Hex with Sprites
«

Hello All,
Could someone please explain how hex works with creating sprites and all that? All I really know is that
[FFFFFFFFFFFFFFFF]
creates a solid 8*8 block while
[0000000000000000]
leaves a blank 8*8 area. Any help is very appreciated

Well, do you know how hex is just a representation of binary? 0=0000,1=0001, and so on, with C=1100, E=1110, and all the other hex digits.
You basically just draw your 8*8 sprite, and then for each row make two hex digits, one for each four bits in the row. For example, 11001001 is C9. Do this and you will have 8 pairs of digits, for 16 total. Reading these left to right, top to bottom gives the hex code for the sprite.
For the reverse, put the 16 digits into 8 rows, two digits in each row. Replace each digit with the binary that corresponds to it, and you'll have an 8*8 sprite.
Maybe I forgot to mention this, but black pixels are 1's and white pixels 0's.
Hope this helps!

A 8x8 binary sprite is made of 8 binary strings of 8 numbers.
1
=black and
0
=white. If for example, the first row of your sprite is
1
1
0
1
1
0
1
1
, separate it like this:
1
1
0
1
1
0
1
1
First, using the chart above, would be D, while the second would be B, in hex. Combined together gives DB. If you got a 8x8 sprite, repeat the process with all 8 rows of pixels.
Alternatively there are some pic to hex or bin to hex converters in the Axe parser forum and on ticalc.org, which speeds up the process in some cases, but I think the method above is the fastest to convert them manually.

let's not forget
http://www.ticalc.org/archives/files/fileinfo/389/38904.html
It was made specifically for this function, converting a sprite into hex code. ^ ^

Thanks guys
I'm not really looking for a "Sprite-to-Hex" converter (besides to look for examples of how) because I just needed to kinda understand the basics so I can hopefully implement it into a program I plan to work on soon.

CalcGS is also highly recommended. It supports sprites & tilemaps plus 4-level grayscale and will export data that you can use with your assembler.

Doesn't calcgs import sprite data in a rather strange way, though?

I use this one. Its really basic, but its great for monochrome images and supports any size you want.

that one gave me an hard time, though
When I tried to run it I ended up with full of missing .OCX/.DLL errors and had to go search them online to get it to work
To anyone wanting to use this program, watch out for viruses if you download OCX files because some sites aren't very legit

Isn't that the one in the downloads section? Or is that a different one?

It's in the downloads sections. I still need to add a few alternatives, though.

With CalcGS you can import from the clipboard or from BMP's. The only thing you have to remember is to set the size.

can it import tiles from a BMP tilesheet? I mean, will it separate them in 8x8 tiles if you tell it to do so?
