"Random" titlemaps?

[Ceeb]

I want to have several different titlemaps in my mod, or at least a way to have different views in the same map. How would I achieve that effect with an ACS script?

[Medricel]

Set up cameras in the areas you want to show, then use [wiki]ChangeCamera[/wiki] in a script to cycle through views of the map.

Hmmm, this brings up a question: Can you use scripts to change maps in a titlemap, or will they simply be ignored?

e.g.:

Code: Select all

script 1 OPEN { // Select a random map
     Teleport_NewMap(random(70, 75), 0, 0);
}

I'll make a test wad and see if it works...

EDIT: i've tried something similar to what Hotwax suggested, and the script is parsed and executed, but for an unknown reason, it doesn't teleport to the last array number...

I'll post the example wad; i hope someone can explain this.

I'd suggest something like this:

Code: Select all

script 100 OPEN
{
	int titlecase;
	titlcase=random(1,5)

	if(titlecase==1)
	{
		//scripts for case 1 here, for example camera viewpoints,
		//hudmessages or whatelse you need
	}
	if(titlecase==2)
	{
		//scripts for case 2
	}
	[..]
	if(titlecase==5)
	{
		//scripts for case 5
	}
}

I'd suggest something like this:

That works, but I'd recommend using the switch command instead. It's a powerful command that does the job of several if X = blah lines and thus reduces redundancy and makes the code look cleaner. Here's your example using a switch statement:

Code: Select all

switch(random(1, 5)) {
     case 1:
          // scripts for case 1 here
          break;
     case 2:
          // scripts for case 2
          break;
     [..]
     case 5:
          // scripts for case 5
          break;
}

In addition, you can also make a default block which is executed if none of the other cases catch the result. And to further reduce redundancy, you can make multiple cases execute the same code. Thus:

Code: Select all

switch (random(1, 7)) {
     case 1:
          // Only executed for result of 1
     case 2:
          // Executed for a result of 1 OR 2 (note the lack of a break statement in case 1)
          break;
     case 3:
     case 5:
          // Executed for a result of 3 or 5.
          break;
     default:
          // Executed for any other value (4, 6 or 7 in this example)
          break;
}

EDIT: i've tried something similar to what Hotwax suggested, and the script is parsed and executed, but for an unknown reason, it doesn't teleport to the last array number...

I can't check the map right now, but that sounds like you might be using an array incorrectly. Arrays are 0-index, which means they start counting at 0 and end at one less than the declared array size.

For example, if you have an arry defined like this:

Code: Select all

int A[3] = { "Hello", 7, 3.1415 };

"Hello" is actually A[0], not A[1] (which is 7). A[2] is 3.1415 and A[3] doesn't exist.

If you were to create code to pick one of these 3 values at random, it should look like this:

Code: Select all

int B = A[random(0, 2)];

Just a shot in the dark.

I did that but I always end up doing it that way out of bad habits. I really should start using it because in theory it will make my wad smaller!
