From 225027ce5dea3785626908b58b01fb3959cf8362 Mon Sep 17 00:00:00 2001 From: Pierluigi Grassi Date: Sun, 15 Mar 2015 17:26:11 +0100 Subject: BGE - new read-only attribute in KX_GameObject python api (LOD level) Added a new "current_lod_level" property to the python api of KX_GameObject. The property returns the current lod level of the game object. The purpose of the property is activate logic routines only when an object is at a certain lod-distance from the camera, avoiding to separately recomputing the same distance in the logic script. Usage in python script might look like: owner = bge.logic.getCurrentController().owner lod_level = owner.currentLodLevel if lod_level == 0: ...do something else: ... object might be too distant Reviewers: dfelinto, kupoman, moguri Reviewed By: kupoman, moguri Subscribers: lordloki Projects: #game_engine Differential Revision: https://developer.blender.org/D978 --- source/gameengine/Ketsji/KX_GameObject.cpp | 4 +++- source/gameengine/Ketsji/KX_GameObject.h | 1 + 2 files changed, 4 insertions(+), 1 deletion(-) (limited to 'source') diff --git a/source/gameengine/Ketsji/KX_GameObject.cpp b/source/gameengine/Ketsji/KX_GameObject.cpp index 8d22c9132fd..71af263bf46 100644 --- a/source/gameengine/Ketsji/KX_GameObject.cpp +++ b/source/gameengine/Ketsji/KX_GameObject.cpp @@ -91,6 +91,7 @@ KX_GameObject::KX_GameObject( : SCA_IObject(), m_bDyna(false), m_layer(0), + m_currentLodLevel(0), m_pBlenderObject(NULL), m_pBlenderGroupObject(NULL), m_bSuspendDynamics(false), @@ -794,7 +795,7 @@ void KX_GameObject::UpdateLod(MT_Vector3 &cam_pos) } RAS_MeshObject *mesh = this->m_lodmeshes[level]; - + this->m_currentLodLevel = level; if (mesh != this->m_meshes[0]) { this->GetScene()->ReplaceMesh(this, mesh, true, false); } @@ -1927,6 +1928,7 @@ PyMethodDef KX_GameObject::Methods[] = { }; PyAttributeDef KX_GameObject::Attributes[] = { + KX_PYATTRIBUTE_INT_RO("currentLodLevel", KX_GameObject, m_currentLodLevel), KX_PYATTRIBUTE_RO_FUNCTION("name", KX_GameObject, pyattr_get_name), KX_PYATTRIBUTE_RO_FUNCTION("parent", KX_GameObject, pyattr_get_parent), KX_PYATTRIBUTE_RO_FUNCTION("groupMembers", KX_GameObject, pyattr_get_group_members), diff --git a/source/gameengine/Ketsji/KX_GameObject.h b/source/gameengine/Ketsji/KX_GameObject.h index 5800cbc6834..7d1a934bcec 100644 --- a/source/gameengine/Ketsji/KX_GameObject.h +++ b/source/gameengine/Ketsji/KX_GameObject.h @@ -88,6 +88,7 @@ protected: int m_layer; std::vector m_meshes; std::vector m_lodmeshes; + int m_currentLodLevel; SG_QList m_meshSlots; // head of mesh slots of this struct Object* m_pBlenderObject; struct Object* m_pBlenderGroupObject; -- cgit v1.2.3
