It declares the variable before it as a DWORD, which is basically an unsigned long integer (Double WORD). It has a range of 0 to 4294967295.

Depends on what you`ll need the variable.The program need know what type is variable, so it can work with it.With integers you`ll store a lot of stuff in your game, mana , health, damage etc, most of the time coordinates you get from object in 3D space are floats, string you use for any kind of text.And so on.There is pretty good explanation in the help files of dbpro.Start with them.Then move on some tutorials, try examples, modify and you`ll understand everything.

Where there is a will, there is a way.
I often edit my posts, that`s who i am

Dwords, floats, booleans, strings, etc. are all data types. They control how your program determines what type of information and how it is stored inside a variable. Press F1 inside DBP and navigate to "Principles" then "Datatypes and variables" to get a more in depth description.

Here are some samples:

DWYitzu as DWORD
StrYitzu$ as String
IntYitzu as Integer
FloYitzu as Float
BooYitzu as Boolean

Everything in bold is a variable. The "as DWord", "as String", etc just tells your program what kind of variable it is.



EDIT: Actually, I think the correct word usage I should use is: The "as DWord", "as String", etc just tells your program what kind of data your variable will hold.

It is my understanding that when you declare a variable, it stores its information in your memory (actually, I think it sets aside an amount equal to the maximum size of the type of variable dependless on whether it has information in it or not.) A boolean will store a 0 or a 1 which will take a lot less memory than storing a float. It's not such a huge deal with a smaller game, but with more intensive games, you will definitely need take this into consideration.
