2.將week02的程式碼複製
3.期中作品想做跳躍障礙物的小遊戲

只能先畫出2D的線

在3D中能邊旋轉邊畫線

調色盤
可以偵測左右手並畫出橢圓及長方形
import de.voidplus.leapmotion.*;//LeapMotion標頭檔
LeapMotion leap;
void setup() {
size(640, 480, P3D);
leap = new LeapMotion(this);
}
void draw(){
background(255);
for (Hand hand : leap.getHands ()) {
PVector pos= hand.getPosition();
if( hand.isLeft() ){
ellipse(pos.x, pos.y, 200, 100);
}else if( hand.isRight() ){
rect(pos.x, pos.y, 10, 100);
}
}
}
長條碰到黃色橢圓區塊會變成黃色
import de.voidplus.leapmotion.*;//LeapMotion標頭檔

PVector leftPos;
