From e5bfa98d0fa6a1acb1d385534c51b8006ef64142 Mon Sep 17 00:00:00 2001 From: Tristan Porteries Date: Tue, 10 Jul 2018 12:50:14 +0000 Subject: Expose bullet shape margin to UI. The margin value is exposed into the UI for shape ressource. This value can be modified through set_margin and get from get_margin or by using the property margin. Each time the margin is modified the associated collision shape is recreated and the margin value is used in ShapeBullet::prepare. --- modules/bullet/bullet_physics_server.cpp | 12 +++++++++ modules/bullet/bullet_physics_server.h | 3 +++ modules/bullet/shape_bullet.cpp | 45 ++++++++++++++++++-------------- modules/bullet/shape_bullet.h | 24 ++++++++++------- 4 files changed, 55 insertions(+), 29 deletions(-) (limited to 'modules') diff --git a/modules/bullet/bullet_physics_server.cpp b/modules/bullet/bullet_physics_server.cpp index 6246a295ec..e767988593 100644 --- a/modules/bullet/bullet_physics_server.cpp +++ b/modules/bullet/bullet_physics_server.cpp @@ -159,6 +159,18 @@ Variant BulletPhysicsServer::shape_get_data(RID p_shape) const { return shape->get_data();
