This is a CODEF add-in library which allows you to call a Pompey Packer v1.9 decrunch effect!
EDIT: I have added a new parameter, so you can choose a white on black screen, or a black on white (as per the picture above).
myPPDecrunch = new PPDecrunch(150,500,1);
The 150 as above is the delay before the decrunch starts
The 500 as above is how long the decrunch lasts for
The 1 is for a WHITE on black decrunch - change to a 0 for BLACK on white decrunch.
A simple little test to show you how to use it is below... Enjoy!
