Problems with creating spectator camera with C++

[Lostghbear]

Hello!

I have problems with creating spectator camera with C++ using this tutorial

 

sphere moving faster then camera, but this is not main problem.

I dont understand why, but sphere have the inertia. I mean, when i stop pressing 'w' sphere dont stop movement, just slow down a bit. And also she pushes off from the wall and flies.

 

I cant understand why it hapends! Please, give me advice. There is my code

 

_{#include "App.h"}

_{using namespace Leadwerks;}

_{App::App() : window(NULL), context(NULL), world(NULL), camera(NULL) {}}

_{App::~App() { delete world; delete window; }}

_{Vec3 camRotation;}

_{Vec2 centerMouse;}

_{Vec2 mouseDef;}

_{Vec3 camMovement;}

_{Vec3 Temp;}

_{float MouseSens;}

_{float strafeM;}

_{float moveM;}

_{float forceM;}

_{bool cameraMode;}

_{bool App::Start()}

_{

_{// Создание основных коммпонентов}

_{window = Window::Create("Learning", 0, 0, 1920, 1080, Window::Titlebar);}

_{context = Context::Create(window);}

_{world = World::Create();}

_{camera = Camera::Create();}

_{camera->SetPosition(0, 2, 5);}

_{light = DirectionalLight::Create();}

 

_{// Определение переменных}

_{MouseSens = 10;}

_{strafeM = 0.4;}

_{moveM = 0.6;}

_{forceM = 1000;}

_{centerMouse = Vec2(context->GetWidth() / 2, context->GetHeight() / 2);}

 

_{// Создание спектатора}

 

_{spectator = Model::Sphere(8);}

_{spectator->SetPosition(Vec3(0, 8, 0));}

_{spectator->SetScale(Vec3(5, 5, 5));}

_{Shape* spectatorShape = Shape::Sphere(0, 0, 0, 0, 0, 0, 1, 1, 1);}

_{spectatorShape = Shape::Sphere();}

_{spectator->SetShape(spectatorShape);}

_{spectator->SetMass(1);}

_{spectator->SetGravityMode(false);}

_{spectatorShape->Release();}

_{cameraMode = false;}

_{// Загрузка карты}

_{Map::Load("maps/test.map");}

_{window->HideMouse();}

 

_{return true;}

_}

_{bool App::Loop()}

_{

_{Time::Update();}

_{world->Update();}

_{world->Render();}

_{context->Sync(false);}

_{// Возможность закрыть окно}

_{if (window->Closed() || window->KeyHit(Key::Escape))}

_{return false;}

_{// Переключение между режимами камеры}

_{if (window->KeyHit(Key:))}

_{cameraMode = !cameraMode;}

 

_{// Удерживание указателя мыши по центру}

_{Vec3 CMP = window->GetMousePosition();}

_{mouseDef.x = CMP.x - centerMouse.x;}

_{mouseDef.y = CMP.y - centerMouse.y;}

_{window->SetMousePosition(centerMouse.x, centerMouse.y);}

_{// Вращение камеры}

_{camRotation.x += mouseDef.y / MouseSens;}

_{camRotation.y += mouseDef.x / MouseSens;}

_{camera->SetRotation(camRotation);}

_{//Движение камеры}

_{camMovement.x = (window->KeyDown(Key:) - window->KeyDown(Key::A)) * Time::GetSpeed() * strafeM;}

_{camMovement.y = (window->KeyDown(Key::E) - window->KeyDown(Key::Q)) * Time::GetSpeed() * strafeM;}

_{camMovement.z = (window->KeyDown(Key::W) - window->KeyDown(Key::S)) * Time::GetSpeed() * moveM;}

 

_{if (cameraMode)}

_{

 

_{camera->SetPosition(spectator->GetPosition());}

_{Vec3 tForce = Transform::Vector(camMovement, camera, 0);}

_{spectator->AddForce(camMovement * forceM);}

_}

_else

_{

_{camera->Move(camMovement);}

_};

_{return true;}

_}

The sphere has inertia because you are adding a force to move it.

 

You could use the SetVelocity() command instead, which will set the speed.

Hmm...Now there is no any inertia, but spectator not works. I mean, i can go throw walls and other stuff. Weird, in tutorial Jorn using force, and all working perfect.
