Re: Scraping an A3020

Hi Joe,


I have an A3010, and am looking to replace the bottom half of the white plastic case as one of the four plastic protrusions that the keyboard sits on has broken off. As you are breaking the A3020 for spares, would you be interested in selling the bottom half of the case to me?


Andrew.

Re: Sprite Masking

The Rocketman sprite in the first Planet Nubium game was drawn using the XOR method. Here the background undergoes a bitwise XOR with the sprite. The method is quite simple and the same bitwise XOR routine is used to remove the sprite. However, with this method when Rocketman crosses over a coloured...

Re: Sprite Masking

Planet Nubium Two uses a sprite mask to display the Rocketman sprite. First, the background where the sprite is to be plotted is copied to a scratch area of memory. The screen memory then undergoes a bitwise AND with the sprite mask, then undergoes a bitwise OR with the sprite itself. The result is ...

Re: About BBC Basic 4

To draw the sprite in PN1 a CALL is made from the BASIC part o...

Holy Cow Ed, I thought the game would take you longer than that to complete!

The 68 was there to test game completed routine. I will fix the 'feature' for the Version 1.0 release, or you can change 'ob%=68' in line 390 to 'ob%=0'.
