Stupid decorate / A_Jump question

[gramps]

I'm sure I'm doing something stupid here, but not sure what.

I have four different tuft-of-grass sprites, and an actor for each. Here are the first two:

Code: Select all

Actor G_Grass1 20401
{
	Radius 8
	Height 8
	States
	{
	Spawn:
		GRS1 A -1
		Stop
	}
}
Actor G_Grass2 20402
{
	Radius 8
	Height 8
	States
	{
	Spawn:
		GRS2 A -1
		Stop
	}
}

These work fine. I wanted to make a new actor that randomly displays one of the frames:

Code: Select all

Actor G_Grass 20400
{
	Radius 8
	Height 8
	States
	{
	Spawn:
		GRS1 A 0 A_Jump(256, 1, 2, 3, 4)
		GRS1 A -1
		GRS2 A -1
		GRS3 A -1
		GRS4 A -1
		Stop
	}
}

But this always shows the GRS1 sprite. Have tried several variations (named states, adding some non-zero-length frames, etc.) and always end up with either the first sprite or no sprite at all. What am I doing wrong here?

Using decorate instead of zscript for Slade compat, btw.

On the state with the A_Jump call, put the [wiki=Actor_states#NoDelay]NoDelay[/wiki] state keyword.

Sweet, lemme try that. Should this be on wiki?

Just tried it, works fine. Not sure I understand what it's doing exactly, why didn't this work after a delay? I guess the A_Jump examples are meant to be partial state blocks and that's why they don't have that NoDelay thing on the first line...

The "NoDelay" in my post is a link to the relevant page on the wiki.

Right, I meant on the wiki page for A_Jump, which I was referencing when I wrote the thing and has several things on the first line with no NoDelay.

Incidentally I don't particularly care if there's a (one tic?) delay or not, and still don't quite understand why not having a delay makes this work, while it doesn't work after a delay.

What exactly is NoDelay doing (besides not delaying) that makes this work when it doesn't work without it?
