It Says "No entity was found".

i was initially going to use barriers as the hitbox for the tardis but the model was not exactly 3x3 meaning you coulldnt enter inside and when you take off an land in a new place it would remove the area around it, it also doesnt work with height calculation because it relies on looking for air blocks in a certain radius of the box , i used a polar bear as its hit box was big enough so you could still have a way of not fully walking through the model and still be able to enter it i use a mod called solid mobs which allows it so you cant walk through mobs at all
