1.15.2 Enchantment Table Decreasing Higher Enchantment Level Chances

I tried to decrease chances with this code it works but only for offer showings. How can I change the result ? Please help me

Code (Text):

p=enchantmentTable.getEnchanter();
        if (enchantmentTable.getOffers() != null){
            if (enchantmentTable.getItem() != null){
                inputItem= enchantmentTable.getItem();
            }
            newInventory=enchantmentTable;
            offerList= enchantmentTable.getOffers();
            for (int i=0; i<offerList.length ; i++) {
                if (offerList[i] != null){
                    if (offerList[i].getEnchantmentLevel() >=5){
                        if (luck< development.fiveLevelChance){
                            continue;
                        }else{
                            offerList[i].setEnchantmentLevel(offerList[i].getEnchantmentLevel() -1);

                        }
                    }
                    if (offerList[i].getEnchantmentLevel() ==4){
                        if (luck< development.fourLevelChance){
                            continue;
                        }else{
                            offerList[i].setEnchantmentLevel(offerList[i].getEnchantmentLevel() -1);
                        }
                    }
                    if (offerList[i].getEnchantmentLevel() ==3){
                        if (luck< development.threeLevelChance){
                            continue;
                        }else{
                            offerList[i].setEnchantmentLevel(offerList[i].getEnchantmentLevel() -1);
                        }
                    }
                }
            }
            newInventory= new PrepareItemEnchantEvent(enchantmentTable.getEnchanter(), enchantmentTable.getView(), enchantmentTable.getEnchantBlock(), enchantmentTable.getItem(), offerList, enchantmentTable.getEnchantmentBonus());
            enchantmentTable=newInventory;
        }

 

Offers are just previews. When I change the offer result doesn't change. For example with this code I put my diamond sword to enchament table and I saw Sharpness 2 instead of Sharpness 5. But when I click to the offer end get the Item i see Sharpness 5 sword. I want to change this Sharpness 5 result to Sharpness 2 if offer shows so.

 

No sir, I need to change the result Item. It does not change when I change the offer

 

But when I get the offer

 

this happens

 

Ok, now I am trying it I was already working on it but thanks to you now I am sure this will work

 

It worked thanks ♥
