How do I raycast?

[grand vapor]

I asked this in a different way ealier because I didnt know what it was called. I need the raycast to detect if the player is looking at an entity. Should I do commands or script?

I know it can be done with command blocks, but is there an easy way to do it with a script?

[woeful pollen]

player.getEntitiesFromViewDirection()

[grand vapor]

Do I do a returndata or something?

[woeful pollen]

what

[grand vapor]

Sorry, im new to scripting. Ive been doing command blocks for a long time, but not this. How do I get the entity type that the player is looking at

world.getAllPlayers().forEach((player) => { if (player.hasTag("Player")) { player.getEntitiesFromViewDirection() }

That is what I have, but it does nothing yet

[woeful pollen]

you need to use system.runInterval, you will need to use a for loop to loop through all players

[grand vapor]

I have that

[woeful pollen]

forEach

okay, that works too

[grand vapor]

But how do I make it return the type of entity that the player is looking at?

[woeful pollen]

this returns an array too, so you could use forEach for the entities aswell.

or you could just index it, by getting the first entity in the array.
player.getEntitiesFromViewDirection()[0]

[grand vapor]

I see what you are doing, and it kinda works. But lets say that I need the game to test if the player is looking at an entity with the identifier of test:name, how do I make it look for that specific entity, and then run something like a function if it does?

Sorry for the butt load of questions btw, Ive been researching raycasting, but really found nothing

[woeful pollen]

player.getEntitiesFromViewDirection() has an interface to query things.

so...

player.getEntitiesFromViewDirection({ type: 'your:entity' })

[grand vapor]

Since there is an interface, is there a way to make it run a if statement?

[woeful pollen]

?

I dont know what that has to do with the interface

[grand vapor]

Bad image, but better than I can describe it

Like direct line of sight

[woeful pollen]

okay so

instead of using the interface just check it's typeId in an if statement

then use an else statement

[grand vapor]

Ima try something real fast

function raycast () { world.getAllPlayers().forEach((player) => { if (player.hasTag("Player")) { if (player.getEntitiesFromViewDirection({ type: 'test:name' })) { player.runCommandAsync('say hi') } } }); }

That is what I did

[woeful pollen]

I was going to say

you could probably do that

[grand vapor]

And it just said hi constantly

[woeful pollen]

oh

[grand vapor]

Im so confused... Sorry for a lot of questions

[woeful pollen]

^

[grand vapor]

Just did else command

Nothing changed

[woeful pollen]

show me the code

[grand vapor]

function raycast () { world.getAllPlayers().forEach((player) => { if (player.hasTag("Player")) { if (player.getEntitiesFromViewDirection({ type: 'test:name' })) { player.runCommandAsync('say hi') } else { player.runCommandAsync('say no') } } }); }

[woeful pollen]

you didnt do what I said

[grand vapor]

I used else

[woeful pollen]

thats not all I said

lmao

use forEach for the entities aswell

then make an if statement checking its typeId

then use an else statement

and remove the interface stuff

[grand vapor]

if (player.getEntitiesFromViewDirection()) { } The stuff the I removed in the interface stuff, right?

[woeful pollen]

Yes.

[grand vapor]

And now when you say for each, do you mean something like forEach(({ type: 'test:name' }))

[woeful pollen]

look at what you did for getAllPlayers

do the same thing with getEntitiesFromViewDirection

[grand vapor]

Okay, Im still confused and stupid when it comes to this

Do I put it in the interface?

[woeful pollen]

...

[grand vapor]

cause there is no world.getAllEntities

[woeful pollen]

Im not telling you do anything with any interfaces anymore

I told you to remove the interface within the getEntitiesFromViewDirection

[grand vapor]

And i did

[woeful pollen]

where is this coming from?

I didnt say anything about doing this

[grand vapor]

You say to you the same thing that I did for getAllPlayers

[woeful pollen]

...

[grand vapor]

But like, what how tf does that work?

[woeful pollen]

forEach

thats what you used

[grand vapor]

So something like forEach(({ type: 'test:name' }))

[woeful pollen]

no-

[grand vapor]

Then what do you mean for each

[woeful pollen]

did you code the function up there yourself

[grand vapor]

Yes

[woeful pollen]

I dont understand how you dont know what I mean then

putting the interface from getEntitiesFromViewDirection into forEach does not make sense

and also I said we are not going to be working with interfaces in general so remove it

[grand vapor]

I removed the interface stuff in getEntitiesFromViewDirection

[woeful pollen]

yeah but you keep suggesting to put it into forEach

[grand vapor]

` world.forEach((type: 'test:name' ) => {

        })` 

Is even near the right thing

[woeful pollen]

I dont if im explaining poorly, if I am, im sorry.
I need to go now

[grand vapor]

Alr

Thanks for trying

Sorry

[woeful pollen]

I recommend looking at the api documents and maybe some basic js docs.

[grand vapor]

Alr

[woeful pollen]

here's the site ive been using often for minecraft's script api: https://stirante.com/script/server/1.13.0/
you could look at this for basic js: https://developer.mozilla.org/en-US/docs/Learn/Getting_started_with_the_web/JavaScript_basics

[grand vapor]

Ill look at it

Thanks

[grand vapor]

@woeful pollen Thanks for the help. My brain turned on for once and I got it working! Thanks man!
