The "How do I..." Thread

[BlueFireZ88]

Thanks Blue Shadow.

And Zombieguy:

I've seen a few wads that implement those kind of features with seperate Actors.

A few examples I can name:
Z86's Particle Enhancement Wad
Beautiful Doom
Brutal Doom

It should have the coding you need to refer to to give you an idea on how those actors are constructed.

[Zombieguy]

Thanks, man. I found the coding for the wall-chunks in Brutal Doom. Now, for those fancy bullet effects.

[Zombieguy]

Does anyone know how to add a custom ricochet sound on death state/xdeath state for bullet puffs?

[Enjay]

The wiki page for them actually tells you which sounds it will play for which events.

[wiki]Classes:BulletPuff[/wiki]

Personally, I prefer redefining the actor and playing a sound in the appropriate state using a code pointer to play the sound but the built in system works well enough.

[Zombieguy]

Thanks, Enjay. I have another question:
When I spawn in the first map while loading my custom pk3 file, in the upper left corner, it says: "p_startscript: unknown script 292" and then fades away. It's not a big deal, but it's annoying. How do I fix this?

[Blue Shadow]

That means that the engine is trying to run a script that doesn't exist, which in this case it's script #292.

[Enjay]

Yes, so presumably you have a decorate item or another script or a line or something set to run that script. ZDoom is receiving the instruction but the script does not exist in the BEHAVIOR for the level so you get the error message. So, you will have to track down what is trying to run the script and fix that.

[Zombieguy]

Enjay, you, are a DECORATE god.

[Enjay]

No, I have just learned a few tricks from those who are.

[Zombieguy]

I have an issue. The BulletPuff plays its sound, except for its XDeath state sound. And the SawPuff, dosn't play its sound, it just plays the BulletPuff's ricochet sound. And the FistPuff doesn't play any sound at all. Any help on how to add custom BulletPuff sounds, and get the BulletPuff to enter its XDeath state? Code -

Put an empty, 0-tic frame at the beginning of every state.

The engine never processes functions in the first frame of an actor's existence.

Note: Despite what the Wiki implies, new puff actors do not have to inherit from BulletPuff.

[Zombieguy]

Could you give me an example of the 0-tic frame trick, please?

[NeuralStunner]

TNT1 A 0

That's all.

... By the way, do NOT use "NULL". TNT1 is there for exactly that purpose.

[Zombieguy]

Put an empty, 0-tic frame at the beginning of every state.

Wait, at the beginning of which states? I put a 0-tic frame on every line, and it didn't work.

EDIT: Why don't you just take my code I posted, and show me exactly how you want me to do it? Just to make it easier.

Just the one actor, but it should give the right idea.
