<center><h3><<print UInv.Version()>></h3></center>This is some simple sample code intended to show you how you can use the Universal Inventory System (UInv) functions in your Twine project. It's best if you open this sample code in the Twine editor, and have the story playing on one side of the screen while looking at the source code in the Twine editor on the other side of the screen. That way you can see what the code is doing and read how it does it at the same time. <i class="fa fa-exclamation-circle" /> Before running this from inside the Twine editor you'll want to change the file paths used in your JavaScript and Stylesheet sections to use the correct file path for your computer. See [[here for details]]. If you aren't already, you may want to close this window and run this from the Twine editor using "Test" mode. That would allow you to watch the values change inside the {{{$UInvBags}}} variable as you move through the story passages. See the animation below if you don't know how to use "Test" mode in Twine. <img @src='setup.Path + "images/HowToWatchVariables.gif"' style='color: lawngreen;' alt='(If you are seeing this text instead of an image, please edit the setup.Path variable at the top of the JavaScript section to point to the correct directory.)'> ''Note:'' You should see two error messages pop up when you try to go to the next passage if you have {{{<<run UInv.SetUserAlerts(UInv.ERROR_SHOW_ALERT + UInv.ERROR_SHOW_PASSAGE_NAME)>>}}} in the StoryInit passage (by default that line is commented out). This is done intentionally as an example of how UInv can help you spot and prevent errors in your code. <i class="fa fa-exclamation-circle" /> You can also type "xyzzy" at any time, which will toggle a "debug mode", which determines whether UInv errors will appear in the console window or not. You can hit {{{F12}}} or {{{CTRL+SHIFT+I}}} to open the console window in most browsers. [[Let's begin.]] - or - [[Let's skip ahead to the good stuff.|passage 7][UInv.AddBag("Treasures")]] ''Note:'' You should see two error messages below if you have {{{<<run UInv.SetUserAlerts(UInv.ERROR_THROW_ERROR + UInv.ERROR_SHOW_PASSAGE_NAME)>>}}} in the StoryInit passage (by default that line is commented out).

[[Return to Start|Start]] <<link "Close Window">><<run window.top.close()>><</link>><<run UInv.AddItem("Treasures", "gold coin", 50)>>Here's an example of how you can limit the transfer of items between "bags" by adding an event handler which checks the item's type. You can click anywhere (not including the UI bar on the left or the scrollbars) to cancel the radial menu. Treasures: <div data-uinv="table" class="Treasures-table" id="Treasures" data-rowclass="Treasures-row" data-cellclass="Treasures-cell" data-itemclass="Treasures-item" data-iconclass="Treasures-icon" data-textclass="Treasures-text" data-cellrows="3" data-cellcolumns="5" data-cellmargin="5" data-bordermargin="4"></div> CoinPouch: (only accepts gold coins) <div data-uinv="table" class="Chest-table" id="CoinPouch" data-rowclass="Chest-row" data-cellclass="Chest-cell" data-itemclass="Chest-item" data-iconclass="Chest-icon" data-textclass="Chest-text" data-cellrows="1" data-cellcolumns="3" data-cellmargin="3" data-bordermargin="7"></div> This is done by putting the following code in this passage: {{{ <<run UInv.AddEventHandler("table", "Accept", "acceptTest")>> }}} And having an {{{<<acceptTest>>}}} widget (in a different "widget" tagged passage) like this: {{{ <<widget "acceptTest">> <<set _e = $args[0]>> <<if _e.destBag == "CoinPouch">> <<set _UInvReturn = { acceptVal: !!UInv.ItemHasTag(_e.srcBag, _e.draggedItem, "type", "money") }>> <</if>> <</widget>> }}} [[Reload current passage|passage 9]] <<run UInv.AddEventHandler("table", "Accept", "acceptTest")>> <<widget "acceptTest">> <<set _e = $args[0]>> <<if _e.destBag == "CoinPouch">> <<set _UInvReturn = { acceptVal: !!UInv.ItemHasTag(_e.srcBag, _e.draggedItem, "type", "money") }>> <</if>> <</widget>>
