Title: Joltima in C Remake
Post by: Athlor on July 13, 2006, 01:23:00 am

I've put aside Ultima DR temorarily to work on a remake of Joltima in C. It's been 8 years since Justin Karneges created and released Joltima and I'd like to make a sequel, Joltima II and a sci-fi rpg off this same engine. Yeah, I know about the Joltima II version then changed into 'Infinity' rpg for the Gameboy color Justin did. I wish that source was released! The sequel will be an all new story, more refined maps and graphics and a little extra code.
I'm about 80% through it and should finish within a month. It is a remake as opposed to a port because the code is all new from scratch. It even uses the same RLE16 compressed versions of the maps. The sequel will work with the original TI-83 assembly code.
So all together there will be TI-83, TI-89, Blackberry 957 & 857 and Cybiko versions.

Those screenies are awesome... O_O

For a game like that, I doubt that you will be able to get it to fit in the 27K RAM that the 83 only has, unless you meant the 83 plus series of calcs.

No, the screenies are from the Blackberry 957 version. But when I finish it, the data for the sequel and the sci-fi rpg can be compiled with the original Joltima asm source and be used on a regular TI-83. I've chop out 400 bytes in the original source so far.  o.o

@Liazon - it is also on the 83, so it is both z80 AND 68k!

I meant 68k, I said this because since we alerady have joltima for z80 i dunno if there would be much point to port it to those model again :P but it would be cool with all the new gs spritez XD

You may have noticed the dungeon pics have no line-of-sight code. That will be the hardest part, I think. The source even had a pregenerated array in c. I haven't a clue yet how to implement it as yet.
I'm also not sure I have the exact sequence of combat down right. I'm going to use animget to study it better. I added the wiggling when struck code part in last night. ;)
It's technically playable but not really right yet.

I use a pregenerated array in C to accomplish the LOS algorithm. It is so much faster than actually trying to calculate it. I had to have an intermediate tile grid of 17x17 tiles, because Ultima V has light sources, which really complicated the LOS algorithm. Would you like some help implementing it?

I also need to add the "wiggling" algorithm for the Tremor spell among other things.

What exactly is "animget"?

Keep up the great work Athlor!

I wish joltima source was released, it would make the task even more easier if you understand the basic concepts of z80
