Update a running tween

[gareth]

I am trying to increase the height of a jump performed by my character depending on how long the space bar is held down. 

 

I have a working demo here: 

 

What I don't understand how to do is to update the end point (and speed) of the tween once it is running. At the moment I have a double jump effect, but ideally I would like the height of the jump to increase with the length of the press.

Non-detailed answer before I head to work: I think you are looking for .updateTo

thanks Maelfyn - I gave a go:

I guess it does not work, because the y value use the css plugin?

ok wrapping the "y" in css tags solved the above problem

 

e.g 

   jump.updateTo({css:{y:-jumpAmount}},true)

not sure if this is the best way to do it, but it seems to be working ok now:

I'll work on this a bit. Maybe my solution will help.

Here's my version. This may or may not work for your circumstances. I didn't opt to use a Timeline. Instead I just repeatedly call the same function, adjusting the jumping Tween, while the spacebar is held.

 

There are probably a million valid ways to code this, but here's the version I threw together. Note that this would only work for completely flat surfaces since it Tweens y to 0 every time. Additional logic would have to be added to compensate for that.

thank you very much Maelfyn, very interesting.  Your version seems to respond a little better to the key press.
