DVDLabPro: How to you link a button to the 2nd cell of a menu?

[Alain2007]

In DLP, linking buttons to menus is pretty straightforward with drag and drop. But if I am using a menu with 2 cells, how do I tell my button to go to cell #2?

There is a comprehensive section on menu cells in the help file. I suggest you read it. In the short term though, right-click on the button and select Link -> Link to Menu Cell. A dialogue will open that lets you set the cell and the button

Yeah, I read that and I was able to link cell 1 to cell 2 and vice-versa to imitate switched menus. But if I am on an entirely different menu, and i right click to get Link to Menu Cell, it appears to still be only within the same menu. I must admit, I dont quite understand the bit about registering GPRMOs, and maybe if I did, that would shed some light!

If you haven't registered with the MediaChance forums, now is probably a good time. It is the best place to get detailed answers, especially once you start getting into the more complex side of things. When I started playing with multi-cell motion menus I found this post to be a good starting point -> http://www.mmbforums.com/phpbb/viewtopic.php?p=85012#85012
as well as http://www.mmbforums.com/phpbb/viewtopic.php?t=14863&highlight=delayed+cell

They may not be exactly what you need, but the answer is in there.

Thanks for the direction. These postings helped a bit but I still dont understand what GPRM stands for. When I link a button on menu 3 to go to cell 2 of menu 1, how do I know to which number i need to set the GPRM? Does GPRM stand for the destination being called or for the object calling (ie. button)?

If you have ever done any programming then you should understand the concept of variables. If not, a variable is basically a memory location into which you can put values to use later.

A GPRM is basically a memory location reserved for your use. There are 16 General Parameter (GPRM) registers available for you to use when creating complex menus, and 24 System Parameters (SPRM) used to store specific information about the DVD itself. You can read from, but not write to, SPRM registers. You can read from and write to GPRM registers. Top complicate things a little further, DLP reserves the GPRMs 10 - 15 for it's own use, leaving you 0 - 9 for user menus.

You can use GPRM registers to keep track of where you came from, to make sure you return to the same place, or as temporary storage for keeping score in a game.

Have a read of the section on VM Commands in the help file. It doesn't matter if you don't have a full grasp of how they work (I know I don't) - there should be enough in those posts to get you going.
