Can you print the value of an argument?

Hello,

It would be useful to see what value an argument is currently holding, but at least A_Print doesn't seem to work too well for this.

This code crashes on startup:

 A_Print(args[3])

And if I write this instead...

 A_Print("args[3]")

...it will just print "args_3_" in the game.

Are there any other options?

Arguments are identified by a name. Don't you give names to the arguments in the script's head definition? Such as:

script 1 (int a, int b, int c, int d) {

In the code above, d is your args[3].

EDIT: I'm sorry, disregard the above, I thought you were talking about Print in ACS.

EDIT2: Well, A_Print can only have 3 arguments, so perhaps you have to call args[2]. Args[0] is the 1st argument. Args[3] would be a 4th one.

Sorry, I meant I was trying to achieve this in the decorate code without using scripts, like so:

 TNT1 A 0 A_Print(args[3])
// TNT1 A 0 A_Print("args 3 is currently equal to: " + args[3])

Is scripting the only way to do this, then?

EDIT:

Ok, I've now read your edit above, and tried with args[2], but it crashes on startup as well.

Now I see - my advice above is pretty stupid, because it's not about parameters for A_Print (of course!), but the thing's arguments.

Try to pass all A_Print parameters.

If you're testing the wad with Zandronum source port, try ZDoom, because Zandronum doesn't support some features (yet).

If it fails, I don't know then. I can only recommend ACS script.


EDIT: And also, what exactly do you mean by "crashes on startup"? Is there any error message? Is it startup of a map or the whole wad?

It's the WAD that crashes on startup, because of having 'args[2]' inside the A_Print. The error message says it expected a ',' but got a '[' instead. I guess A_Print can only take strings and nothing else?

Maybe I'll give this another shot using scripts instead, I'll just first have to refresh my memory on those since it's been a while.

It's quite possible, the wiki page implies it.

Print function in ACS is definitely more flexible.

Now trying with this script:

Script "PrintArgument" (int Test)
 {
  print (d:Test);
  Delay(1);
 }

And for testing, I'm using this code in a Ready-state of a weapon:

 Ready:
  CHGG A 1 A_WeaponReady
  TNT1 A 0 A_SetArg(2, args[2]+1)
  TNT1 A 0 ACS_NamedExecute("PrintArgument", 0, args[2])
   Loop

The printed message on the screen doesn't seem to update; it prints "0" once, and doesn't come back after it's faded out, despite being continously called in the looped ready-state. Why is this?

EDIT 1: Nevermind, suddenly it began working (?). Thanks for the help. :-)

EDIT 2: Is it possible to control player's FoV with ACS?
