Animated Model Example — Urho3d Code
Animates a model using an animation controller.
#include <Urho3D/Engine/Application.h>
#include <Urho3D/Scene/Scene.h>
#include <Urho3D/Graphics/AnimatedModel.h>
#include <Urho3D/Animation/AnimationController.h>
using namespace Urho3D;
class AnimatedApp : public Application {
public:
AnimatedApp(Context* context) : Application(context) {}
void Setup() override {}
void Start() override {
scene_ = new Scene(context_);
Node* node = scene_->CreateChild("Robot");
AnimatedModel* model = node->CreateComponent<AnimatedModel>();
model->SetModel(GetSubsystem<ResourceCache>()->GetModel("Models/Jack.mdl"));
node->CreateComponent<AnimationController>()->PlayExclusive("Models/Jack_Walk.ani",0,true);

URHO3D_DEFINE_APPLICATION_MAIN(AnimatedApp)Urho3d Language Guide
Urho3D is an open-source, cross-platform 2D and 3D game engine written in C++ with optional AngelScript and Lua scripting. It provides a lightweight, flexible environment for building games and real-time simulations.
Primary Use Cases
- ▸2D and 3D PC games
- ▸Mobile games (Android/iOS)
- ▸Educational simulations
- ▸Real-time visualizations
- ▸Interactive prototypes
Notable Features
- ▸C++ core with scripting via AngelScript/Lua
- ▸Cross-platform (Windows, macOS, Linux, iOS, Android)
- ▸Scene graph and node-based architecture
- ▸Integrated physics (Bullet Physics) and networking
- ▸Flexible rendering pipeline (shaders, lights, shadows)
Origin & Creator
Urho3D was created in 2007 by the Finnish developer Jukka Jylänki, later developed and maintained by a community of contributors.
Industrial Note
Urho3D is valued by developers seeking a lightweight, open-source engine with full access to C++ code, cross-platform deployment, and integrated physics and rendering systems.
