[Version 4.10] Time Existed Modifier

Time Existed Modifier (Inherits from Modifier)

• bonus_per_seconds: (Modifiable Value Object) bonus applied each time seconds have passed
• seconds: (Modifiable Value Object) Every how many seconds will the value increase by bonus_per_seconds
• max_bonus_percentage: (Modifiable Value Object) The maximum value bonus_per_seconds can reach
• mode: (String) How the bonus_per_seconds is calculated when there are multiple players near (up to 128 blocks) the mob spawned. If omitted, defaults to "average"
  • "average": Makes an average of time played of the nearby players
  • "sum": Sums the time played of the nearby players
  • "nearest": Takes into account only the time played of the nearest player

Notes

• If operation is set to "add", the final bonus_per_seconds is added to the modified value, else if operation is set to "multiply", bonus_per_seconds is threated as a bonus percentage. Check examples.

Example

In this example the chance for the creeper to get speed on spawn increases by a flat 5% every hour.
So after 2 hours of play the chance will be 0.15 + (0.05 * 2) = 0.15 + 0.10 = 0.25 = 25%

{
    "target": "minecraft:creeper",
    "potion_effects": [
        {
            "id": "minecraft:speed",
            "chance": {
                "value": 0.15,
                "time_existed_modifier": {
                    "operation": "add",
                    "bonus_per_seconds": 0.05,
                    "seconds": 3600
                }
            }
        }
    ]
}

In this example instead, the chance increases by 25% every hour (doubles every 4 hours).
So after 2 hours of play the chance will be 0.15 * (0.25 * 2 + 1) = 0.15 * 1.50 = 0.30 = 30%

{
    "target": "minecraft:creeper",
    "potion_effects": [
        {
            "id": "minecraft:speed",
            "chance": {
                "value": 0.15,
                "time_existed_modifier": {
                    "operation": "multiply",
                    "bonus_per_seconds": 0.25,
                    "seconds": 3600
                }
            }
        }
    ]
}
