I added charging rockets and tried to tweak it so that it felt right.
And if you don't like videos, here's the trajectory prediction at min charge :
(the rocket will actually hit something before reaching the end of the line, but adding collision detection to each dot eats cpu time)
And at max charge :
Perhaps a couple of fixed classes with kinda different weaponry, or a perhaps the item can select a few items/weapons from a wide range of them. Or maybe select gadgets for weapons, or something similar.
I'm still very much tweaking things in the gameplay department, so I'm open to ideas. Classes I'm not too excited about, mainly because the game also has straight deathmatch, and balance would be a nightmare.
I'm considering adding pickups in the map for special powers, like a super hook (faster, goes further), more powerful jetpack, antigrav boots, things like that. They would be temporary of course, but give an edge to a player who can grab it and use it properly.
