Simple Counter Example - Urho3d Typing CST Test

Simple Counter Example — Urho3d Code

A minimal Urho3D C++ example demonstrating a counter incremented by keyboard input.

#include <Urho3D/Engine/Application.h>
#include <Urho3D/Input/Input.h>
#include <Urho3D/Engine/Engine.h>
#include <Urho3D/UI/Text.h>

using namespace Urho3D;

class CounterApp : public Application {
public:
	CounterApp(Context* context) : Application(context), count(0) {}

	void Setup() override {}
	void Start() override {
		text = new Text(context_);
		text->SetText("Count: 0");
		text->SetFont(GetSubsystem<ResourceCache>()->GetFont("Fonts/Anonymous Pro.ttf"), 40);
		GetSubsystem<UI>()->GetRoot()->AddChild(text);
	}

	void Stop() override {}
	void Update(float timeStep) {
		Input* input = GetSubsystem<Input>();
		if (input->GetKeyDown(KEY_UP)) count++;
		if (input->GetKeyDown(KEY_DOWN)) count--;
		text->SetText("Count: " + String(count));
	}
private:
	int count;
	SharedPtr<Text> text;
};
