Constants Available to the whole script?

Can this be done?  Right now I'm just creating some variable and putting them in each function that needs them so I can change values relatively easily.  Would be nicer to have one central area to put them though. THanks!

You just define them at the top of the script outside any function.

Riley D. said: Alex is correct. An example might be: //At the top of your script. var MAX_DISTANCE = 50; // <snip>, later on down the script on("change:graphic", function(obj) {     //You can do something with MAX_DISTANCE here... }); In addition, remember that *all* your scripts run in the same context (scope), so you if you define MAX_DISTANCE at the top of one script, you can use it any script. Likewise if you overwrite MAX_DISTANCE with a different value in one script, it will affect all of them. As long as the script you define it in is before the one you use it in.

Doh!  I was putting them inside the main calling event thinking all the other functions, etc. would see the variables.  Glad its so simple! :)

So if your very first script has simply a bunch of variables then all your scripts will be able to use them?  Kinda like an include file I guess.

Yeah, once I have a better handle on all this, I'm gonna make my first script be the include file and put all kinds of variables and functions in there.

Coming from an OOP background I have 6 include scripts each with a "class" (javascript doesn't have classes but has things like them) in it and I have one main script that has all the events in it and makes calls to the classes.

Don't like to double post but just to be clear there are no constants in javascript I'm not sure if you wanted true constants or not but I thought I would point that out. A constant is a variable that is set once and can't be changed if you want to signify to other programers that something is a constant in javascript its best to make the name all caps ie: var MYCONSTANT = 42; This way they should know its expected to never change.

I found that out in my research googling.  :)  Only variables and make any that are pseudo constants all Caps!  Gotcha. Thanks

I guess this could be a potential problem when users start really sharing scripts.  One script could use the same "Constant" name as another.  Also when taking commands from the chat window two scripts might use the same commands and the user doesn't know.

ahha!  I see, very nice.  I will do that for sure!  I love it.  Learning lots.  I was thinking for commands from the chat window I would put a few letters in from of the command to denote the script, but don't want the command to get too long. :) !cwsdr killercart Car Wars Steep Drift Right killerkart So as long as no one starts their commands with cw I should be alright. Thanks again Riley  You have been very helpful with my beginner questions! PS: I think I'll change it to Vehicle Combat.  We don't want a letter from Steve Jackson's laywers.  He is very strict with his copyrights, although somehow Vassal gets away with it for years.  Another VTT tried to put out an artpack to help use car wars with his VTT and the lawyers said no way.  I couldn't understand that one in the least actually. Sorry for the digression to another topic! :)
