I want to create my own systems for flash (like a scoreboard and made a feedback system) but I honestly have no clue where to even begin when it comes to implementing such things using AS3.
I know how to create say a scoreboard using PHP but then I have no clue at ALL how I would get that into my game using AS3.
Any help/tutorials would be great, Thanks!
You can use the HTTPService component with an Adobe Flex program (the language is based on ActionScript3 and is a mix of MXML for the User Interface and ActionScript3), and receive a response from your PHP script in a specific format (i.e.: XML, plain String, etc), which you can process with AS3 and use to update your Flash application. I mentioned XML because AS3 supports the e4x format for HTTPService, and it becomes really easy to manipulate XML data with AS3.
The Adobe Flex Developer QuickStart has everything you need to get started with Adobe Flex (I went through that route), and there are countless other tutorials online (a Google search for a specific tutorial subject would turn up some results). Another resource worth checking out is the Flex section on Switchonthecode.
An article geared towards what you want can be found on the Loading External data with HTTPService page of the QuickStart guide mentioned above.
Additionally, the Flex Getting Started tutorial articles on Adobe’s wiki platform may be of use, as they offer a lot of examples of the language’s useful features. An article from the wiki on External Interfaces actually explains how to make your Flex Application talk to a JavaScript on the HTML page, which might be useful for you also.
Hope this helps,
