MC-116477"delta" option for "item_durability_changed" trigger inversely compares damage
Quite simple, the check for change in damage is negative (oldDamage - newDamage). Just need to inverse that operation (newDamage - oldDamage).
Example advancement, placed in world/data/advancements/custom/delta.json, showing that losing 5+ durability requires checking for maximum of -5 rather than minimum of 5:
{
"criteria": {
"findme": {
"trigger": "minecraft:item_durability_changed",
"conditions": {
"delta": {
"max": -5
}
}
}
}
}
And the following commands to test it at will:
/advancement test @p custom:delta /advancement revoke @p custom:delta
A fishing rod pulling a mob will cause it to lose more than 5 durability, while other uses of a fishing rod causes it to lose less than that.

I don't understand the issue. We're comparing durability, not damage. It starts at (say) 100, and then is 99, and then 98, etc. The delta is the difference of previous and current, which would be -1 for "it has one less durability". Is this not correct?
Seems correct to me.
Aha, that does make sense. I was focusing on the damage, my bad! I'll close as WAI.
