle2)*50;
ellipse(x,y,2,2); //劃出點 大小(2,2)
}
利用三角函數畫三角形
程式碼:
size(500,500);
beginShape();
for(int angle=0;angle<360;angle+=120){ ///加120度為三角形
float angle2 = radians(angle);
float x = 100+cos(angle2)*50;
float y = 100+sin(angle2)*50;
vertex(x,y); ///點
}
endShape(CLOSE);
滑鼠旋轉游標，三角形跟著轉
程式碼:
void setup(){
size(500,500);
}
void draw(){
//background(255);//清畫面
beginShape();
for(int angle=0;angle<360;angle+=120){
float angle2 = radians(angle+mouseX);
float x = 100+cos(angle2)*50;
float y = 100+sin(angle2)*50;
vertex(x,y);
}
endShape(CLOSE);
}
三角形跟著滑鼠移動
程式碼:
void setup(){
size(500,500);
}
void draw(){
///background(255);//清畫面
beginShape();
for(int angle=0;angle<360;angle+=120){
float angle2 = radians(angle+mouseX);
float x = mouseX+cos(angle2)*50;
float y = mouseY+sin(angle2)*50;
vertex(x,y);
}
endShape(CLOSE);
}
三角形自己旋轉，滑鼠可以移動它
*1sec = 60frame
程式碼:
void setup(){
size(500,500);
}
void draw(){
///background(255);//清畫面
beginShape();
for(int angle=0;angle<360;angle+=120){
float angle2 = radians(angle+frameCount); ///frameCount=螢幕每秒會跑60次
float x = mouseX+cos(angle2)*100;
float y = mouseY+sin(angle2)*100;
vertex(x,y);
}
endShape(CLOSE);
}
接水果遊戲
程式碼:
float [] fruitX=new float[10];
float [] fruitY=new float[10];
float kidX=150,kidY=450;
int score=0;
void setup(){
size(500,500);
for(int i=0;i<10;i++){
fruitX[i] = random(50,450);
fruitY[i] = -i*100;
}
}
void draw(){
background(255);

score+=10;///接住了就加分

}else{
