今天第一個程式:
第一個:
PImage img=loadImage("TWI_IR1_CR_800-2024-10-02-08-00.jpg"); size(800,800); background(img);
第二個:
int N=299; PImage[]imgs=new PImage[299]; void setup() { size(800, 800); String [] filenames=loadStrings("list.txt"); for (int i=0; i<N; i++) { imgs[i]=loadImage(filenames[i]); } } void draw() { int i=frameCount%N; background(imgs[i]); }第三個(加入上禮拜的縮放程式):PImage img; void setup() { size(500, 500); img=loadImage("LCC_VIS_TRGB_2750-2024-10-02-07-40.jpg"); } float s=0.4, x=0, y=0; float realX=0, realY=0; void draw() { background(#92C2F5); translate(x, y); scale(s); image(img, 0, 0); } void mouseDragged() { x+=mouseX-pmouseX; y+=mouseY-pmouseY; } void mouseWheel(MouseEvent e) { realX=(mouseX-x)/s; realY=(mouseY-y)/s; float oldS=s; if (e.getCount()>0)s*=0.9; else s*=1.1; x = x + realX*oldS - realX*s; y = y + realY*oldS - realY*s; }第四個(滑鼠可以按著拉球):void setup() { size(400, 600); } float x=200, y=300; void draw() { background(255); line(200, 100, x, y); ellipse(x, y, 30, 30); } void mouseDragged() { x=mouseX; y=mouseY; }
第五個:void setup() { size(400, 600); } float x=200, y=300; void draw() { background(255); stroke(0); line(200, 100, x, y); ellipse(x, y, 30, 30); stroke(255, 0, 0); line(x, y, x, y+100); PVector d= new PVector(x-200, y-100).normalize(); PVector d2=new PVector(0,1); float g=PVector.dot(d,d2); d.mult(100*g); stroke(0, 255, 0); line(x, y, x+d.x, y+d.y); } void mouseDragged() { x=mouseX; y=mouseY; }
第六個(認識PVector):void setup() { size(400, 600); c=new PVector(200, 100); p=new PVector(200, 130); } PVector c, p; void draw() { background(255); ellipse(c.x,c.y,10,10); ellipse(p.x,p.y,10,10); }
第七個(利用PVector算出藍色的線):void setup() { size(400, 600); } float x=200, y=300; void draw() { background(255); stroke(0); line(200, 100, x, y); ellipse(x, y, 30, 30); stroke(255, 0, 0); line(x, y, x, y+100); PVector d= new PVector(x-200, y-100).normalize(); PVector d2=new PVector(0,1); float g=PVector.dot(d,d2); d.mult(100*g); stroke(0, 255, 0); line(x, y, x+d.x, y+d.y); PVector N=new PVector(d.y,-d.x).normalize(); N.mult(100*sin(acos(g))); stroke(0,0,255); line(x,y,x+N.x,y+N.y); } void mouseDragged() { x=mouseX; y=mouseY; }第八個(因為程式還沒寫好,所以球會一直掉下去):void setup() { size(400, 600); } float x=200, y=300; void draw() { background(255); stroke(0); line(200, 100, x, y); ellipse(x, y, 30, 30); stroke(255, 0, 0); line(x, y, x, y+100); PVector d= new PVector(x-200, y-100).normalize(); PVector d2=new PVector(0,1); float g=PVector.dot(d,d2); d.mult(100*g); stroke(0, 255, 0); line(x, y, x+d.x, y+d.y); PVector N=PVector.sub(d2.mult(100),d);//PVector N=//new PVector(d.y,-d.x).normalize(); //N.mult(100*sin(acos(g))); stroke(0,0,255); line(x,y,x+N.x,y+N.y); v.x+=N.x/1000;//x+=N.x/100; v.y+=N.y/1000;//y+=N.y/100; x+=v.x; y+=v.y; } PVector v=new PVector(); void mouseDragged() { x=mouseX; y=mouseY; }快捷鍵:ctrl+R 執行
