Title: Trigger Event recognizes children? [SOLVED]
Post by: kici on March 16, 2016, 09:49:03 AM

Scene: "parent" object, with a rigidbody and a capsule collider tagged as "Player".
Child object with a trigger on it as well (For other purposes) and not tagged as Player. (trigger covers more area than its parent, therefore its bigger)

Why does the trigger event on the Parent actually use the child as a trigger detection? The FSM is on the Parent itself, if this is a bug can you fix it please? or how can I?
If this is done purposely, how can I ensure that it only uses the parent for this specific FSM / trigger event...?

Thank you.

Try adding rigid body tags set to IsKinematic to each child-

Is this a bug though ? Why would the fsm read a trigger from a child when not specified ?

I prefer to stay away from adding another Rigidbody on there as I'm targeting a mobile build.

I just want to confirm that adding a Rigidbody to the child solves this issue.

I'm pretty sure its a Unity issue and not a Playmaker one- if its set to isKinematic its not as intensive as a live rigid body

Okay,  thanks appreciated. I'll keep this as a solution for   now.

Hopefully gets resolved in the future.

I think what you're describing is just the way Unity works:
http://answers.unity3d.com/questions/410711/trigger-in-child-object-calls-ontriggerenter-in-pa.html

It's the Unity solution for setting up compound colliders.

So the workaround might be the real solution, at least until Unity redesigns that system someday...

Makes sense, thanks for clarifying this and proving the links.

Awesome support.

I confirm : this issue is still there in 2019 and the workaround works too  :-\

This has changed, afaik. There are composite colliders now, which require a rigidbody only on the parent, and you must tick the composite box on each collider underneath. It then treats the whole thing as one.

Hi.
I never knew that existed!

We learn every day :D

I usually have a 'Data' fsm on the game object with the collider which has a game object variable holding the parent. which i can then get for referencing
