float x = 0.f;
float y = 0.f;
};
namespace MM {
template <>
void ComponentEditorWidget<Transform>(entt::registry& reg, entt::registry::entity_type e)
{
auto& t = reg.get<Transform>(e);
ImGui::DragFloat("x", &t.x, 0.1f);
ImGui::DragFloat("y", &t.y, 0.1f);
}

void ComponentEditorWidget<Velocity>(entt::registry& reg, entt::registry::entity_type e)
{
auto& v = reg.get<Velocity>(e);
ImGui::DragFloat("x", &v.x, 0.1f);
ImGui::DragFloat("y", &v.y, 0.1f);
}
}
