2D trigger event

[FouriusCraft]

hello I want to ask for help why this is happening. First I apologize for the language because English is not my main language

a few days ago I just bought playmaker then tried to learn from the official youtube channel then one of the "Drag and Drop UI" videos has an error when I practice it

Hi.
It might be that the collider is not set as trigger

[FouriusCraft]

The collider has been set trigger

Hi.

I noticed on the video that this one is not set as trigger

I just figured out that a rigidbody 2d is needed for the target, but I don't know why.
Anybody knows?

Hi.
For collision events source or target needs a rigidbody (its just how unity works), but i believe trigger event not (not sure)

else try to use overlap or cast actions (they do not require rigidbodies)
