ZDoom

Random2 is basically just random() - random(), i.e. it subtracts a random byte value from another random byte value.

It effectively creates a random number between -255 and 255 with the central values more likely.

Can someone please tell me how random2 is used? It looks as if it should be pretty useful but I can't figure its full implications out by looking at the DECORATE code in zdoom.pk3 and I can't find an explanation in the Wiki or on the forum.

Same bug. All random2 calls from DECORATE were broken.

And the CrossbowFX2 actor also doesn't spawn a trail. All of these use A_SpawnItemEx using "random2" as part of its parameters. Related?

[edit] That was a cross post [/edit]

Fixed. It got accidentally altered by a careless search & replace.

Also fixed. When Randy added the new RNG code the Random2(int mask) version got changed from returning the difference between 2 bytes to the difference between 2 ints.

In addition, I just noticed that the Beast Monster's fireball no longer has a trail either. I *think* this uses the same DECORATE code as the volcano fireball to spawn its trail.

I just noticed 2 problems with the Heretic Volcano items.

1) When it launches a fireball, no sound is played. There is one in Vanilla Heretic. I think that this used to work in Zdoom a while back [edit] yes, it works in 1.23 b33 [/edit] however recent Zdooms do not play the sound - even as far back as the last official Zdoom. The sound "world/volcano/shoot" is defined but I don't see anything calling it.

2) The launched fireballs don't have a trail. I'm not sure why this doesn't work as there seems to be DECORATE code for it. What's more, it was working up until fairly recently. The last official GZdoom has the trails but neither the current Zdoom nor GZdoom revisions do.
