rigidbody go through the wall after applyCentralImpulse

2013-07-11T04:25:57+00:00

i am implementing an air hockey game using AwayPhysics

when the puck collide with the stick, i add central impulse to the puck

sometimes the puck will go through static rigid walls i set in the scene

and this often occurs when the puck moves fast

i am a newbie to AwayPhysics and i think the reason for this is that

the position simulated has already out of walls

but i don’t know how to adjust that

could anyone help me, thanks!!

Both side and anta-alias issue with Flash Player 14 in Chrome

2014-07-29T10:22:06+00:00

Hi everyone !

Today, i updated a Away3D project developped a few month ago.
I was surprised with the bad render of the 3ds objects in the scene. The both side no longer work and rendering is not quality.
Look at the attached file to understand the issue.

At first my Flash project run with Away3D 4.1.5. I have updated to 4.1.6 but the problem persists.

The problem come with the new version of Flash Player in Chrome v14.0 !

//Setup Scene
_scene = new Scene3D();

_view.camera = _camera;
_view.mousePicker = PickingType.RAYCAST_BEST_HIT;
_view.backgroundColor = 0x131313;

w.apply(mesh);
   
var explode:Explode = new Explode();
explode.apply(mesh.geometry);

var material:TextureMaterial = new TextureMaterial(Cast.bitmapTexture(pAmfPiece.textureDiffuseCustomBitmap));

FLASH CS5.5how to use awayphysics.swc

2011-11-16T03:07:05+00:00

I set awayphysics.swc as libirary swc file ,when i debug it swf ,error said AWPRigidBody isn`t defined ,AWPPhysicsWorld isn`t denfined ...!when I locate awayphysice original file into root path ,error said module.AwayPhysica is unimprove initClid is un`t defined…!

what should i do?

Error #1506: The specified range is invalid.

2014-11-04T01:45:28+00:00

When do quickly create AWPRigidBody and addRigidBody to world, had below issue.

Am making a game to catch coocckies which is falling from the sky. Am able add awayPhysics .Now the cookies falling from the sky and created a box which catch the coockies. But the problem is the coockies inside the box go throuh the box walls when i move fast the Box. I adjusted the mass value . But still is not working .. this is my code :

AWPBvhTriangleMeshShape surface is not smooth

2013-11-22T20:46:39+00:00

Hi there,

I am creating a ball game, where a ball follows a way. The way is a AWPBvhTriangleMeshShape. But unfortunately, the ball jumps up and changes its direction when it is rolling over edges - even if the surface is flat.

I have created a project to reproduce this behaviour. There is a PlaneGeometry and a SphereGeometry. When moving the ball, it starts to jump at the edges of the plane surface.

I have uploaded a movie of the project, where you can see the ball jumps up: http://de.tinypic.com/r/2ibymh5/5

Is this a bug or is there a solution to get rid of this problem? I really need the AWPBvhTriangleMeshShape, as the way is not a straight one.

Here is the code, woul’d be very happy is someone coul’d help me out.

obj - AWPBvhTriangleMeshShape terrain problem

2013-02-01T19:55:49+00:00

Hi guys,

Someone can see and eventually correct this…
Here the source:
http://www.estiva2.altervista.org/Away3D/CarSampleMod1.7z

( the source contains two version of library incuded in the 7z file )

This is important for me… With version 4.1 i can load the right material or/and texture but the physics can’t work…

Thanks in advance

AWPBvhTriangleMeshShape error

2013-07-14T02:55:06+00:00

Hi guys,

Please help me with this problem:

var mat:ColorMaterial = new ColorMaterial(0x4B871F);
mat.lightPicker = stateLight;
var mesh:Mesh = Mesh(ObjectContainer3D(e.target).getChildAt(0));
//mesh.scale(100);
mesh.material = mat;
//view.scene.addChild(mesh);
var shape:AWPBvhTriangleMeshShape = new AWPBvhTriangleMeshShape(mesh.geometry);
var body:AWPRigidBody = new AWPRigidBody(shape, mesh, 0);
body.scale = new Vector3D(40, 40, 40);
world.addRigidBody(body);

I’m using away4.1.1 and awayphysics-core-fp11-master

Thanks!

6DofConstraint motor problem

2013-06-04T00:11:01+00:00

We are working on a project and were getting a random 1125 error in bullet. We decided to update to 4.1.1 beta and the dev branch of away physics. The update seem to fix the crash we were getting but we are now having a problem with one of our constraints with a translational motor not working.
We have 2 of them set up one that slides back and forth along the Z axis it still works ok. The other slides along the Y axis up and down however it longer wants to move. I’ve tried increasing the velocity and motor force to no effect. Any one how any ideas? Heres the code that sets up the rigidbody and constraint.
This was all working on the 4.0.11 alpha build with the master branch of awayphysics.

var rigidbodyPiece : Object = new Object();
