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]; } } }
