You make 1 widget. You show 3 instances of that widget, each with different data.
How do I choose 3 random from the 20 total?
- keep abilities in an array
- shuffle, grab the first three
- make widgets, show the abilities
- remove the chosen one from the pool once it has been selected
Pseudoscript:
Games that implement this: vampire survivors, rogue tower, brotato.
Disclaimer: going by the description, no clue how those games work, only heard about the 1st one. Brotato sounds catchy, though!
