[Fixed] DECALDEF bug...

[Nash]

Hello, last night while I was creating some new decals, I encountered this problem.

(I would post the problem wad but I don't have a copy of it right now. I'm using a local computer at a cybercafe)

I'll try to post a makeshift DECALDEF.

Code: Select all

decal Flare // this is supposed to be a yellow thingy that fades away slowly
{
blabla
animator GoAway // i have the "flare" use the built-in GoAway animator.
LowerDecal BulletChip
}

decal BulletChip1
{
blabla
}

// ... (all the way to BulletChip5)

// (and then the decalgroup BulletChip which should randomize between the five bullet decals)

// THEN at the bottom, under generators, I set the hitscan weapons' decals to Flare.

Logically, this is what I think is supposed to happen...

When a bullet hits the wall, the flare decal (it's just a single decal, not grouped or whatever) would be drawn... and then it'll call the BulletChip group so that one of the five bullet chips will be drawn randomly under the flare. Right?

But what happens is this: it draws the flare, and it does call the bulletchip to be drawn under it, but it doesn't randomize the chip decals. The same bullet chip will ALWAYS appear no matter how many times you shoot. :(

I will try to somehow post the file here but in the meantime, can anyone sort of reproduce this and investigate the problem?

Two months later, and you haven't added anything. Does that mean you figured it out?

I only read this now but I have to say I had the same feeling with the BFG decal. I always saw the same one but I really didn't think much about the fact that there are actually 2 of them. I just did a little debugging myself and I think I found the cause.
To set the lower decal this function is called:

Code: Select all

const FDecal *FDecalLib::GetDecalByName (const char *name) const
{
	if (name == NULL)
	{
		return NULL;
	}
	FDecalBase *base = ScanTreeForName (name, Root);
	if (base != NULL)
	{
		return base->GetDecal ();
	}
	return NULL;
}

The call to base->GetDecal() actually chooses one of the decals in the group so the group never gets set as lower decal.

Fixed.
