Potion FX not implemented #14

Closed kieranhj closed 6 years ago

kieranhj commented 6 years ago

Not sure what potion FX are missing but obvious one is screen flipped upside down. On Apple II this is implemented by just reversing the order of entries in the screen scanline look up table. Unfortunately this isn't going to work on a Beeb because of the character based screen layout. Might need some cunning approach involving self-mod code to hack the plot functions. :S To be figured out. :)

Also missing fx for when the weightless timer is ending (screen or player flash?)

Done in branch!

Upside down FX PR'd to master. Just thinking about a quick palette effect for weightless - although on couldn't see the FX on Apple II (swaps between hires & double-hires with same screen buffer) and couldn't see an FX on PC playthrough.

Done. Simple flash black backgound to green when weightless running out.
