hi, i have a text field that is populated by a datalinq. when the text in that field changes, i'd like the original text to fade off, and the new text fade on.  whats the best way to achieve this?

thanks.

Hi James,

First of all, you can not do this on the Datalinq'ed textfield directly. Whenever the value changes it will be reflected instantly in the textfield so fading out the old text and fading in the new text is not possible on the textfield itself.

However, you can achieve this using a dummy textfield and some scripting.

So you would need two separate textfields. One dummy field which can be hidden and which is updated using Datalinq and a second textfield which will fade out, update the text and fade back in again.

So on the dummy textfield you need to set up the Datalinq but you also need to set up a script event on that textfield using the OnSetText-script.

The script you would need is below.

dim content as string = Text
dim txtObj as xpTextObject

' LINK THE TEXT OBJECT THAT NEEDS TO FADE
Scene.GetObjectByName("fadeText", txtObj)

' FADE OUT THE CURRENT TEXTFIELD
txtObj.FadeRange(100,0,50,0,true)

' UPDATE THE CONTENT OF THE TEXTFIELD
txtObj.Text = content

' FADE IN THE TEXTFIELD AGAIN
txtObj.FadeRange(0,100,50)

Some values that you need to change according to your needs:

"fadeText" => this is the name of the field that needs to fade in.

txtObj.FadeRange(100,0,50,0,true) => the value of 50 determines the duration of the fade out. In this case 50 frames.

txtObj.FadeRange(0,100,50) => the value of 50 determines the duration of the fade in. In this case 50 frames.

Best regards,
