The "How do I..." Thread

[Accensus]

Much better. Many thanks, you guys!

What I would do for the line is define a universal integer (so outside any scripts) and have the necessary script increment the integer. Then you can have the line's script check if the integer has been incremented and end itself without doing anything if it hasn't.
Example:

Code: Select all

int test = 0;
script "prereq" (void)
{
//stuff this script does;
test++;
}
script "LineTeleport" (void)
{
if (test == 1)
{
Teleport(/*You know what goes here.*/)
}
}

Not a compatmode, but you can set [wiki]compatibility options[/wiki] in MAPINFO, yes. For instance, if you want things to be infinitely vertical for collisions, add that line in the map definition.

Code: Select all

compat_nopassover

Inversely, if you want to make sure it is off, use this line:

Code: Select all

compat_nopassover = 0

IIRC that should work.

Thank you, I'll give that a try!

Is there any way to have a projectile with the +BLOODSPLATTER flag always spawn blood? As it is, it only does so 2/3rds of the time, and having the projectile directly spawn its own blood using A_SpawnItemEX doesn't take the monster's blood color into account.

I'm trying to use the actor state for-loop for the first time:

Code: Select all

Fire:
 TNT1 A 0
  {
   for (  A_SetUserVar(user_i, 0); user_i < 360; A_SetUserVar(user_i, user_i + 45)  )
    {
     A_FireBullets ( user_i, user_i, -1, 10);
    }
  }
 ...

This sometimes freezes the game (with loads of ricochet sounds coming from the bullet puff actor), and sometimes simply produces no shots fired. What am I doing wrong? I have written "var int user_i;" in the weapon definition.

[worldendDominator]

First argument of A_SetUserVar is a string containing uservar name, so you need to put it in quotes.

[D2JK]

Someone should correct that in the wiki (the for-loop section in actor states - page).

And unfortunately, that didn't solve the problem. But I managed to create another test case where the freeze doesn't occur, so I was able to read an error message:

"VM execution aborted: invalid self pointer".

[worldendDominator]

What are you trying to do, in the first place? Shoot 8 bullets with increasing spread?

Also, does that freeze/crash happen if you do it via a state loop rather than anonymous function?

[D2JK]

No, I'm just simplifying my manual circular pattern code, replacing it by the use of sin/cos expressions along with FBF_EXPLICITANGLE flag.

Well, the state loop you suggested crashed as well, but I found the cause; for some reason the user variable wasn't incrementing properly (or maybe there's some sort of upper limit I've forgotten), so it never reached the end condition. This, coupled with zero-tic duration of the looped action produced the freeze, of course.

So I switched to args, and it worked like a charm right off the bat:

Code: Select all

for (A_SetArg(4, 0); args[4] < 360; A_SetArg(4, args[4] + 45))

Hey, I have two customdeaths for the player using 2 'NewDoomPlayer's

whenever Hiro get's killed by an imp,

this happens:

KEYCONF:

Code: Select all

clearplayerclasses
addplayerclass NewDoomPlayer1

DECORATE:

Code: Select all

ACTOR NewDoomPlayer1 : DoomPlayer replaces DoomPlayer
{
+NOSKIN
States
  {
  Death.DalekBall:
    LASD A 3 bright
	PLAY G 2 A_PlayerScream
	LASD A 3 bright
	PLAY G 2
	LASD A 3 bright
	PLAY G 2
	LASD A 3 bright
	PLAY G 2
    PLAY H 10
    PLAY I 10
    PLAY J 10 A_NoBlocking
    PLAY KLM 10
    PLAY N -1
    Stop
	}
}

and when Hiro get's killed by Vader's lightsaber...

KEYCONDEF:

Code: Select all

clearplayerclasses
addplayerclass NewDoomPlayer2

DECORATE:

Code: Select all

ACTOR NewDoomPlayer2 : DoomPlayer replaces DoomPlayer
{
+NOSKIN
States
  {
  Death.VaderMelee:
	PLVD A 2 A_PlaySound ("player/vaderkillmelee")
	PLVD B 0 A_SpawnItemEx("HiroHead", 0, 0, 40, random(2,4), random(2,4), random(2,4), random(0,360), 161)
	PLVD B 14 bright
    PLVD C 8
    PLVD D 8
    PLVD E 8
    PLVD F 8 A_NoBlocking
	PLVD GG 8
    PLVD G -1
    Stop
	}
}

Actor HiroHead

  Radius 11

  Speed 0
  Damage 0
  Projectile
  BounceType "Doom"
  -NOGRAVITY
  +DOOMBOUNCE

  States
  {
  Spawn:
    HHHD ABCDEFGH 4
    loop
  Death:
    HHHD I -1
    stop
  }
}

NOW... Here's the problem...

when I inserted Vadder death code, the dalek death code would not work.

I figured it had to do with the KEYCONF, so I tried two things:

1. Put

Code: Select all

clearplayerclasses
addplayerclass NewDoomPlayer1

and

Code: Select all

clearplayerclasses
addplayerclass NewDoomPlayer2

in the same KEYCONF Text File.

AND

2.

put

Code: Select all

clearplayerclasses
addplayerclass NewDoomPlayer1

AND

Code: Select all

clearplayerclasses
addplayerclass NewDoomPlayer2

in Two different KEYCONF text files.

Neither gave any Avail, mostly, the 'NewDoomplayer1' Dalek Death would not be in the game, but the Vader one would. What's Happening?

Please upload a WAD file for us to look at. Your instructions are not enough to reproduce the problem.

I'm only going to give you the main problem part, the main wad file is, well... let's just say...

HUGE...

First off, how do I send a file through Dropbox?

second, when you get the wad file, the two KEYCONFs are in the same text file.

try that, make sure you will not get a 'select class' menu

if that happens, try splitting the KEYCONFs of NewDoomPlayer1 and NewDoomPlayer2 into two different KEYCONF text files.

[jpalomo]

I'd avoid using KEYCONF to add your player classes. Mapinfo is the way to go. As for your extra death states, why not place them in the same actor?

[arookas]

Would the problem be that you're putting each new death animation in its own player class? The player can only be one player class at a time. Try putting both death states in the same player class.

How do I use it in MAPINFO? Put them in the same Actor?

that's what I'm trying to do, put both death states in the same player, whenever Hiro gets killed by a certian attack, it has it's own death animation (Like BD has different death states.) Also, what do you mean by putting it in it's own player class?

I would lend you the WAD that has the problem, but It's a bit big. (two monsters, 1 player)
