#GETWORLD GREENFOOT CODE#

This book provides you with the knowledge and processes necessary to create engaging interactive applications in Greenfoot. Greenfoot is designed to ease the transition into this immerging field, allowing for the easy development of two-dimensional graphical applications, such as simulations and interactive games. I'm trying to make it that the world will spawn spikes within itself at random coordinates every 6 seconds.The worlds of computers and art are merging in new and complex ways. It is not the same 'counter' field that is declared near the top of the class.As I said, i'm very new to coding. Again the 'counter' variable is declared within the 'for' statement and its scope is limited to the 'for' loop. I did notice the somewhat strange use of the 'for' loop using a 'counter' variable.

That is ambiguous, as it could be interpreted as being in context with time or with space (locations throughout the map). Your initial statement used the phrase 'at set intervals' when referring to the random spawning of spikes throughout your map. Still, assigning it after calling 'addSpikes', when the method needs it assigned first, is kind of pointless. If that be the case, you could just remove the 'int' at the beginning of the line thereby, not declaring a local field, but using the static field declared above. Maybe you intended that this line assign a value to your static field with the same name. It creates and assigns a variable that is local to the constructor (its scope is bound to the constructor itself) then, it is ignored that is, it is not ever referred to or utilized later within the constructor. Line 14 is what I call a 'hanger' line - it has no purpose. In fact, it is never assigned a different value EVER. The static field, 'randomNumber' has an initial value of '0' and it is never assigned a different value before the 'addSpikes' method is called in the world constructor. Line 19 compares the value of 'randomNumber' with '0' and will find it never to be greater than '0'.
