Spawn() failure

[LilWhiteMouse]

What would cause Spawn() to fail in an open space? I'm using Spawn() to have my ED-209 monster spawn it's parts. It works fine in stock Doom 2 maps, but when I summon the monster in a custom map, it fails.

[EDIT] I did a little testing, and I know Spawn() is getting the right coordinates, it just refuses to spawn the actors in any of the custom maps I've tried.

Does it have enough room to spawn?

Do you have the coordinates in fixed point, ie 720.0 instead of 720?

A snippet of the ACS that the main actor runs:

Code: Select all

function int GetFreeTID (int start)
{
	//while (ThingCount (0, start) != 0){start++;}
	while (GetActorViewHeight(start) + ThingCount (0, start) != 0){start++;}
	return start;
}

script 500 (void) {
if (ActivatorTID() != 0){terminate;}
if (ActivatorTID() == 0){Thing_ChangeTID(0, GetFreeTID(500));}
int LegL = GetFreeTID(500);
Spawn ("ED209_Leg1", GetActorX(0), GetActorY(0), GetActorZ(0), LegL, 0);

GetFreeTID() works, and the GetActor positions are working, it just refuses to spawn when in any custom map I've tried. I just don't understand why it would work on Doom 2 maps, but not any custom maps. The script itself is executes just fine on custom maps, it's just the spawn()s that fail.

A look at the leg, though none of the actors spawn:

---

Code: Select all

ACTOR ED209_Leg1
{
	+NOGRAVITY
	+SHOOTABLE
	+NOBLOOD
	+GHOST
	Radius 16
	Height 48
	Mass 10000
	Scale 0.33
	Health 750
	States
	{
	Spawn:
		EDLG AA -1
		stop
	See:
		EDLG A 0 A_PlaySoundEX ("ED209_Servo", Body)
		EDLG ABC 6 A_Stop
		EDLG D 0 A_PlaySoundEX ("ED209_Step", Weapon)
		EDLG DEF 6 A_Stop
		loop
	Death:
		EDLG GGG 3 A_SpawnItemEX ("ED209_ExplodeDeath", random (-8, 8), random (-8, 8), random (8, 56))
		goto DeathLoop
	DeathLoop:
		EDLG G 0 A_Jump (240, 2)
		EDLG G 0 A_SpawnItemEX ("ED209_Spark", random (-8, 8), random (-8, 8), random (8, 56))
		EDLG G 4 A_Stop
		loop
	}
}

[EDIT] I tried replacing Spawn ("ED209_Leg1", GetActorX(0), GetActorY(0), GetActorZ(0), LegL, 0) with SpawnSpot("ED209_Leg1", 0, LegL, 0) and SpawnSpot("ED209_Leg1", ActivatorTID(), LegL, 0) but no change. It worked on a stock map, but failed on a custom map.

are you sure it's reaching the spawn line?

Yes, the whole script runs as expected, it's just the parts won't spawn outside of stock maps. I wrote in printbold()s to check each step of the script.

Did you remember to declare the script as a library?

YAY! No, I didn't. That fixed it. So why does it work in stock maps? Because they don't have any scripts?

Exactly.

Here's a trick I like to use when testing the success of Spawn().

Code: Select all

  int test = Spawn(class, x, y, z, new_tid, angle);
  if (!test)
  {
    //do stuff if Spawn() failed
    PrintBold(s:class, s:" failed to spawn at coordinates ", f:x, s:", ", f:y, s:", ", f:z);
  }
