I played game SpeelBinder made by OriginialWij

When i at outside house i saw the roof ,but when i enter the house the roof is gone and there is room in it and when i go out again i saw the roof come back 

this is script or event ?
i really need it

that's all ,tq for your attention

The roofs are all pre-made pictures. When you enter the house, the picture is hidden ... and when you leave, the picture is shown again. The pictures stay in place through the use of a 'fix picture to position' script, so look at Modern Algebra's Fix Picture script to do the same thing. Or use OriginalWij's Fixed Pictures scriplet, which has less features than MA's script, but it works just fine.

Thanks for help me 
but at thread from MA there's no demo ,and at demo original wij , i don't understand where's the true script

can you make a demo for me ?
hehe
