I’m not sure if you’ve noticed this, probably not, but function pointers in AS3 run much, much slower than calling the function directly.
It’s a recent finding, and an annoying one. I use function pointers a lot.
An obvious example would be to easily change the behaviour of a certain object.
Say I have a class that controls movement, it has a class level function variable called UPDATE (ie public var UPDATE:Function), and 3 or 4 actual functions it can point to.
This always me to quickly/easily change the behaviour of an object. Say for example I want an object to run on different movement code once it’s collided with something, I can just do UPDATE = movement2; etc.
However, a pointer for a function runs about 15 times slower than running the function directly, therefore I need a replacement.
And I really have no idea why there is this absurd disparity in speed between the 2. With some variables, accessing a reference is faster than accessing the variable directly, obviously not with functions.
What would you advise as a nice, simple replacement solution for the above example?
