Is it possible to define constants? [solved]

#1 Not really - the engine uses globals as "constants" all the time; just don't change the value....

You can add them from the C++ side though - just expose a console variable with logic in the setter to only allow the value to be set once, or make it an actual const variable and expose it.

#2 Okay, thanks.

I did used the global approach and discovered that I could use them pretty much as constants. For example this code works:

$kGoodsState_Position = 0;
$kGoodsState_Enter    = 1;
$kGoodsState_Transit  = 2;
$kGoodsState_Exit     = 3;

switch(%this.State) {
    
  case $kGoodsState_Position :

  case $kGoodsState_Enter :

  case $kGoodsState_Transit :

  case $kGoodsState_Exit :

}

#3 In order to clarify things you could name them something like this:

$Constant::GoodState_Position = 0;
$Constant::GoodState_Enter = 1;
$Constant::GoodState_Transit = 2;
$Constant::GoodStatt_Exit = 3;

or some other scheme. Helps keep things organized and identifiable.

#4 Good point!
I will use this solution :)

Thank you.
