MOC的資料不多，目前僅限于以下幾處：
http://www.ogre3d.org/tikiwiki/Minimal+Ogre+Collision&structure=Librarieshttp://www.ogre3d.org/forums/viewtopic.php?t=45267http://sourceforge.net/projects/moc-collision/http://www.ogre3d.org/forums/viewtopic.php?t=23440http://code.google.com/p/minimal-ogre-collision-toolkit/moc代碼只有一個(gè)h和一個(gè)cpp文件，還算簡潔的。也是很多年沒有維護(hù)了，簡單用用也算夠了。
使用步驟
1、初始化
1
MOC::CollisionTools* mCollisionTools;
2// init the collision handler
3mCollisionTools = new CollisionTools(mSceneMgr, mArtifexLoader->mTerrainInfo);
4
5// set how far we want the camera to be above ground
6mCollisionTools->setHeightAdjust(4.5f);
7
8// place the camera node on the ground
9mCollisionTools->calculateY(mCamNode); 2、碰撞檢測
1
// calculate the new Y position: check vs. terrain & all objects flagged with ENTITY_MASK
2// multiple masks possible like e.g. ENTITY_MASK|MY_MASK|ETC_MASK
3// doGridCheck casts a 2nd ray, gridWidth=2.0f ogre units away from the exact camera position to
4// avoid falling through small wholes or gaps in hangbridges for example.
5mCollisionTools->calculateY(mCamNode,true,true,2.0f,ENTITY_MASK);
6
7// check if we are colliding with anything with a collision radius of 2.5 ogre units and we
8// set the ray origin -1.0 lower towards the ground to get smaller obstacles too
9if (mCollisionTools->collidesWithEntity(oldPos, mCamNode->getPosition(), 2.5f, -1.0f, ENTITY_MASK))
10
{
11
// undo move
12 mCamNode->setPosition(oldPos);
13
} 3、鼠標(biāo)拾取，射線查詢
1void SampleApp::pickEntity(const OIS::MouseEvent &arg, const Ogre::uint32 queryMask)
2{
3 Entity *tmpE = NULL;
4 Vector3 result = Vector3::ZERO;
5 float distToColl;
6 if (mCollisionTools->raycastFromCamera(mRenderWin, mCamera, arg, result, (ulong&)tmpE, distToColl, queryMask))
7
{
8 SceneNode* node = tmpE->getParentSceneNode();
9 if (node->getShowBoundingBox())
10 {
11 node->showBoundingBox(false);
12
} else
13 {
14 node->showBoundingBox(true);
15 }
16 }
17}
18
19bool SampleApp::mousePressed(const OIS::MouseEvent &arg, OIS::MouseButtonID id)
20{
21 if ( id == OIS::MB_Left )
22 {
23 mLMouseDown = true;
24 pickEntity(arg, ENTITY_MASK);
25 }
26} 4、清理
delete mCollisionTools; 5、中文資料
