So I was bored and started working on this, one year later I was bored again and finished it.
This is my attempt on creating 3D maneuver gear in Minecraft,
This mod doesn't seem like much, but I've put quite some effort in it, it has a fully functional dual wielding system (without any coremodding), bauble rendering system and some flawed vector math.
If you're interested on how it's done, or you think you know how to improve it, the code is fully Open Source and can be found on GitHub by clicking on 'source' on the banner above.
How to Use:
This mod requires Baubles by Azanor, to get started, first craft a set of Maneuver Gear and a Maneuver Gear handle. The maneuver gear is equipped in the belt slot and the handle is used to operate it, you'll notice that it is dual wielded. From Minecraft 1.9.4 and onwards, you need to equip one handle in each hand.
left clicking operates the left handle, right clicking the right, not difficult to understand. Regular click swings the respective weapon, but it doesn't do any damage! That's right, you first have to equip a blade into the handle. Blades can be equipped on the handle by equipping them from your holster. You can visually see how many blades you have left in each holster and there is a tooltip as well.
To equip a blade from the holster ctrl + click (left for left handle/holster, right click for the right).
How do I get blades in my holster you ask? Craft a couple, and right click with a blade in your hand to put them in the right holster and shift-right click to put them in the left holster. Yes you can hit enemies with a bare blade, but you'll probably cut yourself.
Okay, now that you've got down how to equip blades and attack, let's talk about actually using the maneuver gear. Shift + click launches a grapple (again, left click the left and right click the right), a subsequent shift + click instantly retracts the corresponding grapple.
It is possible to start reeling in a grapple (and pulling yourself towards the hooked grapple) by holding the hotkey (default: 'z' for left and 'x' for right).
And that's basicly how to use the maneuver gear. Oh right I forgot, while wearing the maneuver gear, while holding shift and pressing space, instead of jumping you will vent gas out the nozzle on your back effectively trusting you in the direction you are facing.
P.S. You will take fall damage, a lot, that's why there is special impact compensating boots to reduce fall damage. Or you could use something else to prevent fall damage of course...
