Hello,

I was going through Chris's new Memblock explanation and I ran into someplace I couldn't figure out. It was on this page http://www.binarymodular.com/main/articles.php?article_id=75
Chris creates the memblock as a 2 (word, rangeL 0-65535) but then it looks like he fills it with float??? I thought that you had to designate the size of the memblock first? So if he is filling it with 60 floats, how does that work? or does dbpro automatically increase the size of the memblock as needed? and if that is the case, why declare a specific memblock size when you can just declare whatever and increase automatically as needed?

Thanks to all who understand this stuff

What's probably confusing you here is that in the example Chris is using the MAKE MEMBLOCK FROM FILE command which gets the memblock size from the file being used.

The first ten lines of Chris' example code are where this file is created. The float values are being written to this file and then the MAKE MEMBLOCK FROM FILE command uses this file.

The file "Land.dat" should appear in the same folder as the project file.

Have a look in the help file index to find the MAKE MEMBLOCK FROM FILE as for some reason it doesn't appear in the memblock command list.

Hope this makes sense.

Thanks 29 games, I have been working on a few projects and have finally found more time for the site.

I hope the information was useful Bulsatar. I am currently working on more explanations of more memblock commands and have just released a new tutorial in the XML section.

It was very useful! I am coming from a database background so I have the basics, but the more detailed parts of a standard game are still elusive and I need all the help I can get
