hello,
but you are a programmer now!
The error I spotted is rarely known even by the best so don't worry about this. It was not a obvious error.
new version
improved:
- once the random number for the array is set, it's not changed anymore (till we hit next sphere) - more stable text - achieved by: see isNearMouse
- only one sphere can have text, not two at the same time - no overwriting text - achieved by: method displayText does return a value and the for-loop breaks (exits) when the first text is dsplayed
- all spheres are drawn first, then all text - no sphere can be painted above text (so it looks better) - achieved by: two separate for-loops in draw, separate methods display and displayText
