Number States

>+>1 : increases by 1 >+>2 : increase by 2 >->2 : decrease by 2 >*>2 : double

State Check

typeof resultstring !== 'string'

then it's an object

for 'exits' must have direction { 'onPass': 'outside', 'onFail': 'Door is closed', 'req': { 'rtavern:doorOpen': true } }

eg puzzlebox { 'onPass': '>>T>openpuzzlebox', 'onFail': 'cannot open puzzlebox yet', 'req': { 'puzzle:openedSectionOne': true, 'puzzle:openedSectionTwo': false, } }

Numerical

{ 'onPass': 'outside', 'onFail': 'Door is closed', 'req': { 'ibox:val:>=': 5 } }

Future Problems

• containers
• trigger multistate edit
• obvious required item in inventory; key->lock,
• NPC
• travel to specific room (across rooms?)
• movement through specific exit fires trigger only first time

Limitations

• Item max three word description?
