Katamari Challange

Recommended Posts

Check this link if ya don't know "Katamari Damacy" game:

http://en.wikipedia.org/wiki/Katamari_Damacy

In this challenge you must create the main effect from the game which is a ball which glues everything to itself

Rules are simple:

-glue works when it hits the object

-objects can glue to other glued objects

-such construction has certain resistence and can be broken when push is heavy

Enjoy :D

Hey kumpa

I can't give you any hints because this is a challenge and I don't wanna spoil all fun for the others. If you really don't know how to reach this effect then wait until there will be some hips.

If you wanna do this task you must know for sure stuff like: data flow in DOPs.

peace

Oi,

this challenge is flame-buoyant! It brings in so many aspects of DOPs usage that having it done is a kind of mini-exam in DOPs already. I am doing fine and can already make the objects stick to the ball, however I've got to make other objects stick to the whole group now. So, here are my questions:

1) is there a cheap way to check whether an object is glued to some object?

2)is there a way to predict whether an object will be torn away? Maybe check the accumulated impulse with the collision impulse strength?

Thanks.

Wow! I'm impressed!! :D

There will be a next stage of this challange for you. I've got an idea,

but unfortunately no time at the moment,

I'm really busy this week.

As soon as I find some time, I'll show it to you.

MADjestic and MIguel!! Good work!! Very good work!:)

Congratulations!! :thumbsup:

After about 8 hours (!!) i finally figured this one out, including how to get the sphere to accumulate other objects on top of ones it has already stuck to.

the solution i came up uses a script solver to deal with the impact data and decide which object to glue something to. simply put, i'm storing the objects impact "otherobjid" field, so long as it isn't the ground plane (easy since that is ID 0 in my net), and then i'm setting the glue object field in an rbd state object with:

`dopobjectlist($DOPNET, dopoption($DOPNET, $OBJID, "AuxImpacts", "firstImpactID"), 1)`

where AuxImpacts and firstImpactID are my custom names.

i tried using chops for this, but couldn't figure out how to preserve the data from the dynamics chop, as the impact data exists only for one frame. i suspect this might be possible, but i just don't know how to wrangle data in chops well enough yet. is there another way to do this? anyway, i learned a lot doing this challenge... thanks!
