View Full Version : SQUIDScript demo (simple xml-based scripting language)

07-30-2006, 10:42 AM
I needed a way to script events (cutscenes, dialogs, etc) in an AS3 game I'm making, so I came up with a basic scripting language using xml. One of the cooler features is that the language is extendable by passing it an api-object, and also that script execution can be paused (for instance, when a dialogbox is opened) and continued again (for instance, when the ok-button is pressed in the dialog box). It also supports conditions (if), loops (while), and variables. I'm working on implementing functions.

Anyway, I attached a simple example. It has a script written in xml in the first frame of the fla, but off course this could be an external file (which is actually how I intend to use it).

I do know it can still be improved (a destroy-method needs to be added etc), but it's working and pretty stable.

Please tell me what you think.

I reworked a large part of the code :

- I now have variable scope (meaning a <then>, <else>, <loop> or <code> block always has it's own scope, with variabkle inheritance from the containing scope)
- It is now possible to pause the script from anywhere - so even a function called in an <if>-statement can pause the script, which is pretty cool
- Functions! That's right, you can now write your own functions in the scripting language, complete with parameters and a return-value - check the example in the zip.

Now, variables and scripted functions will be removed after the script has been executed, so next up is a way to specify global variables and functions.

The zip in the first post has been updated.

Come on people, gimme some feedback! :)

Had to unset my compiler's strict mode setting to get it to compile, but it works! :) Nice... pretty soon you'll write your own Flex (oh yeah... I get it: "Faaaall_x", like saying "flex" with a japanese accent :)).

Can't wait for Fuse to be ported to AS3... (but then, 1.1 is still not officially released for AS2, is it :D)

Yeah, it's made in non-strict mode as that's F9's default mode, I'll see if I can get it to work in strict mode but I'm not sure if it's worth it.
Not sure what Fuse is, could you explain?

Okay, strict mode is now supported.

Fuse (http://www.mosessupposes.com/Fuse/) is a very cool AS tween sequencing kit based on the ZigoEngine. In a way similar to what you did with SQUID, check it out. Unfortunately, its release seems to be delayed... (it's waiting for the docs to be finished, I think :))
