 All ''ModelPredicateProvider'' returns a float, which can be used to represent different states for the model, or a true/false value by returning ''1.0f'' and ''0f'' respectively. The float value will be clamped between 0.0f and 1.0f.
-Taking a closer look at the ''pull'' predicate, we see that we first check if the entity is null, as items can be rendered outside of a context where they are being used (i.e. dropped on the ground). We then make sure that the entity is using our item, otherwise the item could have the model predicate apply when not being used. Finally, we subtract the ''livingEntity.getItemUseTimeLeft()'' from the ''itemStack.getMaxUseTime()'' which tells us how many ticks the item has been held for. Because it takes 20 ticks or one second to fully charge a bow, we then divide this number by ''20.0f'' to normalize it to between ''0f'' and ''1.0f'' for the normal pull progress.

 All of this is useful, but is only half of the features we need to implement in order to have our item change its model.
