Step01 小畫家
void setup(){ size(400,400); background(255); } void draw(){ if(mousePressed) line(mouseX,mouseY,pmouseX,pmouseY); } void mouseReleased(){ background(255); }
做出圓形往中心點移動
void setup(){ size(400,400); background(255); } float ghostX=400,ghostY=20; void draw(){ ellipse(200,200,15,15); if(mousePressed) line(mouseX,mouseY,pmouseX,pmouseY); ellipse(ghostX,ghostY,15,15); float dx=200-ghostX,dy=200-ghostY,len=sqrt(dx*dx+dy*dy); ghostX +=dx/len/3; ghostY +=dy/len/3; } void mouseReleased(){ background(255); }
ArrayList<PVector> pt=new ArrayList<PVector>(); void setup(){ size(400,400); background(255); } float ghostX=400,ghostY=20; void mouseDragged(){ pt.add(new PVector(mouseX,mouseY)); } void draw(){ background(255); ellipse(200,200,15,15); for(int i=0;i<pt.size();i++){ PVector p=pt.get(i); ellipse(p.x,p.y,3,3); } //if(mousePressed) line(mouseX,mouseY,pmouseX,pmouseY); ellipse(ghostX,ghostY,15,15); float dx=200-ghostX,dy=200-ghostY,len=sqrt(dx*dx+dy*dy); ghostX +=dx/len/3; ghostY +=dy/len/3; } void mouseReleased(){ background(255); }
放開M1,畫過的現就會消失
ArrayList<PVector> pt=new ArrayList<PVector>(); void setup(){ size(400,400); background(255); } float ghostX=400,ghostY=20; void mouseDragged(){ pt.add(new PVector(mouseX,mouseY)); } void draw(){ background(255); ellipse(200,200,15,15); for(int i=0;i<pt.size();i++){ PVector p=pt.get(i); ellipse(p.x,p.y,3,3); } //if(mousePressed) line(mouseX,mouseY,pmouseX,pmouseY); ellipse(ghostX,ghostY,15,15); float dx=200-ghostX,dy=200-ghostY,len=sqrt(dx*dx+dy*dy); ghostX +=dx/len/3; ghostY +=dy/len/3; } void mouseReleased(){ //background(255); for(int i=pt.size()-1;i>=0;i--){ pt.remove(i); } }
Step02
畫橫的線會變成紅色的
ArrayList<PVector> pt=new ArrayList<PVector>(); void setup(){ size(400,400); background(255); } float ghostX=400,ghostY=20; void mouseDragged(){ pt.add(new PVector(mouseX,mouseY)); } void draw(){ background(255); ellipse(200,200,15,15); ellipse(ghostX,ghostY,15,15); strokeWeight(4); float dpx=0,dpy=0; for(int i=0;i<pt.size()-1;i++){ PVector p=pt.get(i),p2=pt.get(i+1); dpx += abs(p2.x-p.x); dpy += abs(p2.y-p.y); //ellipse(p.x,p.y,3,3); } if(dpx>100&&dpy<40) stroke(255,0,0); else stroke(0); //if(mousePressed) line(mouseX,mouseY,pmouseX,pmouseY); for(int i=0;i<pt.size()-1;i++){ PVector p=pt.get(i),p2 = pt.get(i+1); line(p.x,p.y,p2.x,p2.y); } float dx=200-ghostX,dy=200-ghostY,len=sqrt(dx*dx+dy*dy); ghostX +=dx/len/3; ghostY +=dy/len/3; } void mouseReleased(){ //background(255); for(int i=pt.size()-1;i>=0;i--){ pt.remove(i); } }
畫直的線會變藍色的
ArrayList<PVector> pt=new ArrayList<PVector>(); void setup(){ size(400,400); background(255); } float ghostX=400,ghostY=20; void mouseDragged(){ pt.add(new PVector(mouseX,mouseY)); } void draw(){ background(255); strokeWeight(1); stroke(0); ellipse(200,200,15,15); stroke(0); ellipse(ghostX,ghostY,15,15); strokeWeight(4); float dpx=0,dpy=0; for(int i=0;i<pt.size()-1;i++){ PVector p=pt.get(i),p2=pt.get(i+1); dpx += abs(p2.x-p.x); dpy += abs(p2.y-p.y); //ellipse(p.x,p.y,3,3); } if(dpx>100&&dpy<40) stroke(255,0,0); else if(dpx<40&&dpy>100) stroke(0,0,255); else stroke(0); //if(mousePressed) line(mouseX,mouseY,pmouseX,pmouseY); for(int i=0;i<pt.size()-1;i++){ PVector p=pt.get(i),p2 = pt.get(i+1); line(p.x,p.y,p2.x,p2.y); } float dx=200-ghostX,dy=200-ghostY,len=sqrt(dx*dx+dy*dy); ghostX +=dx/len/3; ghostY +=dy/len/3; } void mouseReleased(){ //background(255); for(int i=pt.size()-1;i>=0;i--){ pt.remove(i); } }
往右下話會變綠色
ArrayList<PVector> pt=new ArrayList<PVector>(); void setup(){ size(400,400); background(255); } float ghostX=400,ghostY=20; void mouseDragged(){ pt.add(new PVector(mouseX,mouseY)); } void draw(){ background(255); strokeWeight(1); stroke(0); ellipse(200,200,15,15); stroke(0); ellipse(ghostX,ghostY,15,15); strokeWeight(4); float dpx=0,dpy=0; int rightdown=0; for(int i=0;i<pt.size()-1;i++){ PVector p=pt.get(i),p2=pt.get(i+1); dpx += abs(p2.x-p.x); dpy += abs(p2.y-p.y); //ellipse(p.x,p.y,3,3); if(p2.x-p.x>0&&p2.y-p.y>0) rightdown++; } if(dpx>100&&dpy<40) stroke(255,0,0); else if(dpx<40&&dpy>100) stroke(0,0,255); else if(rightdown>30) stroke(0,255,0); else stroke(0); //if(mousePressed) line(mouseX,mouseY,pmouseX,pmouseY); for(int i=0;i<pt.size()-1;i++){ PVector p=pt.get(i),p2 = pt.get(i+1); line(p.x,p.y,p2.x,p2.y); } float dx=200-ghostX,dy=200-ghostY,len=sqrt(dx*dx+dy*dy); ghostX +=dx/len/3; ghostY +=dy/len/3; } void mouseReleased(){ //background(255); for(int i=pt.size()-1;i>=0;i--){ pt.remove(i); } }
Step03
可以判斷打勾ˇ的形狀
ArrayList<PVector> pt=new ArrayList<PVector>(); void setup(){ size(400,400); background(255); } float ghostX=400,ghostY=20; void mouseDragged(){ pt.add(new PVector(mouseX,mouseY)); } void draw(){ background(255); strokeWeight(1); stroke(0); ellipse(200,200,15,15); stroke(0); ellipse(ghostX,ghostY,15,15); strokeWeight(4); float dpx=0,dpy=0; float rightdown=0,rightup=0; boolean green_part1=false,green_ok=false; for(int i=0;i<pt.size()-1;i++){ PVector p=pt.get(i),p2=pt.get(i+1); dpx += abs(p2.x-p.x); dpy += abs(p2.y-p.y); if(p2.x-p.x>0&&p2.y-p.y>0) rightdown+=sqrt(dpx*dpx+dpy*dpy); if(p2.x-p.x>0&&p2.y-p.y>0) rightup+=sqrt(dpx*dpx+dpy*dpy); ellipse(p.x,p.y,10,10); if(green_part1==false&& rightdown>150) green_part1=true; else if(green_part1==true&&rightup>150) green_ok=true; } println(rightdown); if(dpx>100&&dpy<40) stroke(255,0,0); else if(dpx<40&&dpy>100) stroke(0,0,255); else if(green_ok) stroke(0,255,0); else stroke(0); //if(mousePressed) line(mouseX,mouseY,pmouseX,pmouseY); for(int i=0;i<pt.size()-1;i++){ PVector p=pt.get(i),p2 = pt.get(i+1); line(p.x,p.y,p2.x,p2.y); } float dx=200-ghostX,dy=200-ghostY,len=sqrt(dx*dx+dy*dy); ghostX +=dx/len/3; ghostY +=dy/len/3; } void mouseReleased(){ //background(255); for(int i=pt.size()-1;i>=0;i--){ pt.remove(i); } }
把右下的線變成深綠色
ArrayList<PVector> pt=new ArrayList<PVector> (); void setup(){ size(400,400); background(255); } float ghostX=400,ghostY=20; void mouseDragged(){ pt.add(new PVector(mouseX,mouseY)); } void draw(){ background(255); strokeWeight(1); stroke(0) ; ellipse(200,200,15,15); stroke(0) ;ellipse(ghostX,ghostY,15,15); strokeWeight(4); float dpx=0,dpy=0; float rightdown=0,green_rightup=0; boolean green_part1=false,green_ok=false; /// if(mousePressed) line(mouseX,mouseY,pmouseX,pmouseY); for(int i=0;i<pt.size()-1;i++){ PVector p=pt.get(i),p2=pt.get(i+1); dpx+=abs(p2.x-p.x); dpy+=abs(p2.y-p.y); if(p2.x-p.x >0 && p2.y-p.y>0) rightdown+=sqrt(dpx*dpx+dpy*dpy); if( green_part1 && p2.x-p.x>0 && p2.y-p.y<0) green_rightup+=sqrt(dpx*dpx+dpy*dpy); ellipse(p.x,p.y,10,10); if(green_part1==false && rightdown>150) green_part1=true; else if(green_part1==true && green_rightup>150) green_ok=true; } println (rightdown); if(dpx>100&&dpy<40) stroke(255,0,0); else if(dpx<40 && dpy>100) stroke(0,0,255); else if(green_ok) stroke(0,255,0); else if(green_part1) stroke(0,128,0); else stroke(0); for(int i=0;i<pt.size()-1;i++){ PVector p=pt.get(i),p2=pt.get(i+1); line(p.x,p.y,p2.x,p2.y); } float dx=200-ghostX,dy=200-ghostY,len=sqrt(dx*dx+dy*dy); ghostX+=dx/len/3; ghostY+=dy/len/3; } void mouseReleased(){ for(int i=pt.size()-1;i>=0;i--){ pt.remove(i); } }
這個^符號會變成黃色
ArrayList<PVector> pt=new ArrayList<PVector> (); void setup(){ size(400,400); background(255); } float ghostX=400,ghostY=20; void mouseDragged(){ pt.add(new PVector(mouseX,mouseY)); } void draw(){ background(255); strokeWeight(1); stroke(0) ; ellipse(200,200,15,15); stroke(0) ;ellipse(ghostX,ghostY,15,15); strokeWeight(4); float dpx=0,dpy=0; float rightdown=0,green_rightup=0; float rightup=0,yellow_rightdown=0; boolean green_part1=false,green_ok=false; boolean yellow_part1=false,yellow_ok=false; /// if(mousePressed) line(mouseX,mouseY,pmouseX,pmouseY); for(int i=0;i<pt.size()-1;i++){ PVector p=pt.get(i),p2=pt.get(i+1); dpx+=abs(p2.x-p.x); dpy+=abs(p2.y-p.y); if(p2.x-p.x >0 && p2.y-p.y>0) rightdown+=sqrt(dpx*dpx+dpy*dpy); if( green_part1 && p2.x-p.x>0 && p2.y-p.y<0) green_rightup+=sqrt(dpx*dpx+dpy*dpy); if(p2.x-p.x >0 && p2.y-p.y<0) rightup+=sqrt(dpx*dpx+dpy*dpy); if( yellow_part1 && p2.x-p.x>0 && p2.y-p.y>0) yellow_rightdown+=sqrt(dpx*dpx+dpy*dpy); //ellipse(p.x,p.y,10,10); if(green_part1==false && rightdown>150) green_part1=true; else if(green_part1==true && green_rightup>150) green_ok=true; if(yellow_part1==false && rightup>150) yellow_part1=true; else if(yellow_part1==true && yellow_rightdown>150) yellow_ok=true; } println (rightdown); if(dpx>100&&dpy<40) stroke(255,0,0); else if(dpx<40 && dpy>100) stroke(0,0,255); else if(green_ok) stroke(0,255,0); //else if(green_part1) stroke(0,128,0); else if(yellow_ok) stroke(255,255,0); else stroke(0); for(int i=0;i<pt.size()-1;i++){ PVector p=pt.get(i),p2=pt.get(i+1); line(p.x,p.y,p2.x,p2.y); } float dx=200-ghostX,dy=200-ghostY,len=sqrt(dx*dx+dy*dy); ghostX+=dx/len/3; ghostY+=dy/len/3; } void mouseReleased(){ for(int i=pt.size()-1;i>=0;i--){ pt.remove(i); } }
