Include during runtime in Scripts

[SvenK]

Hello,

is it possible to include scripts during runtime? In JScript you have to do

Code: [Select]

!INC foo.bar
However, neither of the following works:

Code: [Select]

if (something)
{
  !INC foo.bar
}


Code: [Select]

eval("!INC foo.bar")

AFAIK EA uses '!INC' to include the actual script -prior to feeding it to a scripting enigne-, so language constructs like 'eval' wouldn't work.

But what are you trying to achieve by this?

But what are you trying to achieve by this?

I want to include some files only once.

Assume a script A creates a variable myvariable= new Object().

Another script B adds something to this variable: myvariable.number=10

If at another place script A is again included, myvariable is overwritten...

While writing this, I think I may introduce some kind of include-guard to solve the problem.

EA will not include the same script twice, so in your example if you include B in a script X, and subsequently A in the same script X, than this second include of A is ignored and the changes made in B will be visible to X.

If you have several scripts that share 'myvariable' as a common global variable only declare the global variable in A and either create/initialize the variable in the script you know will run first, or have each script that uses it check for existence first, like so:

Code: [Select]

!inc A

...
if (myvariable == undefined){
   myvariable= new Object()
}
myvariable.number=10
...

I wasn't aware of that. So my concerns were if superfluous. Thanks for the clarification.
