The "How do I..." Thread

You forgot the "+" by the sounds of it.

Now zdoom crashes every time I fire the weapon.

[TheDarkArchon]

Post the code. It'll be difficult to determine what could be causing the crash without it.

[SamVision]

I decided to redo the weapon entirely and now it works, but thanks anyway.

In WADs with custom monsters that doesn't replace the stock, can I make them use the stock monsters stats?
Say there's this UberPinkyDemon and I'd like him to use the original Demon's stat, should I just write "UberPinkyDemon : Demon replaces Demon" then?

[Blue Shadow]

If you want it to replace the original pinky, then yes. However, if you only want access to its states, properties, etc. but not replace the original monster, then you should omit the "replaces Demon" part.

[LostSkull]

No, I meant the opposite. I want the Uberdemon to use the Demons stats and stuff.

[Blue Shadow]

Your example above will make a new actor that is an exact replica of the original Doom Demon and will replace it in-game. The following line will do just that but won't replace the original monster (you either have to spawn this new monster somehow or place it in the map through a map editor):

Code: Select all

UberPinkyDemon : Demon 11001 {}

This following will make a "new" demon that have as much health as a mancubus while retaining the original demon's stats and everything else:

Code: Select all

UberPinkyDemon : Demon 11001
{
  Health 600
}

Thanks Blue, I think I got it

Thanks Blue, I think I got it

No problem.

How do I let a jumping monster land correctly?

First I tried with A_CheckFloor, but it does not work on top of another actor or on bridges.
So I tried A_JumpIf(velz==0) next, but it also happens in mid-air sometimes, when a monster reaches the highest spot of its jump, just before falling down again.
So I don't know what else I could try now.
Can someone help me?

Does anyone have an idea, please?

Not sure if this is going to help you or not, but two years ago, I modified the Infernal Spider to have some sort of a jump ability. Here:

• Jumpy spider
• A test map for the jumpy spider

How do I give a custom damage type to a hitscan enemie?

(I kinda forgot )

[TheMightyHeracross]

Put it on their bullet puff, not the monster.

[Ravick]

Thanks!

[edit]

Is there an ACS way to remove actors by their type instead of their TID?

[WARCHILD_89]

Hey guys,

I want to have an actor that is spawned by "A_FireCustomMissile", but it should be invisible, make no sound and no damage? The only thing it does is to wake up the monster tha´s being hit by it..... any Suggestions?

[TheMightyHeracross]

If you want an invisible actor, make the sprites TNT1. To omit sound, just leave out the SeeSound/DeathSound/etc. and do the same for Damage to prevent damage.
EDIT: I think you'd be better off doing this with with hitscan, an invisible puff with +PUFFONACTORS to replace Blood and +PAINLESS to prevent pain.
Example:

Code: Select all

ACTOR AlertPuff : BulletPuff
{
+PUFFONACTORS
+PAINLESS
  States
  {
  Spawn:
  TNT1 A 1
  Stop
  }
}

Thanks for help it was a first step but I finally found another way to make the zombiekiller´s flashlight act like I want it to. Monsters can be alerted by being illuminated.
