Update 4This updates been a few days in coming, I'm currently out of the country so doing Kodama things isn't as easy as it was before.
Anyway, today I did a quick test of an ougane 大鐘 (Great Bell) and a Shumoku (special Clapper for this kind of bell, essentially its a log on ropes) together.
Its far from perfect, the physics will take a while to get right, especially for the rope, and the movement code for Kodama pulling the log needs sorting out too. but essentially speaking, Kodama is able to pull the shumoku(clapper) back and ram it into the bell, this will actually serve a gameplay purpose of course.
Quick gif to show the shumoku layer being turned on and how the phyics are instantly applied, not perfect as I said but good. I'll be making the vines on the log use vine physics too, so they move about when the object does, instead of sitting stiff as a statue
Bare in mind that this scene, unlike all the others so far, isn't actually from the game itself, its just a small test, thats why the scale is all skewed.And an additional gif of Kodama bowing to say thankyou to all the interested forum members.
Would be nice to know how did you achieve the rope things.
