以前版本的PhysicsSimulation的shapeCast方法在3.2里面已经没有shapeCast了，而且文档上面还有。
1想问下后续会不会补上这个方法,以及什么版本会有。
2我们把原来的方法copy过来，发现执行跟2.0的物理执行结果不一致，想问下是哪有问题。代码如下[code] let bt = Laya.btPhysicsCreateUtil["_bt"];
        PoolPhysics._btTempVector30 =  bt.btVector3_create(0, 0, 0);
        PoolPhysics._btTempVector31=  bt.btVector3_create(0, 0, 0);
        PoolPhysics._btTempQuaternion0=  bt.btQuaternion_create(0, 0, 0, 1);
        PoolPhysics._btTempQuaternion1=  bt.btQuaternion_create(0, 0, 0, 1);
        PoolPhysics._btTempTransform0=  bt.btTransform_create();
        PoolPhysics._btTempTransform1=  bt.btTransform_create();

        physics._simulation.shapeCast=function(shape, fromPosition, toPosition, out = null, fromRotation = null, toRotation = null, collisonGroup = Laya.Physics3DUtils.COLLISIONFILTERGROUP_ALLFILTER, collisionMask = Laya.Physics3DUtils.COLLISIONFILTERGROUP_ALLFILTER, allowedCcdPenetration = 0.0) {

            var bt = this._bt;
	        var convexResultCall = this._btClosestConvexResultCallback;
	        var convexPosFrom = PoolPhysics._btTempVector30;
	        var convexPosTo = PoolPhysics._btTempVector31;
	        var convexRotFrom = PoolPhysics._btTempQuaternion0;
	        var convexRotTo = PoolPhysics._btTempQuaternion1;
	        var convexTransform = PoolPhysics._btTempTransform0;
	        var convexTransTo = PoolPhysics._btTempTransform1;
	        var sweepShape = shape._shape._btShape;
	        bt.btVector3_setValue(convexPosFrom, -fromPosition.x, fromPosition.y, fromPosition.z);
	        bt.btVector3_setValue(convexPosTo, -toPosition.x, toPosition.y, toPosition.z);
	        bt.ConvexResultCallback_set_m_collisionFilterGroup(convexResultCall, collisonGroup);
	        bt.ConvexResultCallback_set_m_collisionFilterMask(convexResultCall, collisionMask);
	        bt.btTransform_setOrigin(convexTransform, convexPosFrom);

	        if (fromRotation) {
	            bt.btQuaternion_setValue(convexRotFrom, -fromRotation.x, fromRotation.y, fromRotation.z, -fromRotation.w);
	            bt.btTransform_setRotation(convexTransform, convexRotFrom);
	        }
	        else {
	            bt.btTransform_setRotation(convexTransform, this._btDefaultQuaternion);
	        }
	        if (toRotation) {
	            bt.btQuaternion_setValue(convexRotTo, -toRotation.x, toRotation.y, toRotation.z, -toRotation.w);
	            bt.btTransform_setRotation(convexTransTo, convexRotTo);
	        }
	        else {
	            bt.btTransform_setRotation(convexTransTo, this._btDefaultQuaternion);
	        }
	        bt.ClosestConvexResultCallback_set_m_hitCollisionObject(convexResultCall, null);
	        bt.ConvexResultCallback_set_m_closestHitFraction(convexResultCall, 1);
	        bt.btCollisionWorld_convexSweepTest(this._btCollisionWorld, sweepShape, convexTransform, convexTransTo, convexResultCall, allowedCcdPenetration);
	        if (bt.ConvexResultCallback_hasHit(convexResultCall)) {
	            if (out) {
                    let _physicObjectsMap = Laya.btCollider["_physicObjectsMap"]
	                out.succeeded = true;
	                out.collider = _physicObjectsMap[bt.btCollisionObject_getUserIndex(bt.ClosestConvexResultCallback_get_m_hitCollisionObject(convexResultCall))];
	                out.hitFraction = bt.ConvexResultCallback_get_m_closestHitFraction(convexResultCall);
	                var btPoint = bt.ClosestConvexResultCallback_get_m_hitPointWorld(convexResultCall);
	                var btNormal = bt.ClosestConvexResultCallback_get_m_hitNormalWorld(convexResultCall);
