A 4th year assignment I had where I had to make a 2D application
The title I was given Digital life and Evolution
Notes from my report:
- Environment's design considerations
In this project, I
had to consider the new design issues of working in 2D and keeping
track of the items that would be drawn to the screen, also, where on
the screen they should be placed and in relation to other items.
- Methodology
The methodology
for this work was primary one of experimentation. Over the weeks of
this project it slowly evolved into its current stage.
- Implementation
To implement this
project, I first drew up a layout plan for how it should look and how
the user would interact with the programme i.e. where hills would be
drawn, how the courser would move, types of random patterns …etc.
When creating the
growing plants, I used random number to influence the size and
direction of them but I also needed to found where the next part of
the plant should grow from. I got this by finding the midpoint of a
line on the side it would grow from.
The stars that can
be dropped in the sky are created by placing a dot where the courser
is and randomly setting the brightness and speed of this rotation
around the top centre of the screen. The change in brightness helps
to create a feeling of depth.
The
implementation for this work contained some key features:
I used separate
files for each of the classes in other to make code navigation
easier.
I created
management class to better control the multiple instances of the
class.
Array-list was
added to allow for dynamic growth of the group of objects.
The key words
“Height” and “Width” were used throughout the code to allow
the graphics to adapt to changes in the setup size.
I added a screen
help view (that can be selected by pressing the “h” button on the
keyboard) to make navigate the environment more easily.
I also replaced
the courser with a small floating rectangle which glows in a cycle
and change size based on the speed of the mouse movement. This adds
to help it amerce the user into the environment.
- Screen shots
A view of the programme, when it first starts.
When the help screen is displayed.
The view after several star and plants, have been dropped.
