From 8ffe905c455eaa33394dafe67858df12d767fc27 Mon Sep 17 00:00:00 2001 From: Marcel Admiraal Date: Mon, 9 Dec 2019 11:11:06 +0100 Subject: Check for motion in cast_motion() before doing Bullet convexSweepTest(). Also ensure that default closest_safe and closest_unsafe values are defined in cast_motion() and before cast_motion() is called. --- modules/bullet/space_bullet.cpp | 18 ++++++++++++------ 1 file changed, 12 insertions(+), 6 deletions(-) (limited to 'modules/bullet/space_bullet.cpp') diff --git a/modules/bullet/space_bullet.cpp b/modules/bullet/space_bullet.cpp index 99f58e7059..1b6ccbcef4 100644 --- a/modules/bullet/space_bullet.cpp +++ b/modules/bullet/space_bullet.cpp @@ -152,6 +152,15 @@ int BulletPhysicsDirectSpaceState::intersect_shape(const RID &p_shape, const Tra } bool BulletPhysicsDirectSpaceState::cast_motion(const RID &p_shape, const Transform &p_xform, const Vector3 &p_motion, float p_margin, float &r_closest_safe, float &r_closest_unsafe, const Set &p_exclude, uint32_t p_collision_mask, bool p_collide_with_bodies, bool p_collide_with_areas, ShapeRestInfo *r_info) { + r_closest_safe = 0.0f; + r_closest_unsafe = 0.0f; + btVector3 bt_motion; + G_TO_B(p_motion, bt_motion); + + if (bt_motion.fuzzyZero()) { + return false; + } + ShapeBullet *shape = space->get_physics_server()->get_shape_owner()->getornull(p_shape); btCollisionShape *btShape = shape->create_bt_shape(p_xform.basis.get_scale(), p_margin); @@ -162,9 +171,6 @@ bool BulletPhysicsDirectSpaceState::cast_motion(const RID &p_shape, const Transf } btConvexShape *bt_convex_shape = static_cast(btShape); - btVector3 bt_motion; - G_TO_B(p_motion, bt_motion); - btTransform bt_xform_from; G_TO_B(p_xform, bt_xform_from); UNSCALE_BT_BASIS(bt_xform_from); @@ -178,9 +184,6 @@ bool BulletPhysicsDirectSpaceState::cast_motion(const RID &p_shape, const Transf space->dynamicsWorld->convexSweepTest(bt_convex_shape, bt_xform_from, bt_xform_to, btResult, space->dynamicsWorld->getDispatchInfo().m_allowedCcdPenetration); - r_closest_unsafe = 1.0; - r_closest_safe = 1.0; - if (btResult.hasHit()) { const btScalar l = bt_motion.length(); r_closest_unsafe = btResult.m_closestHitFraction; @@ -196,6 +199,9 @@ bool BulletPhysicsDirectSpaceState::cast_motion(const RID &p_shape, const Transf r_info->collider_id = collision_object->get_instance_id(); r_info->shape = btResult.m_shapeId; } + } else { + r_closest_safe = 1.0f; + r_closest_unsafe = 1.0f; } bulletdelete(bt_convex_shape); -- cgit v1.2.3
