As you may have noted from the readings there are a few different ways of managing objects. You can use simple object literals or create objects from classes. You can start with object literals and as your sketch builds up in complexity you may find it clearer to use classes, especially if you have more than one distinct behaviors to manage.
sketch - A Snake Following the Mouse
Array of object literal with properties x and y.
sketch - drag trail of n bubbles
Array of objects using modern Javascript class Bubble.
sketch - Ex_11_09 Managing Many Objects
JitterBug example using old function style objects from "Getting Started..." book.
sketch - Ex_11_09 Managing Many Objects-remix
JitterBug example re-mixed to use modern Javascript class.
Compare these examples. Run them and examine the array of objects in interactive console. Note the difference between object literals and class objects.
sketch - Ex 6.2 JitterBug re-mix
The JitterBug example re-mixed to use a button to add JitterBugs to canvas.
- add logic to keep the bugs on the canvas
sketch - Ex 6.2 JitterBug clamped
- modify to drag to create bugs
sketch - Ex 6.2 JitterBug drag
- limit the number of bugs created
sketch - Ex 6.2 JitterBug limit
- reduce the randomness and draw lines between the bugs
sketch - Ex 6.2 JitterBug line
- modify to draw individual figures
- add button to save figure as JSON
- animated drawn figures
- replicate figures at different sizes and positions
Sketches from the Getting Started book You are invited to remix and combine them to further explore.
