Animating a bow and arrow.

Post by stuyk »

Hey, I'm having trouble creating the bones for the string on the bow so that the character can pull back on it (I don't know any of the technical terms, sorry!). The bow is part of the same image as the left hand, and the arrow is in a switch layer attached to the right hand. The whole character, including the bow and arrow, uses the same skeleton. Thanks in advance!

Shouldn't be too complicated. Bind the bow to the holding hand bone. The bowstring needs to have at least 3 points. Use the region binding tool to select only the middle point and bind it to the pulling hand bone.

The arrow should have two versions, the one before shot and the one after shot (flying). The flying one must be separated of the man's skeleton to disconnect form his movements. A simple change of visibility in the right moment would be enough to switch between one arrow and the other.

I'm really unfamiliar with the vector tools. I've only ever really used the 'import -> image' and then creating a skeleton, etc... is there a simple way to do this if the string is an image, too?

That's not possible with an image.

Here's an example with vectors, but I used only regional binding so this same thing should be doable with images. (I just didn't want to hunt up or make an image for this.)

Creating bones for a bow and arrow is total overkill and unnecessary in my opinion. You could just use point motion. A line with 3 points. 2 anchors and one in the middle where it goes back. There's 2 positions - at rest, and loaded. That's all really.

I've ended up doing a lot of it on my graphics tablet and then importing the frames as an image sequence. I tried with vectors but since I'm so unfamiliar with the tools I just made an absolute mess of it and I need to have this done quite soon.

thanks so much for all the feedback!
