I've been trying to make a scrolling engine but I'm not having much luck :S



.SCROLL
ClrDraw
[003C7E7E7E7E3C00]->Pic1
[FF818181818181FF]->Pic2
Pt-On(40,40,Pic2
Repeat getKey(15)
Pt-On(X,Y,Pic1
If getKey(1)
Y+1->Y
Vertical -
End
If getKey(2)
X-1->X
Horizontal +
End
If getKey(3)
X+1->X
Horizontal -
End
If getKey(4)
Y-1->Y
Vertical +
End
DispGraph
End
That is my code and what is happening, attached is the source code.

My problem is that the scrolling is not working like, for example, in a RPG, and I want it for each time the ball moves 1 pxl, that little square moves one pxl too in a controlled way, isntead of what is happening (everything is crazy)

Hello, I was told here at Omnimaga that afterall we can use more than Pic0-Pic9. What are those 'more'?

If those 'more' exist, I may go back to calculator programming (this is what made me give up).

Hey, I know that some of you have made games with pausing systems that work with a key to pause the game.

How does that work? How do you do it?

I wanted to implement it in uPong and was wondering how.

Thanks much!

Hey there, here is a GIF and the code of how to move a smilie, just change the code to whatever you want to get a moving mouse, a moving dog, or whatever you want.

.SMILIE
.The Sprite, change the Hex to whatever you want
[004466000000817E]->Pic1
.Do everything below until CLEAR is pressed
Repeat getKey(15)
StorePic
.Display Sprite
Pt-On(X,Y,Pic1
DispGraph
Pt-Change(X,Y,Pic1
RecallPic
ClrDraw
.Right Key
If getKey(3) and (X<92)
X+1->X
End
.Left Key
If getKey(2) and (X>2)
X-1->X
End
.Down Key
If getKey(1) and (Y<60)
Y+1->Y
End
.Up Key
If getKey(4) and (Y>2)
Y-1->Y
End
. End of the game loop
End


For any of you who have been wondering what the Prizm is all about, I gathered some information here.

The Casio Prizm is the latest Casio calculator and is one of the firsts, if not the first, full colour calculator. For us, programmers, these are good news since we can know code programs and games that are not MONO or Greyscale. This is Casio's actual information about the Prizm:

PRIZM™ is revolutionary among graphing calculators with features that enhance users’ understanding of mathematics. With conventional graphing calculators, students learn by inputting equations to create graphs. PRIZM™ creates a whole new way to learn math by enabling students to experiment by creating their own graphs over pictures of real-life scenes, and then understand the functions from the graphs that they created on their own.

A while ago I said the PRIZM would be great for programmers. However, students and teachers can also benefit a lot from the implementation of colours in calculators. Why? In many, many ways such as graphing several functions and giving each one a specific colour to help us analyse it, or as Casio said, create graphs with backgrounds such as landscapes and buildings, to help us understand better the use of functions in real life.



A coloured calculator is also much easier to handle than greyscale calculators. It's much easier for human eyes to understand things if they are coloured. In fact, surveys have proofed that highlighted text is more easily memorized by our brain.


On the other hand, the PRIZM is not all about colours, there are many other impressive features implemented in this calculator.

New color enhancements, images, Picture Plot technology - PRIZM must burn through batteries, right? Wrong! Despite all this powerful functionality, PRIZM uses less energy because of the ground-breaking display technology. It will perform perfectly for 140 hours before dry-cell batteries need to be replaced. You can also use rechargeable batteries, which will last for 85 hours.

Casio says that the PRIZM can be turned on for about 140 hours with dry-cell batteries! This is fantastic for a coloured calculator, which supposedly would have a much smaller battery life.

How many times have you wished that your calculator had more memory?

The Casio fx-CG10/PRIZM has 16MB of flash memory, 10MB operational. For additional specification and how PRIZM relates to other Casio graphing calculators and competitive models, see the related comparison chart.

The Prizm has quite a lot of memory, compared with the TI-83+ series, but for a calculator with colours, which means pictures and maybe videos, I feel that it could have more memory.



And so I finish my comments on the new Prizm with a picture of its keyboard, which I think, could be more functional. Some may also agree with me that this calculator could use some more beauty. However, the cons of the Prizm are easily outweighed by the pros.

To help me with my disassembler which has lots of instructions working already, but a few not working, I decided to create this post in order to get help, otherwise I'd go  .

These are my Assembly and Hexadecimal Assembly questions.

QUESTION 1:According to the table here, [22] is:

ld (**),hl
In Assembly I'dd just:

ld (12),hl
But how should I do that in Hexadecimal?

QUESTION 2

ld hl,(**)
The same doubt as above but for [2A].

QUESTION 3

Since I'm coding a Disassembler, how should I handle bytes like [CB], [DD], [ED],[EF]? These link to other tables.



Thanks much for the help!

Hello everyone,

Some of us like to use HEX to program in Assembly, not many, mostly Xeda and calc84maniac. I also like it, but don't do it much.

Eitherway, at:

www.davidgom.co.cc/z80table.html

You can find an online, HTML browser z80 table with the HEX code for everything.

Note: I didn't make the table, Collin Anderson did and uploaded it to ticalc.org, here.
I only converted it to HTML, uploaded it and host it.

I have e-mailed him asking him whether he is okay with me uploading it or not. If he says he doesn't want it there, I will remove it, but for now it is there.

It was hard work (making it HTML) by hand, so I hope you like it.
