In my setting, I'm trying to develop interesting movement/combat mechanics. I asked a related question about ways of slowing free-fall descents in an effort to develop exoskeleton-enhanced parkour. There were numerous problems with that, and even the methods that made sense meant losing the "spirit" of the movement dynamics I was looking for. Among the many interesting and thought ideas posted -- and still being posted -- there, one that stuck with me was that of "super pogo-sticks."
This got me thinking about some other crazy stuff leaning more towards science-fantasy than straight science fiction. That said, I do want to understand some of the possible physics involved here to make my idea work. Yes, there's serious amounts of handwavium being applied here. That aid, I do want to focus on the mechanics involved of creating a pushing device like the one below.
Below I have the idea, followed by some supporting images, and then the problem I'm facing. It's some scrolling.
The Idea Handheld "Booster-Blades" (I haven't come up with a better name yet) capable of creating a handwavium empowered "energy field" that can that serve three functions:
Creating a wide, rounded shield that blocks particles and waves. So no bullets, no lasers. It's just a really tough shield.
The shield's seconndary function is that it can be "pushed" with great force, allowing the wielder to spring off of hard surfaces.
The Booster-Blade also allows a sharp, pointed "Power-Lance" or perhaps "Power-Hook" designed to stab bad guys, by getting around their shield. Or perhaps also "hook" onto things.
In this setting, the shields have negated much of the utility provided by ranged ballistic and directed energy weapons. Thus, people have opted towards becoming the projectiles themselves. Just bear with me. I'm not trying to figure out how much sense that makes (just yet). Thus, using shield-pushing and the lance, people basically use "sword and shield" fights but as human pinballs, where much of the skill comes from your talent for creating interesting and unexpected angles.
I like the video-game esque movement and combat mechanics at play, but I'm worried about how they decelerate their falls. I'll handwave HOW the shield is tangible, but not how basic physics works. If you catch my drift.
When I first came up with it, I thought the grips on the booster-blades might be pressure sensitive, allowing them to "slowly extend" the shield as they gripped harder or bring it back as they loosened up -- allowing them to cushion their falls to a stop or sort of "pogo" back up.
In my head, it would be like clap pushups -- you don't land rigid, or you snap your shoulder; you slowly decelerate before popping back up.
If the shield's extension and contraction is controlled by how hard you grip the handle, or perhaps by turning an exoskeleton-attached throttle like that of a motorcycle, would it be possible to use such a pushing-device to cushion your falls?
I like the idea of shield-pushing. I know there's lots of handwavium being applied to the shield itself, but, if you grant me that, how could it be used to decelerate and permit the sort of vector-based combat I'm looking for? Does the throttle/grip solution make sense?
If the force behind the shield was like that of a "spring" it might make sense, right? If it could contract, storing up potential energy for subsequent release, would that interfere with other functions like being able to "bash" with the shield or use to stop projectiles?
What are my options?
Thank you all.
