The "How do I..." Thread

Put it in the Fire state, not the Flash state - you can always just have it happen as a zero-duration frame right before A_GunFlash is called.

Alright.. I think I've done 1 thing right, when the gun is fired, it lowers down, but never goes back up.

Code: Select all • Expand view

  Fire:
    SHTG A 3
    SHTG A 7 A_FireShotgun
    SHTF A 0 Bright A_SetPitch (pitch-0.9)
    SHTF B 0 Bright A_SetPitch (pitch+3.0)
    SHTG BC 5
    SHTG D 4
    SHTG CB 5
    SHTG A 3
    SHTG A 7 A_ReFire
    Goto Ready

That's because A_SetPitch happens instantly, and you're having two of them happen in a row with no duration between them. Perhaps this:

Code: Select all • Expand view

Fire:
    SHTG A 3
    SHTG A 7 A_FireShotgun
    SHTF A 0 Bright A_SetPitch (pitch-0.9)
    SHTG B 2
    SHTF B 0 Bright A_SetPitch (pitch+3.0)
    SHTG B 3
    SHTG C 5
[...]

Granted, there are a lot of things I would be doing here involving abusing Offsets and smoothing the SetPitches into 1-tic states instead, but I've restrained myself from doing that here. =P

How do I make an actor immovable (GZDoom)?

Setting the mass to 0x7FFFFFFF makes the actor immovable for most intents and purposes.

Unfortunately not to A_FPunchAttack it seems, which is used by the Fighter's weapons (except Quietus). Since I was using the Fighter, the immovable actors were being moved about when I hit them regardless of their mass.

Is there anyway for an enemy to be attacking while moving?

ThrustThing? The example shows how to thrust based on current actor angle.

I have this idea for an open world Metroidvania style WAD with toggle-able inventory items that act as the various upgrades to the player, including allowing the player to double-jump, doubling the player's jump height, and giving the player the ability to sprint (by default, running speed would be set the same as walking) and, in effect, jump farther. Could anyone give me some tips on how to code these upgrades/inventory items?

Is there a way to create a custom melee attack with a custom damage type? The closest thing I found was A_CustomMeleeAttack, but it doesn't work with player weapons.

From decorate you should use A_ChangeVelocity; this "native" decorate function offers max precision on angle without requiring explicit recalculation from decorate, and lets you use or ignore the calling actor's angle (as well as its current momentum). This is the right answer if you want the enemy to start a motion that will continue for a few ticks, but it might not be perfect for your purposes. Another approach would be to make additional movement frames in the attack state, using monster-movement functions (A_Wander, A_Chase). However, I don't think you have enough control over those to achieve the effect you desire.

Use A_Punch or A_Saw (depending on what you need), and set the damage type on a custom bullet puff.

I use A_CustomPunch.

[Vaecrius]

A_Wander or A_Chase with null attack states should be able to get movement into an attack sequence.

My questions:

1. Is there any way for an actor to access its master's inventory?

2. How do I edit the boss brain explosions? Replacing the BrainExplode state does nothing.
EDIT: Answer: Can't, blame Dehacked.
