Thanks, they are perfect (both of your examples). Just a last thing about yours, R0j0hound. I noticed that your solution results sometimes by a Javascript error "the body is undefined". It's not a real problem because it doesn't concern the place I need to put this lampe, but I still can't figure out why it happens. Any idea ?

Okay this was clever, I wasn't. Indeed, it works ! But the thing still swinging now, like if someone just gave it a little push. Is there a way to make it immobile at the beginning ? Thanks for your answer anyway, it really helped me, as easy as it was x)

Nobody use Chipmunk physic here ? :/

Guys ? Someone ? Okay I was maybe too specific, in brief, how can I make a realistic string by using joints and physic objects ?

I can join the capx of my previous attempt if you need it (the one with the crazy shit on the ground, be careful I bet this thing want to eat your head or something). I just want to build a physical lamp hanging from the ceiling which reacts well realisticly with another physical object (like my sprite or a rock or I don't know, your favorite duck for instance). You know, this kind of stuff :

The way I see it, it's a movable object (the lamp itself) related to an immovable object (the ceiling) thanks to a pivot joint (the cable). Am I wrong ? If I'm not, why are all my attempts "alive" and "hyperactive" as soon as I define the corresponding joint ? Thanks in advance

Hello everyone,

I'm here because of my snake which is a lamp. I mean, it supposed to be a lamp, so 3 rectangles and 1 triangle with some pivot joints for hold them together. But I certainly missed a step, and now the thing is on the ground with horrific spasms, like a demonic snake which tries to reach a yoghurt river or whatever.

To be precise, here's a small drawing and the action related to it. As you may understand, a rectangle is a link, so several rectangles connected will be a string. But look at these two rectangles with two image point, I make the joint by connecting their image points...isn't that how we're supposed to do it ? What's wrong exactly ?

Hum that's very interesting, can I ask how did you do your own behavior ? Is it in HTML5 or just by using the Custom Behavior option ? Where and How can I do that exactly ? Can't be so hard I guess, I just need Box2D with the controls of the platform behavior.

(Plus I looked Umbra, seems to be a great work dude !)

Noted, sorry

Hello everyone. Before you start, yes, I know that Platform Behavior and Physic Behaviour don't match together, no worries.

It's exactly why I'm actually here. I have some questions about it, and I'll be glad if you take some time for me

So ! I'm currently working on a platform game. My animations are ready, so are my layouts. Here we go :

1) So I absolutely need of Physic in my game, so I have to add this behaviour to everything (ground, sprites and blablabla). Okay. But now, I suppose that I have to define every single move and control of the character by myself in the events sheet, right ? (It's not a problem if there is no alternative, I'm just curious. But If I had to do it, I'll do).

2) Physic is love, Physic is life. But Physic is expensive too. And I don't really know how much. As I said, I'll add physic to every objects in my main layout, but I have to draw the polygon collision points myself too (cause C2 knows what a square is, but certainly don't know how to deal with my different platforms). The fact is : I'll probably end up with 14 or 15 sprites composed of 20 or more polygon collision points. It's recommanded to never exceed 4 or 8 so...well. Huehuehue I guess. How much is that important ? Will my game really by slow and heavy because of that ?

3) It's not REALLY connected to my previous questions but, I'm curious about the object "light Shadow". Well. I've seen some creations with it and I was like "Oh my golden fish, this is gorgeous" but I didn't try it yet and I don't know if it's compatible with everything-is-freaking-physic-in-this-layout-dude-deal-with-it. Is it ? (I'll read the doc about it as soon as possible, I just ask)

Thanks in advance if you can answer me mates.
