Flash MX 2004 Games Summary Flash Communication Server is a robust way to add multi-user connectivity to your game. It is simple to use and easy to set up. The communication is handled using a server-side shared object that all connections can write to and read. Using this simple technique most of the multiuser problems that you are likely to face as a game developer can be handled without having to write any server-side code. If you do need to write server-side code then you can leverage your ActionScript knowledge. 374
24 Embedding Flash In this chapter we look at how programmers using other languages can add Flash to their executable programs. By creating a specialized wrapper we can get all the dynamic animation facilities that Flash can provide together with the excellent development environment and we can extend it to use operating system features such as the file system and purpose-made non-rectangular skins. Flash operates as an ActiveX control in the Windows environment and as such is fairly easily embedded into Visual Basic, C# and C++ executables. We also look at communication between the parent program and Flash. Embedding Flash into a Visual Basic program On the CD you can find ‘Examples/Chapter24/VB/vbflash.vbp’, a Visual Basic 6 project file. Using this you can examine how the code works. Alternatively, if starting from scratch, follow these simple steps. 1 Run your copy of Visual Basic and start a new Standard Exe. 2 Choose ‘Project/Components...’ from the main menu and select ‘Shockwave Flash’ from the list box. 3 Click on the new icon added to the Tools palette and drag a window on the form. 4 To add an ‘swf’ to this, place the following code in your Form_Load event: flash.Movie = App.Path & "\yourmovie.swf" It’s as simple as that. In the sample project we take it a stage further by communicating between the Flash and the VB wrapper. Setting variables in the Flash movie To set variables in the Flash movie use the following syntax: Flash1.SetVariable "variablename", "content" Setting the frame for the Flash movie To set the frame for the Flash movie use the following syntax: Flash1.GotoFrame frameNum 375
