block display anchor point?

[ripe field]

yo so i wanna make this sort of paintball gun thing, using block displays.
when i run the following code, it spawns the block display on its corner.
is it possible to make its anchor point be in its center somehow?

    if player's tool's name is "&6&lPaintball Gun":
        make player swing their hand
        set {_v} to vector from yaw player's yaw and pitch player's pitch
        set standard length of {_v} to 1
        spawn block display at player's head ~ {_v}:
            set {_display} to entity
            set (display item of {_display}) to red concrete
            set (display scale of {_display}) to vector(0.5,0.5,0.5)```

move it ~vector(-0.5,0,-0.5) iirc

(item display also works as it centers by itself but dont do that)

[ripe field]

nah cuz it doesnt spawn on the block grid

it spawns whichever way ur facing

[quiet lagoon]

set its yaw and pitch and fix rotation

[ripe field]

like this ? or wdym

            set (pitch of {_display}) to player's pitch```

im sorry are there any good resources on display entities

i cant find shit on docs

the translation for center of a block display is negative half its scale

[ripe field]

yeah but its not aligned on any axis so it doesnt work by just using the vector as he suggested

[zenith tinsel]

or just use item displays

Set display translation to vector(-0.25, -0.25, -0.25)
