Increase height by X pixels

leiafee · **Posted:** November 30th, 2004, 5:17 pm

Can't seem to find a way in standard actions which seem to only use scale by percentage.

Is there a script function which would do it?

How could I have an object which increases by say 50 pixels every time it was clicked?

Hi,

Thank you for your enquiry.

The SetObjectSize() function would probably be most suitable for your requirements. Try applying the following script actions to a Left Mouse Click on the object you wish to change:

Code:

width = this.GetWidth()
height = this.GetHeight()
this.SetObjectSize(width,height+50)

This will cause the clicked object to increase in height by 50 pixels every time it is clicked, without affecting the width.

I hope this helps. Please do not hesitate to contact me if you have any further queries.

Kind regards,

Just the job.

An addendum.

Does SetObjectHeight not work in Flex? And is there a possible workaround if it doesn't?

try this code instead for flex.

this will change the height by nPixels(in the example it is set to 50 pixels)

Code:

nPixels = 50
displaydata = object.GetDisplayData()
height = (object.GetHeight()*displaydata.scaley)/100
ScaleV = (height+nPixels)/height
object.SetScaleV(ScaleV)

alternatively to change the width by nPixels...

Code:

nPixels = 50
displaydata = object.GetDisplayData()
width = (object.GetWidth()*displaydata.scalex)/100
ScaleH = (width+nPixels)/width
object.SetScaleH(ScaleH)

hope this helps.....

Almost, but it only works the first time I click it. I need it to work repeatedly.

sorry, my mistake - i should try it beyond one step next time.

rather than divide by the current height of the object every time you need to divide by the original height of the object to get the new percentage

here's the corrected code.....

Code:

nPixels = 50 
displaydata = object.GetDisplayData() 
org_height = object.GetHeight(); //the object's original height
height = (org_height*displaydata.scaley)/100 // calculate the current pixel height
    // the next line is used to calculate the new scale
    // (current height + our pixel change)/original height
ScaleV = (height+nPixels)/org_height
object.SetScaleV(ScaleV)

i'll leave the width one for you to work out yourself should you need it.
