Conditions.weapon.numericObservation

Call as

Conditions.weapon.numericObservation(value)

Record the dependency Conditions.weapon.numericObservation, then call it by that name. A namespaced call does not pass self: use a colon call or pass the object yourself.

What it does

Accepts a readable, nonnegative, finite number from a weapon observation and returns it unchanged; anything else becomes nil with a reason.

Arguments

Name	Type	What it does
`value`	`any`	Observed value, such as an expiration time or swing speed.

Returns

1	`number \| nil`	The value, or nil when it is not usable.
2	`string \| nil`	Reason for nil: restricted-value or invalid-weapon-observation.

Editions

Built In helpers are registered on every edition. What differs is the game API they read; where one is missing the helper falls back or returns nil with a reason.

It reads no game API directly.

Secret values (Retail and Forever)

On Retail and Forever the game hands addons secret values. This helper checks what it reads (addon.Platform:CanReadValue) and returns nil with a reason such as restricted-value instead of a secret it cannot compare. Treat nil as unavailable, not as false.

How the addon calls it

Weapon Enchant Time Remaining (evaluate)

local duration,why=numericObservation(expires)

Weapon Enchant Stacks (evaluate)

local count,why=numericObservation(charges)

Conditions.weapon.swingSpeed
```
return numericObservation(speed)
```
