[BEHAVIOR] Chipmunk Physics

The ball staying transparent is odd, probably an issue with the physics library itself or maybe a typo on my part. You can fix it by adding a system compare: Ball.Chip.CollisionOtherObj != Ball.UID, so I guess the object is colliding with itself?

Yea, I tested it a bit more and found that all of the objects' other collisions get replaced by itself:

Filtering out with CollisionOtherObj != Ball.uid is a good idea for the ball itself but my real problem is how it loses collision with the ground

Ok, I see what the issue was. Re-download on first post. The other object will never be the same object now.

In your example if two balls are stacked only one will get an opacity of 50, so you need an action to set the ball's opacity as well.

The reason why only one gets opacity reduced is because one of the balls still has itself in CollisionOtherObject.

I changed the cap so both balls get lifted away from the ground and made the text display the first number is Ball.UID then the next numbers are CollisionOtherObject

So here, 12 and 13 are colliding, but they both have 13 as their CollisionOtherObject

Thanks for the capx. Fixed now. Re-download in first post.

Awesome! it all seems to be workin great now.. thanks man, you are legendary

Hello,

Thanks to you for the work done with your plugins. It's really helpful as I had troubles using Box2d and asm.js, with crash and can't fix it or neither understand. Some people have same problems of various threads in the forums, so your plugin is the only alternative.

Many thanks !

What is the difference between box2d linear damping and chipmunk one ?

—

The box2d one is per object, whereas the chipmunk one applies to everything. You can replicate per object with a force proportionate to the object's speed and in the opposite direction.

I have a box with physics behavior falling from top to down when i touch the box i set the max speed to 40 which allow me to decrease the speed of fall and everything is okey the issue is when i want to change the direction of that box ( after the click) with swipe left or right i have tried the force but it doesn't work, the box is still fixed on the same target.

Perhaps use a larger force?

It's okey Thanks =)

Hi!

i'm trying to solve a problem. When a box hits the ground in movement, the box doens't react to the speed of the groung and stays in the same place. What i'm doing wrong here?

Is the ground moving with the physics behavior? All other movement behaviors are unmoving to the physics behavior. Otherwise I don't know.

No, the ground is with bullet behavior. thats probably the issue. i'm going to change it. Thans a lot!

I still have a problem though.

I got the ground moving, but to keep it running I need to change the gravity to zero. But everything around is affected.

How do I change gravity individually per object?

My project is based on two oposite gravities, up and down, and diferent objects must fall in oposite directions.

With box2d I can't do this, and I though I could do this with the chipmunk, but I don't know how.

thanks in advance for your help
