| Post subject: | Mode 2 Masked Sprite plotter |
New Wiki page with a Mode 2 Masked Sprite Plotter; http://www.retrosoftware.co.uk/wiki/ind ... te_Plotter It's very extensively commented and comes with a down loadable Swift project and also I've tried to make this fairly Swift independent so people should be able to load it into other P65 set-ups fairly easily. But for complete ease it'll run straight from Swift. As always feel free to improve it. Even with all the comments in the code it may not be obvious to newcomers to the Beeb screen layout what exactly is going on, so as soon as I get time I will put some additional text and diagrams explaining the method in more plain English. |

Wiki updated to show screen shot of demo and also the source file now includes switching to Mode 2 and redefining logic colour 8 to actual colour 0 (black) as logical colour 0 is used as the Mask. |
