Hi,
I have the following question:
I want to draw a bouncing ball.
First thing I do is create a class:
EllipseMorph subclass: #Ball
instanceVariableNames: 'position'
classVariableNames: ''
category: 'PBE-BouncingBall'
Then an initialization method that mostly do a super initialize.
Then the drawOn:
drawOn: aCanvas
aCanvas borderWidth:10; borderColor: Color green.
And finally a position method:
position: aPoint
super position: aPoint.
position
^ position.
Finally in a Playground I do:
| aBall |
aBall := Ball new.
aBall position: ( 10@10 ).
aBall openInWorld.
But I get a red box with two crossing yellow lines.
What I'm missing?
Thanks in advance.
