Hi,

I've been playin AxySnake (www.axysoft.com) recently and I have found it to be an awesome game. Highly addictive.

I am into making my own snake game, but instead of eating fruits the snake will be chasing/eating mice and avoiding assorted obstacles. I wanted to make a realistic snake movement because I want it to be a really good quality game.

I am wondering, what should I do to get the realistic snake movement (like in AxySnake). I am assuming that you would need to create a straight snake model and then create a fine bone structure and then export it (along with textures and all) to an .X file.

Now, would it be possible to do something like this:

When the head (main bone) moves, all the other bones follow recursively (bone 2 follows bone 1 and bone 3 follows bone 2 and so on in that order) I am thinking this would give you some sort of realistic snake movement (that's what I am thinking anyway)...of course, someone mentioned limbs (are limbs the same as bones in DBPro?).

I am just wondering if this is indeed possible in DBPro. I am sure this would be possible with memblocks and manipulating meshes, but that would be a hideously difficult task indeed (if at all possible) and probably a lot less efficient not to mention slower.

Does anyone else have any ideas...

I know DBPro supposedly supports bones (allowing us to work with individuals bones and to work with things such as spinal structures as in the case of a snake), so I'm hoping that I'll be able to do the sequential recursive bone moving technique rather than messing around with mesh manipulation.

Any ideas or suggestions would be greatly appreciated.

Cheers,
Ben

if you have a look in the 20 line challenge forum, there are some snake entries there, but what you want to do sounds more complicated so i really have no idea

Yup. This can be done in DBpro. What you need to do is to create a skinned mesh in your favourite 3-D modelling package. When I say skinned mesh, meaning that you need to model your snake's bone and its skin separately.

I usually use MAX to model my game. So for your case, I will create a bone structure of the snake. The bone structure will most probably have several segments. Some segments might move according to other segments, i.e. something like our wrist bone moves according to our arm bone.

Once you had the bone structure done, you need to model the skin mesh. You will tie each vertices of the mesh appropriately to the bone vertices. By this way, when you animate the bone, the skin will stretch automatically following the bone. Neat eh? Just like the real skin and bone.

For animation, you can choose to animate it in your 3-D modelling package. Or you could animate manually by using the DBpro limbs command. If you need a fine control over the animation, I would said the latter choice is a better choice, but more tedious. You need to think of how to rotate each bone naturally by using some math. Maybe you can use some simple sine/cosine trigonometry. Afterall, snake movements do look like a sine wave. LOL!

Hoped this helps!
Good luck!

good advice/good suggestions!!

makes me wanna go make a snake (-:

I've had an idea bout snake movement.
I'll go and test it out.
If it works, then I'll post the code.

OK it may be jittery a buggy but it shows the principle:

That movement is rather elastic though. You should move the objects as soon as the leader is moved, rather than on a time basis.
