Adding a custom monster in dehacked

Recommended Posts

So I'm trying to add a new monster into my wad. It's an orange cacodemon that shoots arachnotron plasma (I'm using the cacolantern sprites). I'm replacing the SS nazi and I've already renamed the sprites to SSWV. I'll use pain elemental resurrection sprites or something like that for the attack sprites but for now I'm just trying to figure out how to get the sprites working like a regular orange cacodemon. So can someone finish defining the sprites so that what I have works like a regular cacodemon? And I'll be able to figure out how to change the attack later.

Here's a link to the wad: http://speedy.sh/YmuMb/resonance.zip

I'm going to answer your second question first, since a) it's harder; and b) I don't have time at the moment to download the WAD, so I can't see what you're doing with the sprites anyway.

You can't use the pain elemental resurrection frames for a new attack because they don't have code pointers (the things that tell the game what to actually "do" on each frame) and you can't add a code pointer to a frame that doesn't already have one (or remove a code pointer from one that does). In order to create a new attack, you need to replace frames that have code pointers. Since you're already replacing the SS guy, why not use his attack frames for the new attack? I've whipped up a DEH patch to demonstrate how it's done (warp to MAP31 or MAP32 to see the new monster in action).

Doom version = 20
Patch format = 6


Thing 24 (Cacotron)
#I'm using the original cacodemon frames here, just to demonstrate the new attack
Initial frame = 502
Hit points = 400
First moving frame = 503
Alert sound = 42
Injury frame = 507
Pain chance = 128

Death sound = 65
Width = 2031616
Mass = 400
Action sound = 77
Bits = 4211206
Respawn frame = 516

#These frames replace the SS guy's frames to use the original cacodemon attack sprites; if you've already replaced the original SS guy sprites, change the sprite numbers to 51 (SS guy)
#Change the Duration of these frames to change the rate of fire (lower = faster)

Frame 736
Sprite number = 40
Sprite subnumber = 32770
Duration = 3

Frame 737
Sprite number = 40
Sprite subnumber = 32771
Duration = 4

Frame 738
Sprite number = 40
Sprite subnumber = 32770
Duration = 1
Next frame = 736

#Now to change the code pointers for the attacks frames, to replace the SS guy's attack with the arachnotron attack
#There is no need to change the code pointer for Frame 736, since the original one (which makes monsters aim at you before attacking) is what we want anyway

#This code pointer is from the arachnotron attack frames, and is the one that shoots the actual plasma ball
Pointer 414 (Frame 737)
Codep Frame = 648

#This code pointer is from the spider mastermind attack frames and reused for the arachnotron, as makes the monster stop shooting and start chasing you again if you break the line of sight (I think? Whatever, it works anyway)
Pointer 415 (Frame 738)
Codep Frame = 618

Oh yeah and I also forgot to mention that I am working in limit removing compatibility, NOT vanilla. So I don't have the same restrictions. Look at the green cacodemon, I used some of the pain elemental resurrection sprites to do his attack. Although you may be right about me not having to do that again with the orange cacodemon. Also I'd like the cacodemon to just shoot 5 arachnotron plasma cells and then go back to chase.

Oh yeah, another good reason to not reuse the resurrection sprites is that pain elementals can in fact be resurrected, if its corpse is crushed before it finishes exploding.

Done.

The pain elemental actually being resurrected is one of the rarest phenomena in all of the doom universe. I only saw it happen for the first time in my life just recently.

The cacotron seems to be working, except that it's not using the orange cacolantern sprites I provided. How do I change that?

I still haven't seen your WAD, but assuming your SSWV* sprites correspond exactly with HEAD* sprites, this works:

You'll notice that the Cacotron now replaces the Green Armor, and the Green Armor replaces the SS guy (in the Thing table, not the Frame table; Cacotron still uses SS guy frames). This is because I just realised that if you replace an SS guy with another enemy, it'll still drop a clip when killed, and there is no way around this. The Cacotron still has the same Map ID as the SS guy, and the Armor still has its original Map ID, so from a mapping perspective everything is the same, the only difference is that Armor now drops clips when killed (a non-issue because Armor can't be killed).

Aside from that, all I've done is change the Sprite subnumbers and Next frames to match the cacodemon's animation (and changed the thing to use these frames).

Aha! Now it works. I didn't have the sprites correspond to the HEAD sprites at first, so I renamed them and it seems to work now without conflicting with any of my other stuff, just have to test it a little more to be 100% sure.

hahaha that'd be funny: an armor monster that drops clips.

I only see one minor issue: The death and attack sequences look like they are skipping a sprite. Like for the attack, it looks like the cacotron is opening its mouth too quickly and without the first mouth opening sprite, and for the death frame it just looks too quick. They're both pretty small issues though, or it could just be me.

EDIT: just found that the resurrection frames look weird

Oops. You're right, I skipped a frame on the attack animation. And I forgot to change the duration on the death/resurrection frames. This should work perfectly now:

For editing DeHackEd patches it's probably no easier than using Notepad, unless Gez snuck something in I haven't noticed.
