the default method:

[upper sapphire]

so

[clear wigeon]

yeah

[upper sapphire]

is this the face that is oriented correctly?

the face or the side as you wish

[clear wigeon]

yeah!

[upper sapphire]

and I assume the one behind is "inside out" ?

[clear wigeon]

this is from the other side, none are visible

[clear wigeon]

well they are all facing positive Z

while they should all be facing pretty much outwards

[upper sapphire]

ok so all these bedrock, redstone and blue text display are essentially like a group (a single thing), right?

[clear wigeon]

they are indicative blocks of whether everything is correctly rendered

the text displays are what actually renders

[upper sapphire]

ah okay

and this fillUp method is what generates these blue text displays?

[clear wigeon]

yeah

[clear wigeon]

(not always)

[upper sapphire]

I assume fillUp is called six times, once for each face?

[clear wigeon]

yeah

[upper sapphire]

show the entire fillUp method and also where you calll it

you can send screenshots, nobody will copy paste it anyway

[clear wigeon]

private void fillUp(Vector3f overallCenter, ItemDisplay owner, Vector3f ownerPos, Color color, Vector3f p1, Vector3f p2, Vector3f p3, Face face, World world, float pitch, Transformation transformation) {
        int blockCount = 8;
        Vector3f v1 = new Vector3f(p2).sub(p1).div(blockCount);
        Vector3f v2 = new Vector3f(p3).sub(p1).div(blockCount);

        for (int i = 0; i < blockCount; i++) {
            for (int j = 0; j < blockCount; j++) {
                Vector3f pos = new Vector3f(p1)
                        .add(new Vector3f(v1).mul(i))
                        .add(new Vector3f(v2).mul(j));

                //owner.addPassenger(spawnInwardFacingPassengerDisplay(world, color, ownerPos, pos, pitch, transformation, face.getFaceCenter(), overallCenter));
                owner.addPassenger(this.spawnPassengerDisplay(face, world, color, ownerPos, pos, pitch, transformation));
            }
        }
    }

    @SneakyThrows
    private TextDisplay spawnPassengerDisplay(Face face, World world, Color color, Vector3f carrierPos, Vector3f selfPos, float pitch, Transformation transformation) {
        TextDisplay e = world.spawn(new Location(world, selfPos.x, selfPos.y, selfPos.z, 0, pitch), TextDisplay.class);

        Vector3f translationCopy = (Vector3f) transformation.getTranslation().clone();
        translationCopy.add(selfPos).sub(carrierPos);

        Vector3f scale = new Vector3f(2.5f);
        Transformation transformationCopy = new Transformation(translationCopy, transformation.getLeftRotation(), scale, transformation.getRightRotation());

        e.setBackgroundColor(color);
        e.setTransformation(transformationCopy);
        e.setAlignment(TextDisplay.TextAlignment.CENTER);
        return e;
    }

Vector3f translationCopy = (Vector3f) transformation.getTranslation().clone();
translationCopy.add(selfPos).sub(carrierPos);
is due to there being a single carrier where each text display rides it and has its transformation adjusted

[upper sapphire]

wait so you attached all these text displays for each side on some entity? so 6 entities each has 64 text display passengers?

[clear wigeon]

no

there is 1 carrier

[upper sapphire]

show the method where you call fillUp pls

[clear wigeon]

so 1 carrier has 383

v

[upper sapphire]

gosh that's so much code

what's the Face ?
is it an enum?

[clear wigeon]

isn'tttt itttt?

[upper sapphire]

it's okay dw

[upper sapphire]

aand what is Direction?

[clear wigeon]

(it's probably incorrect, but we can differentiate between the faces this way)

so only 'down' is correct

but not entirely

since it's in the correct position, but doesn't render from the other side

[upper sapphire]

omg 😭 figure out how FRONT, BACK, LEFT, RIGHT correlate to positive/negative x/z

then when you have the Transformation of each individual text display, for these four faces set it to one of this: java Quaternionf rot = new Quaternionf(); new Matrix3f().rotateY((float) Math.PI).get(rot); transformation.setLeftRotation(rot);

[clear wigeon]

what about this?

[upper sapphire]

yes because it has to face against where you look it from

press f3+b to see where it's facing

[clear wigeon]

I think any yaw changes to it would rotate it around the passenger's loc

[clear wigeon]

ah alright

[clear wigeon]

I'll confirm whether that's the case

[upper sapphire]

my bad you need to use rightRotation instead of left

[clear wigeon]

what if I already have a right rotation assigned?

[upper sapphire]

note that where the entity faces is not the same as where the text is facing

give me a sec

I'm having trouble understanding how to convert angle axis form into quaternion because Transformation.setLeftRotationexpects a quaternion

[clear wigeon]

wrap with new Quaternionf()

[upper sapphire]

alright here are the quaternions for leftRotation ```java
// facing positive X
[0f,0.7071067811865476f,0f,0.7071067811865476f]
// facing negative Z
[0f,1f,0f,0f]
// facing positive Z (default)
[0f,0f,0f,1f]
// facing negative X
[0f,-0.7071067811865476f,0f,0.7071067811865476f]

facing positive Z means you should look towards negative Z to be able to see the text

I'll have to look at how to get them nicely by pi, 2pi, 3pi rotations around Y axis

[clear wigeon]

where do you expect me to apply them?

[clear wigeon]

here ?

[upper sapphire]

wherever you have face

[upper sapphire]

there's so many arguments I cannot keep track of which is which
but here in fillUp you pass a Transformation as the last argument

this will look ugly but you could make a switch (face) inside the for loop then call setLeftRotation(new Quaternionf(...)) based on the face

[clear wigeon]

yeah my methods are not working

[upper sapphire]

I believe that is rightRotation

[clear wigeon]

it's not

I set their yaw & pitch

and uh

[clear wigeon]

this stuff

pops u[

it rotates the entity around the carrier's location

[upper sapphire]

I mean if you're not scaling any of these, you should only touch left or right rotation, and leave the other one as default (identity matrix)

[upper sapphire]

uh

do not change yaw and pitch of textDisplays

[clear wigeon]

Understood.

[upper sapphire]

i mean you could but then do not use transformations (except for up/down facing ones)

now I may be wrong here but in most cases left rotation is only what you want, right rotation is just going to skew (e.g. turn a cuboid into paralelepiped)

just realised that changing yaw and pitch works for text displays too lol

sorry @clear wigeon in this case you can just change yaw to -180f, -90f, 0f, 90f

[clear wigeon]

I just told you

[upper sapphire]

I'm not sure why didn't it work for you earlier then

[clear wigeon]

that it breaks

cuz they are riding an entity probably

[upper sapphire]

combining entity rotation & text display rotation is just terrible

[clear wigeon]

it just rotates them around that

[upper sapphire]

set their yaw and pitch to 0, 0 then and apply rotation within the Transformation ?

that should work

[clear wigeon]

how exactly?

rotate leftRotation?

[upper sapphire]

I just tested in singleplayer using commands: when text display A is riding on a test display B,
(A is passenger, B is carrier),
changing B's yaw and pitch does not affect A's yaw and pitch

[upper sapphire]

seems like they all have fixed location and yaw&pitch, but different translations, which is okay, you just need to change leftRotation in here based on the Face

[clear wigeon]

so like this?

[upper sapphire]

when the text displays are translated through a Transformation, text's actual position in the world is offset from the entity's position
so if you go and change entity's yaw and pitch, the text would move around too

[upper sapphire]

what is Direction.leftRot?

[upper sapphire]

for UP and DOWN you will need two more quaternions, I'd leave that up to you

but yeah that looks good

[clear wigeon]

doesn't

wor

k

[upper sapphire]

where is this code?

inside spawnPassengerDisplay?

[clear wigeon]

yeah

[upper sapphire]

remove that line and

okay nevermind

let me analyse this code a bit

are you sure face.direction is correct and not the same for all faces?

[upper sapphire]

uncomment this e.setText then send a screenshot ingame

[clear wigeon]

it will be all white

[upper sapphire]

huh?

[upper sapphire]

oh

[clear wigeon]

this is the indicator

[upper sapphire]

that's alright

I didn't notice it sorry

[clear wigeon]

I ensured that these are indeed opposites

[clear wigeon]

it kind of works if there is no initial right or left rot

otherwise breaks

[upper sapphire]

where would initial left or right rotation come from if not this?

that may be what confused me the entire time

[clear wigeon]

wdym by 'this'?

I simulate generating a block display

[upper sapphire]

this = setting a quaternion

it sounds like you got a rightRotation from somewhere else too and those two combined

btw if you'd like to debug each one separately, you can:
instead of java owner.addPassenger(this.spawnPassengerDisplay(face, world, color, ownerPos, pos, pitch, transformation));do this:java TextDisplay ent = this.spawnPassengerDisplay(face, world, color, ownerPos, pos, pitch, transformation); ent.addScoreboardTag("_" + face.name() + "_" + i + "_" + j); owner.addPassenger(ent); then in game /data get entity @e[tag=_UP_0_0]

[clear wigeon]

and wish to, in its place, render text displays as to show a custom texture

[clear wigeon]

I give it initial parameters in chat

[upper sapphire]

do you really need a rightRotation though?

[clear wigeon]

yes

[upper sapphire]

what for?

[clear wigeon]

not sure

it's a bit too long to explain that now xd

same with why they need to be a passenger

[upper sapphire]

if you want to rotate everything at once, like this #help-development message
you probably should not use rightRotation, but instead combine the global rotation (for the entire thing) with each textDisplay's local rotation (which is different for each side)

(I think multiplying the Direction.leftRot(...) on the left and the global rotation on the right will result in a correct quaternion, but not sure)

also I'm going to sleep now, hope you will manage to figure it out

cheers o/

[clear wigeon]

gn

[clear wigeon]

Btw @upper sapphire I couldn't manage to do it

Just to let you know

[upper sapphire]

sorry to hear that 😦
what was the closest you got though?

[clear wigeon]

I completly changed my tactic for rendering and hadn't tested with text displays yet

I'll let you know once I test whether I'm smart enough for this stuff
