Hello I have just got Ultra Engine and have not got it to compile yet. I added missing ATL modules inside visual studio installer, made a new c++ project multiple times and set the optimization to disabled in the project settings. Need help at fixing these errors. The Project is called StereoWindow and i have the exact same problem with another project.

I feel like a noob. How do I import a 3D asset (Glib) into Ultra Engine? I'm just testing the engine now that I installed it. Everything is running nicely, but after converting a simple asset to Glib, I cannot find a way to import it. Is there a batch import feature? I seem to remember Leadwerks being able to do that. I have tons of assets and importing them one-by-one would be a pain. Thank you. Mike

In full 2D works fine but in 3D it's a black background in Pixmap area where should be transparent pixels. Probably Vulkan things this time too? Just want to be sure if it will be fixed later in Ultra or i'm missing something. #include "UltraEngine.h" using namespace UltraEngine; void drawPixel(shared_ptr<Pixmap> pixmap, const int x, const int y, unsigned int color) { if (pixmap && x >= 0 && x < pixmap->size.width && y >= 0 && y < pixmap->size.height) { pixmap->WritePixel(x, y, color); } } void drawCircle(shared_ptr<Pixmap> pixmap, const int centerX, const int centerY, const int radius, unsigned int color) { int x = 0; int y = radius; int delta = 1 - 2 * radius; int error = 0; while (y >= 0) { drawPixel(pixmap, centerX + x, centerY + y, color); drawPixel(pixmap, centerX + x, centerY - y, color); drawPixel(pixmap, centerX - x, centerY + y, color); drawPixel(pixmap, centerX - x, centerY - y, color); error = 2 * (delta + y) - 1; if (delta < 0 && error <= 0) { ++x; delta += 2 * x + 1; continue; } error = 2 * (delta - x) - 1; if (delta > 0 && error > 0) { --y; delta += 1 - 2 * y; continue; } ++x; delta += 2 * (x - y); --y; } } int main(int argc, const char* argv[]) { auto displays = GetDisplays(); auto window = CreateWindow("Ultra Engine", 0, 0, 1280, 720, displays[0], WINDOW_CENTER | WINDOW_TITLEBAR); auto world = CreateWorld(); auto framebuffer = CreateFramebuffer(window); auto camera = CreateCamera(world); camera->SetClearColor(0.125); camera->SetFov(70); camera->SetPosition(0, 0, -3); auto default_font = LoadFont("Fonts\\arial.ttf"); auto ui = CreateInterface(world, default_font, framebuffer->GetSize()); ui->SetRenderLayers(2); ui->root->SetColor(0.0f, 0.0f, 0.0f, 0.0f); auto ui_camera = CreateCamera(world, PROJECTION_ORTHOGRAPHIC); ui_camera->SetPosition((float)framebuffer->GetSize().x * 0.5f, (float)framebuffer->GetSize().y * 0.5f, 0); ui_camera->SetRenderLayers(2); ui_camera->SetClearMode(CLEAR_DEPTH); auto panel = CreatePanel(0, 0, 200, 200, ui->root); auto pixmap = UltraEngine::CreatePixmap(100, 100); drawCircle(pixmap, 50, 50, 25, Rgba(100, 50, 150, 255)); panel->SetPixmap(pixmap); panel->SetColor(0.1f, 0.15f, 0.1f, 1); while (window->Closed() == false and window->KeyDown(KEY_ESCAPE) == false) { while (PeekEvent()) { auto ev = WaitEvent(); ui->ProcessEvent(ev); } world->Update(); world->Render(framebuffer); } return 0; }

Painting working only before first Render() #include "UltraEngine.h" using namespace UltraEngine; shared_ptr<Window> window; shared_ptr<Framebuffer> framebuffer; shared_ptr<World> menuWold; shared_ptr<Interface> ui; shared_ptr<Camera> uiCamera; shared_ptr<Widget> drawPanel; shared_ptr<Widget> btn; shared_ptr<Pixmap> px; int progress = 0; void paint() { progress++; for (int x = 0; x < progress * 10; x++) { for (int y = 0; y < 200; y++) { px->WritePixel(x, y, Rgba (20, 250, 10)); } } } void initGui() { auto default_font = LoadFont("Fonts\\arial.ttf"); ui = CreateInterface(menuWold, default_font, framebuffer->GetSize()); ui->SetRenderLayers(2); ui->root->SetColor(0.0f, 0.0f, 0.0f, 0.0f); uiCamera = CreateCamera(menuWold, PROJECTION_ORTHOGRAPHIC); uiCamera->SetPosition((float)framebuffer->GetSize().x * 0.5f, (float)framebuffer->GetSize().y * 0.5f, 0); uiCamera->SetRenderLayers(2); uiCamera->SetClearMode(CLEAR_DEPTH); drawPanel = CreatePanel(0, 50, 200, 200 , ui->root, PANEL_DEFAULT); drawPanel->SetColor(1, 0, 0); px = CreatePixmap(200, 200); drawPanel->SetPixmap(px); btn = CreateButton("Progress", 0, 0, 100, 20, ui->root); //works for (int i = 0; i < 5; i++) { paint(); } } int main(int argc, const char* argv[]) { //Get the displays auto displays = GetDisplays(); //Create a window window = CreateWindow("Ultra Engine", 0, 0, 1000, 1000, displays[0], WINDOW_DEFAULT); //Create a world menuWold = CreateWorld(); //Create a framebuffer framebuffer = CreateFramebuffer(window); //Create light auto light = CreateBoxLight(menuWold); light->SetRange(-10, 10); light->SetRotation(15, 15, 0); light->SetColor(2); //Create camera auto camera = CreateCamera(menuWold); camera->SetClearColor(0.125); camera->SetPosition(0, 0, -3); camera->SetFov(70); //Create scenery auto box = CreateBox(menuWold); initGui(); //Main loop while (window->Closed() == false and window->KeyDown(KEY_ESCAPE) == false) { while (PeekEvent()) { const Event ev = WaitEvent(); if (ev.source == btn && ev.id == EVENT_WIDGETACTION) { //pixmap not changes paint(); } ui->ProcessEvent(ev); } menuWold->Update(); menuWold->Render(framebuffer); } return 0; }

This works in 2D UI but in 3D widget became not interactive but visible. Maybe where is another way to delete widgets in 3D UI? #include "UltraEngine.h" using namespace UltraEngine; int main(int argc, const char* argv[]) { auto displays = GetDisplays(); auto window = CreateWindow("Ultra Engine", 0, 0, 1280, 720, displays[0], WINDOW_CENTER | WINDOW_TITLEBAR); auto world = CreateWorld(); auto framebuffer = CreateFramebuffer(window); auto camera = CreateCamera(world); camera->SetClearColor(0.125); camera->SetFov(70); camera->SetPosition(0, 0, -3); auto default_font = LoadFont("Fonts\\arial.ttf"); auto ui = CreateInterface(world, default_font, framebuffer->GetSize()); ui->SetRenderLayers(2); ui->root->SetColor(0.0f, 0.0f, 0.0f, 0.0f); auto ui_camera = CreateCamera(world, PROJECTION_ORTHOGRAPHIC); ui_camera->SetPosition((float)framebuffer->GetSize().x * 0.5f, (float)framebuffer->GetSize().y * 0.5f, 0); ui_camera->SetRenderLayers(2); ui_camera->SetClearMode(CLEAR_DEPTH); auto button = CreateButton("Button", 10, 10, 120, 30, ui->root); while (window->Closed() == false and window->KeyDown(KEY_ESCAPE) == false) { while (PeekEvent()) { const Event ev = WaitEvent(); if (ev.source == button && ev.id == EVENT_WIDGETACTION) { button->SetParent(NULL); } ui->ProcessEvent(ev); } world->Update(); world->Render(framebuffer); } return 0; }

NavMesh can't be seen (with setDebuggint(true)) or used if you use brushes as a scene instead of models. #include "UltraEngine.h" using namespace UltraEngine; int main(int argc, const char* argv[]) { //Get the displays auto displays = GetDisplays(); //Create a window auto window = CreateWindow("Ultra Engine", 0, 0, 1280, 720, displays[0], WINDOW_CENTER | WINDOW_TITLEBAR); //Create a framebuffer auto framebuffer = CreateFramebuffer(window); //Create a world auto world = CreateWorld(); //Create a camera auto camera = CreateCamera(world); camera->SetFov(70); camera->SetClearColor(0.125); camera->SetPosition(0, 3, -6); camera->SetRotation(35, 0, 0); //Create light auto light = CreateBoxLight(world); light->SetRange(-20, 20); light->SetArea(20, 20); light->SetRotation(35, 35, 0); light->SetColor(3); //Create scene //auto ground = CreateBox(world, 10, 1, 10); //ground->SetPosition(0, -0.5, 0); //ground->SetColor(0, 1, 0); //auto wall = CreateBox(world, 1, 2, 4); float w = 10, h = 1, d = 10; auto brush = CreateBrush(world); //Add brush vertices brush->AddVertex(w * 0.5, 0, d * 0.5); brush->AddVertex(-w * 0.5, 0, d * 0.5); brush->AddVertex(-w * 0.5, 0, -d * 0.5); brush->AddVertex(w * 0.5, 0, -d * 0.5); brush->AddVertex(w * 0.5, -h, d * 0.5); brush->AddVertex(-w * 0.5, -h, d * 0.5); brush->AddVertex(-w * 0.5, -h, -d * 0.5); brush->AddVertex(w * 0.5, -h, -d * 0.5); //Add faces auto face = brush->AddFace(); face->AddIndice(0); face->AddIndice(1); face->AddIndice(2); face->AddIndice(3); face = brush->AddFace(); face->AddIndice(4); face->AddIndice(5); face->AddIndice(6); face->AddIndice(7); face = brush->AddFace(); face->AddIndice(0); face->AddIndice(1); face->AddIndice(5); face->AddIndice(4); face = brush->AddFace(); face->AddIndice(2); face->AddIndice(3); face->AddIndice(7); face->AddIndice(6); face = brush->AddFace(); face->AddIndice(1); face->AddIndice(2); face->AddIndice(6); face->AddIndice(5); face = brush->AddFace(); face->AddIndice(0); face->AddIndice(3); face->AddIndice(7); face->AddIndice(4); brush->Build(); //Create navmesh auto navmesh = CreateNavMesh(world, 10, 5, 10, 4, 4); navmesh->SetDebugging(true); navmesh->Build(); //Create player auto player = CreateCylinder(world, 0.4, 1.8); player->SetColor(0, 0, 1); auto agent = CreateNavAgent(navmesh); player->Attach(agent); //Main loop while (window->Closed() == false and window->KeyDown(KEY_ESCAPE) == false) { if (window->MouseHit(MOUSE_LEFT)) { auto mousepos = window->GetMousePosition(); auto rayinfo = camera->Pick(framebuffer, mousepos.x, mousepos.y); if (rayinfo.success) { agent->Navigate(rayinfo.position); } } world->Update(); world->Render(framebuffer); } return 0; }

I think block.SetPixmap work fine if a pixmap as member set in but with if it's another pixmap (to make few different icons for different blocks) i have an exception at Render().

I changed CameraControls component to be tactical/isometric and noticed it's ignoring my new class member and in debug i found out it have vars that has been deleted and no my var there at all. My code Update() works fine tho except member issue. Tried to rebuild solution - nothing changes. Is there a proper way to recompile a component or maybe i should create new component instead of repurposing old one?

idk if there is another proper way to change a resolution of window. This way works in 2D UI. #include "UltraEngine.h" using namespace UltraEngine; bool EventCallback(const Event& ev, shared_ptr<Object> extra) { auto window = extra->As<Window>(); window->SetSize(1024, 768); return true; } int main(int argc, const char* argv[]) { auto displays = GetDisplays(); auto window = CreateWindow("Ultra Engine", 0, 0, 1280, 720, displays[0], WINDOW_CENTER | WINDOW_TITLEBAR); auto world = CreateWorld(); auto framebuffer = CreateFramebuffer(window); auto camera = CreateCamera(world); camera->SetClearColor(0.125); camera->SetFov(70); camera->SetPosition(0, 0, -3); auto default_font = LoadFont("Fonts\\arial.ttf"); auto ui = CreateInterface(world, default_font, framebuffer->GetSize()); ui->SetRenderLayers(2); ui->root->SetColor(0.0f, 0.0f, 0.0f, 0.0f); auto ui_camera = CreateCamera(world, PROJECTION_ORTHOGRAPHIC); ui_camera->SetPosition((float)framebuffer->GetSize().x * 0.5f, (float)framebuffer->GetSize().y * 0.5f, 0); ui_camera->SetRenderLayers(2); ui_camera->SetClearMode(CLEAR_DEPTH); auto btn = CreateButton("change res", 0, 0, 100, 30, ui->root); ListenEvent(EVENT_WIDGETACTION, btn, EventCallback, window); while (window->Closed() == false and window->KeyDown(KEY_ESCAPE) == false) { while (PeekEvent()) { auto ev = WaitEvent(); ui->ProcessEvent(ev); } world->Update(); world->Render(framebuffer); } return 0; }

Works fine in usual interface but throws an exception in case of UI in 3D rendering viewport. #include "UltraEngine.h" using namespace UltraEngine; int main(int argc, const char* argv[]) { //Get the displays auto displays = GetDisplays(); //Create a window auto window = CreateWindow("Ultra Engine", 0, 0, 640, 480, displays[0]); // Create a world auto world = CreateWorld(); // Create a framebuffer auto framebuffer = CreateFramebuffer(window); //Create ui camera auto uiCamera = CreateCamera(world, PROJECTION_ORTHOGRAPHIC); uiCamera->SetPosition(float(framebuffer->GetSize().x) * 0.5f, float(framebuffer->GetSize().y) * 0.5f, 0); uiCamera->SetRenderLayers(2); uiCamera->SetClearMode(CLEAR_DEPTH); //Load a font auto font = LoadFont("Fonts/arial.ttf"); //Create user interface auto ui = CreateInterface(world, font, framebuffer->GetSize()); ui->SetRenderLayers(2); ui->root->SetColor(0.0f, 0.0f, 0.0f, 0.0f); //Create widget auto sz = ui->root->ClientSize(); auto combobox = CreateComboBox((sz.x - 300) / 2, (sz.y - 30) / 2, 300, 30, ui->root); for (int n = 0; n < 20; ++n) { combobox->AddItem("Item " + String(n), n == 0); } while (true) { const Event ev = WaitEvent(); switch (ev.id) { case EVENT_WIDGETSELECT: Print("Item " + String(ev.data) + " selected"); break; case EVENT_WINDOWCLOSE: return 0; break; } } }

Works as intended in full 2D but if UI over 3D a text is not centerd vertically. #include "UltraEngine.h" using namespace UltraEngine; int main(int argc, const char* argv[]) { auto displays = GetDisplays(); auto window = CreateWindow("Ultra Engine", 0, 0, 1280, 720, displays[0], WINDOW_CENTER | WINDOW_TITLEBAR); auto world = CreateWorld(); auto framebuffer = CreateFramebuffer(window); auto camera = CreateCamera(world); camera->SetClearColor(0.125); camera->SetFov(70); camera->SetPosition(0, 0, -3); auto default_font = LoadFont("Fonts\\arial.ttf"); auto ui = CreateInterface(world, default_font, framebuffer->GetSize()); ui->SetRenderLayers(2); ui->root->SetColor(0.0f, 0.0f, 0.0f, 0.0f); auto ui_camera = CreateCamera(world, PROJECTION_ORTHOGRAPHIC); ui_camera->SetPosition((float)framebuffer->GetSize().x * 0.5f, (float)framebuffer->GetSize().y * 0.5f, 0); ui_camera->SetRenderLayers(2); ui_camera->SetClearMode(CLEAR_DEPTH); auto button = CreateButton("Button", 10, 10, 120, 30, ui->root); while (window->Closed() == false and window->KeyDown(KEY_ESCAPE) == false) { while (PeekEvent()) { auto ev = WaitEvent(); ui->ProcessEvent(ev); } world->Update(); world->Render(framebuffer); } return 0; } Same even if i'm using in custom widget textAlignment = TEXT_CENTER | TEXT_MIDDLE but text higher than center. Probably i'm missing something and cameras or something else should be configured differently in code.

I started using Ultra Engine on 2023-01-18. Learning to use the engine has been really easy. The documentation is very clear and I can search for keywords I want to learn about. Each command has a fully working example, so I can quickly copy-paste and try the code. The installer is also amazingly fast and automatic, and updating to the latest engine is just a click away. Updating my projects to use the latest version is also fully automatic by clicking on the yellow sign. The support from the Ultra team is very professional and fast, usually I got a solution and/or bug fix or new feature within minutes. Creating a new game project is just one click away, and when I organize my projects by moving them to other subfolders, importing them back is also a click away. Now I'm writing an actual game, and while doing so, I'm building classes to implement the game logic. I already made a model in Blender, and it worked directly in my game, using the glTF save option in Blender. Also the physics for the model worked directly. This weekend I'm unboxing my Ryzen 9 + Radeon RX6800 laptop, and setting everything up for art, music and game production. My tools are: - GIMP, for textures - Blender, for models - WavePad, for editing .flac audio files - Reaper, for composing music and saving as .flac - Ultra Engine, for making the game using the above assets The game will use physics for triggering game logic, for example: if a certain collision occurs, a new set of physics objects will be spawned. Some models will have animated color gradients, to simulate dream-like experiences, but who can tell if dreams are real when scientists say it is very probable that the universe is a simulation, made by Ultra Engine ;D Today I thought about binaural 3D sounds, they will occur when different physics materials collide. I will also implement sound occlusion, so that when a sound is played behind a wall, it will sound dampened. I even thought of sound reflection, so it would bounce off walls, possibly using an invisible gravityless physics ball or raytracing, but I can probably use reverb/echo effects instead. Finally, the scene will be streamed from a database, perhaps using SQLite3, and I found a nice trick how to remove far-away models using a C++ list. One thing I really like about the engine too, is that it takes only 4 seconds to compile changes in the game using Visual Studio 2022 Community Edition, and I can even speed that up using game logic libraries and loading parameters from a file.

I need first person character for Ultra Engine. But I don't know how to do it.
