Some terms mean very particular things in ASI, it is best to define them properly
Beegs are scaled-up players, much bigger than the normal 1.8 blocks tall.
Or maybe, a beeg is a normal player... provided you are a tiny. Size is relative.
Tinies are scaled-down players, much smaller than the normal 1.8 blocks tall.
Or maybe, a tiny is a normal player... if you are a beeg. Size is relative.
Scale is how much bigger an entity is than normal.
A normal entity is scale 1x, they may be scaled up or down to produce a beeg or a tiny of that entity. It could be anything, cow to enderman to minecart and falling block.
Size is the actual size of an entity. Even at the normal scale of 1x, some entities are just bigger than others, evidenced by the size of their hitbox.
For example, the hitbox of a chicken is much smaller than that of an enderman or ravager.
