    text
    copied!<p>I've uppgraded to PhysX 3.2 and have been struggling for days to have my test box moved by gravity but it simply won't to it.</p> <p>I've followed the PhysX documentation but implemented it in my way. It's pretty much a default setup:</p> <pre><code> physx::PxSceneDesc sceneDesc = physx::PxSceneDesc((physx::PxTolerancesScale())); sceneDesc.gravity = physx::PxVec3(0.0f, -9.8f, 0.0f); if(!sceneDesc.cpuDispatcher) { physx::PxDefaultCpuDispatcher* mCpuDispatcher = physx::PxDefaultCpuDispatcherCreate(4); if(!mCpuDispatcher) LOG("PxDefaultCpuDispatcherCreate failed!"); sceneDesc.cpuDispatcher = mCpuDispatcher; } if(!sceneDesc.filterShader) sceneDesc.filterShader = &amp;physx::PxDefaultSimulationFilterShader; physxScene = physMgr-&gt;getSDK()-&gt;createScene(sceneDesc); </code></pre> <p>Creating the dynamic actor:</p> <pre><code> PxRigidDynamic* body = mPxSDK-&gt;createRigidDynamic(Convert::toPxTransform(transform)); PxRigidBodyExt::updateMassAndInertia(*body, 1.0f); mPxScene-&gt;addActor(*body); </code></pre> <p>Add the box shape:</p> <pre><code> PxBoxGeometry geometry = PxBoxGeometry(Convert::toPxVector3(size)); if(geometry.isValid()) { PxMaterial* material = api-&gt;createMaterial(0.5f, 0.5f, 0.1f); PxShape* shape = createShape(actor, geometry, material); PxRigidBodyExt::updateMassAndInertia(*body, 33.0f); } </code></pre> <p>Simulating the scene as:</p> <pre><code> float elapsedTime = float((float)mTime.getElapsedTime() / 1000.0f); mAccumulator += elapsedTime; if(mAccumulator &lt; mStepSize) { return; } else { mAccumulator -= mStepSize; mPxScene-&gt;simulate(mStepSize); mDynamicBodySys-&gt;updateGameObjectPositions(); mPxScene-&gt;fetchResults(true); mTime.restart(); } </code></pre> <p>When I look into the Visual Debugger I can see the box and the frame count increasing. But it's not moving. The actor's and the box shape seem to have the correct propeties. LinearVelocity is increasing in negative Y axis, its mass is 33 etc. But the pose is still zero/identity. What am I missing?</p>
