Thank you for the links, I used the first one to learn about loot tables before beginning, it was quite helpful actually, the second one should definitely come in handy if I do make my own from scratch, too!
To provide some more info, I'll put the global_loot_modifiers.json here, as well as list the file structure, just to make sure everything is correct.
{
"replace": true,
"entries": [
"dragonmounts:dragonmounts/aether/chests/simple_dungeon",
"dragonmounts:dragonmounts/ghost/chests/woodland_mansion",
"dragonmounts:dragonmounts/water/chests/buried_treasure",
"dragonmounts:dragonmounts/fire/chests/desert_pyramid",
"dragonmounts:dragonmounts/forest/chests/jungle_temple",
"dragonmounts:dragonmounts/ghost/chests/abandoned_mineshaft",
"dragonmounts:dragonmounts/ice/chests/igloo_chest",
"dragonmounts:dragonmounts/nether/chests/bastion_treasure"
]
}
file structure:
[datapack name] / data / forge / loot_modifiers / global_loot_modifiers.json
[datapack name] / data / dragonmounts / loot_modifiers / ghost / chests / abandoned_mineshaft.json
there are more folders in loot_modifiers for the other dungeon chests, all intended - as a test right now - to convey a 100% spawn chance for a dragon egg (usually it is around 7.5 to 30%). However testing with this I found no eggs anywhere, and like I said, JER does not show any drop information for dragon eggs, but does show drop information for other items, chests and mob drops both.
For completness sake, an excerpt of one of the loot table modifiers, this one for the mineshaft:
{
"conditions": [
{
"condition": "forge:loot_table_id",
"loot_table_id": "minecraft:chests/abandoned_mineshaft"
},
{
"condition": "minecraft:random_chance",
"chance": 1.0
}
],
"breed": "dragonmounts:ghost",
"type": "dragonmounts:dragon_egg_loot"
}
I appreciate all the feedback here so far, by the way, thanks for everyone who replied!
