[how to access Map Components?]

 

How do I access the camera in C++ when loading the map start.ultra? The hang is created in the ThirdPersonControls component and attached to the players. Is there a command for this or is it just a roundabout way?

Kind regards, Norbert

 

 

[UltraEngine.h not found]

 

Hello, I have just installed the UltraEngine. After creating a project, I open the test.sln in the editor. It starts Visual Studio 2022. When I now want to test the program I get the error message > Error (active) E1696 The file "Source" cannot be opened: "UltraEngine.h".

Is anyone able to help me? Thanks

[Can i render a model that is not in camaera range ?]

Thank you.

Very bad. as even in openb3d and minib3d has that opportunity. well the model is outside the maximum range camera.

[Entity::Point Memory Leak c++]

Hello,

 

if i use the point function and context->Sync(false) the memory usage increases continuously.

 

As an example, we take the sample code:

 

The only change is the (context->Sync(false))

 

 

 

#include "App.h"
using namespace Leadwerks;
App::App() : window(NULL), context(NULL), world(NULL), camera(NULL) {}
App::~App() { delete world; delete window; }
Entity* entity1 = NULL;
Entity* entity2 = NULL;
bool App::Start()
{
 window = Window::Create();
 context = Context::Create(window);
 world = World::Create();
 camera = Camera::Create();
 camera->Move(0,1,-3);
 Light* light = DirectionalLight::Create();
 light->SetRotation(35,35,0);

 //Create a model
 entity1 = Model::Box();
 entity1->SetColor(0.0,0.0,1.0);
 entity1->SetRotation(0,-90,0);

//Create another model to point at the one that goes in circles
 entity2 = Model::Box();
 entity2->SetColor(0.0,1.0,0.0);
 entity2->SetPosition(0,0,2);

 return true;
}
bool App::Loop()
{
 if (window->Closed() || window->KeyDown(Key::Escape)) return false;

 //Make the model move in a circle
 entity1->Turn(0,Time::GetSpeed()*0.5,0);
 entity1->Move(0,0,0.1);

//Point this at the moving box when the space key is pressed
if (window->KeyDown(Key::Space))
{
 entity2->Point(entity1,2,Time::GetSpeed()*0.1);
}

 Time::Update();
 world->Update();
 world->Render();
 context->Sync(false);

 return true;
}

[Windows 10?]

hi,

 

with the latest video card drivers from ATI, I have now no more problems with Leadwerks. for now. (windows 10)

[Windows 10?]

hi,

 

Do not install Windows 10 if you have an ATI.

 

Today I updated to Windows 10 and now the models are gone. ATI Driver bug ?

[New AMD driver - Models not rendering]

Same Problem on ATI R9 270x.

 

had the beta drivers installed on Windows 7 and everything was ok. Now today I updated to Windows 10 and now the models are gone. because there is only one driver for Windows 10.

[FileSystem::GetFileSize allways return 0 it's a bug? or my mistake?]

Hi,

 

System::Print(Filesystem::GetFileSize("steam_appid.txt"));

 

return always 0;

 

System::Print(FileSystem::GetFileType("steam_appid.txt"));

 

but return 1 by GetFileType so the file is still there ?

 

have the problem with each file.

 

it's a bug? or my mistake?

 

working under Windows. 7 and c++.

 

Does anyone have the same problem?

 

thanks norbert

[Problem with virtual light calculation in the shader]

So the problem was solved .... I think ....

 

Changes in vertex shader:

 

// My Code

vec3 lightVec2 = normalize(LightPos-vec3(modelvertexposition));

mat3 normalMatrix = transpose(inverse(mat3(entitymatrix_)));

vec3 Normal2 = normalMatrix * vertex_normal;

Light_Intensity = max(dot(Normal2, lightVec2), 0.0)*10;

[Problem with virtual light calculation in the shader]

Hello There,

 

I want to let light a sphere with a virtual light. For that I have adapted a shader. But the problem is that the beam moved on the sphere.

 

maybe could give me yes explain what I'm doing wrong someone.

Hi Rick,

 

you can do so if I have understood the question correctly.

ok the error is gone.think that was my mistake.

[LE3 Indie Edition [ Questions ]]

Hello Georjack,

 

1. You can save and load your game state. you must write your own loader with this commands -->

http://www.leadwerks.com/werkspace/page/documentation/_/command-reference/stream/

 

2. Yes you can create a simple gui by use the context commads-->

http://www.leadwerks.com/werkspace/page/documentation/_/command-reference/context/

 

3. A Exe is included but the lua code ist not encrypted and everyone can read it.

I have read but I think that this may soon be encrypted with leadwerks. if not you can use MoleBox indeed.

 

4 and 5, I can not help you.

I would like generating a second world. with a camera from the second world I want to render in the skybox from the first world.

[how i can i draw in a cubemap ?]

hi shadmar,

 

I want to draw in the skybox cubemap in realtime.

 

when i draw to position 0,0 self.context:DrawImage(self.sample,0,0)

 

the green texture is visible but on other coordinates it has no effect.

 

greeting norbert

 

[how i can i draw in a cubemap ?]

I would like to draw a image in the skybox cubemap.

But has only a effect when i draw the image at position 0,0

all others has no effect.

 

in function App:Start()

iam create the skybox

--Create skybox
sky = Model:Create()
--just render a plane and project cubemap onto it
local surface = sky:AddSurface()
surface:AddVertex(-0.5,-0.5,0, 0,0,-1)
surface:AddVertex(0.5,-0.5,0, 0,0,-1)
surface:AddVertex(0.5,0.5,0, 0,0,-1)
surface:AddVertex(-0.5,0.5,0, 0,0,-1)
surface:AddTriangle(2,1,0)
surface:AddTriangle(0,3,2)

--position in front of camera but far out to near camera clip plane
sky:SetPosition(self.FPS_CAM:GetPosition())
sky:SetRotation(self.FPS_CAM:GetRotation())
sky:Move(0,0,self.FPS_CAM:GetRange().y-50)
sky:SetScale(self.FPS_CAM:GetRange().y*10)
sky:SetParent(self.FPS_CAM)

-- and paint it
skymat=Material:Load("Materials/Sky/myskybox1.mat")
sky:SetMaterial(skymat)



self.skytexture = skymat:GetTexture()
self.FPSbuffer = Buffer:Create(2048,1536,1,0,0)
self.FPSbuffer:SetColorTexture(self.skytexture)

 

in function App:Loop()


self.FPSbuffer:Enable()
self.FPSbuffer:Clear()
self.context:DrawImage(self.sample,0,0)
self.FPSbuffer:Disable()

 

 

there is an extra command to sign in a cubemap?

have seen there is also an extra shader.
