Hi Tom Thanks for the explanation. Yeah, I do know a little bit about variables from what I read in a jaws scripting tutorial. In a jaws script, if you want to declare variables you would start with the word var on its own line at the beginning of a script. Then for an integer variable you would write the letters int and a space and then give any word as a name for the variable, as long as it starts with the word int. For example Int column For a text string variable you would write for example: str box If you are specifying more than 1 variable, each variable except the last one, must have a comma at the end. then to declare a variable you would write for instance: let column = 1 or let box = "hello world" then to use the say string or type string function, instead of writing the strings in quotes you can just put for example: saystring box () Does it also work like that in game programming?

Hi Nicol, Okay? Well, I can say right off that creating Algebra formulas is a key part of programming. A formula like p = 2l+2w would calculate the perimitor of a square or rectangle. For example, if we are getting into graphics programming an indepth knowledge of basic geometry is essentual in order to render the graphics on screen properly using those formulas. Anyway, another key concept that carries over is variables which was definitely covered in my Algebra class. In the formula p = 2l+2w the letters p, l, and w are variables because we don't know what numbers/values they contain yet. They are just substitutions or place holders so to speak. Now, if we assume l is 10 and w is 5 we now get a rectangle 10 units long by 5 units wide. We can now do the formula by calculating 2 times l plus 2 times w. After we work the formula we find out that p, the perimitor, is 30. The point I want to get at here is that in any type of programming we use variables to hold values of a keyboard command, numbers, strings, whatever until they are needed. If we don't know what a certain value is we can work a formula to find that out. Understanding variables, therefore, is critical to even beginning to think about programming, because variables are used to store information until it is needed by the program, or use to substitute a value that we don't know yet. That's why I'm saying that at least high school Algebra is pretty much essential to beginning programming. When it comes to game programming it is more so. You have all kinds of formulas such as how to calculate the distance an object has traveled in a certain amount of time, calculating where the objects next location on the grid is, etc. There are hundreds of calculations that goes into any complex game and it requires some kind of familiarity with those concepts before beginning. --- Gamers mailing list __ Gamers@audyssey.org If you want to leave the list, send E-mail to gamers-unsubscr...@audyssey.org.
