"you misunderstood what I mean.\n \n\n\n                if (entity.getActiveItemStack().getItem() instanceof BaseBow) {\n                    return 0F;\n                } else {\n                    return (float)(stack.getUseDuration() - entity.getItemInUseCount()) / 20F;\n                }\n            }\n\n\n\tchange the 0F to 1F does not matter because what are you trying to do is to change the bow's model correspond to the bow's pulling duration (time pulled), which you've done that in the else statement. But the else statement is never going to be reached because the item you are holding is an instance of the custom bow class so it will always return the value in the if statement\n \n"
