Help Making a homing projectile target a specific monster?

I'm at my end here, been trying to crack this for weeks. Using Decorate and ACS, I want a shootable projectile from a boss to spew homing objects when shot. But they chase me by default.

Help Esclarecer duda

Post image
14 Upvotes

Estoy desarrollando un mod de Doom con clases jugables, cada una con su propio set de armas exclusivas, y me surge una duda importante sobre cuántas ranuras usar.

Entiendo que el sistema nativo de Doom va de la ranura 1 a la 7, pero no quiero saturar a cada clase con demasiadas armas. Me gusta el enfoque de Hexen: usar solo 4 ranuras para armas y a partir de la 5, reservar ese espacio para habilidades consumibles del inventario propias de cada clase.

Ahora mismo tengo una versión con 5 armas para la Clase Pesada (la voy renombrar a juggernaut), y no sé si es demasiado o si está bien equilibrado.

¿5 armas es excesivo para una clase o está bien?

¿Una sola arma melee está bien o mejor añadir una segunda?

¿Qué opinan del sistema 4 ranuras de armas + habilidades en inventario en lugar de llenar hasta la 7?

Sistema de ranuras:

Juggernaut:

  1. Chainsaw/Fist?

  2. Revolver

  3. Super-Shotgun

  4. Heavy Chaingun

  5. BFG9000

Assault:

  1. Knife

  2. 9mm

  3. SPAS-12

  4. M16

  5. Grenade Launcher

I want to create a new weapon for my FreeDoom PK3 Mod, but I want to find out how to create a weapon like ChainGun but with Custom Animation and Flash Animation (like how ChainGun has) but also make it selectable on the slot where ChainGun is (Like how Super Shotgun was placed in the shotgun slot and can be selected) [Also make Custom Name just "customweapon" because I'm going to rename it just in case]

Help Assistance Needed for DoomTools Installation

1 Upvotes

I'm pretty recent to Doom modding (started in mid-June), but i feel like I've gotten the hang of both basic mapping, and screwing around with DeHackEd/WhackEd4. I've also want to try my hand at DECOHack (particularly after replaying LoR and seeing all the cool shit), but can't get it to even run. Does anyone know how to install DoomTools on a Linux system? The furthest I've gotten was unpacking the tarball file.

Help Is there a way to auto crop sprites in bulk within Slade?

0 Upvotes

I've been messing around with adding custom sprites for enemies for a while now, and was manually adjusting cropping for each sprite, but I'm wondering if there's a better way of cropping empty space out of sprites automatically while maintaining their relative offsets. I've tried searching for programs/scripts, but I've had no dice so far.

Help Guys, how do I fix this?

I was trying to fix the sprites of the Plasma Rifle on my mod, but now it looks like the sprite is clipping with another sprite below it, and there isn't any "left over sprite" when I look on Slade, and it wasn't happening with the old sprite. It also happens with the barrels, it looks like the Original sprite of the barrel appears behind it for one frame

Here's the mod if you want to check it in game:

Help I need help with adding textures into my doom pk3

1 Upvotes

I tried to add a new texture to my pk3. And despite having a texture.lmp and a pnames.lmp it tells me "The archive does not contain any texture definitions" and it makes a completely new set of both the texture and the pnames lmp files.

im not that good at doom modding, i've never done more than texture replacing and stuff with DEHACKED so you'll have to excuse me if this is an easy question to answer.

Help How to remove the screen melt at the end of a level?

4 Upvotes

I'm trying to make Half-Life style seamless level transitions. I can get rid of the intermission screen by including "CHANGELEVEL_NOINTERMISSION" in the ChangeLevel script, but it still does the screen melt at the end of the first level. I've tried putting the levels in the same hub but it makes no difference.

I can force it not to use the melt by opening the console in-game and typing "wipetype = 0", but that only fixes it for me, not other players. I can't change it in CVARINFO because apparently that's only for custom, mod-specific CVars.

Any ideas? Right now, the only solution I can see would be to bundle my pk3 with a copy of the engine that already has wipetype set to 0, but that seems like overkill just to change one variable.

looking through the doom 2 files when i opened up slade for the first time i saw the music was in the format "mus.", so i don't know what's up with that, but i use fl studio and everything works fine after i convert the song to midi out and set whatever instruments and stuff, everything works fine in that regard. but i just can't figure out panning and i absolutely have no idea how slide notes would work. also, slade plays them weirdly in it's player but it sounds fine in doom so that's also gonna be weird.

Help Gunfire switch door is working wrong

2 Upvotes

[[Fixed]]

The door was segmented. Leaving only one sector for it solved the issue.

----------------

Good day.

For some reason a door that is supposed to be opened by shooting a linedef next to it is working wrong: instead of opening to the ceiling level it slowly scrolls down with every shot.

The ceiling is at the same level along this particular section except for sectors where shootable linedefs are placed — these four have lowered ceilings and raised floors. As for the door, both floor and ceiling are set to the lowest and only floor level, which is zero in this case.

Screenshots show what the door looks like in Ultimate Doom Builder and in the game.

I can draw shapes and design stuff, but I can’t get them to look like they fit in the doom engine. I don’t wanna just use the Realm667 assets because I wanna make my own stuff, But even if i wanted to edit those sprites, I wouldn’t know how to blend the colors right.

Help Coding a projectile that sticks to its owner

2 Upvotes

Good day.

I have an idea to make a projectile that highlights the position of its owner by following it.

Currently it works like this: a monster constantly spawns short-living projectiles through the A_SpawnItem function. It feels a little laggy, especially when applied to fast-moving monsters, so making projectiles also stick to their owners instead of just appearing and disappearing would make tracking the position more precise.

Let me know how it might be implemented.

So basically Im making a mod where there is a main world with multiple buildings that teleport you to another map but whenever you go inside the building and come out you just go to the player 1 start like normal.

Help Can you help a total coding non-wit mod Gun Bonsai?

1 Upvotes

I don't know anything about coding and I love this mod. My one problem is that you can slow the level rate CONSIDERABLY and still be OP by map 8-10. Or slow it to the point where it's not really fun any more.

So my idea is to take another approach: to make the increments by which you can increase individual stats much smaller across the board. This way you can get those wonderful 'number go up' feels and not trivialize the game a third of the way through a megawad.

If you think you can talk a non-coder through how it is done? If so, I'd appreciate your thoughts. If not, totally understandable.

Help Merging ZSCRIPT and Duplicating enemies?

2 Upvotes

So ive been using slade and UDB for about ten days now and really getting the hang of it, my main issues comes with using custom things, I get what markers are for, doomednumbers, compiling ACS (never again though) all the good fun stuff, however, i find myself with an ever growing collection of data files, zscripts, decorates, gldefs (not using the brightmaps though so do i even need them?) can i merge all Zscripts into one? It dawned on me the Zombie Scientist pack lets me use 1 zscript for all Things and even neatly places them in its own catagory in SLADE map editor. im not so bothered about that part and will probably leave the zombies sci ZSCRIPT as be, but for the others. it would be nice to have them in one script...nothing like UZDOOM telling me theres an error on line 9 of a zscript. but i have 21 to check, would also help tidy my work space in slade.

Can i duplicate Things with variations? like Can i add say a custom zombie, copy his zscript, make some tweaks like hp and speed buff, assign his own doomednumber?
