Question 1:In your own words, please explain the difference between having your for loop from Step 2 in setup() as opposed to in draw().
Having the for loop in setup() would only draw the image once. But if I put the for loop in draw(), it would draw continuously.
Question 2:What is the benefit of using arrays? How might you use arrays in a potential project?
By using arrays, we could put same type variables under one category instead of repeating them separately for several time. I think I might use arrays for a project in which I want several shapes to be presented simultaneously at different locations with different speeds.
int rad = 60;
float[] ballx=new float [100];
float[] bally=new float [100];
float[] ballxspeed=new float [100];
float[] ballyspeed=new float [100];
void setup()
{
size(640, 360);
for(int i=0;i<ballx.length;i++){
ballx[i]=random(width);
bally[i]=random(height);
ballxspeed[i]=random(20);
ballyspeed[i]=random(0.1);
}
}
void draw()
{
background(255);
for(int i=0;i<ballx.length;i++){
strokeWeight(1);
stroke(60);
int c = color( 90,0,150,random(0,255));
fill(c);
ellipse(ballx[i], bally[i], rad, rad);
rect(ballx[i], bally[i],10,10);
triangle(ballx[i],bally[i],ballx[i]+10,bally[i],0,0);
ballx[i] = ballx[i] + ballxspeed[i] ;
bally[i] = bally[i] + ballyspeed[i] ;
if (ballx[i] > (width) || ballx[i] < 0) {
ballxspeed[i] = -ballxspeed[i];
}
if (bally[i] > (height) || bally[i] < 0) {
ballyspeed[i] = -ballyspeed[i];
}
}
}
