3rd tutorial on ASM- and HW-coding
So, I'm back with yet another very popular Amiga-effect:
Rolling an image around a copperbar. This is just a 32px tall copperbar and a 100px tall image. Just to spice up the screen a little bit I put 5 of the same rolling copperbars, and to get a little extra from them I have all five images on the copperbars with a small offset. Next up will be 64px/200px, and probably with 2 different executables as I did some testing on what kind of routine would look the best. Surprisingly the more mathematically correct method didn't render the better endresult (looking at the test, it isn't really that surprising). |

It would be nice of you if you could put your website in your signature or something.
Redsector and SF used that effect IIRC Kamelito |

Good idea, especially as I forgot to include the address to the website in the previous post
Let's see if this works. ==> And no, no signature. So, here is the address to the website: http://vikke.net |

The downloadable source has Windows CR/LF line endings. A lot of Amiga assemblers don't like that.
Some more hints to improve compatibility with assemblers: - Always start labels at the first column. PhxAss, vasm will fail otherwise. - Do not use the BLK directive. Devpac will fail. Use DCB or DS instead. Keep up the good work! |
