跟下面合在一起！
float x;
float y;
float px;
float py;
float myEasing=0.02;
void setup(){
size(960,480);
stroke(0,102);
}
void draw(){
float targetX=mouseX;
float targetY=mouseY;
x+=(targetX-x)*myEasing;
y+=(targetY-y)*myEasing;
float myWeight=dist(x,y,px,py);
strokeWeight(myWeight);
line(x,y,px,py);
px=x;
py=y;
}

把第二个setup里面的内容放到第一个里面，再删掉第二个setup就行了，draw也一样

一个程序里只能有一个setup和一个draw
你把需要的东西都放进去就可以
