QuoteBegin-spengo+2 February 2006, 22:30 --> | QUOTE (spengo @ 2 February 2006, 22:30) | | So, kinda like the sonic game for the 68k calcs where the level is made up of a few different sections that it has to load for half a second when you hit the edge so you can continue? (really annoying on some loops) |
Yes & no...
While you are in a world map... you never have to stop to load a section of it. The entire 64Kb map is in RAM. The original Ultima V had to load a new section of map everytime you walked 16 steps. Now, that was a pain in the butt. I did not want that in this version.
To enter a town, you need to stand directly on top of it and choose the "Enter" menu item. Then, it loads the town map. Town maps are 32x32 tiles. They are a zoomed in view of the world. Even time moves slower while you are in a town. So, in a sense, it makes good sense to "stop" for a second while everything readjusts. This is a non-real-time RPG, not an action game which needs to have smooth action.
Currently, to exit a town map you just walk off the edge of the town map. In the original, it asked "Exit to Britannia?". I don't know if I will put that in. What do you think?

QuoteBegin-spengo+31 January 2006, 19:17 --> | QUOTE (spengo @ 31 January 2006, 19:17) | | No, it decompresses before you play right? It's just so it stores smaller and takes less flash mem. |
You are pretty close... It works like this:
I have a 64Kb buffer in RAM. I use this buffer to decompress all maps and NPC data. So, everytime I enter a map (except combat maps), I have to load and decompress the new map data.
For example: if I am in the world map "Britannia" and enter the town "Trinsic", then I have to load and decompress the town map into the RAM buffer. This effectively replaces the world map -- since they utilize the same RAM buffer. So, when I exit the town, I have to reload and re-decompress the world map. It only takes about one second to decompress that map data; but it is a BIG savings on flash memory.
I have 2 world map files -- each 64Kb decompressed
I have 1 dungeon map file -- about 45Kb decompressed. It contains 8 dungeons; each dungeon has 8 levels. And, 112 special combat maps.
I have 4 town map files -- ranging from 40Kb to 60Kb decompressed. Each town map contains 16 maps that are each 32x32 tiles; and all of the NPC locations, schedules, and talking scripts associated with these maps.
They all use the same RAM buffer for decompression.
I also have 16 standard combat maps and shrine maps, but they are not compressed and reside in flash memory. They can be accessed directly at anytime -- in towns, in the world map, in a dungeon... etc.
Whew... That was alot of typing! THE POST

Women... Can't live with 'em... Can't live without 'em   Hang in there Fred! This is simply not fair. I went through a similar situation when I was in high school. I think this is a fairly common part of getting older. It is normal to spend some time grieving. This grieving will build you up and strengthen your character. You will become a better person because of this -- isn't that ironic? You have a lot of friends that care about you -- focus on them. It sounds like this girl is missing out on a fine young man -- you! :thumb:

QuoteBegin-spengo+31 January 2006, 1:26 --> | QUOTE (spengo @ 31 January 2006, 1:26) | | Second- the ttpack thing, is it better than the pre-os packing thing? |
I'm not sure... that is a good question to ask... I just don't know the answer (does anyone else know?). :  :  TTPack works really well for Ultima. My overworld and underworld maps are both 256x256 tiles maps (64Kb each)... and TTPack compresses them down to 12.5Kb. Nearly a 75% compression ratio... that is pretty darn good!

QuoteBegin-Liazon+29 January 2006, 19:50 --> | QUOTE (Liazon @ 29 January 2006, 19:50) | | How is that done? I mean how do you compress data? |
You can get TIGCC Tools Suite. In it there is a program called TTPack.exe. Use this program to compress your data files. And, in the Extgraph library, there is a function called ttunpack_decompress() that will decompress files at runtime... Cool. B)  edit: Once you compress your data file, you need to convert it to TI file format using TTBin2Oth.exe or it is also called tovar.exe. QuoteBegin --> | QUOTE | | and is it possible to have a separate program for data storage? |
Yes. In fact, this is the preferred method for larger games. Ultima V uses external files extensively.

QuoteBegin-xlibman+29 January 2006, 18:29 --> | QUOTE (xlibman @ 29 January 2006, 18:29) | | cool, how big is it so far? |
Game engine = 51Kb
Game data = 160Kb (compressed)
The game engine is what I need to be careful of, it cannot be greater than 64Kb.
BTW: Using Skull keys works now (10 items out of 40 can be used). Skull keys are used to unlock doors that are magically locked.

Ultima V Update: I have been working on the 'Use' command lately. There are about 40 items to use in Ultima V. I have implemented 9 out of 40 so far. B) Also, I have been working on some memory optimizations. I was able to save an additional 3Kb of RAM. B) THE POST

Congrats Saubue! Third place is nothing to be ashamed of. Hey... At least 8 people voted for Astrosmash. Not too bad for a 25 year old video game. How is Lemmings coming along? I can hardly wait :woot:

QuoteBegin-Liazon+26 January 2006, 16:07--> | QUOTE (Liazon @ 26 January 2006, 16:07) | | Can the _R ones be used interchangeably? or can I only input values of the "register short type?" hehe, must be the register part that is confusing me. |
Yes, they can be used interchangeably.
Don't worry too much about the 'register' keyword. It is basically a compiler implementation modifier that says "if a register is available, then use it". If a register is not available, then the compiler will choose what to do. Putting values directly into registers is just a bit faster. In your Extgraph API call above, it expressly states to put parameters you pass into registers D0, D1, and D2.
