Hi,

If I have OpusScript e.g.

Object1.Show();
Object2.Show();

// but I want them to show simultaneously, how is the script written?


Steve

I have done this before by using fork. First create a function like this

function DisplayObject()
{
this.Show();
}

then to show the objects

fork(DisplayObject, Object1);
fork(DisplayObject, Object2);

Hi Tony,

Thanks for this example as after reading the Script HELP file, it made things easier to understand.

I noticed that a Script Object is required. So I wanted to create a script action on a button and not have the Script Object show the objects as the page displayed.

What I did was this...

// SCRIPT OBJECT //

function DisplayObject()
{
this.Show();
}

function ShowBoth()
{
fork(DisplayObject, Object1);
fork(DisplayObject, Object2);
}


// Then on the button for the script action I entered:

ShowBoth()

// This seemed to work fine.

After experimenting with 'fork' I realised that 'this' could not be used for other functions, so after testing various examples I found that instead of using this.Show() I could use...

function DisplayObject()
{
Object1.Show();
Object2.Show();
}
function ShowBoth()
{
fork(DisplayObject, Object1);
fork(DisplayObject, Object2);
}

// I hope I've got this all right!

With the code above you are telling both object to show twice. The first fork will start showing Object1 then when that has finished show Object2. But the second fork calls show for Object1 but as it has started showing it returns straight away and starts showing Object2. This does work but is doing more work than it really needs to. Also you don't need to pass the objects as the parameter to fork so you could just do this.
fork(DisplayObject);
fork(DisplayObject);
The reason I passed it in my example is that the object pass is then the this object.



I am not sure what you were trying to do here and why this could not be used. Have you got an example?

Hi Tony,

I know 'this' could be used for Show(), but thought it could not be used for e.g. animations.

I looked in the HELP file and saw how 'this' was not used in the script example for Show() and Hide() together, so tried applying that method to other variations. Please bear in mind I am only experimenting, and thought the discussion of "Simutaneous Actions" (fork in script) could be perhaps a discussion to kick off on this new forum. (plus I need to learn)

Have a look in the following on why I did not use the 'this' keyword...

function DisplayPath()
{
Star1.FollowPath(Path1, 4, false, false, 0, 100)
}
function DisplayRotate()
{
Star1.Rotate(360,4)
}
function ShowAnimations()
{
fork(DisplayPath)
fork(DisplayRotate)
}

// The function called on an action on a button was:
// ShowAnimations()


Now I know you're going to say 'fork' is not needed, as I could simply make the default wait command from 'true' to 'false' on the FollowPath(), but I was simply experimenting and trying to learn setting out OpusScripting using 'fork'.

I guess I could simply have done the following on a script action...

Star1.FollowPath(Path1, 4, false, false, 0, 100, false);
Star1.Rotate(360,4)

// and not even needed to call a function.

You could have used 'this' if you wrote the code like this

function DisplayPath()
{
this.FollowPath(Path1, 4, false, false, 0, 100)
}
function DisplayRotate()
{
this.Rotate(360,4)
}
function ShowAnimations()
{
fork(DisplayPath, Star1)
fork(DisplayRotate, Star1)
}

This way you could reuse the DisplayPath() and DisplayRotate() functions again but with different objects e.g.

fork(DisplayPath, Square1)
fork(DisplayRotate, Square1)

Thanks for this Tony,

I found that I could combine actions in your fork example at the end...

{
fork(DisplayPath, Square1)
fork(DisplayRotate, Square1)
fork(DisplayPath, Star1)
fork(DisplayRotate, Star1)
}

// then even the following worked..

{
fork(DisplayPath, Square1)
fork(DisplayRotate, Square1)
wait(1)
fork(DisplayPath, Star1)
fork(DisplayRotate, Star1)
}

// I experimented thus more...

{
fork(DisplayPath, Square1)
fork(DisplayRotate, Square1)
fork(DisplayPath, Star1)
if (MyVariable = 0)
{ fork(DisplayRotate, Star1) }
}


Thanks for all your help.
