DirectXでロックオンカメラの実装

[こたん]

ロックオンカメラを実装したいと思っています。
現在敵1 player1でLを押したらロックオンをするようにしています
下記はCameraUpdate内のプログラムです
いろいろなサイトをみてやってみたのですがうまくいきません
なにかヒントでもあれば教えていただきたいです

コード:

m_lookAt = (m_front * LOOKATRANGE) + m_pos;

	this->UpdateView();

	m_pos.m128_f32[0] = m_lookAt.m128_f32[0] - m_front.m128_f32[0] * LOOKATRANGE;
	m_pos.m128_f32[1] = m_lookAt.m128_f32[1] - m_front.m128_f32[1] * LOOKATRANGE;
	m_pos.m128_f32[2] = m_lookAt.m128_f32[2] - m_front.m128_f32[2] * LOOKATRANGE;


	//注視転回点するでござる
	if (CKeyInput::GetKeyPress('Q')) {
		m_roteAngle -= 0.05;
		CScene::m_pLibMgr->m_pObjMgr->GetPlayer()->angle -= 0.05f;

		m_roteMat = XMMatrixRotationY(m_roteAngle);
		m_SubstitutePos = XMVector3TransformCoord(m_SubstitutePos, m_roteMat);
		m_front = XMVector3TransformNormal(m_front, m_roteMat);
		m_right = XMVector3Cross(m_front, m_eye_up);
	}

	if (CKeyInput::GetKeyPress('E')) {
		m_roteAngle += 0.05;
		CScene::m_pLibMgr->m_pObjMgr->GetPlayer()->angle += 0.05f;

		m_roteMat = XMMatrixRotationY(m_roteAngle);
		m_SubstitutePos = XMVector3TransformCoord(m_SubstitutePos, m_roteMat);
		m_front = XMVector3TransformNormal(m_front, m_roteMat);
		m_right = XMVector3Cross(m_front, m_eye_up);

	}
	
	if (CKeyInput::GetKeyPress('K')) {
		m_LockOn = true;
	}
	if (CKeyInput::GetKeyPress('J')) {
		m_LockOn = false;
	}

	XMVECTOR targetVec = XMVectorSet(0,0,0,1);

	if (m_LockOn) {
		CGolem* enemy;
		enemy = CScene::m_pLibMgr->m_pObjMgr->GetGameObject<CGolem>();
		
		CPlayer  *player;
		player = CScene::m_pLibMgr->m_pObjMgr->GetGameObject<CPlayer>();

		targetVec = enemy->m_pMyModel->m_pos  - player->m_pMyModel->m_pos;
		targetVec = XMVector3Normalize(targetVec);

		//angle = atan2(targetVec.m128_f32[0], targetVec.m128_f32[2]) + PI;
		//mat = XMMatrixRotationY(angle);

		//targetVec = XMVector3TransformCoord(targetVec, mat);

	}
	
	//if (!m_LockOn) {
		m_pos.m128_f32[0] = CScene::m_pLibMgr->m_pObjMgr->GetPlayer()->m_pos.m128_f32[0] + m_SubstitutePos.m128_f32[0] + targetVec.m128_f32[0];
		m_pos.m128_f32[1] = CScene::m_pLibMgr->m_pObjMgr->GetPlayer()->m_pos.m128_f32[1] + m_SubstitutePos.m128_f32[1];
		m_pos.m128_f32[2] = CScene::m_pLibMgr->m_pObjMgr->GetPlayer()->m_pos.m128_f32[2] + m_SubstitutePos.m128_f32[2] + targetVec.m128_f32[2];
	//}
	/*else {
		m_pos.m128_f32[0] = CScene::m_pLibMgr->m_pObjMgr->GetPlayer()->m_pos.m128_f32[0] - targetVec.m128_f32[0];
		m_pos.m128_f32[1] = CScene::m_pLibMgr->m_pObjMgr->GetPlayer()->m_pos.m128_f32[1];
		m_pos.m128_f32[2] = CScene::m_pLibMgr->m_pObjMgr->GetPlayer()->m_pos.m128_f32[2] - targetVec.m128_f32[2];
	}*/

	m_lookAt.m128_f32[0] = CScene::m_pLibMgr->m_pObjMgr->GetPlayer()->m_pos.m128_f32[0] + targetVec.m128_f32[0];
	m_lookAt.m128_f32[1] = CScene::m_pLibMgr->m_pObjMgr->GetPlayer()->m_pos.m128_f32[1];
	m_lookAt.m128_f32[2] = CScene::m_pLibMgr->m_pObjMgr->GetPlayer()->m_pos.m128_f32[2] + targetVec.m128_f32[2];


	m_roteAngle = 0.0f;
