Clock Rocket Flare providing vision of invisible units | ModDota | Page 1

#

Basically I want to make an item where I cast an aoe spell that reveals an area, I got that part down but I don't know how to proceed when it comes to making so that it also reveals invisible units

#

#

here's the code I have so far

#

(btw clock's sound isn't working for some reason)

fresh pumice May 15, 2024, 12:52 AM

#

try
find units in radius and
target:AddNewModifier(caster, self, "modifier_truesight", {duration = sight_duration})

crude oriole May 15, 2024, 12:58 AM

#

I want the invisible units to be displayed inside of the area, but if they leave they get hidden again

#

instead of it "revealing them" even after they leave the area

#

if they get hit initially

#

I'm assuming it's gonna work like that, so I'll try it out, thank you

smoky hearth May 15, 2024, 1:03 AM

#

crude oriole I want the invisible units to be displayed inside of the area, but if they leave...

put a dummy unit in the center that has a modifier that emits an aura of modifier_truesight

#

thats how valve handles that kind of thing

crude oriole May 15, 2024, 1:04 AM

#

hm so I guess it's more complex than I initially thought

#

do you have any examples of dummies being created?

wind gateBOT May 15, 2024, 1:04 AM

#

Found 1 function for createmodifierthinker

🇸 CreateModifierThinker(caster: CDOTA_BaseNPC|nil, ability: CDOTABaseAbility|nil, modifierName: string, paramTable: table|nil, origin: Vector, teamNumber: DOTATeam_t, phantomBlocker: bool): CDOTA_BaseNPC
Create a modifier not associated with an NPC.

smoky hearth May 15, 2024, 1:04 AM

#

just use that

#

if you open that link, and click the github button you'll see plenty of examples

crude oriole May 15, 2024, 1:05 AM

#

thanks

smoky hearth May 15, 2024, 1:06 AM

#

it says >not associated with an NPC.
but in reality there is a dummy unit that the modifier applies to

crude oriole May 15, 2024, 1:06 AM

#

is a dummy unit invisible?

smoky hearth May 15, 2024, 1:07 AM

#

yes, the unit from createmodifierthinker has ~~no model~~ invisible box model and is not found by things like findunitsinradius normally

#

you can find them if you want to, but in 99% of cases you dont want to

crude oriole May 15, 2024, 1:10 AM

#

what would be the best way to get the enemy's team team number

#

#

this is what I have currently

smoky hearth May 15, 2024, 1:12 AM

#

it would be the team number of the caster

#

the true sight would reveal all of the enemies of the casters team

crude oriole May 15, 2024, 1:13 AM

#

oh

smoky hearth May 15, 2024, 1:15 AM

#

crude oriole

hold on. you need to make your own modifier to apply to the thinker

#

and that modifier emits an aura of modifier_truesight

crude oriole May 15, 2024, 1:15 AM

#

ah I thought a thinker would be special in the sense that you just apply any modifier to it and it works

#

I see

smoky hearth May 15, 2024, 1:18 AM

#

there are a bunch of modifier functions for auras.
you would need most of them

wind gateBOT May 15, 2024, 1:18 AM

#

Found 11 functions for aura

🇸 🇨 CDOTA_Buff:GetAuraDuration(): float
Returns aura stickiness (default 0.5).
🇸 🇨 CDOTA_Modifier_Lua:GetAuraDuration(): float
Returns aura stickiness.
🇸 🇨 CDOTA_Modifier_Lua:GetAuraEntityReject(entity: CDOTA_BaseNPC): bool
Return true/false if this entity should receive the aura under specific conditions.
🇸 🇨 CDOTA_Buff:GetAuraOwner(): CDOTA_BaseNPC|nil
Returns the owner of the aura modifier, that applied this modifier. Always `nil` on the client.
🇸 🇨 CDOTA_Modifier_Lua:GetAuraRadius(): int
Return the range around the parent this aura tries to apply its buff.
and 6 more…

crude oriole May 15, 2024, 1:19 AM

#

yeye

#

I think I know how to make that one

smoky hearth May 15, 2024, 1:19 AM

#

alright

#

do note that you should use DOTA_UNIT_TARGET_FLAG_INVULNERABLE, so that the true sight is applied to invulnerable units.

#

by default invulnerable units are ignored in searches and such

crude oriole May 15, 2024, 1:24 AM

#

#

worked beautifully

#

what would be an invulnerable unit?

#

like an example

#

bkb?

#

#

something like this right

smoky hearth May 15, 2024, 1:26 AM

#

yeah

smoky hearth May 15, 2024, 1:26 AM

#

crude oriole what would be an invulnerable unit?

euls scepter, faceless void's time walk, banes nightmare

#

plenty of others

crude oriole May 15, 2024, 1:43 AM

#

#

why is the sound not working

#

and particle

#

I dont get it

reef lava May 15, 2024, 1:53 AM

#

did you precache them?

#

if you don't tell the engine to load them then you can't use them

#

some don't need to be loaded, but generally anything thats tied to a hero or other entity needs to be

crude oriole May 15, 2024, 1:56 AM

#

oh

#

so this is why the cheese sound effect works

#

but this one doesnt

#

I see

reef lava May 15, 2024, 1:56 AM

#

yep

crude oriole May 15, 2024, 1:56 AM

#

where do I precache

#

npc items custom?

reef lava May 15, 2024, 1:56 AM

#

either in the ability kv, in the ability lua, or in addon_game_mode.lua

#

I generally use the ability lua

#

function kraken_spout:Precache( context )
    PrecacheResource( "soundfile", "soundevents/game_sounds_heroes/game_sounds_tidehunter.vsndevts", context )
    PrecacheResource( "particle", "particles/units/heroes/hero_tidehunter/tidehunter_gush.vpcf", context )
    PrecacheResource( "particle", "particles/units/heroes/hero_tidehunter/tidehunter_gush_splash.vpcf", context )
    PrecacheResource( "particle", "particles/units/heroes/hero_tidehunter/tidehunter_gush_slow.vpcf", context )
end

#

I think elfansoer used to precache in the KV, but he does it in the lua now, you can see in the repo that old abilities have the precache in the kv

#

https://github.com/Elfansoer/dota-2-lua-abilities/blob/master/scripts/vscripts/lua_abilities/abaddon_mist_coil_lua/abaddon_mist_coil_lua.txt

#

"precache"
        {
            "soundfile"    "soundevents/game_sounds_heroes/game_sounds_abaddon.vsndevts"
            "particle"    "particles/units/heroes/hero_abaddon/abaddon_death_coil.vpcf"
        }

crude oriole May 15, 2024, 2:14 AM

#

#

still doesnt work

#

I'm confused

#

is there a chance this isnt working because clockwork is disabled?

#

on the herolist

#

actually no that doesnt make sense because shadowfiend is disabled and I can use its autoattack as a particle

crude oriole May 15, 2024, 2:46 AM

#

followup question is there any good examples of repos messing with panorama after the change so that the <scripts> tag isn't allowed?

smoky hearth May 15, 2024, 2:50 AM

#

crude oriole followup question is there any good examples of repos messing with panorama afte...

What do you mean scripts tag isnt allowed?

#

And "messing with panorama" is pretty vague.

crude oriole May 15, 2024, 2:54 AM

#

smoky hearth May 15, 2024, 3:05 AM

#

Well that says, <script> is not allowed in custom_ui_manifest.
You can still use it in other xml's, and there is both <script> and <scripts>

#

Plural is for linking js files where the code would be.
Singular is for writing js code in the xml

crude oriole May 15, 2024, 3:09 AM

#

I see

crude oriole May 15, 2024, 3:09 AM

#

crude oriole

btw any explanation for this?

#

#

#

doth sound and particle dont work

#

if I change it to something like cheese or w/e it does work

smoky hearth May 15, 2024, 3:17 AM

#

Dotas items have all effects and sounds precached in every game because items are always in every game.
Hero/ unit stuff is not unless the hero is picked or you explicitly precache it.

Custom items are a little weird with precaching, it's been a long time so I'm not entirely sure but i think you need to call this in addon_game_mode's precache function in addition to that

wind gateBOT May 15, 2024, 3:17 AM

#

Found 2 functions for precacheitem

🇸 PrecacheItemByNameAsync(itemName: string, callback: (precacheId: int) → nil): nil
Asynchronously precaches a DOTA item by its dota_npc_items.txt name, provides a callback when it's finished.
🇸 PrecacheItemByNameSync(itemName: string, context: CScriptPrecacheContext): nil
Precaches a DOTA item by its dota_npc_items.txt name.

smoky hearth May 15, 2024, 3:19 AM

#

If that doesnt work then just precache the effects in addon_game_mode instead. As an item it always needs to be precached anyway

crude oriole May 15, 2024, 3:20 AM

#

I'll try

#

what's the difference between asynchronously and synchronously?

smoky hearth May 15, 2024, 3:25 AM

#

Sync is done immediately.
Async is done whenever there are spare resources.

#

Whenever possible you want to use async functions over sync, to prevent hiccups in the servers performance.
But in some cases you need sync

crude oriole May 15, 2024, 3:28 AM

#

even that doesnt work

#

I am so confused

#

#

also tried precacheitembynamesync and it didn't work

reef lava May 15, 2024, 6:18 AM

#

Ability precache is an ability method
Have a look at the first chunk of code I sent
I didnt know this was for an item, item precache is jankass so I always just put it into the addon_game_mode precache

sleek summit May 15, 2024, 12:02 PM

#

I'll also add that precaches on abilities occur when an ability is created. For heroes, that's usually great because heroes typically start with abilities and don't change them during the course of the game. There's usually just 1 of each ability in the game.

However, for items, which can be bought multiple times, it might be better to just precache the effect on addon_game_mode. This makes it so the precaches are done at the start of the game

like this?

#

I tried putting it on addon_game_mode

#

but it didnt work

#

this is why I found it weird

#

even precaching on the item lua doesnt work

#

am I really gonna have to pull the soundfile / particle separately and throw it into my mod

#

instead of getting it from dota itself

heavy dock May 15, 2024, 5:36 PM

#

Let's try another tricking way: create a rattletrap on map, then delete him

crude oriole May 15, 2024, 5:40 PM

#

I think I wanna figure the sound first

#

but I can try that as well

#

oh you mean on top of the createparticle function?

#

can I still create a rattletrap considering he's disabled on herolist?

#

maybe the particle I want doesn't exist? idk

#

but I checked it in the assets browser

smoky hearth May 15, 2024, 5:47 PM

#

crude oriole maybe the particle I want doesn't exist? idk

ok. surprised i didnt notice earlier but you're doing the sounds wrong.
not sure about the particle without checking the asset browser

#

you need to precache the sound events file for clockwerk (not individual sound files), and then play the sound thats listed there.

wind gateBOT May 15, 2024, 5:48 PM

#

Hero sounds

https://github.com/arcadia-redux/dota_vpk_updates/tree/main/soundevents/game_sounds_heroes

crude oriole May 15, 2024, 5:49 PM

#

I thought I just pulled the corresponding file

#

from whatever showed in assets browser

#

let me check

smoky hearth May 15, 2024, 5:50 PM

#

so for that sound effect the actual name you use in EmitSound is Hero_Rattletrap.Rocket_Flare.Explode

#

and the file you need to precache is game_sounds_rattletrap.vsndevts

crude oriole May 15, 2024, 5:50 PM

#

#

something like this?

smoky hearth May 15, 2024, 5:51 PM

#

yes

crude oriole May 15, 2024, 5:51 PM

#

do I put the folder as soundevents

#

or just gamesounds rattletrap

smoky hearth May 15, 2024, 5:51 PM

#

been too long, idk. gimmie a moment to find an example.

#

how you have it should be correct

crude oriole May 15, 2024, 5:53 PM

#

still doesnt work

#

gg

smoky hearth May 15, 2024, 5:54 PM

#

well now we're back to the issue of "items are jank at precaching" i think.
try putting the precache in addon_game_mode

#

and just to make sure. you are reloading the map after these changes, correct?

crude oriole May 15, 2024, 5:54 PM

#

lets see

#

yes

#

but I'm doing it through the console

#

instead of hammer

#

idk if that matters

smoky hearth May 15, 2024, 5:55 PM

#

no thats fine

crude oriole May 15, 2024, 5:55 PM

#

but I'm assuming not because all lua scripts update

#

OK IT WORKS

#

THE AUDIO AT LEAST

#

THANK GOD

smoky hearth May 15, 2024, 5:55 PM

#

great

crude oriole May 15, 2024, 5:55 PM

#

gonna remove it from the lua file

#

and keep it only on addon to see if it still works

#

it does ok

#

nice

#

what about the particle now

#

do I import it differently like in the game_sounds

smoky hearth May 15, 2024, 5:57 PM

#

no, the particle one is done how you have it (assuming the filepath is correct)

crude oriole May 15, 2024, 5:58 PM

#

#

hmmm

#

is it particle instead of particles

#

wait

#

oh it works now

#

ok now I just have to figure out

#

how to make the particle spawn at my cursor / point target

#

is it just pattach absorigin on target_position?

smoky hearth May 15, 2024, 6:05 PM

#

depends on the particle.
but the 'absorigin' pattachments are for attaching the particle to a unit.
if you just want it at a point in the world it probably be PATTACH_POINT

smoky hearth May 15, 2024, 6:08 PM

#

crude oriole how to make the particle spawn at my cursor / point target

most particles use cp0 as their "position" control point.
so you would want to set cp0 to the position

#

local particle_id = ParticleManager:CreateParticle(...)
ParticleManager:SetControlPoint(particle_id, 0, position)

something like that

crude oriole May 15, 2024, 7:46 PM

#

#

pattach_point isnt compatible with getcursorposition

#

what should I use instead?

smoky hearth May 15, 2024, 7:50 PM

#

crude oriole

in createparticle the last parameter is the unit the particle should be associated with, it can be nil.
its for things like fog of war hiding/showing the particle when the unit cant/can be seen for example.

#

you set the position with control points

crude oriole May 15, 2024, 7:51 PM

#

oh

#

I see

#

I tried with nil instead of caster as well

smoky hearth May 15, 2024, 7:54 PM

#

my bad

wind gateBOT May 15, 2024, 7:54 PM

what's the int value for

#

controlPoint: int

#

works perfectly now

#

smoky hearth May 15, 2024, 7:55 PM

#

particles can have any number of control points that influence their effects.
its different for every particle.
some have just cp0, some have like 15 of them.

beautiful

thank you

you can see if you open the particle in the particle editor what the cps do by changing their values.
clicking them also highlights what properties read them
