Prepare yourself for a grand adventure! Ultima™ IV, sixteen times larger than Ultima™ III, is a milestone in computer gaming. Lord British has produced a game to challenge not only your physical and mental skills, but the true fabric of your character. The evil triad of Mondain, Minax, and the hellspawn Exodus have been vanquished and peace reigns throughout the land of Britannia. Evil yet abounds, but in isolated pockets and in the hearts of men. A new age awaits the coming of one who can conquer evil on all frontiers through mastery of both magic and the use of force. Daemons, dragons, and long-dead wizards still plague the countryside and must be destroyed. The seeker on the path of the Avatar will face hostile groups composed of mixed enemy types and will survive such encounters only by strategic use of weapons and terrain. Earthly victories over seemingly impossible odds lead to the final conflict, where the ultimate challenge - the self - awaits.
Take a look at this screenshot:
How many differences can you spot between it and vanilla Ultima IV for dos?
10 points if you can spot 10!
OKay, some are old, or have been shown in previous screenshots. Howver, several are new, and represent some work done recently.
Tweaking/Improving the raycasting was no small chore. And it is not done yet. I think it represents one of the major differences between the dos port and the original Apple II version. I didn't really realize how big a change it was until I started tweaking it. There was always something about the Apple raycasting, that lent to the danger of the adventure. Perhaps it was that the screen was always a little darker, perhaps it was that you couldn't see what lurked around the corner. Whatever it was, I liked it, and getting it going in Trinity is on.
Here are some gifs comparing the two versions of the algorithm I have come up with, with the original dos and Apple II versions. Neither is a perfect replica of the Apple 2 algorithm, but they are much closer than dos. The funny thing was, I barely modified the dos algorithm. Only the tiniest tweak, almost like fixing a typo, was enough to make the algorithms effects align very closely with the Apple IIs. Odd.
Ray Cast Version One
Ray Cast Version Two
Ray Cast Apple II Version
Ray Cast Original Dos Version
I definitely like both my new algorithms, but which is better...Hmmm...Kinda leaning toward version 2...
