Here the current Camera Dolly Component i created. It consists of 2 Components. The Camera Dolly Component itself. The Camera Dolly Event Component. Usage Extract and place it into your `Souce/Components` directory. Add a Camera to your Scene. Add a "Empty" Node to your scene that will contain the Camera Spline Path. Add "Empty" Nodes inside this CameraPath node that defines the path the camera will move along. (takes the rotation into account as well as long as no "Point Camera At" node is selected. Name each "Empty" Node path point "p1", "p2", "p3" and so forth. (subject to change) and order the nodes accordingly. At the end this should look something like this in your Scene list: In the Camera itself with the CameraDolly component added, select the CameraPath node and optionally a node where the camera should point at. If you want to do something as soon as the Camera reaches a point along the path, add the CameraDollyEvent Component to one of the path nodes and add it to the Flowgraph. Todo and known issues The order of nodes in the Editor is not always the same as returned by the API (see https://www.ultraengine.com/community/topic/65647-moving-entities-in-editor-looses-order-and-cannot-be-moved-to-top/ ) Its difficult to determine the rotation of points without visualisation. Its difficult to guess the path the camera takes along the spline without visualisation. Movement speed is not yet Update thread independent. (unlikely but possible, still thanks to Josh for adding `World:GetSpeed()`). Rotation might not work (see https://www.ultraengine.com/community/topic/65628-lua-entitygetrotation-always-returns-vec3-000/ ) Download CameraDolly.zip

Greetings!!! It's been many months since the last time I've worked with Leadwerks, the same months since I've been here. I hope you are all OK. This week I have resumed my project, and I have come face to face with a problem that I still cannot solve in my Leadwerks. And this is the using of "Render Target" in the Camera entity. Inside Leadwerks it works great, and the camera image renders fine when running the game. But publishing/exporting the game in a Standalone, when I run it the texture doesn't receive the image projected by the camera. I've kept searching on Google and here on the forum, and I still can't find an answer to my problem. Can someone help me, because I can't fix this problem that seems so simple... I've been dragging it for very long time and I'm not capable of making this work in Standalone. Many thanks!! Many thanks in advance!!

Hi there team!! I have one question i hope you can help me with... I have a level with only 2 cameras for show an animation prologue... Text and Images using POSTRENDER and context system works ok in CAMERA 1. But when i disable CAMERA1 and enable CAMERA2 for continue animation in another location of the map, TEXT and IMAGES don't appear on CAMERA 2... Anyone have any tip or idea why is this happening??? If you need more information ask me... I don't know how solve this... Thank you very much!!

Hey all, I'm playing with VR and I wanted to create something you'd find in Robo Recall in which the player can change the direction they want to face after a teleport. I did the becon rotating and it was all ready to go until I found out that no matter If I rotated the camera or player, OpenVR took priority on what was north south east and west. Is there a way to do this in lua and/or C++? I have a Oculus Rift with very limited play space so I wanted to have this feature for playing around.

Turning/Moving the camera in the perspective viewport stopped working for some reason. It whas working fine yesterday. This is using leadwerks 4.4. The things that do work is: Panning/Zooming (scroll wheel). The things that dont work anymore: Moving (ASWD). Up/Down (QE). Panning (Arrow Keys). Is this a bug or did i accidentally change a option somewhere? (i've tried changing some options in config but no changes)

Is there a way to rotate camera around the selection (selected object) in the editor? To observe selection from different directions. (I found only the free rotation mode (with right mouse button) which rotates camera around it`s own pivot)

I'm setting my camera based on my model's position/rotation but i'd like the camera to be positioned a little further back so i can actually see the model move, i think what i'm looking for is something like vector forward. Right now, i'm setting it at the exact same x/z coordinates. Vec3 pos = player_entity->model->GetPosition(); camera->SetPosition(Vec3(pos.x, pos.y + 2, pos.z)); What would be required to re-calculate the new x/z coordinates of the camera?

This function does not work (camera->SetViewport). Please tell me a replacement. On a single screen must be two cameras. I am using C ++.

Hey guys, Yet another issue I'm faced with, and is probably real simple to accomplish but I can't seem to understand how to do it. How do I add a Post-Processing shader to my work? Not a single model, but to the entire level? Thanks in advance!

I have done quite a bit of snooping about, on the forums and going through the tutorials on YouTube, the complete series done by Jorn Theunisen is old and I understand some parts are outdated. Keeping in mind I'm not a programmer though I can read it fairly well just cannot write it, has anyone developed a rpg style 3rd person camera script? Not sure what I'm referring to a example is, Skyrim or even WOW, where the camera follows and has collision detection so it does not drift through walls, and you can rotate around it with the right mouse button. I'm sure there are developers out there who know exactly what type of setup I'm referring to Any help would be appreciated.

if window:MouseHit(1) then local pickinfo= PickInfo() local p1 = Window:GetCurrent():GetMousePosition() --local box = Model:Box() if (self.camera:Pick(p1.x,p1.y,pickinfo,0.5,true)) then if pickinfo.entity then if pickinfo.entity:GetKeyValue("Button")~="" then --box:SetScale(0.2,0.2,0.2) --box:SetPosition(pickinfo.entity:GetPosition(true),true) System:Print(tostring(pickinfo.entity:GetKeyValue("Button"))) end end end end the above is the camera pick , I cant find anything . The camera pick should Print the Key value of the box in the script below. However, it prints nothing and I dont know why. Script.localKeyValue = -1--string " Key Value Integer" function Script:Start() self.entity:SetKeyValue("Button",self.localKeyValue) end

I have a third person character controller, the character has pickmode(0). I can walk around and have obstacles between the player and the cam , but nothing happens? the self.pivot is a pivot which is at the center of the character (the camera focus). updateworld: if self.entity.world:Pick(self.pivot:GetPosition(),self.camera:GetPosition(),pickinfo,0,true) then local model2 = Model:Box() model2:SetPickMode(0) model2:SetPosition(pickinfo.position) model2:SetColor(0,1,0) System:Print(">> PICKED") --self.camera:SetPosition(pickinfo.position) end

Hello there, I have 2 questions and any help / idea is welcome. 1. How can I make sure that the camera does not go off terrain? 2. I need to move the camera forward (0Z) and sidewards (0X) along it's own axes, but without taking in consideration the rotation around 0Y axis (up/down). Any idea? I tried to make some pictures, hope they help: and an example: PS: I have solutions for both problems, but I am not satisfied with them. 1. "trap" the camera inside a cube 2. increment the camera position with sin(y rotation) on 0X, and with cos(y rotation) on 0Z code below: PPS: It didn't take the whitespaces when I copy-pasted from VS. Any idea how to solve this? PSPS: I posted the camera movement method on pastebin: http://pastebin.com/BLBQgjAj

Please consider this piece of code: #include "App.h" App::App() : window(NULL), context(NULL), world(NULL), camera(NULL) { } App::~App() { delete world; delete window; } Leadwerks::Model *model = NULL; bool App::Start() { window = Leadwerks::Window::Create(); context = Leadwerks::Context::Create(window); world = Leadwerks::World::Create(); camera = Leadwerks::Camera::Create(); camera->Move(0, 0, -3); Leadwerks::Light *light = Leadwerks::DirectionalLight::Create(); light->SetRotation(35, 35, 0); model = Leadwerks::Model::Box(); model->SetColor(0.0, 0.0, 1.0); return true; } bool App::Loop() { if (window->Closed() || window->KeyDown(Leadwerks::Key::Escape)) return false; if (camera) if (window->KeyDown(Leadwerks::Key::Space)) { camera->Release(); // or camera->Hide() camera = NULL; } model->Turn(0, Leadwerks::Time::GetSpeed(), 0); Leadwerks::Time::Update(); world->Update(); world->Render(); context->Sync(); return true; } After pressing the space key, only a blank black screen should be visible. But strangely the cube is still visible, without rotating. How I can have the 3D world invisible when the camera is deleted?

Hello forum, I am trying to make my camera move along some 3D points that also store rotation How can I make the movement smooth like in a spline? I don't know much about splines but found this for leadwerks 2: How can I do sth. like that on Leadwerks 3? thanks for your help! yours Max Aigner

Just had a question with whether it is possible to make a dynamic scope for a weapon using the Camera Entity. I have the camera mounted in front of the scope of the weapon in the prefab and set the Render target on the scopes .tex. Inside the editor it seems to be working but in game the scope is just black. I have no idea if this was at all possible just gave it a shot. Any ideas would be awesome!

Hello Leadwerks community, This is my first post and I was wondering if anyone out there is able to help me create a simple script. As the title states, I just want to get a simple script, like the FPS controller one, however, just for walking around. Thanks.

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; }

Alright, this seems like a pretty important issue to me. As it is desirable and expected, directional light shadows are culled (not showed/displayed) when the camera is far away from the object: it has to be within the range of 30m or so, as I've seen so far, in order that shadows get rendered (at least with default light quality). However, when camera is set far away from the object, but zooms in so that it appears very near to the object, shadows are not rendered either. If you think about it, that is a highly unrealistic behavior: Imagine a camera that simulates binoculars. If we look through our binoculars, we are supposed to see the object as if it was near us. In that case, we would see shadows it casts if it is lit by the sun, no matter how far away our binoculars from the object actually are. However, with current LE settings it seems not possible to set cast shadow rendering distance based on the camera zoom level (I'm not sure if it's possible at all, btw - I've read some past threads and no one seems to give a definitive answer). So, a simple improvment on the shadow culling calculation - which would consist in inclusion of dividing camera distance by its zoom level - would be an easy modifcation and more than welcome. At least, IMO. P.S. I've tried setting light's quality to max. It does not solve the issue.

When I try to change a camera mode to Camera.Ortographic, I get a "error in function 'SetProjectionMode'.; argument #2 is 'nil'; 'number' expected." function Script:UpdateWorld() if (window:KeyHit(Key.Space)) then if (self.entity:GetProjectionMode()==Camera.Orthographic) then self.entity:SetProjectionMode(Camera.Perspective) self.entity:SetZoom(1) else self.entity:SetProjectionMode(Camera.Ortographic) self.entity:SetZoom(1) end end end

Hello! So i am not sure if this is an actual bug or not, if not I apologize. but the issue that i am running into is sometimes when i start Leadwerks i am not able to move my camera as I normally am, for example I can not use the right click to turn or use wasd to move or e and q to go up and down which really limits how quickly i can edit the map. Is there some option that controls this? Or am i having a weird bug? Any help with this will be much appreciated!

Line 10 Script.playerHeight = 1.8 --float "Player Height" Line 86 --local playerTempHeight = ((self:IsCrouched() == 1) and crouchHeight or playerHeight)

I'm implementing a camera picking with this code if (window:MouseHit(1)) then local pickinfo = PickInfo() if (self.camera:Pick(context:GetWidth() / 2, context:GetHeight() / 2, pickinfo, 0, true)) then System:Print(pickinfo.position.z) end end and I'm getting really wierd results concerning the pickinfo.position.z (x and y are correct). Here they are This happens only when I'm picking the cube (CSG, but happens with models as well) from the frontside, that is, when I'm facing in the positive z axis direction. When I slowly move the mouse and do the picking, I get different results (already impossible, since the cube side is aligned with the x axis) with impossible values... EDIT: It seems that it happens only when the side of the cube is aligned with the x = 0. Could it be a bug?

While trying to getting a camera present in a Map from the C++ side, I found there is 2 cameras (according to world->cameras.size(). What is the second camera ? How leadweaks choose the camera to render the scene ?

So after making my model and revision it 2 times I cant figure out why when I import it and place a fps camera in it. When the game starts the forward position is off and the camera shows above the player model. I do want the camera in third person but I want to be able to have it not controlling it backwards.
