this is what my project should look like but i have no clue how to use if and else and booleans correctly. need help
http://www2.sunysuffolk.edu/struckc/CST112/applets/Project4/

and this is my codes




//// The x- and y-coordinates
int x=159;
int y=0;

//The direction and speed
int speed = 1;
int moveX =1;
int moveY=1;
//colors
int myWhite= 255;
//declare a variable boolean
boolean toggleSwitch = false;

void setup()
{
  size(300,400);
  smooth();
}
