how i can modify a entity hitbox ?

[MineLight1689]

Hello, i'm want to find a way to modify the hitbox of scprotect:scp_096 to a square box of 1x1 i tried using a script in servers_scripts but it simply does not work, thanks in advance. (Sorry for my bad English)

i'm using kubeJS 2001.6.5-build 16 forge for 1.20.1
and rhino 2001.2.3-build 6 forge
architectury API 9.2.14

EntityEvents.spawned(event => { let entity = event.getEntity(); if (entity.getType() == 'scprotect:scp_096') { entity.setBoundingBoxWidth(0.5); entity.setBoundingBoxHeight(0.5); } });
