Has Potion Effect

Tests Has Potion Effect using the configured inputs. Its Boolean result selects whether the If body runs; it does not assign a numeric result.

Where to find it

If → Target Object: LivingEntity or a compatible subtype → Choose Operation → Effects. Requires Dev access to configure, then a successful compile to activate.

Result and behavior

Returns a Boolean test for If.

Configuration example

Block: If
Operation: Has Potion Effect
Target Object: LivingEntity target in this plot
Potion: Potion: Speed, duration 20 ticks, amplifier 0

Use this as an editor configuration: declare any Variables/collections first and choose real locations/eligible targets for your plot. It is not pasteable source code.

Restrictions and troubleshooting

The receiver must satisfy the declared native capability and remain eligible for the running plot. Player actions require an appropriate Play participant; a Build/Dev player is not automatically eligible.
