# 오브젝트 npcProperty

npcProperty는`Map.putObjectWithKey(x, y, dynamicResource, option)`함수의

option 파라미터에서 지정할 수 있으며, 다음 7가지 속성을 지정할 수 있습니다.

<table><thead><tr><th width="171.33333333333331">이름</th><th width="113">타입</th><th>설명</th></tr></thead><tbody><tr><td>name</td><td>string</td><td>오브젝트 위에 표시될 이름</td></tr><tr><td>hp</td><td>number</td><td>오브젝트의 현재 체력</td></tr><tr><td>hpMax</td><td>number</td><td>오브젝트의 최대 체력</td></tr><tr><td>gaugeWidth</td><td>number</td><td><p>체력 게이지바의 너비</p><p>생략시 이미지의 너비 크기로 설정됩니다.</p></td></tr><tr><td>hpColor</td><td>number</td><td>체력 게이지바의 색상<br> ex) 0x03ff03 (초록색)</td></tr></tbody></table>
