Re: 2d and other graphics modes

Other options for flat 2d are 1st-person (usually a view from a racing car, a crosshair for FPS shooters) Behind view (racing genre is the only that comes to my mind) Your description sounds like 3D perspective... Do you have any examples? Perpendicular 2.5D Graphics looks for me same as `Diagonal-...

Re: Devfinitive Edition (Mike Richardson): vote

I expected more votes for Thanatos! Become a dragon. Rescue a sorceress about to be sacrificed, carrying her on your back. Breath fire on a village, or grab an archer with your claws then drop him from high above to hit others. How cool is that? By comparison, Turbo Esprit is a great game, but it's ...

Re: Oblique 3D Graphics - true or not?

Let us see user's case to seek for games. I know a cool game, e.g. renegade or double dragon and i am impressed with its graphics mode, that oblique 3d. I want to see other games that are like renegade and i click link "oblique 3d". But i see that `3d painter` and `pippo`. No. That's like...

Re: Oblique 3D Graphics - true or not?

https://i.postimg.cc/mgGC4gRK/Clipboard-03-09-2024-02.jpg This (top-down?) oblique projection was used in many games with RPG Maker, here Vampires Dawn. As you see the characters are drawn from a side view but that still fits nicely. I agree it looks nice. However that's not oblique or 3D. In ZXDB ...

Sure, almost every 3D game for the Spectrum have 2D characters. When done properly (like in Renegade) it looks great.

This looks like perspective projection. https://spectrumcomputing.co.uk/SCRtoImage.php?SCR=/conv_scr/p/Pandemia.scr&border=0 All objects are oblique. Except each side of the screen has a different angle. The last level of Renegade uses the same idea. However it doesn't look wrong because the si...

Re: A request for new tags

One option is, we can start classifying games into 2 separate tags "Multiple Boss Fights" and "Final Big Boss Fight", with possibly a few games on both. Depending on how many titles we find for each group (and how many "gray areas"), we may decide later to merge both gr...

The final boss in Renegade is clearly everyone else's boss. He carries a pistol and can shoot at the player, all others are unarmed.

Re: Simple path finding algorithm in assembler

Ah, I've looked up the DB for Dijkstra and A-Star before trying myself, but the search didn't turn up results. I like the idea of storing the path lengths directy in the maze. I am using 8-way movement (instead of the 4-way in your algorithm) but this could be worked out by adding either 2 or 3 to ...

In case of PATHFINDER, support for weighted terrain would require using one priority queue (implemented as binary heap) instead of a simple queue.

Re: Simple path finding algorithm in assembler

And if you want fast instead you can't go much wrong with A*. A* "optimality" makes it faster for large mazes. However Spectrum games don't have large enough maps to compensate it. For smaller mazes, it's probably faster to just solve the entire maze instead of spending time with heuristi...

Re: A request for new tags

Another gray area is: should we give Renegade a "end-level boss" tag too? It depends if we consider the last boss in Renegade as yet another end-level boss, or an end-game boss in a separate category from the others.

A single tag for bosses would be much easier...

There's something similar called PATHFINDER : The PATHFINDER library is a small efficient Assembly implementation of the "simplified Dijkstra" algorithm for finding shortest paths in small mazes, that you can freely use in your own programs. It uses 512 bytes as temporary queue and only 89...

Re: A request for new tags

But well, we already have tags for filmation and filmation-2 engines that group 2/3 titles only. Features are a very different situation from series and sets. It doesn't make sense to say "there are not many games created with Filmation II engine so let's combine them with something else"

Re: A request for new tags

I think the tag itself is a great idea. However we still need to sort out the details. For instance, Castlevania has many bosses but it's a continuous game. Therefore they are neither end-level bosses or end-game bosses. Also if there are too few games in this list, we should probably have a single ...
