Incrementation

The /incmark and /incfact commands let builders and mobs change a numerical mark or fact by a given amount.

For example, if a player has a counter mark with a value of 5, this command updates the value to 6:

/incmark player counter 1

Negative values decrease the stored value. The following command decreases counter by two:

/incmark player counter -2

Both commands support integers and decimals. If a balance fact is 1.1, this command sets it to 1.6:

/incfact balance 0.5

Note: A numerical mark or fact does not have to exist before you increment it. If bosses_killed_count has never been set, /incfact bosses_killed_count 1 creates the fact with a value of 1.

Use cases

Incrementing marks and facts reduces the need to set a new value manually every time something changes. Useful patterns include:

• Load a certain number of mobs and set a fact to the same number. Each mob’s death can decrement the fact until it reaches 0, triggering something new.
• Increment a mark whenever a player kills a particular mob. After the value crosses a threshold, something different can happen.
• Increment a mark whenever a player triggers an action. Crossing a threshold might unlock new content.

Threshold conditions

Use mark_above and fact_above to check whether a mark or fact has crossed a given threshold. Adding not before either condition makes it pass when the value is not above the stated threshold.

mark_above access_level 2
not fact_above enemies_remaining 0
