Hi,

I've completed this tutorial - http://www.republicofcode.com/tutorials/flash/portfolio_bc/[^] but when I view the project on HTML the images don't stop and wait for you to hover over the thumbs, they play repeatedly for about 0.2 of a second each on loop! What am I doing wrong?

In the code the first step is;

C#

btn1_btn.onRollOver= function(){
myScreen_mc.gotoAndStop(1);
};

What is the significance of (1) - what does this relate to?

Thanks,
Alex

Documentation on this API says it's a frame; must be a frame number.

Simple answer: Stop wasting your time with Flash. The world is abandoning it and any developer with any foresight will jump that ship right now - let alone teach yourself it! Adobe are gradually discontinuing Flash an shifting to HTML5/CSS3 - already Flash doesn't work on newer Android phones e.g. Galaxy S3 (basically, Jelly Bean).

I would suggest you start learning HTML5/CSS3 - the new(ish) standard though it's been around for a while now and is supported in all major browsers & IE9 (some bis are in IE8). Start here: http://www.w3schools.com/html/html5_intro.asp

When you come to wanting to do slide shows, you have 2 options. Either go all out HTML5/CSS3 (and lose some browser support) by using CSS3 animations or go the JavaScript route in which case you're best to look at jQuery - by far the best/easiest. You can set up a slideshow less than 3 lines of code once you've learnt a little!

I realise this might be a bit of a learning curve with more to it before you reach doing slide shows, but it is certainly worth it! Especially if you are only just beginning with Flash (as it appears you are). No point teaching yourself an already outdated technology :)

Hope this helps,
Ed

Thank you so much for your response. At the oment I'm desperately working to finish a portfolio link so I can apply for a job. At this point in time I don't have the time to teach myself HTML5 but I will certainly be sure to rebuild in HTML5 in the future. In the meantime is there any advice you can give me on how to quick fix the error above?

Thanks,
Alex

May seem a bit dumb, but you do have the initial stop(); call at the start of your ActionScript, right? If not, your flash show would play each frame at standard frame rate (which I think is 0.2 frames per second ish) - it would explain why it isn't working properly. Please see this quote from the article you linked to:
"We will now stop the movie from playing these frames without us telling it to do so, click on the very first frame in the layer named Actions and then press F9 to open up the ActionScript panel (or go to Window>Actions). Simply type Stop(); to stop the movie from playing those frames automatically." and refer back to the article screenshot provided too.

Hope this helps - it's the only thing I can think of that could be wrong!

Thanks Ed, I'll try this tonight. Do I only have to do this once at the beginning as instructed? Or before each goandstop command? Apologies, I'm a complete beginner!

Thanks,
Alex

You should only have to do it once at the very start since "goandstop" will go to the specified frame and then call stop for you. Stopping before the "goandstop" command would make no noticeable difference since goandstop would change the frame immediately afterwards.

Just in case, here's some possibly helpful info:
Flash files are animations (or movies) and, just like any movie, they have frames. Just like you'd expect from a film, it's default aim is to play the frames at a set frame rate and produce an animation. So when you open a Flash file, by default, it just starts playing. However, you are trying to produce a mini application in which the movie only "plays" (i.e. goes to the frame you want) when the user generates some input (i.e. clicks/hovers over a button). Since you want the first frame to be displayed and then the movie to stop, your code must override the default playing state by calling "stop()" at the very start of the movie. Thus the first frame is shown. Then, when a user hovers on a thumbnail, you call goandstop, which plays the movie from the current frame, straight into the specified frame (ignoring any inbetween). It then calls stop to prevent the movie playing any subsequent frames. Thus you get the affect of going to a particular image :) It is helpful to always think of Flash files as movies but with events and code that can change how the movie behaves.

Hope this helps,
Ed
