Code: Select all

Skybox MYSKY
{
  SKYN
  SKYE
  SKYS
  SKYW
  SKYT
  SKYB
}

Yes, you need to set your map to use the "MYSKY" sky since it's the name of your GL skybox.

Can you elaborate? Will it be like this?

Code: Select all

map MAP01 "Fancy name" {
	Sky1 = "MYSKY", 0
}

[Gez]

Yes.

[Andie]

Everything works now, thank you.

How do I place a camera texture on a floor? I've tried the steps for textures in wiki:SetCameraToTexture, but I get a corrupted mess of columns. Works fine on wall textures but I mean to place it on a slope. Is there a way for flats? I'm using software rendering and Zdoom Doom in Hexen format.

SOLVED: Use a power-of-two texture.

How to correctly make a monster aim at the player with ZDoom's "spawnofs_z"?

Code: Select all

     SKLL K 0 A_CustomRailgun (10,12,none,red,0,1,0,0,0,0,0,0,0,0,0,30)
     SKLL K 0 A_CustomRailgun (10,-12,none,red,0,1,0,0,0,0,0,0,0,0,0,30)

A screen will explain the problem:

Sorry for bothering with another problem, especially because it's about scripting. I "simply" want to transfer an actor's pointers toward one of its summonings.
It means, let's say there is an actor A and actor B. The actor A has the target "actor X". The actor B can't target the "actor X", but it has targetted actor A so it'll need a script to copy its target's target (this means actor A's target). Actor A's target is actor X.

Now if I'm requesting a script, it's because neither A_SpawnItemEx's SXF_TRANSFERPOINTERS flag, neither A_TransferPointers and A_ReorganisePointers work. It's like if they don't seem to exist (it causes a fatal error "invalid state parameter" when I launch the game).
Thank you in advance for any help

[Blue Shadow]

Could you post the code so we can see what's wrong?

[Stardust]

Yes, here it is, through disregarding which actor has the SpawnItemEx pointer transfer flag or the ReorganisePointer action, it won't work. I'm pretty sure it has nothing to do with the actor's behavior, after all everyone could use at any moment a SpawnItemEx, right ?

Here's a random actor that would cause the same error message (see pictures) as any other actor that has the SpawnItemEx flag or pointer transfer stuff.

You are using the angle argument for your flags in A_SpawnItemEx.

Code: Select all

A_SpawnItemEx("StardustStardustRedHigh", 0, -80, 0, 0, 0, 0, SXF_TRANSFERPOINTERS)

should be:

Code: Select all

A_SpawnItemEx("StardustStardustRedHigh", 0, -80, 0, 0, 0, 0, 0, SXF_TRANSFERPOINTERS)

If this is for Zandronum, I have no idea if A_RearrangePointers even works.

[Stardust]

No I'm not :3 the fields to fill of SpawnItemEx are so easy to remember because this function's so common : X Y Z position, and then X Y Z speed. And then the 7th thing is about angle and 8th about flags.
Anyway I had some help IIRC, they said Zandronum just CAN'T make it work. As you guessed
Through problem solved, thanks again everyone

[KingShinra]

Sincerest apologies. Didn't know there was a thread like this.

I want to build a script that, when Doomguy kills 12 enemies (All Tagged 1000), a sector rises with a switch to lower some bars that block the path ahead.

How would I write it. Once I have it, I'll keep it in an ACS library and study it. Help is definitely appreciated.

[cocka]

Simple:

Code: Select all

script 1 (void)
{
	until(ThingCount(T_NONE, 1000) == 0)
	{
	delay(3);
	}
	Floor_RaiseByValue(tag, speed, height);
}

[KingShinra]

Thanks Cocka. Much appreciated!

EDIT: Code seems right, but the floor isn't raising after I kill the monsters. Copied the code verbatim.

Anything else that might be wrong?

[BloodyAcid]

The script type should be open instead of void I think. When it's (void), you've nothing triggering the check.

[cocka]

When it's (void), you've nothing triggering the check.

He didn't write anything about that. I suppose he just drew a line and assigned a script execute action special to it.

Copied the code verbatim.

Really?

Floor_RaiseByValue(tag, speed, height);

I wrote in this form because I thought you could fill in the named parameters logically.
