Yes, you can use the Steam API in Ultra with Lua, with it you can send and receive any data between players or server: https://www.ultraengine.com/learn/Steamworks_CreateLobby?lang=lua

#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 * displays[0]->scale, 720 * displays[0]->scale, displays[0], WINDOW_CENTER | WINDOW_TITLEBAR); // Create a framebuffer auto framebuffer = CreateFramebuffer(window); // Create a world auto world = CreateWorld(); // Let there be light and a ship auto camera = CreateCamera(world); camera->Move(0, 20, -20); camera->Turn(30, 0, 0); auto ship = CreateBoxBrush(world, 10, 10, 10); auto light = CreatePointLight(world, 100); light->Move(0, 20, 0); // Slice the dice Plane plane = Plane(0,0,1,0); auto A = CreateBrush(world); auto B = CreateBrush(world); // comment the next line out if you don't want a crash ship->Move(0, 0, 50); // cash me ousside howbow dah ship->Slice(plane, A, B); ship = B->Copy(world, false, false)->As<Brush>(); // Move the sliced result right ship->Move(20, 0, 0); // Main loop while (!window->Closed() and !window->KeyDown(KEY_ESCAPE)) { world->Update(); world->Render(framebuffer); } return 0; }

I'm not a cylinder!

Ok, problem fixed, but I still wonder why this worked with CopyTo: Factory::Factory(A<World> world) { //world = world; // works only with CopyTo this->world = world; // works } Anyway, case closed.

I made an example and now it works. Something wrong in my Factory class must be. #include "UltraEngine.h" #include "ComponentSystem.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 * displays[0]->scale, 720 * displays[0]->scale, displays[0], WINDOW_CENTER | WINDOW_TITLEBAR); // Create a framebuffer auto framebuffer = CreateFramebuffer(window); // Create a world auto world = CreateWorld(); // Let there be light and a ship auto camera = CreateCamera(world); camera->Move(0, 20, -20); camera->Turn(30, 0, 0); auto ship = CreateBoxBrush(world, 10, 10, 10); auto light = CreatePointLight(world, 100); light->Move(0, 20, 0); // Slice the dice auto pivot = CreatePivot(world); pivot->Turn(0, -60, 45); Vec3 normal = pivot->rotation.Normalize(); Plane plane = Plane(normal.x, normal.y, normal.z, 4); auto A = CreateBrush(world); auto B = CreateBrush(world); ship->Slice(plane, A, B); //B->CopyTo(ship, 0); // Works beautifully! ship = B->Copy(world,false,false)->As<Brush>(); // Let's slice again like we did last summer pivot = CreatePivot(world); pivot->Turn(-60, -60, -45); normal = pivot->rotation.Normalize(); plane = Plane(normal.x, normal.y, normal.z, 4); A = CreateBrush(world); B = CreateBrush(world); ship->Slice(plane, A, B); //B->CopyTo(ship, 0); ship = B->Copy(world,false,false)->As<Brush>(); // Now this works too, hmm back to the drawingboard // Move the sliced result right ship->Move(20, 0, 0); // Main loop while (window->Closed() == false and window->KeyDown(KEY_ESCAPE) == false) { world->Update(); world->Render(framebuffer); } return 0; }

#include "PreComp.h" #include "Factory.h" Factory::Factory(A<World> world) { world = world; ship = CreateBoxBrush(world, 10, 10, 10); ship->Move(0, 0, 0); } void Factory::Cut(double x, double y, double z) { auto pivot = CreatePivot(world); pivot->Turn(x,y,z); Vec3 normal = pivot->rotation.Normalize(); Plane plane = Plane(normal.x, normal.y, normal.z, 4); A<Brush> A, B; A = CreateBrush(world); B = CreateBrush(world); ship->Slice(plane, A, B); B->CopyTo(ship, 0); //ship = B->Copy(world,false,false)->As<Brush>(); } Then in Application.cpp (main.cpp): Factory factory(world); factory.Cut(0, -60, -45); factory.Cut(-60, -60, -45); ship = factory.ship;

The ship vanishes.

But this doesn't work: //B->CopyTo(ship, 0); // works ship = B->Copy(world,false,false)->As<Brush>(); // doesn't work

This fixed it, thanks! B->CopyTo(ship, 0);

I tried B->CopyTo(ship, 0); and it works, but since the documentation is missing, I have no idea what the 0 does.

ship = CreateBoxBrush(world, 10, 10, 10); ship->Move(0, 0, 0); auto pivot = CreatePivot(world); pivot->Turn(0, -60, -45); Vec3 normal = pivot->rotation.Normalize(); Plane plane = Plane(normal.x, normal.y, normal.z, 4); auto A = CreateBrush(world); auto B = CreateBrush(world); ship->Slice(plane, A, B); ship = B; pivot->Turn(0, 1, 0); normal = pivot->rotation.Normalize(); plane = Plane(normal.x, normal.y, normal.z, 4); ship->Slice(plane, A, B); // Crash: Assert failed.

Undo redo is indeed a paradox

auto ball = CreateSphere(world); ball->SetMass(1); ball->SetGravityMode(false); auto ballo = ball->Instantiate(world); ballo->SetGravityMode(false); // workaround: this should inherit from ball like SetMass(1) does.

7z has 7 different algorithms, hence the name 7z. The most powerful compression is LZMA2 Ultra.
