How i can change id ?
For the Mcreator versions that correspond to Minecraft 1.8, the ID of an item, block, weapon, etc is modName:itemName. Fore 1.7.20 and before, I don't know. For the 1.8 ones just make the title of the modification you're adding to the mod into the second half of the ID you want for it, and the first half is decided when you export it and put a Mod Name for it. In the test environment it's testEnvironment:itemName or something. You can see this by pressing F3 and H at the same time, then going into the creative menu. It should show the item IDs and/or numbers and NBT values.
heres a little easier way that you can use in mcreator for the future before you make a block/item you can change the id by going to the preference/Settings and head towards block/item IDs this well only work before you make your block/item but changing a ID to a driffernt id you might have todo what @Mr_Alpha said
@Brich036 i put ID 9000 at blocks but in game it 424 ... wtf
lol im not sure might be a bug since ya know mcreator is getting pertty glichy right now
