Modifying loops

Onke’s modified loop – source code

How do you think Onke managed to start the loop further to the right? He did it by changing parameters of the function, like this:

  //use for loop to draw series of pacmans across the screen
for(x3=0;x3<width;x3+=radius){
  pacman(x3+100, y3+30,luhlaza, false, radius, 1);  
  }

Can you think of another way that he could have done it?

Mfuneko’s pacman disappears – can you see why in the source code?
