"Portal" in Applesoft BASIC!
|
|
|
|
Note: Portal is most likely a registered trademark of Valve
|
|
This program is in no way endorsed by them.
|
|
|
|
After finishing Portal (late to the game as always) I felt inspired
|
|
to do the closing credits/still_alive song on an Apple II, as I found
|
|
most other architectures already have a version.
|
|
|
|
And once I've done that, it's a short step to implementing the rest of
|
|
the game.
|
|
|
|
It's not really complete (it was really meant as a demo for the video)
|
|
but it's surprisingly playable.
|
|
|
|
I'm about at the limit of what you can do in an 8kB Applesoft program.
|
|
The frame rate is much worse than the early versions too.
|
|
|
|
My biggest issue was with trying to get all 6 colors displaying properly,
|
|
especially when using shape tables. I guess one can curse and praise
|
|
the Woz simultaneously.
