A script that triggers a command when a custom entity spots another entity?

[brisk marsh]

trigger an event...

[supple lynx]

I have two braincells left and they are fighting for third place..

What I meant was facing direction of the entity, if for example they are facing a creeper. A command triggers.

[brisk marsh]

entity.target

😄

[supple lynx]

. . .

thanks...
