do you have a recommendation for what you think would work?

I have found that the horses saddle slot is most likely 400, and armor slot is 401.. however I still cannot seem to add an itemstack, I have "mc.player.getRidingEntity().replaceItemInInventory(401, itemstack);" but still, in game nothing seems to happen I found out the info about the slot number in the file for the /ReplaceItem command,

your wild guess was correct,

I have looked quite a bit.. and I have also tested 0 and 1, and it just creates the item stack in my hotbar slots 0 and 1. I also looked through a bit of code for horses, and whenever saddle slot was brought up, I would see either 3, or -18, however, once again neither work, -18 crashes the game, and 3 simply adds it to hotbar

yes I know that, however, replaceItemInInventory asks or a number (which represents the slot), and then the itemstack, I do not know what the number for a horses saddle/horse armor slot is

am I able to just add it? or do I have to use NBT? (I do not know how to do either..)

simply, how do I add an itemstack to a horses saddle/horsearmor slot?
