Many roguelikes have a choice of "class" for replay value. Could we have that in HyperRogue, with its focus on non-Euclidean geometry, and combat based on just positioning (no hitpoints etc.)?
Apparently yes! Here the Rogue switches his blade for a crossbow, and takes advantage of how the straight lines work in hyperbolic geometry in a different way!
As a consequence of hyperbolic geometry, the enemies naturally arrange themselves in a straight line, which this crossbow attack takes advantage of. This is work in progress that should be available soon (the classic HyperRogue combat is attack adjacent creature, which also takes advantage of this property, but in a different way). Of course there is more variety in HyperRogue from the choice of geometry, land structure, and change of genre from roguelike to action/FPS/racing/etc.
Still needs some improvements, but already available for some early access testing in HyperRogue 12.1x. HyperRogue 12.2 should be released soon!
Here the arrows reflect in mirrors, and also we have some mimics, who shoot mimic arrows. Last seconds show that the arrows indeed fly in straight lines, even after reflecting off mirrors. #screenshotsaturday#HyperRogue#HyperbolicGeometry
You cannot tile a hollow sphere with hexagons. But you can pretend.
Some games and animations pretend they can tile a sphere from the outside [ https://twitter.com/ZenoRogue/status/1439246553877729286 ] but I have not seen this done with the inside. This is the WIP HyperRogue feature of embedding 2D geometries into 3D geometries; in this case, the Euclidean world map is embedded as a (hollow) horosphere in 3D hyperbolic space. Expect more weird visualizations based on this (:
If they expand in the same 'z' direction, but with different rates instead, it looks more like a horosphere (compare the first visualization in this thread); this is why hexes in the visualization below are squished when we look at them orthogonally from far away. #mathart#noneuclidean#hyperrogue#rogueviz#mathviz#visualization
You are a lone outsider in a strange, non-Euclidean world. As a Rogue, your goal is to collect as many treasures as possible. However, collecting treasures
attracts dangerous monsters (on the other hand, killing the monsters allows more treasures to be generated).
You can kill most monsters by moving into them. Similarly, if the monster was next to you at the end of your turn, it would kill you. The game protects you from getting yourself killed accidentally by ignoring moves which lead to instant death (similar to the check rule from Chess).
