Key cards no longer working when using inheritance?

[Doomsday]

I think that's what it's called atleast. I've just been trying to make Key cards make a pick up sound and for some reason I won't be able use them on doors. Atleast keys that are in the map, the keys that go into my inventory when I use give all work however.

If all you want is to change the general key pickup sound, the simplest way is to include the new sound in the PWAD (for example KEYUP), then add SNDINFO lump with the line:

misc/k_pkup      KEYUP

This way it replaces the existing pickup sound for keys.

 

If you want to create completely new keys, you need to make a Key actor (inheriting from Key class) and then add a LOCKDEFS lump with the appropriate lock definition (determining, for example, what key is required to open it). You will assign a number for the lock, which you can set on a line action in the editor.

 

Here's a key template (the standard blue keycard) you can refer to when making your custom key:

Here's the reference for LOCKDEFS (with examples):

And here's a list of used lock numbers (so pick one that is not one of them and in between 1 and 255):

Keys are tricky because they are connected to other lumps, namely LOCKDEFS. Redefining a key also implies redefining the locks with the new key name.

Possibly my tutorial can help you

I never actually noticed that there was a pick up sound for keys already in DOOM. I was hoping to have a seperate sound for skulls but this will have to do.

You can make actors to replace the existing keys and determine the pickup sounds for each however you want.

 

Here's an example for a yellow key and yellow skull replacements where the only thing that is changed is the sound:

Actor YellowCardAlt : YellowCard replaces YellowCard
{
	Inventory.PickupSound "keycard/pickup"
}

Actor YellowSkullAlt : YellowSkull replaces YellowSkull
{
	Inventory.PickupSound "skullkey/pickup"
}

To make these work, load your pickup sounds into your wad/pk3 (let's say they're called SKEYUP and CKEYUP) and then add to the SNDINFO

keycard/pickup     CKEYUP
skullkey/pickup    SKEYUP

Apparently, it's now possible to define new keys that can open existing locks without the need of LOCKDEFS! You just have to set its Species property to an existing key actor, and it will open the same kinds of doors as that one.
