1.碰撞偵測
void setup(){ size(400,400); } float x=200,y=200,vx=1,vy=1; void draw(){ ellipse(x,y,10,10); x+=vx; y+=vy; } 2.執行後有拋物線
void setup(){ size(400,400); } float x=50,y=250,vx=2,vy=-20; void draw(){ ellipse(x,y,10,10); x+=vx; y+=vy; vy+=0.98; } 3.用if判斷是否碰到地板
void setup(){ size(400,400); } float x=50,y=250,vx=2,vy=-20; void draw(){ x+=vx; y+=vy; vy+=0.98; if(y>350){ y=350; } ellipse(x,y,10,10); } 3-1
void setup(){ size(400,400); } float x=50,y=250,vx=2,vy=-20; void draw(){ x+=vx; y+=vy; vy+=0.98; if(y>350){ y=350; vy=-vy*05; } ellipse(x,y,10,10); } 4.設計背景的顏色,左右會移動
void setup(){ size(400,400); } float marioX=50,marioY=250,vx=2,vy=-20; void draw(){ background(108,137,255); marioX+=vx; fill(255,0,0); ellipse(marioX,marioY,15,25); fill(229,119,42); rect(0,260,400,150); } void keyPressed(){ if(keyCode==RIGHT) vx=2; if(keyCode==LEFT) vx=-2; } 5.按下去會停止
void setup(){ size(400,400); } float marioX=50,marioY=250,vx=0,vy=0; void draw(){ background(108,137,255); marioX+=vx; marioY+=vy; //vy+=0.98; fill(255,0,0);ellipse(marioX,marioY,10,20); fill(229,119,42);rect(0,260,400,150); } void keyPressed(){ if(keyCode==RIGHT)vx=2; if(keyCode==LEFT)vx=-2; if(keyCode==UP)vy=-20; } void keyReleased(){ if(keyCode==LEFT || keyCode==RIGHT)vx=0; }
6.
void setup(){ size(400,400); } float marioX=50,marioY=250,vx=0,vy=0; void draw(){ background(108,137,255); marioX+=vx; if(flying){ marioY+=vy; vy+=0.98; if(marioY>=250){ marioY=250;//站在地板上 flying=false;//不再飛行 } } fill(255,0,0);ellipse(marioX,marioY,10,20); fill(229,119,42);rect(0,260,400,150); } boolean flying=false; void keyPressed(){ if(keyCode==RIGHT)vx=2; if(keyCode==LEFT)vx=-2; if(keyCode==UP){ vy=-20; flying=true;//開始飛行 } } void keyReleased(){ if(keyCode==LEFT || keyCode==RIGHT)vx=0; }
7.
void setup(){ size(400,400); } float marioX=50,marioY=250,vx=0,vy=0; void draw(){ background(108,137,255); marioX+=vx; if(flying){ marioY+=vy; vy+=0.98; if(marioY>=250){ marioY=250;//站在地板上 flying=false;//不再飛行 } } fill(255,0,0);ellipse(marioX,marioY,10,20); fill(229,119,42);rect(0,260,400,150); fill(229,119,42);rect(200,150,20,20); if(hitBox(200,150,20,20)){ vy=0; marioY=150+20; } } boolean hitBox(int x,int y,int w,int h){ if(x<marioX && marioX<x+w && y<marioY && marioY<y+h)return true; else return false; } boolean flying=false; void keyPressed(){ if(keyCode==RIGHT)vx=2; if(keyCode==LEFT)vx=-2; if(keyCode==UP && flying==false){//如果沒有在飛的話,才能飛 vy=-20; flying=true;//開始飛行 } } void keyReleased(){ if(keyCode==LEFT || keyCode==RIGHT)vx=0; }
8.可以跳到方塊void setup(){ size(400,400); } float marioX=50,marioY=250,vx=0,vy=0; void draw(){ background(108,137,255); marioX+=vx; if(flying){ marioY+=vy; vy+=0.98; if(marioY>=250){ marioY=250;//站在地板上 flying=false;//不再飛行 } } fill(255,0,0);ellipse(marioX,marioY,10,20); fill(229,119,42);rect(0,260,400,150); fill(229,119,42);rect(200,150,20,20); if(hitBox(200,150,20,20)){ if(vy>0){ marioY=150-10; flying=false; }else{ vy=0; marioY=150+20+10; } } } boolean hitBox(int x,int y,int w,int h){ if(x-7<marioX && marioX<x+w+7 && y-10<marioY && marioY<y+h+10)return true; else return false; } boolean flying=false; void keyPressed(){ if(keyCode==RIGHT)vx=2; if(keyCode==LEFT)vx=-2; if(keyCode==UP && flying==false){//如果沒有在飛的話,才能飛 vy=-20; flying=true;//開始飛行 } } void keyReleased(){ if(keyCode==LEFT || keyCode==RIGHT)vx=0; } 9.讓角色離開方塊可以掉下來
void setup(){ size(400,400); } float marioX=50,marioY=250,vx=0,vy=0; void draw(){ background(108,137,255); marioX+=vx; if(flying){ marioY+=vy; vy+=0.98; if(marioY>=250){ marioY=250;//站在地板上 flying=false;//不再飛行 } } fill(255,0,0);ellipse(marioX,marioY,10,20); fill(229,119,42);rect(0,260,400,150); fill(229,119,42);rect(200,150,20,20); if(hitBox(200,150,20,20)){ if(vy>0){ marioY=150-10; flying=false; stand_box=true; }else{ vy=0; marioY=150+20+10; } } if(stand_box==true && flying==false){ stand_box=false; flying=true; vy=0; } } boolean leaveBox(int x,int y,int w,int h){ if(x-7>marioX && marioX>x+w+7)return true; else return false; } boolean hitBox(int x,int y,int w,int h){ if(x-7<marioX && marioX<x+w+7 && y-10<marioY && marioY<y+h+10)return true; else return false; } boolean flying=false,stand_box=false; void keyPressed(){ if(keyCode==RIGHT)vx=2; if(keyCode==LEFT)vx=-2; if(keyCode==UP && flying==false){//如果沒有在飛的話,才能飛 vy=-20; flying=true;//開始飛行 } } void keyReleased(){ if(keyCode==LEFT || keyCode==RIGHT)vx=0; }
