[actionstep-core] Rotation

[thomas m. <tho...@gm...>]

Hello all,

i'm having trouble rotating views ... is there anything I should be aware of
?

using rotateByAngle(90) results in my view disappearing alltogether

trying to use mcBoundsHolder._rotation does the same

hope i'l just mising something :)

This used to work. I'll have a look.

actually I think I was lookng for setFrameRotation and it works :)

Re: [actionstep-core] Rotation

[thomas m. <tho...@gm...>]

by the way is there a method (im not that good with maths ...) to shift the
rotation center ? I know there probably is out there but already  built in
actionstep ?

Re: [actionstep-core] Rotation

[Ray C. <rc...@gm...>]

Hi,
maybe you can attach it to another clip.

Say you have a box w by h, which is originally at (x,y). You want the
centre of rotation to be at (xc,yc). So, attach it to a clip:

daddy_mc.createEmptyMovieClip("kid_mc", daddy_mc.getNextHigestDepth());
daddy_mc._x = x-xc;
daddy_mc._y = y-yc;
kid_mc._x = xc;
kid_mc._y = xc;

Since the absolute coordinates of the attached clip takes into account
the coordinates of the parent clip, kid clip appears at the point (x,
y) but has rotation centre (xc, yc).

To do this in ActionStep your movieclip heirarchy should look like this:

mcBounds
|- holder
|- daddy_mc
|- kid_mc

Re: [actionstep-core] Rotation

[thomas m. <tho...@gm...>]

the good old method

I thought about somethin more complex where the new center was computed but
this is way better :)

thanks

Re: [actionstep-core] Rotation

[thomas m. <tho...@gm...>]

I was thinking it should be possible to set a center point and compute the
new x and y based on the rotation angle, new x, new y , old x, old y

without having to resort to a container clip

like if you rotate a square by 90=B0 and want its rotation point to be its
center you rotate it and then have to add half its width to its x position
you then get the desired behaviour

I thought there was a formula to have it work with any angle and any
rotation point

I'll keep on looking for this but if someone knows what I mean and have it
handy ... :)

maybe its basic stuff but trigonometry and I have to schedule a meeting

should have been : you have to add its whole width

[actionstep-core] MVC

[Ewan M. <mr...@mr...>]

Hello,

I'm trying to program my application using MVC pattern as described  
in Cocoa Fundamentals.

"The delegate object itself is typically, but not necessarily, an  
object, often a custom object,
that controls some part of the application (that is, a coordinating  
controller object)."
CocoaFundamentals p148.

Great so my thoughts so far I can either initialize my view objects  
with their controller e.g.
var myView = (new MyView).initWithController((new MyController).init());
or as the text above suggests I can set it as a delegate and  
implement an informal protocol between the controller and view e.g.
var myView = (new MyView()).init();
myView.setDelegate((new MyController).init));

 From the actionstep source code there are three different ways to  
implement setDelegate in your Delegator

It can be notified (see ASFieldEditor.as)
It can be called directly and the delegate check to see that it  
conforms to informal protocol(see ASTreeView.as)
It can be called directly but not checked to see if it responds to  
calls (see NSImage.as , when is m_delegate used?)

You can create an interface if you want (ASFieldEditingProtocol.as)
The naming strategy is either append Protocol or Delegate.

Does this sound about right?

So say I've got 10 small simple views shall I just bundle all my  
control code in one or two Controllers and set either as delegate for  
all the view?
There doesn't seem much point spreading all the control code around  
by having parallel Views and Controllers. (i.e. one controller for  
each view).

Cheers,

Yes, it does.

Yeah, you can absolutely do something like this. In fact, you may
notice that the first argument for most delegate methods is the
"sender", which is the object that is requesting the delegated
behaviour. Just do equality testing on that and have it behave
appropriately.

Great, thanks for the reassurance and advice, Ewan.
