Where can I find a tutorial for "Using GPS Location?" It's listed on the tutorials page but is blacked out so I can't click on it.

Is there a way to run a < play> command after an alert box has been dismissed?

thillsman 12 lat temu • zaktualizowano 12 lat temu • 2
I'm working on a Tic Tac Toe app where an alert box tells who wins after a winning play has been made. I would like the alert box to pop up after the winning play (it does currently) and then clear the Xs and Os off the game board when a user dismisses the prompt. Here's what I have:

< if lhs="[var:cur1]" operator="e" rhs="[var:cur2]">
< if lhs="[var:cur1]" operator="e" rhs="[var:cur3]">
< alert title="You win!" message="[var:cur1] is the winner!" />
< play action="resetit" />
< /if>
< /if>

The "resetit" action runs concurrently with the alert. I've tried putting < sync> around the alert and play actions, but it works exactly the same. I know you can delay the sync, but delaying it for a set amount of time wouldn't be a very good user experience. Any tips?

Is there a good way to combine < if> operations with AND or OR?

thillsman 12 lat temu • zaktualizowano 12 lat temu • 2
I'm working on a Tic Tac Toe app. It's functional, but the code's long. To determine whether the game has been won, I use < if> tags to compare variables like this:

< if lhs="[var:cur1]" operator="e" rhs="[var:cur2]">
< if lhs="[var:cur1]" operator="e" rhs="[var:cur3]">
< alert title="You win!" message="[var:cur1] is the winner!" />
< /if>
< /if>

where the variable are the status of the top three boxes on the tic tac toe board (X or O). Is there a cleaner way to say "if cur1, cur2, and cur 3 are equal, prompt alert"?

Thanks!

PS: Is there a good way to share script on the forums?

Local XML file and datasources - error

sstava 12 lat temu • Ostatnio zmodyfikowane przez icahill (Administrator) 12 lat temu • 1
I am trying to do something simple...so I thought. In reality, I may be simple and that could be the problem :) so any help would be greatly appreciated!

My goal was to have a local XML file and display the contents in my app. I was basing the code off of the rssfeed example in the intro to data sources tutorial. The rssfeed app works fine for me...Yay!

So, back to my original goal...displaying the content of an app-local XML file.
When I use a data source to load the XML file, I get a data source error. That is obviously what prevents me from showing the data, but I can't figure out what is causing the error or what the specific error is.

I have copied an rss feed's XML content into my local xml file to make sure the XML file is valid. In my example app, I have two data sources.

One is the Internet-based rss feed...it works.

The other is the same rss content, but copied into an app-local XML file...it fails.

My example app: 





<wire>


   <datasources>


      <datasource name="economistrss" source="http://www.economist.com/rss/the_world_this_week_rss.xml" providertype="xml" query="//item" />     


      <datasource name="economistxml" source="economist.xml" providertype="xml" query="//item" />

      </panel>

      </action>  


       <action name="show-xml" >                       


         <assign property="object:INFO.text" value="[datasource:economistxml.dataSourceResultCount]" />

Question on datasource webinar

steve 12 lat temu • Ostatnio zmodyfikowane przez icahill (Administrator) 12 lat temu • 3
I was watching the datasource webinar and have a couple of questions on how I need to change the queries in order to reflect a slightly different feed structure.

In the webinar, the global post image nodes are structured like this http://imageurl.jpg. However, the feed that I'm working has a url= in front of the image url and it looks more like this . My question is how to alter the query. Does it need to look more like the image query in the "intro to datasources tutorial"

Also, in my feed some of the posts have several images. The are all tagged like
image title. Is there a way to call these images using some sort index parameter the way you can call feed items?

Please let me know if these questions are unclear.

Application Loader - Icon-Small-50.png doesnt meet the size requirements 72x72

mgruberdesign 12 lat temu • Ostatnio zmodyfikowane przez icahill (Administrator) 12 lat temu • 4
I have published the app and downloaded the .ipa file. When I go to send it to apple via the Application Loader, I get an error message:

"iPad: Icon-Small-50.png: icon dimensions (50x50) don't meet the size requirements. The icon file must be 72x72 pixels, in .png format"

The issue I am having is that not all of the icon previews are showing up under the settings screen before I publish. I checked, and my files are all set to the proper dimensions.

Make 'play' have the option to be synchronous.

storycode 12 lat temu • Ostatnio zmodyfikowane przez icahill (Administrator) 12 lat temu • 5
Calling 'play' causes the called action to execute asynchronously - i.e. the action that contains the play will carry on executing without waiting for the called action to complete.
This is a problem if you are creating a series of objects in a loop in response to a user action. You have no way of knowing when the loop completes.
So if the user action causes the current series of objects to be deleted and new ones created, and it is not possible to tell when the action has completed creating the new objects, the user could trigger the action again before it has completed - causing the objects to be deleted before they have finished being created - which causes the app to crash...

It would be really nice if the 'play' action had a flag to make it synchronous so that it could be used as a way of calling actions in the same way that developer created functions are used in any other language - i.e. reusable chunks of code which may change some global variable or passed in parameter and the calling function/action could then act on the modified variables.

Timed Actions

dbdesign 12 lat temu • Ostatnio zmodyfikowane przez ajones 12 lat temu • 6
I am trying to make an animation to play at the launch of the app. I have two images (launchiphone-00000.png and launchiphone-00001.png) that I want to play using an "imagestrip." I have the "imagestrip" and the "playstrip" in place. I want the action to play the animation for 5 seconds.

So I have two problems:
1. My imagestrip images are not showing.
2. How do I make the action run for 5sec before fading to alpha="0"?


<panel name="launchcontainer" alias="LAUNCHCONTAINER" height="100%" width="100%" xpos="0" ypos="0" background="#a58d3c" alpha="1">
<platform device="iPhone"><imagestrip name="launchgraphic" alias="LAUNCHGRAPHIC" prefix="images/launchiphone-" fps="25"></imagestrip></platform>
<platform device="iPad"><imagestrip name="launchgraphic" alias="LAUNCHGRAPHIC" prefix="images/launchipad-" fps="25"></imagestrip></platform>
</panel>

<action name="launchgraphic" oninit="yes">
<playstrip target="LAUNCHGRAPHIC" loops="yes" time="5"/>
</action>

While image strip is a method provided within iOS to allow for burst of animated content, the conversion within iOS from image to sequenced video can be a little cumbersome and does not carry the best performance effort within iOS.

One trick I like to use within Wire when I need to animatie a sequence of images is a combination of load, conditional statements and an action that loops over itself to give me optimal control of my sequence.

First the finish action blocks of code we'll be using:



<main>
<image name="AnimatedSeq" alias="ANIMATED-SEQ" />
</main>

<action oninit="yes">
<assign property="var:frameCount" value="0" />
</action>

<action name="loop">
<if lhs="[var:frameCount]" operator="lte" rhs="26">
<sync delay="0">
<load source="graphics/mySeq[var:frameCount].jpg" target="ANIMATED-SEQ"/>
<assign property="var:frameCount" value="[eval: [var:frameCount] + 1]" />
<if lhs="[var:frameCount]" operator="lt" rhs="26">
<play action="loop"/>
</if>
<if lhs="[var:frameCount]" operator="=" rhs="26">
<alert message="I'm Done" />
</if>
</sync>
</if>
</action>


First let's look at the image we will be replacing in the sequence.


<image name="AnimatedSeq" alias="ANIMATED-SEQ" />


Nothing fancy here, we simply just place the first image in the sequence that we want the user to see.

Next we want to create a var that we can use to track the sequence and to use in showing the appropriate image. So we have a simple oninit action that sets the var:frameCount to 0 upon loading the app.

<assign property="var:frameCount" value="0" />

This var shows that we want to make sure that our images are sequenced and named appropriately. So instead of the image strip requirement of a prefix and 4 digit number, we can simplify this. We CAN optionally add a prefix, but it's not required, here I used 'mySeq' then just start you numbering at 0.

mySeq0.jpg, mySeq1.jpg mySeq2.jpg, mySeq3.jpg, etc...

In my example above you will see the number '26' in a few places, this is the total images my sequence requires.

Let's take a look at the action 'loop'.

I have a conditional statement that leads off the action and checks the var:frameCount value.

<if lhs="[var:frameCount]" operator="lte" rhs="26">

This will make sure that once we kick off this action to animate our sequence that we are within the bounds of our sequence numbering and then using that var: perform a load action on the source of the image.

<load source="graphics/mySeq[var:frameCount].jpg" target="ANIMATED-SEQ"/>

Here, since we are starting the animation we will see mySeq0.jpg first be placed in the load. Then immediately following the load (remember we are in a sync) we increment the var:frameCount with an eval: statement:

<assign property="var:frameCount" value="[eval: [var:frameCount] + 1]" />

Now we will create two sibling conditional statement to fork the action and decide if we are done with the animation or need to loop the action over itself and continue incrementing the sequence until we hit 26.

<if lhs="[var:frameCount]" operator="lt" rhs="26">

The first conditional checks to see if our var:frameCount is less than our last slide, 26. If so, we ask the action to start again. And in doing so the action will now go and load slide mySeq1.jpg and increment the var:frameCount to 2 and continue this pattern until it hits our other conditional statement:

<if lhs="[var:frameCount]" operator="=" rhs="26">

Once the var:frameCount hits our ceiling in the sequence, I have placed an alert to just verify the sequence has completed.

While this may initial seem like a complex solution to a control iOS provides, the control and sequencing makes the implementation very repeatable and reliable without losing performance on the device. This also gives a very nice introduction into the power of looped actions and conditional statements.

Please let me know if you have any questions.
