RUBY - XY Surface

[Rocko]

Appreciated...

I had changed the variables to lower case... But still doesn't work.

I noticed that this works:
@sx=getViewSize;


But this doesn't:
@sx=getViewSize[0];

Why can;t I assign @sx to be a single variable out of an array ?

You can assign a single variable from an array, and it is done just as you tried it. If it doesn't work it could mean you previously used the same variable for an array. However, wild guessing won't help you. Prepare a schematic that shows your issue, so that we can have a look. I wouldn't know how else to help.

In your fsm Rocko, there's a redraw in the draw section.
I think it also helps to define the @vw and @vh in the draw section.
For eg: This works fine...

Code: Select all

def isInMousePoint x,y 
true
end
def mouseLDown x,y
    captureMouse
end
def mouseMoveCaptured x,y
    if x > @vw then output 0, x = @vw end
    if x < 0   then output 0, x = 0   end 
    if y > @vh then output 1, y = @vh end
    if y < 0   then output 1, y = 0   end 
    output 0, @x=x
    output 1, @y=y
    redraw
end
def mouseLUp x,y
   releaseMouse
end

def draw v
@vh = v.height-1
@vw = v.width-1
pen = Brush.new @c1,0.2
v. drawEllipse pen,[@x,@y,1,1]

end

Hi,

Your help to offer is really appreciated. Here is my code for your reference.

hmm ... Now I've lost track ... Is there still a problem ???

Seems to work as expected here.

The only thing I suggest ... if the window is re-sized, everything recalculates and places the 'select ball' in field.

Hi,

Notice this line with the '#' mark:
#@sx=getViewSize[0]; //This is the problematic line

If you remove the # to make it active. Then restart the FSM, it doesn't start and reports an error.

Hey Rocko,

this fix should work. It was like I said, you try to access the view before it is initialized. Another tip: always use methods, don't just declare variables somewhere in the RubyEdit. The right place for this is a method called init. In this case a variation is used: Instead of initializing the vars at init of the RubyEdit, I use an afterload trigger to run another method (you can name this method as you see fit). This way I make sure that the view already exists before you access it via getViewSize.

Hi,

This is working great and now better understood. Appreciated

Currently @cx and @cy are initialized after load. This might contradict saving it in 'flowstones preset' (which I usually use to save VST data like knob and slider values).
Any hints on how to save @cx and @cy from last read - on DAW (like preset auto save mode)?

[tulamide]

If you use this method:

Code: Select all

def init
  #initialize @cx/@cy here
end

the variables will be initialized when the RubyEdit is initialized. They can then be easily overwritten by an input from the preset manager (presets update after load). You do that by extending the already existing event method:

Code: Select all

#assuming there are two inputs named px and py that are sent from the preset
def event i, v
  if i == 'px'
    @cx = v
    redraw
  elsif i == 'py'
    @cy = v
    redraw
  end
end

Does somebody know how to make a loop in ruby for multiple objects?
