How to Use the Solus Katana Mech Arm On Planets

[Kaiser]

The Solus Katana Mech Arm won't work properly in gravity, at least by default. I've found a way to trigger it reliably though.

While on the ground, click to engage the blade.
Then, without pushing left, right, or down (up still works), jump. The Solus Katana will make you lunge toward your cursor as normal at the peak of your jump. You can release early, just doing a quick hop, to lunge quickly.

If you have pushed A or D at any point during your jump, the katana will not trigger. You can be moving while you engage it, but you must stop and jump to make the attack. Still definitely needs fixed. Preferably, it would at least work if you press the button at any point while airborne. I've no idea how to look into coding this or I would do it myself.

Even more silly:
If you equip two solus mech arms, triggering both will cause the second one to make you charge toward your cursor without jumping, and even dashing across the ground as ... what I can only assume, is intended.
