http://www.nexusmods.com/starbound/mods/102/?tab=1&navtag=http://www.nexusmods.com/starbound/ajax/moddescription/?id=102&preview=&pUp=1 this is the hang glider mod found on the Nexus by feryaz. I love the notion of this. I would love to see some graphical work done on this, in order to have the player correctly lying prone and using the glider. It'd be great too, to see a version per race. If needed I can reference the old Sonic games where I think it was a feature
I don't believe changing the pose is possible. As far as I know, the player renderer is completely hard-coded, adding poses and such is impossible without access to the base code. The best that could be done is to flip the character sideways, like the sleep animation.
I was hoping, if someone was willing to rework the mod and the author was willing to give them the code, it could be altered to have a file for each race. if making the character use it properly is not feasible than at least reworked for each race would be nice.
