Detect trigger touching another trigger?

Questions & Answers
1

Hi, I’m trying to make a prototype for a physics mech building game,
to do this the player spawns physics pieces and can move them around with thier physics turned of (I set the Rigidbodies to isKinematic = true)
the player would then be able to join up pieces and hit “simulate” to turn on physics for the whole mech all at once

So to be able to weld pieces together i need to detect if they are touching, but i don’t know how

the functions OnTiggerStay, OnCollisionEnter etc. all require colliders that are “solid”, they can’t be triggers or have isKinematic = true

Is there a way I can detect these triggers colliding other triggers?

Any help would be much appreciated

You can receive a message with a kinematic rigidbody only if the other collider has a non-kinematic rigidbody. You can then add a rigidbody to each part, set useGravity false, freeze all movement / rotation and set kinematic only the one you move.

Btw, you should disable the picking when the player is dragging the mouse, and the rotations axis are a bit hard to select. Also, you could improve your outline shader by drawing them before the object, that would remove the outlines inside it. Sort of like that shader. But that’s a matter of taste I guess.
