How to make EntityJS Mob AI | latcord | Page 1

analog tendon Aug 15, 2024, 12:53 AM

#

I'm trying to make a custom slime mob using EntityJS, but even after looking through the wiki I have no idea how the AI creation works. I just want a mob that jumps to move, wanders around, and will attack the player. How would I go about doing such a thing?

#

it might be a bit daunting at first but after you understand the basics of goals you'll start to figure things out

#

Couple examples of adding goals to your entity js EntityJSEvents.addGoalSelectors("kubejs:wyrm", event => { // Enables the entity to walk around event.randomStroll(1, 0.3, 12, false) // Enables the entity to attack, essential for all other attack actions event.meleeAttack(2, 0.4, true) }) let Player = Java.loadClass('net.minecraft.world.entity.player.Player') EntityJSEvents.addGoals("kubejs:wyrm", event => { // Goal which enables the entity to fight back when hurt event.hurtByTarget(1, [], true, []) // Nearest Attackable Entity Goal event.nearestAttackableTarget(2, Player, 5, false, false, entity => { // Predicate of whether the entity can target the target, for example only let the adults attack return !entity.baby }) })

#

ofcourse if you're trying to replicate a slime goal where it jumps around you will have to create a custom goal with the event.customGoal method and take a look at the slime goals and replicate them by looking at the slime class near the bottom where the goals are

#

although i might add slime to the default builder list tomorrow as an option so you dont have to recreate the goals pepethink cause we currently have roughly 20-30 default mob builders and slimes arent one of them it looks like https://github.com/liopyu/EntityJS/wiki/Default-Minecraft-Entity-Builders

#

so if you want you can also wait for me to put out an update for that

analog tendon Aug 15, 2024, 1:54 PM

#

that would be amazing

#

thank you for the help!

mellow girder Aug 15, 2024, 6:43 PM

#

np! the new version should be up on curseforge/modrinth now which will allow you to do this js event.create("slime", "minecraft:slime")

#

im not sure if you already have a model or not but i also went ahead and used blockbench's Minecraft Entity Wizard to download and package the default slime texture/model, the animations are handled i believe by custom rendering though it should also be doable inside the entity builder with the .render() method

something like this should do it for the way they stretch when jumping around, basically mimicing the way vanilla does it in their own render method ```js
StartupEvents.registry("entity_type", event => {
event.create("slime", "minecraft:slime")
.scaleModelForRender(context => global.slimeRender(context));
});
/**
*

@param {Internal.ContextUtils$ScaleModelRenderContext<Internal.SlimeEntityJS>} context
*/
global.slimeRender = context => {
const { entity, poseStack } = context;
try {
let slime = entity;

 let size = slime.getSize();
 let partialTick = context.partialTick;
 let squish = slime.squish * 3;
 let prevSquish = slime.oSquish * 3;

 let lerpedSquish = (partialTick * (squish - prevSquish)) + prevSquish;
 let squishFactor = lerpedSquish / (size * 0.5 + 1.0);
 let inverseSquishFactor = 1.0 / (squishFactor + 1.0);

 // Scale the entity based on the squish factor
 poseStack.scale(inverseSquishFactor * size, 1.0 / inverseSquishFactor * size, inverseSquishFactor * size);
 poseStack.translate(0.0, 0.001, 0.0);  // Slight translation to avoid Z-fighting

} catch (error) {
console.log(error);
}
}```

thank you so much!! i was able to get it working using the new update

analog tendon Aug 15, 2024, 10:44 PM

#

mellow girder im not sure if you already have a model or not but i also went ahead and used bl...

i do already have a custom model and i was able to get it working

#

also, would it be possible for me to change the texture of the particles when it lands?

#

it's currently just using the default slime particles, but i want to make blue particles to go with the color of the mob

mellow girder Aug 15, 2024, 10:54 PM

#

analog tendon also, would it be possible for me to change the texture of the particles when it...

.setParticleType("crit")```

#

you also have the js .setSquishSound("block.azalea.hit")

#

for example

analog tendon Aug 15, 2024, 11:04 PM

#

thank you again!!

#

my only other problems are i can't get it to attack me or to drop anything

#

it tries jumping towards me, but it does no damage

mellow girder Aug 16, 2024, 12:26 AM

#

hmmm

#

why does it do damage to other mobs like iron golems but not the player

#

i mightve figured out why, gimme a bit

mellow girder Aug 16, 2024, 12:46 AM

#

analog tendon it tries jumping towards me, but it does no damage

alright so this seems to be lack of implimentation on my end where playertouch isnt calling the super method by default so you'll have to for now do this js .playerTouch(context => { let { entity, player } = context if (entity.isDealsDamage()) { entity.dealDamage(player) } })

analog tendon Aug 16, 2024, 12:48 AM

#

alright

#

is there a way to control how much damage it deals for each slime size?

mellow girder Aug 16, 2024, 12:53 AM

#

yea

#

it does this automatically but you can effectively overwrite it with the js .onAddedToWorld(entity => { entity.modifyAttribute("minecraft:generic.attack_damage", "uniqueid", 5, "addition") }) method

#

you get the size with entity.size

analog tendon Aug 16, 2024, 12:55 AM

#

alr, will test it now

#

also i don't know if i'm doing something wrong, but even with the the playerTouch, im not taking damage from the slimes

mellow girder it does this automatically but you can effectively overwrite it with the ```js ....

when the entity spawns, the health isn't set to its max health. so the slime will show up with 16 max health, but only spawn on 1 health.
is there a way to change the starting health to be the same as its max health?

#

ahh ok

#

i was confused, ok so whats happening is you're setting the attribute to 16 for every one regardless of size? @analog tendon

analog tendon Aug 16, 2024, 11:27 PM

#

yes, but i also tried setting the attribute for each size as well, and while the attributes would still set correctly, the starting health would still be wrong

#

so both ways didnt work properly for me

mellow girder Aug 16, 2024, 11:28 PM

#

alright sec

#

uh

#

do you want the health to depend on size or do you want it to be constant

#

because there are 2 ways we can do this

analog tendon Aug 16, 2024, 11:29 PM

#

i want it to depend on size
either setting it manually per size, or just multiplying the default slime health by x amount for all sizes
both ways work for me

mellow girder Aug 16, 2024, 11:30 PM

#

alright

#

method 1:
when dealing with/modifying max health you'll need to heal the mob if the new value is greater than its default value js .onAddedToWorld(entity => { entity.modifyAttribute("minecraft:generic.max_health", "health_mb", 16, "multiply_base") entity.setHealth(entity.maxHealth) entity.modifyAttribute("minecraft:generic.attack_damage", "attack_mb", 2, "multiply_base") entity.modifyAttribute("minecraft:generic.attack_damage", "attack_a", 8, "addition") })
method 2:
you can also set the default values in the attribute modification startup event like so which will modify its health universally which will then get auto calculated by the default mobs health implimentation based on size, useful if you just want to make all the health values bigger or lowerjs EntityJSEvents.attributes(event => { event.modify('kubejs:dungeon_slime', attribute => { attribute.add("minecraft:generic.max_health", 16) }) })

#

also to detect what size they are you can do something like js switch (entity.size) { case 1: entity.modifyAttribute("minecraft:generic.attack_damage", "uniqueid", 5, "addition") break; case 2: entity.modifyAttribute("minecraft:generic.attack_damage", "uniqueid", 2, "addition") break; case 3: entity.modifyAttribute("minecraft:generic.attack_damage", "uniqueid", 1, "addition") break; default: entity.modifyAttribute("minecraft:generic.attack_damage", "uniqueid", 15, "addition") break; }

analog tendon Aug 16, 2024, 11:39 PM

#

i'm using method 1, and it works now!

#

also, is there a way to get them to drop items when killed?

#

as well as make the drops depend on the size

#

the slimes also just show up as entity.kubejs.dungeon_slime when looking at them using Jade, so is there a way to set the mob name?

mellow girder Aug 17, 2024, 12:18 AM

#

you can set the name with js .setCustomName("name") i believe

analog tendon Aug 17, 2024, 12:20 AM

it's giving an error for the custom name

hmm, one thing i think would be cool, but i don't know if it's too complicated, would be to make it so that the small slimes will try to merge together to make bigger slimes

but if that's too difficult then i can't think of anything else that needs to be done

i mean

also, is it possible to store a variable in an entity? so that way i could keep track of the slimes absorbed as something like entity.slimesAbsorbed and only have the slimes grow in size after a certain number have been absorbed

mellow girder Aug 17, 2024, 2:30 AM

#

sure, with persistent datajs entity.persistentData.MyVariable = 0

#

its basically an nbt tag

analog tendon Aug 17, 2024, 2:31 AM

mellow girder Aug 17, 2024, 2:31 AM

you can also store server perisistent data

server.persistentData

analog tendon Aug 17, 2024, 2:32 AM

so that would be a global variable not specific to the entity?

mellow girder Aug 17, 2024, 2:32 AM

#

yea

#

stored in the server itself

#

though for entity stuff its recommended to store it in the entity so its garbage collected when the entity disappears

server persistent data is for when you really need to store something static

mellow girder sure, with persistent data```js entity.persistentData.MyVariable = 0```

does this work for players too?

mellow girder Aug 17, 2024, 2:33 AM

#

yup

analog tendon Aug 17, 2024, 2:33 AM

#

amazing

mellow girder Aug 17, 2024, 2:33 AM

#

any entitys

analog tendon Aug 17, 2024, 2:33 AM

#

that is actually super helpful with something else i was stuck on

#

also...

#

📎 startup.log

willow relicBOT Aug 17, 2024, 2:34 AM

#

Paste version of startup.log from @analog tendon

analog tendon Aug 17, 2024, 2:34 AM

#

kubejs is having a stroke i believe

mellow girder Aug 17, 2024, 2:34 AM

#

oh uh

#

apparently setsize takes in a number and a boolean

#

replace what you have with ```js
.tick(entity => {
try {
if (entity.age % 20 != 0) return
if (entity.getSize() <= 1) {
let slimes = entity.level.getEntitiesWithin(entity.getBoundingBox().inflate(2))

                slimes.forEach(otherSlime => {
                    if (otherSlime.type != entity.type) return
                    if (otherSlime !== entity && otherSlime.size <= 1 && entity.getBoundingBox().intersects(otherSlime.getBoundingBox())) {
                        entity.setSize(entity.size + 1,true)
                        otherSlime.remove("discarded")
                    }
                });
            }
        } catch (error) {
            console.log(error)
        }
        
    })```

#

that try catch function will also prevent you from crashing anymore as well ™️

#

for most errors anyways

#

crap wait

#

i forgot to change out the grow

#

there

analog tendon Aug 17, 2024, 2:39 AM

#

i closed out of minecraft too quickly and my game had a stroke on the main menu when i relaunched

#

relaunching again seemed to fix it

#

and for the moment of truth

mellow girder Aug 17, 2024, 2:40 AM

#

did you copy the edited version of the script?

analog tendon Aug 17, 2024, 2:41 AM

#

mellow girder replace what you have with ```js .tick(entity => { try { ...

i copied this, then changed .grow(1.0) to .inflate(2), but i didn't copy it the second time if there were other changes

mellow girder Aug 17, 2024, 2:41 AM

#

dont think there were

#

did it work

analog tendon Aug 17, 2024, 2:42 AM

#

sort of

#

it only happens sometimes and they have to be really close

mellow girder Aug 17, 2024, 2:43 AM

#

increase the inflate

analog tendon Aug 17, 2024, 2:43 AM

#

alright

mellow girder Aug 17, 2024, 2:44 AM

#

its on a 1 second interval too for performance sake so if you want you could also change that around

#

that being this js if (entity.age % 20 != 0) return

analog tendon Aug 17, 2024, 2:45 AM

#

i was about to ask, how bad would the performance impact be if it was every tick instead of every 20?

mellow girder Aug 17, 2024, 2:46 AM

#

i mean probably negligible though its a good habit to have especially for things like this where you're dealing with bounding boxes, though it shouldnt be an issue since the bounding box is so small

#

if it were minecraft then they'd 100% do this without the 1 second interval check

#

so its up to you

#

well actually

#

theres this you could also do if you wanted js .onEntityCollision(ctx => { const {entity, target} = ctx })

#

though it'll only check if the entity is touching the other entity and wont be configurable to be lets say 1 block away

#

if you want them to combine 1 or 2 blocks away id stick with the tick method

analog tendon Aug 17, 2024, 2:50 AM

#

ill try the collision method and if the results are bad ill do tick

mellow girder Aug 17, 2024, 2:50 AM

#

sounds good

analog tendon Aug 17, 2024, 2:51 AM

#

        .onEntityCollision(ctx => {
            const {entity, target} = ctx
            if (entity.getSize() <= 1) {
                if (target.type != entity.type) return
                if (target !== entity && target.size <= 1 && entity.getBoundingBox().intersects(target.getBoundingBox())) {
                    entity.setSize(entity.size + 1,true)
                    target.remove("discarded")
                }
            }
        })

#

would this work

#

actually would the if statement even be needed

#

it wouldn't

mellow girder Aug 17, 2024, 2:53 AM

#

yeah id actually go the opposite to set a maximum standard tbh, like entity.getSize() <= 4 just so slimes cant create massive 50 sized slimes or something

analog tendon Aug 17, 2024, 2:53 AM

#


        .onEntityCollision(ctx => {
            const {entity, target} = ctx
            if (entity.getSize() <= 1) {
                if (target.type != entity.type) return
                entity.setSize(entity.size + 1,true)
                target.remove("discarded")
            }
        })

mellow girder Aug 17, 2024, 2:54 AM

#

that works

analog tendon Aug 17, 2024, 2:54 AM

#

nice

analog tendon Aug 17, 2024, 2:54 AM

#

mellow girder yeah id actually go the opposite to set a maximum standard tbh, like entity.getS...

i see nothing wrong with that :)

#

tho yeah a limit would probably be a good idea

mellow girder Aug 17, 2024, 2:54 AM

#

lol fair

#

im just saying if they're in spawners and someone makes a mob farm outta it

#

could cause lag

analog tendon Aug 17, 2024, 2:55 AM

#

what i might do is have a variable set when the slime first spawns for what its max size can be

#

nvm

#

the idea i had wouldn't work

#

i'll just set a limit to a size of 4 or 8

#

can i get an entity's health with entity.health?

mellow girder Aug 17, 2024, 2:58 AM

#

thats current health

analog tendon Aug 17, 2024, 2:59 AM

#

ok good

#

also

mellow girder Aug 17, 2024, 2:59 AM

#

wha

analog tendon Aug 17, 2024, 2:59 AM

#

did i put .onEntityCollision() in the wrong spot

#

or is it just being stupid

#

is probejs messing with me or is it grabbing the typings for the projectile builder

#

ok so apparently my typings are messed up because i didnt update

#

and i didnt impliment onEntityCollision for the other builders yet so just use this instead js .canCollideWith(ctx => { const {entity,collidingEntity} = ctx if (entity.getSize() <= 1) { if (collidingEntity.type == entity.type) { entity.setSize(entity.size + 1, true) collidingEntity.remove("discarded")} } return collidingEntity.canBeCollidedWith() && !entity.isPassengerOfSameVehicle(collidingEntity) })

#

here we have to return a boolean but its pretty much the super method

analog tendon Aug 17, 2024, 3:05 AM

#

testing now

mellow girder Aug 17, 2024, 3:05 AM

#

wait

#

there

#

now test

analog tendon Aug 17, 2024, 3:08 AM

#

didnt see the update until i had tested the earlier function lol

#

will retest

mellow girder Aug 17, 2024, 3:08 AM

#

i mean as long as you're returning a boolean it should be fine

analog tendon Aug 17, 2024, 3:08 AM

#

it did seem to work

mellow girder Aug 17, 2024, 3:08 AM

#

yeah

#

good

analog tendon Aug 17, 2024, 3:09 AM

#

the new version did an oopsie

#

but i did change something so ima unchange it

#

and see if it was my change or the code that crapped itself

mellow girder Aug 17, 2024, 3:10 AM

#

hold on

#

you could also use global functions like how we're doing with the render method so you dont have to keep restarting your game to refresh js .canCollideWith(ctx => global.collidefunction(ctx))

/**
 * 
 * @param {Internal.ContextUtils$CollidingEntityContext} ctx 
 * @returns 
 */
global.collidefunction = ctx => {
    const { entity, collidingEntity } = ctx
    if (entity.getSize() <= 1) {
        if (collidingEntity.type == entity.type) {
            entity.setSize(entity.size + 1, true)
            collidingEntity.remove("discarded")
        }
    }
    return collidingEntity.canBeCollidedWith() && !entity.isPassengerOfSameVehicle(collidingEntity)
}

#

this way instead you can do /kubejs reload startup_scripts to reload the global function

analog tendon Aug 17, 2024, 3:14 AM

#

alr

#

hmm

#

i want to change the script to this

global.collidefunction = ctx => {
    const { entity, collidingEntity } = ctx
    if (collidingEntity.getSize() <= 1) {
        if (collidingEntity.type == entity.type) {
            entity.setSize(entity.size + 1, true)
            collidingEntity.remove("discarded")
        }
    }
    return collidingEntity.canBeCollidedWith() && !entity.isPassengerOfSameVehicle(collidingEntity)
}

#

because right now the bigger slime disappears instead of the other way around

#

but when i change it to this

#

the game crashes

#

how could i make it so the small slime is absorbed into the big slime but the game doesnt crash?

#

also, something is wrong with one of my slimes

#

just that one though

mellow girder Aug 17, 2024, 4:57 AM

#

that looks like a case of client death desync, not an issue on entityjs' end

analog tendon Aug 17, 2024, 4:58 AM

#

yeah i figured the slime death thing wasn't too big a deal, thought i would mention it anyways tho

#

but do you have any idea what causes the game to crash when i change the script?

mellow girder Aug 17, 2024, 4:59 AM

#

always check your logs when it crashes

#

the error message tells you exactly what line is erroring and whats wrong

also

#

you didnt change the issue i will say that much

#

er wait a second

#

hmmm

#

it should be filtering out by entity type

#

so yeah nvm try it

#

i was seeing ghosts

analog tendon Aug 17, 2024, 5:06 AM

#

didn't work, have another idea

#

trying now

mellow girder Aug 17, 2024, 5:07 AM

#

also

#

you might want to put your code in a try catch and console.log(error) the output

#

to prevent crashes though i guess it should default catch anyways i just realized

analog tendon Aug 17, 2024, 5:08 AM

#

it works perfectly now

#

thank you so much

mellow girder Aug 17, 2024, 5:09 AM

#

awesome

analog tendon Aug 17, 2024, 5:11 AM

#

also, i hate to ask something else, but would it be possible to get the small slimes to pathfind to other slimes to merge?

#

since it currently only happens by chance

mellow girder Aug 17, 2024, 5:32 AM

#

with custom goals sure

#

https://github.com/liopyu/EntityJS/wiki/AI-Creation#:~:text=builder like so-,e.customGoal(,-'follow_target'%2C

#

right now the custom goal example on the wiki is making the mob pathfind towards a nearby player but you can change that to check if the nearby entity is instead of the same type/size ect just like youve been doing before

analog tendon Aug 17, 2024, 6:31 AM

#

i don't know if i can get it to work, but since it's not entirely nessecary i'll save that for later if i do it

#

anyways thank you so much for all of your help

#

i think i'll close the ticket now lol
