[BEHAVIOR] Chipmunk Physics

Oh thanks for looking into it. I kinda just forked it from things I found from google searching. I have ~0 knowledge of JavaScript (if any) and to be honest C2 is the only thing I am familiar with.

I indeed was switching between polygon and paster. I just left both in as an option. Polygon has a 'draw line' option which helped distinguish the cubes. Paster is in much lower resolution and as the performance was already slow I didn't attempt to see how it would look if I increased Paster's resolution.

What I attempted to do was to only calculate the 3D view of one cube at the center, and then to just apply it to the rest of the cubes, maybe helping in performance. But I couldn't figure it out. As it is now it calculates the view for every cube.

I think it would be great if everything could just be done in javascript for performance but that is way beyond my knowledge.

I will define the function onStartOfLayout and see how it goes. Thanks

I got carried away with some ideas and I posted an example here:

construct.net/en/forum/construct-2/your-construct-2-creations-23/more-rojo-tests-138761

Came out pretty clean. The idea is you generate the cube image any way you want, then only once per frame load an animation frame.

Are there any way to draw the joints like in the Joints and Constraints video example?

You’d have to do it manually. Ideally there are expressions to get the position and such I’d the joints. Or if not you could save the values when you add the joints.

Then you’d just position sprites or use a drawing plugin to place lines and stuff

I'll try those out... Thanks a lot!

The behavior lets you utilize joints and collision filtering. Those would be used as the building blocks to make the more complex examples you listed. I have no pointers at the moment but it's just the kind of thing you'd just figure out to do as you go.

How make No Collision

of Group (Familly) ?

Like in Box 2d

For make ragdoll doll.

Hi, one question please, is this behavior more advanced than the official one included in C2? Does this behavior allow us to do more things ?.

Or can the same things be done with the two behaviors and are they just different?

nelostic

There are two things:

collision groups. When two instances are in the same group they won't collide. It's just a number.

Collision layers. It's a series of 1's and 0's, one for each 32 layers. Two objects will only collide if they share a one in the same position.

the Mnk

It adds collision filtering, and a lot more joints as well as other improvements, as well as various differences.

have construct 3 vrrsion ?

Nope.

This is an awesome plug in. Thanks.
