Drawing using controlpoints

There is an old trick which comes down to drawing a fluid line through controlpoints, by using the average of the controlpoints as anchors.

Here is my quick and dirty go at it:

arguments.callee._name in ActionScript 2

A question on the flashcoders list about an hour ago triggered me to put together a very simple example that I have been wanting to put together for ages now.

How do you get the name of a function?

With function we could refer to:

  • any function
  • a calling function
  • a function being called

My reflection package is at the core of my xflas2 logger. It provides much the same information MTASC can put into a trace statement WITHOUT MTASC (except for the linenumbers).

Anyway, the reflection package is perfectly capable of being used standalone without a logger of some kind. It provides two simple classes with an even simpler API: ClassFinder and FunctionFinder.

Imagine a function:

	
	private static function runExample3() {
		_print (
			"I am :"+
			FunctionFinder.getFunctionName(arguments.callee)+
			" and I am defined in "+
			ClassFinder.getClassName(
				FunctionFinder.getFunctionClass(arguments.callee)
			)+
			" and was called by "+
			FunctionFinder.getFunctionName(arguments.caller)				
		);
	}

Note that it’s static, but it doesn’t have to be, I’m just being a lazy git.

This prints:


I am :runExample3 and I am defined in SampleClass and I was called by main

Now, for the small print : you HAVE to call ClassFinder.registerAll() once somewhere at the start of your program.
