Actor does not spawn

[rico345]

Code: Select all

script 985 (void){
	MarkX=GetActorX(0);
	MarkY=GetActorY(0);
	MarkZ=GetActorZ(0);
	MarkZCeiling=GetActorCeilingZ(0);
	Delay(35*5);
	Spawn("AmmoBox_Drop",MarkX,MarkY,MarkZCeiling,0);
}

I want spawn Supply Box in the sky.
Just using GetActorZ(0) is working.
But GetActirCeilingZ(0) is not working.

What is problem?

Getting stuck in the ceiling? Try GetActorCeilingZ(0)-32*65536.

What value is returned from GetActorCeilingZ(0)?

Are you sure that GetActorCeilingZ is what doesn't work, and that it isn't spawning an actor with the returned value that fails?

I think the Z in Spawn places the lowest point on the actor you're spawning, meaning that you need some room above it if it cannot spawn just anywhere. If it can spawn just anywhere, use [wiki]SpawnForced[/wiki]. Otherwise, subtract the height of the spawned actor, or (height + 1).

Assuming the actor is 10 "units" tall:

Code: Select all

script 985 (void){
   MarkX=GetActorX(0);
   MarkY=GetActorY(0);
   MarkZ=GetActorZ(0);
   MarkZCeiling=GetActorCeilingZ(0);
   Delay(35*5);

  // Then one of the following:

   Spawn("AmmoBox_Drop",MarkX,MarkY,MarkZCeiling - 10.0,0); // Option A
   Spawn("AmmoBox_Drop",MarkX,MarkY,MarkZCeiling - 11.0,0); // Option B
   SpawnForced("AmmoBox_Drop",MarkX,MarkY,MarkZCeiling,0); // Option C

   Spawn("AmmoBox_Drop",MarkX,MarkY,MarkZCeiling - (1+ 10.0),0); // Option D, slightly convoluted
}

Oh my, thank you.
It's work! What is the problem? I don't know what am I wrong.

thank you for answer.
I feel very grateful to you.

One thing, I have forgot to explain.
My mod is based in Skulltag, so can't use SpawnForced.

And I tried all your suggested ways, but nothing work. Sorry.

But thank you for kindness answer.

"You need some room above it if it cannot spawn just anywhere". GetActorCeilingZ(0)-32*65536 spawns it 32 units below the ceiling (the *65536 converts it to [wiki]Fixed_point[/wiki]).

The following expressions are all the same:
2097152 (integer notation)
32.0 (fixed point notation)
32 * 65536
32<<16

None of the above values are 32. They are all 32 * 65536. When I want a constant fixed point value, I would use fixed point notation. In this case, 32.0 .

Thanks, I understand now.
