Godot Version

4.6.1 (With Health, Hitboxes, and Hurtboxes 1.2.0)

Question

The health node definitely has a current variable, but it just doesn’t like it.

Could you please post a full script of the Health class?

## Health is used to track the owner's health, death, and revival.

## Emitted after damage is applied.
signal damaged(owner: Node, amount: int, applied: int)
## Emitted after damage is applied when death has occured.
signal died(owner: Node)

## Emitted after healing is applied.
signal healed(owner: Node, amount: int, applied: int)
## Emitted after healing is applied when dead.
signal revived(owner: Node)


## Emitted when damaged and entity had full health.
signal first_hit(owner: Node)
## Emitted when trying to damage an entity that is not damageable.
signal not_damageable(owner: Node)
## Emitted when damaging and current health is already zero.
signal already_dead(owner: Node)
## Emitted when trying to apply enough damage to an enemy to kill them and they cannot be.
signal not_killable(owner: Node)


## Emitted when trying to heal and entity is not healable.
signal not_healable(owner: Node)
## Emitted when healing and current health is already full.
signal already_full(owner: Node)
## Emitted when trying to heal a dead entity that is not revivable

Please always format your code as preformatted text with triple backticks ``` at the beginning and end of the code snippet, otherwise it’s unreadable in the current format, as you should probably see in your post.

Please also paste the script that generates the error.

Health is a class. You want to access current from health instead. (Note that the latter starts with a lower-case letter.)

Maybe your problem is using capital H Health, this references the type, whereas you want to use lowercase h health which is your variable.
