Hi:

Maybe reconsider your use case.
BOY (EDM, MEDM, ..) work best if you use them as originally intended:
1) Add suitable widget
2) Set PV name
Done.

In BOY, you can use scripts to handle some very special cases, but the portability of scripts cannot be guaranteed through updates of the software and will certainly be slower than using any of the built-in functionality.
If you want a circle that changes color, don’t use a circle with rule or script but instead use the LED widget.
If you want a text that changes content, don’t use a Label w/ rule/script but instead use a TextUpdate widget.
To change displays, use buttons that allow operators to open related displays.

If absolutely have to create a video game:
Use a linking container, and set the “opi_file” property of that one in a script based on your PV.
--> PV will determine what’s displayed inside the linking container.
Like this:

# Script for LinkingContainer that shows either A.opi or B.opi
#
# pvs[0]: PV like sim://sine that changes positive/negative
from org.csstudio.opibuilder.scriptUtil import PVUtil
if PVUtil.getDouble(pvs[0]) > 0:
   widget.setPropertyValue("opi_file", "A.opi")
else:
   widget.setPropertyValue("opi_file", "B.opi")
