Hello. First of all, congratulations to the creator of Vavoom for such a great work <!-- s:) --><img src="{SMILIES_PATH}/icon_smile.gif" alt=":)" title="Smile" /><!-- s:) --> I have some questions about Vavoom C. First of all, is it documented? I mean, is there a reference for it somewhere? Then, I'm trying to make a new projectile in Hexen with graphics (I think) haven't been used in the whole game. The thing is, I want the projectile to spawn fireballs in random directions when it hits. For that, I have based the missile in the code of the "IceGuyMissile", but I have a problem. This is the code:

void A_FlareMissileExplode()
{
	Actor mo;
	int i;

	for (i = 0; i < 12; i++)
	{
		mo = SpawnMissileAngle(FireBall1, itof(i) * 30.0, -0.9 * 35.0);
		if (mo)
		{
			mo.Instigator = Instigator;
		}
	}
}

And I don't understand half of it. I only replaced the shards with fireballs, and twisted the (I think) angle numbers a little. Now, how do I spawn projectiles with gravity? I want the explosion to create an effect like this one I programmed in ACS, but with less fireballs and speed:

int flares;
script 1 ( void )
{
	flares=0;
	while (flares !=70)
	{
		Thing_ProjectileGravity(71, T_FIREBALL1, random(0,255), random(1,120), random(10,60));
		flares = flares+1;
	}
}

Is it possible to do something similar with Vavoom C? If it is, how to? Thank you very much.

Try this one:

void A_FlareMissileExplode() 
{ 
   Actor mo; 
   int i; 

   for (i = 0; i < 12; i++) 
   { 
      mo = SpawnMissileAngle(FireBall1, itof(i) * 30.0, -0.9 * 35.0); 
      if (mo) 
      { 
         mo.bNoGravity = false;
         mo.Instigator = Instigator; 
      } 
   } 
}

You may laso change Fireball's mass: mo.Mass = X.X;

There is some documentation on Vavoom wiki, but it's very incomplete.

...just reminded me... <!-- s:wink: --><img src="{SMILIES_PATH}/icon_wink.gif" alt=":wink:" title="Wink" /><!-- s:wink: --> Maybe I'll write a couple of articles about most used classes like Thinker-Entity-Actor and Player. I suddenly got a question: where Thinker objects are stored?

They are stored in a linked list in Level class.

What is new BeginPlay event in Entity class, I mean when it is called?

For map placed objects it's called immediately after map has been loaded. For objects created later it's called when it's spawned.

How may I safely respawn player? I tried SpawnClient and DeathMatchSpawn but in both cases previous player's MO stayed on map.

Remove the old object first. Or take a look how morphing/unmorphing works.

It was said somewhere (in wiki maybe) that you cannot use "classid Class" variable of class Object. It was true for version 1.18. Is it true for now as well?

I'm not sure, but I think it doesn't works with the current version.

You can use it.

That's what is written in WIKI (date is january 2005):

classid: Represents a class. The actual value is a reference to an object describing class, but currently you can't use it as a Class object.

So, you say now it can be used as Class object (object of class Class?) Honestly, I do not understand this quite enouph. Until now I knew that classid variables may be used to define spawned object type and in conditions like "if (var.Class == Pawn)"... But how it may be used as Class object?

Initially class Class was derived from Object and could be used as such, but it's not anymore. Probably that sentence should be removed.

So, classid is simply class ID and no more?

Yes.
