Request: Variable Tweening

[Tigairius]

This is something I think could really improve some things on Graal. Most likely one of the most useful things that could be added to GScript2: tweening.

Right now Stefan has added createAnimation() to v6, but I really think it would be much more effective to add tweening instead.

Example of how it would work.

PHP Code:

//#CLIENTSIDE
function onCreated() {
  with (findimg(200)) {
    this.image = "door.png";
    this.layer = 3;
    this.x = 30;
    this.y = 30;
    this.tween("alpha", 0.5, 0, 1);
  }
} 


The door would fade in, taking alpha from 0 to 1 in 0.5 seconds.

More interesting things like player tweening could be usable too.

PHP Code:

//#CLIENTSIDE
function onCreated() {
  player.tween("x", 10, player.x, player.x + 10);
} 


This could move the player to the right by 10 tiles over 10 seconds.

Tweening should also be usable on GuiControl objects, for tweening a window's alpha or other variables.


Thoughts, ideas? Any more to add?
I would really like to see this added in v6. It is similar to createAnimation() but much more powerful and flexible.
