| + | ==Some Explanations== | ||
| + | |||
| + | * There are 2 new elements in the program: | ||
| + | ** <tt>float diameter</tt>, and | ||
| + | ** <tt>random( )</tt>. | ||
| + | * <tt>float diameter</tt> simply says that '''diameter''' is used in the program as a ''variable'' that will contain a real number (real numbers are numbers with a decimal point). | ||
| + | * <tt>random()</tt> is a function that returns a random number. If you call <tt>random(10)</tt>, it will return a random number between 0 and 10, not inclusive. So, when we write: | ||
| + | |||
| + | diameter = random( 200 ); | ||
| + | |||
| + | :we make the sketch store a random number into the variable diameter, and we force this random number to be larger than or equal to 0, and less than 200. | ||
| + | :When we call '''ellipse()''' and write <tt>random(500)</tt> for both the ''x'' and ''y'' coordinates, we make the sketch put a circle in the window at a random position, but we force the center of the circle to remain inside the window. | ||
| + | |||
| + | ==Your Assignment== | ||
| + | |||
| + | # make your sketch display circles only on the sketch only when the mouse button is ''pressed''. | ||
