turns out i lied :p GatewayEntity class has a nifty function called summonerOrClosest(), which fits my script perfectly, only problem is, i have no idea how to properly invoke functions from a java class in KJS

class function in reference: https://github.com/Shadows-of-Fire/GatewaysToEternity/blob/9b1df9781750be124009044127c03c96d3615fa3/src/main/java/shadows/gateways/entity/GatewayEntity.java#L222

let $gatewayEntity = java('shadows.gateways.entity.GatewayEntity$summonerOrClosest')

onForgeEvent('shadows.gateways.event.GateEvent$Failed', event => {
    console.log(event.entity.getGateway().getId())
    console.log(event.entity.getGateway()[$gatewayEntity])
    //let summoner = event.entity.getGateway()['$gatewayEntity$summonerOrClosest']
})```
this is where i'm at right now, it just crashes on startup claiming syntax errors, and it's right :p

i guess converting the PlayerEntity into PlayerEntityJS would also be an important detail that needs to be done

#

lets play the game where you actually give the context of what you want to accomplish 😄

urban fog Jun 2, 2023, 9:18 PM

#

when a gate is failed, give back a gateway pearl of the failed gate

keen bough Jun 2, 2023, 9:18 PM

#

makes sense

#

so you don't need that weird import

urban fog Jun 2, 2023, 9:20 PM

#

i could probably also just pop the pearl item at the gate position, that would be a fitting alternative

keen bough Jun 2, 2023, 9:20 PM

#

event.getEntity() gives you a GatewayEntity so you'd just
event.getEntity().summonOrClosest()

urban fog Jun 2, 2023, 9:20 PM

#

oh, it's that easy?

#

pff

keen bough Jun 2, 2023, 9:21 PM

#

anything you see in that gatewayentity class, that isn't private of course, can be run on the object you get back in that event from the entity

urban fog Jun 2, 2023, 9:21 PM

#

alright, that's useful info

#

keen bough Jun 2, 2023, 9:24 PM

#

show your work?

urban fog Jun 2, 2023, 9:24 PM

#

that's a different classpath than where i was looking

#

hm

keen bough Jun 2, 2023, 9:24 PM

#

event.entity is the GatewayEntity, not event.entity.getGateway()

urban fog Jun 2, 2023, 9:24 PM

#

onForgeEvent('shadows.gateways.event.GateEvent$Failed', event => {
    console.log(event.entity.getGateway().getId())
    console.log(event.entity.getGateway().summonerOrClosest())
    //let summoner = event.entity.getGateway()['$gatewayEntity$']
})```

bad dog

urban fog Jun 2, 2023, 9:25 PM

#

oh so i just cut getgateway

#

derp

#

i can read code, usually

keen bough Jun 2, 2023, 9:26 PM

#

heh

urban fog Jun 2, 2023, 9:26 PM

#

ok cool

urban fog Jun 2, 2023, 9:42 PM

#

alright, so i want to have a failsafe incase no players are found to just drop the item on the ground at the gate's position, but uh, quarter of an idea how to do that

#

tried copying homework™️ from tazz's entitySnipSnip, but things aren't the same on 1.16, problem calling createEntity() on undefined

#

onForgeEvent('shadows.gateways.event.GateEvent$Failed', event => {
    let gateID = event.entity.getGateway().getId()
    let summoner = event.entity.summonerOrClosest()
    let pearlOfGate = Item.of('gateways:gateway_pearl', `{gateway: ${gateID}}`)

    if(summoner.name){
        summoner.give(pearlOfGate)
    } else {
        let {x, y, z} = event.entity
        let pearlItemEntity = event.entity.world.createEntity('minecraft:item')
        pearlItemEntity.x = x
        pearlItemEntity.y = y
        pearlItemEntity.z = z
        pearlItemEntity.item = pearlOfGate
        pearlItemEntity.item.count = 1
        pearlItemEntity.spawn()
    }
})```

keen bough Jun 2, 2023, 9:51 PM

#

event.entity.world.asKJS().createEntity('minecraft:item')

#

you can use .asKJS() on an entity, server, or world to wrap them in the kubejs version

urban fog Jun 2, 2023, 9:53 PM

#

dev.latvian.mods.rhino.EcmaError: TypeError: Cannot call method "asKJS" of undefined (startup_scripts:return_gate_summon.js#10)

#

let pearlItemEntity = event.entity.world.asKJS().createEntity('minecraft:item')

#

wat da hel

keen bough Jun 2, 2023, 9:55 PM

#

sure it's not level instead of world? I think that changed mid 16

urban fog Jun 2, 2023, 9:57 PM

#

i've another script in the same instance using event.world

#

so i'd think not

#

i'll give it a whirl though

#

crashed faster, so uh, probably not

#

same error though, just a final tick on the gateway entity

keen bough Jun 2, 2023, 9:59 PM

#

can always move it up, try event.entity.asKJS().world.create

urban fog Jun 2, 2023, 10:02 PM

#

dev.latvian.mods.rhino.EvaluatorException: Cannot convert dev.latvian.mods.rhino.Undefined@0 to double (startup_scripts:return_gate_summon.js#11)

#

well uh, new error

#

so i guess that means it's working lol

#

think i got an idea for this though, event.entity.asKJS() for the xyz

#

yeah, seems to have done it

#

didn't crash

#

well, didn't crash when it expired, but didn't log anything

#

nevermind, that's expected with the current code

#

didn't get it back though, hm

keen bough Jun 2, 2023, 10:14 PM

#

add logging everywhere, that's what I do lol

#

you should do the function trick so you don't have to keep restarting mc though, will make things faster

urban fog Jun 2, 2023, 10:15 PM

#

o

#

wut function trick

#

have a function outside the event and invoke it within?

keen bough Jun 2, 2023, 10:16 PM

#

si

#

can't reload events, but functions will

urban fog Jun 2, 2023, 10:16 PM

#

mmm

keen bough Jun 2, 2023, 10:17 PM

#

onForgeEvent('shadows.gateways.event.GateEvent$Failed', event => {
  global.GateFailed(event)
})

global.GateFailed = (event) => { 
    let gateID = event.entity.getGateway().getId()
    let summoner = event.entity.summonerOrClosest()
    let pearlOfGate = Item.of('gateways:gateway_pearl', `{gateway: ${gateID}}`)

    if(summoner.name){
        summoner.give(pearlOfGate)
    } else {
        let {x, y, z} = event.entity
        let pearlItemEntity = event.entity.world.createEntity('minecraft:item')
        pearlItemEntity.x = x
        pearlItemEntity.y = y
        pearlItemEntity.z = z
        pearlItemEntity.item = pearlOfGate
        pearlItemEntity.item.count = 1
        pearlItemEntity.spawn()
    }
}

#

now you just pop a nice /kubejs reload startup_scripts and voila

urban fog Jun 2, 2023, 10:18 PM

#

mmm

#

tasty

keen bough Jun 2, 2023, 10:19 PM

#

probably just need to convert the player to a kjs or the itemstack to mc

urban fog Jun 2, 2023, 10:19 PM

#

nothing is logged thonk

#

do i need to /reload too?

keen bough Jun 2, 2023, 10:19 PM

#

well you still have to do the initial mc restart yea?

urban fog Jun 2, 2023, 10:19 PM

#

oh

#

maxint iq

keen bough Jun 2, 2023, 10:19 PM

#

because the event still doesn't reload

#

hehe

#

yeah you need to do summoner.asKJS().give(pearlOfGate) I'm pretty sure

urban fog Jun 2, 2023, 10:23 PM

#

yay no crash

#

the pearl is being logged as Item.empty though thonk

#

that doesn't bode well

#

~~maybe i should put this on a different gate event for the time being so i don't have to wait 45 seconds to see if it makes the game explode~~

#

alright, it seems like .asKJS() on the summoner makes it print my name instead of undefined, but the pearl is still Item.empty

keen bough Jun 2, 2023, 10:29 PM

#

try

let pearlOfGate = Item.of('gateways:gateway_pearl', `{gateway: "${gateID.toString()}"}`)

#

make sure you get the " in there too

urban fog Jun 2, 2023, 10:30 PM

#

you know, that uh, might have helped

#

hm, no dice

#

it is trying to give me the item though, so it's doing good there

#

also, a string of '' is considered false in JS, yeah?

#

pfff

#

found the problem

#

gateways:gate_pearl, not gateways:gateway_pearl

#

works perfectly now

keen bough Jun 2, 2023, 10:50 PM

#

huzzah!

urban fog Jun 2, 2023, 10:55 PM

#

agh, what's the array contains object function in JS, i swear i'm either never using it or always forgetting

keen bough Jun 2, 2023, 10:56 PM

#

includes?

urban fog Jun 2, 2023, 10:56 PM

#

    console.log(global.gatewayRefundBlacklist.includes(gateID))
    if(global.gatewayRefundBlacklist.includes(gateID)) return```
```[15:56:45] [INFO ] gateways:blaze_gate_small
[15:56:45] [INFO ] Emmerdog
[15:56:45] [INFO ] Item.of('gateways:gate_pearl', '{gateway:"gateways:blaze_gate_small"}')
[15:56:45] [INFO ] false
[15:56:45] [INFO ] Refunded Gate Pearl of "gateways:blaze_gate_small" to player "Emmerdog"```

#

    'gateways:blaze_gate_small'
]```

keen bough Jun 2, 2023, 10:59 PM

#

gateID itself is a ResourceLocation, hence why I added the 'toString()' in my example of the item.of

#

rhino should cast it to a string I'd think to test the includes, but not sure

urban fog Jun 2, 2023, 11:00 PM

#

applying .toString() didn't seem to give different results

#

and it's not that way in the pearlOfGate variable

urban fog Jun 2, 2023, 11:43 PM

#

still confused on this stuf

molten crypt Jun 3, 2023, 1:44 AM

#

keen bough rhino should cast it to a string I'd think to test the includes, but not sure

this is 1.16 so probably not
tho i cant remember the exact version lat added it

urban fog Jun 3, 2023, 8:53 PM

#

alright, so i got back on this, and if i .push() the gateID to the blacklist object, it works as it should on the next attempt, but .typeOf claims both are undefined
