                                  Introduction 
                                  ????????? 
Once again you are sitting in front of the monitor tense on what the new lesson to be 
present this time ... We have had time to Lesson 6 now, and it 
begin soon resemble something now. You have taught you copper, how to show pictures, 
and to some extent to show sprites. So far we have not so much as 
Nosate at the notorious blittern, but I promise that there will be a long time 
to. This time, I have to go through some additional things that belong 
to the sprites. Hope you can tolerate this and are waiting with bated breath for the next lesson. 


                                    Theory 
                                    ????? 
I mentioned something about Attached fashion in the last lesson, and I will go into a little 
closer to it now, I thought. 
   As I said, an alcohol can only have 4 colors max. This is a bit 
pathetic, and it is precisely because Attached fashion has been created. In attached mode 
combine two spirits into a single, and may, instead of only 2 
bitplan, whole 4 pieces, which offers 16 colors. 
   Spirit shares can only be combined in spritepar as follows: sprite0 with 
sprite1, sprite2 with sprite3, sprite4 with sprite5 and sprite6 with sprite7, 
which means that you can not put together tex sprite0 with sprite6. 
   Putting an alcohol in the attached mode is pretty simple. It is just 
bit # 7 in control WORDet in both spirit and ensures that they always 
at the same coordinates. 
   The appearance of them is then fully with autopatrol magic DMAn. 


                                  Register 
                                  ???????? 
As usual spirit of fashion is of course the colors a bit strange, so that Sprite 0 
and 1 has color 16-19, Sprite 2 and 3 color 20-23, etc., but fashion is attached 
is a little different. Where parts ALL sprites on the colors 16-31, we have 
several sprites at the same time we must ensure that they have the same palette, 
otherwise it will be pretty ugly. 


                               Program example 
                               ??????????????? 
This time, I have done a little flexible programs displaying four 
pieces attached in the spirit of fashion (they're made in only 8 colors was to 
I could have both blue and yellow) that bounces around as obsessed on 
screen. 
   I run X and Y change in two different routines. The Sine Swing do I 
no bounce at the Y-coordinate, by reading from a sinus table and bring 
in the value of the liquor control WORD. The routine Spirits Move, move, I 
booze either left or right, and see if it reached the right or 
the left wall yet, and it does so only do I change direction. 
   I must admit that spirits makers look disgusting ugly, but I recognize that 
I drew them myself, and I'm no graphics ... :-) 


                                  Challenge 
                                  ???????? 
The challenge was apparently FOR easy or what is this?? Not a single reply! 
It really is not fun ... A little feedback on my work would be 
fun! But, but ... It is well-summer heat that makes you not able to sit 
inside and Button Bar on the computer .... 
   I have a solution in all cases, which I think is the smallest neatest 
way to do it. Throw gladly flukt on it. 


                                   Questions 
                                   ?????? 
Now I have some questions! It is getting nasty acid that does not make 
any more than to write a piece of code and a little text to a deaf-mute 
masses who never speaks! Do you have left school or not? Can I 
get some debate, or tricky questions someday? 
   Well, questions submitted in all cases easily in 22 Acacia Avenue:

                                  ????????? 
Now do I get a little break with grade school because I want to go to 
sunny Italy for a month so the next lesson will be completed and 
available at the base on July 24. 
   I hope you will bear with this, you take a proper rest from 
encoding and go out for a while in the sun! Cynez!
