Não é um APK nem um projeto/cena completo importável por um único clique. Não contém fontes da engine. 1. Coloque Images/heart-full.png e Images/heart-empty.png na pasta Images do seu projeto. 2. Coloque UI/hud.aeui na pasta UI. Na área Interface, informe UI/hud.aeui e use Abrir; depois Salvar para registrá-lo como recurso do projeto. 3. Adicione os três arquivos .cs à área de código e compile o projeto. 4. No objeto Jogador, anexe PlayerHealth. No objeto HUD, anexe Canvas UI e HeartHud. 5. Atribua o recurso UI/hud.aeui no Canvas UI e use Apresentação = Tela. 6. Atribua Jogador no campo Player do HeartHud. Salve a cena e a UI. 7. Entre em Play. Dano/Cura mudam a vida e os corações; Interagir não executa o C#. 8. HeartDamageTrigger é opcional: anexado a uma zona de sensor 3D, retira vida na entrada. Exige participação física 3D do jogador e PlayerHealth no objeto resolvido pelo evento. Vida começa em 3, limita dano/cura a 0–3 e reinicia ao reabrir Play. Não implementa respawn, invulnerabilidade, meio coração ou save persistente. O .aeui foi produzido pelo serializer nativo e relido com 10 elementos válidos. Compilação dos scripts é registrada separadamente no manifesto de exemplos. Esta edição de documentação não executou o cenário em aparelho físico. As imagens e os scripts foram autorados para este tutorial. A política de redistribuição acompanha a política editorial do portal; uma licença pública não foi definida. O pacote não concede licença dos fontes da engine.
