Released demo: https://dreikblack.itch.io/slipgate-tactics Changed a name to Slipgate Tactics, because Quake publisher does not like when its brands used in fan projects until its mods

Same error when load in my project demo map (by new game btn) or Polygon map. In release mode issue not happens.

With latest updates app crashes when i'm building a brush. Had no problem with exactly method from my example before, but this example from Learn still works tho https://www.ultraengine.com/learn/CreateBrush?lang=cpp #include "UltraEngine.h" using namespace UltraEngine; shared_ptr<Brush> createConeBrush(shared_ptr<World> world, float initWidth, float width, float length, float height, float minHeightArg) { auto brush = CreateBrush(world); float minHeight = minHeightArg != 0 ? minHeightArg * 0.5f : Max(2 * 0.4f, -height * 0.1f); brush->AddVertex(-initWidth * 0.5f, -minHeight, 0); //SW l brush->AddVertex(-width * 0.5, -height * 0.5, length);//NW brush->AddVertex(width * 0.5, -height * 0.5, length);//NE brush->AddVertex(-width * 0.5, height * 0.5, length);//NW h brush->AddVertex(width * 0.5, height * 0.5, length);//NE h brush->AddVertex(-initWidth * 0.5f, minHeight, 0); //SW h 5 brush->AddVertex(initWidth * 0.5f, minHeight, 0); //SE h 6 brush->AddVertex(initWidth * 0.5f, -minHeight, 0); //SE 7 //back auto face = brush->AddFace(); face->AddIndice(0);//SW face->AddIndice(5);//NW face->AddIndice(7);//NE face = brush->AddFace(); face->AddIndice(5);//SW face->AddIndice(6);//NW face->AddIndice(7);//NE //bottom face = brush->AddFace(); face->AddIndice(0);//SW face->AddIndice(1);//NW face->AddIndice(2);//NE face = brush->AddFace(); face->AddIndice(2);//SW face->AddIndice(7);//NW face->AddIndice(0);//NE //top face = brush->AddFace(); face->AddIndice(6);//SW h face->AddIndice(4);//NW h face->AddIndice(3);//NE h face->AddIndice(5);//SE h face = brush->AddFace();//left face->AddIndice(3); face->AddIndice(1); face->AddIndice(0); face->AddIndice(5); face = brush->AddFace();//"face" face->AddIndice(1); face->AddIndice(2); face->AddIndice(4); face->AddIndice(3); face = brush->AddFace();//right face->AddIndice(2); face->AddIndice(4); face->AddIndice(6); face->AddIndice(7); brush->Build(); brush->SetPickMode(PICK_NONE); brush->SetCollisionType(COLLISION_NONE); brush->SetRenderLayers(0); return brush; } 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_CLIENTCOORDS | 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->SetPosition(0, 1, -2); camera->SetClearColor(0.125f); createConeBrush(world, 1, 2, 2, 1, 0.1 ); //Main loop while (window->Closed() == false and window->KeyDown(KEY_ESCAPE) == false) { world->Update(); world->Render(framebuffer); } return 0; }

It still loading a default mat even though it uses another one

Managed to fix it in the game in Pivot's component Start() method by: auto entity = GetEntity(); if (entity) { entity->SetRotation(entity->GetRotation(true), true); } But resetting rotation does not work for this example O_o

If brush was SetParented to a pivot World::Pick() starts ignoring it. How it should be: How it is: #include "UltraEngine.h" using namespace UltraEngine; bool PickFilter(std::shared_ptr<Entity> entity, std::shared_ptr<Object> extra) { if (entity->GetCollider() == nullptr) { return false; } 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, 2, -3); camera->SetRotation(25, 0, 0); camera->SetDebugPhysicsMode(true); auto light = CreateDirectionalLight(world); light->SetRotation(35, 45, 0); light->SetColor(1); auto floor = CreatePlane(world, 100, 100); floor->Move(0, -1, 0); auto b1 = CreateBox(world, 2.0f); b1->SetPosition(-3.0f, 0.0f, 0.0f); b1->SetColor(1, 0, 0); auto pivotParent = CreatePivot(world);//added a parent here b1->SetParent(pivotParent); auto b2 = CreateBox(world, 2.0f); b2->SetColor(0.0f, 0.0f, 1.0f); b2->SetPosition(3.0f, 0.0f, 2.0f); b2->SetRotation(0.0f, 45.0f, 0.0f); auto pivot = CreatePivot(world); auto rod_scale = 5.0f; auto rod = CreateCylinder(world, 0.05f); rod->SetCollider(nullptr); rod->SetParent(pivot); rod->SetRotation(90.0f, 0.0f, 0.0f); rod->SetPosition(0.0f, 0.0f, rod_scale / 2.0f); rod->SetScale(1.0f, rod_scale, 1.0f); auto sphere = CreateSphere(world, 0.25f); sphere->SetCollider(nullptr); sphere->SetParent(pivot); sphere->SetColor(0, 1, 0); sphere->SetPosition(0.0f, 0.0f, rod_scale); auto spin_speed = 0.5f; while (window->Closed() == false and window->KeyDown(KEY_ESCAPE) == false) { pivot->Turn(0.0f, spin_speed, 0.0f); auto target_pos = Vec3(0.0f, 0.0f, rod_scale); target_pos = TransformPoint(target_pos, Mat4(), pivot->GetMatrix(true).Inverse()); // Perform a ray cast auto pick_info = world->Pick(pivot->GetPosition(true), target_pos, 0.25f, true, PickFilter); if (pick_info.success) { sphere->SetPosition(pick_info.position, true); } else { sphere->SetPosition(target_pos, true); } world->Update(); world->Render(framebuffer); } return 0; }

Still need getters for ParticleEmitter (GetParticleVelocity, GetParticleTurbulence etc.)

If you do "box->SetParent(pivot);" before loop there will be no shadow at all. In this example there is a shadow, but with Space box became child of rotating pivot and shadow is stay still static. #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 framebuffer = CreateFramebuffer(window); auto world = CreateWorld(); //Create a camera auto camera = CreateCamera(world); camera->SetClearColor(0.125); camera->SetFov(70); camera->Move(-1, 2, -6); //Create light auto light = CreatePointLight(world); light->SetPosition(0, 1, 0); light->SetColor(2); //Create ground auto ground = CreateBox(world, 20, 1, 20); ground->SetPosition(0, -0.5, 0); ground->SetColor(0, 0.4f, 0); auto pivot = CreatePivot(world); pivot->SetPosition(0, 0.5, -1); auto box = CreateBox(world, 1, 1, 1); box->SetPosition(0, 0.5, -1); while (window->Closed() == false and window->KeyHit(KEY_ESCAPE) == false) { if (window->KeyHit(KEY_SPACE)) { box->SetParent(pivot); } pivot->Turn(2); world->Update(); world->Render(framebuffer); } return 0; }

It should not prevent it at all. Are you sure there are no other pointers exist to those weapons? Example how same reusing of var deletes prev entity without other references to it: local displays = GetDisplays() local window = CreateWindow("Ultra Engine", 0, 0, 1280, 720, displays[1], WINDOW_CENTER | WINDOW_TITLEBAR) local framebuffer = CreateFramebuffer(window) local world = CreateWorld() -- Create a camera local camera = CreateCamera(world) camera:SetClearColor(0.125) camera:SetFov(70) camera:Move(0, 2, -8) -- Create light local light = CreateBoxLight(world) light:SetRotation(45, 35, 0) light:SetRange(-10, 10) local box = CreateBox(world) box:SetPosition(1, 1, 1) -- Main loop while window:Closed() == false and window:KeyHit(KEY_ESCAPE) == false do collectgarbage() world:Update() world:Render(framebuffer) if (window:KeyHit(KEY_SPACE)) then box = CreateBox(world) end end

But it does exist Docs does not have it tho You can add "hat:Detach()" to test https://www.ultraengine.com/learn/Entity_Attach?lang=lua

Only closing console and stopping debug manually can close an app if fps limit was seted in World::Render() #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 world auto world = CreateWorld(); world->RecordStats(); //Create a framebuffer auto framebuffer = CreateFramebuffer(window); //Create a camera auto camera = CreateCamera(world); camera->SetClearColor(0.125); //Main loop while (window->Closed() == false and window->KeyDown(KEY_ESCAPE) == false) { world->Update(); world->Render(framebuffer, false, 120); } return 0; }

In ParticleEmitter class Instantiate and Copy are private. If i do it via Entitiy's Instantiate i getting ParticleEmitter with default mat and params. Copy() seems to copy a mat, but not params. #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_CLIENTCOORDS | 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->SetPosition(0, 1, -2); camera->SetClearColor(0.125f); //Create a particle emitter with 50 particles auto emitter = CreateParticleEmitter(world, 10); emitter->SetVelocity(0, 0, 0); emitter->SetParticleTurbulence(10000); emitter->SetMaterial(LoadMaterial("/Materials/default.mat")); auto emitter2 = emitter->As<Entity>()->Instantiate(world); emitter2->SetPosition(1, 0, 0); //Main loop while (window->Closed() == false and window->KeyDown(KEY_ESCAPE) == false) { world->Update(); world->Render(framebuffer); } return 0; }

Since tech demo public release some effects were added such as: - fire muzzle effects, particles for shots - particles for explosions - blood particles on hits and gibbing - blood decals on units when they getting damage and on the floor, when they gibbed - few gibs beside a head, with a physics Beginning of demo level can be seen here. Want to release the demo in few weeks.
