Animation Clip Won't Play Despite Transition Showing in Animator

Question

I'm following this Unity Animation Rigging tutorial by TheKiwiCoder. What I have now is a rig layer containing all kinds of constraints. The tutorial instructs to add an animator to this rig layer and record animation in the Animation window.

I recorded a clip, and use code to play it.

public void Equip(Guns newgun)
{
   if (weapon)
   {
      Destroy(weapon.gameObject);
   }
   weapon = newgun;
   weapon.transform.parent = weapon_pivot;
   weapon.transform.localPosition = Vector3.zero;
   weapon.transform.localRotation = Quaternion.identity;
   rigController.Play("equip_" + weapon.Name + "_pose");

}

but even though the transition appears in the animator, it still won't play. Has anyone encountered this type of issue?

By the way, if I switch up the default like this, it will play the animation, although it doesn't play correctly. So I guess it may have something to do with the configuration?

And if i add the transition, it will end up like this (with no transition play at all, even if it shows transition in the animator):

and this:

Answer 1

Your animator doesn't have any transitions (other than the default Entry transition). A transition would be represented as a line between states (notice the line from "Entry" to "character_unarmed").

To add a transition:

1. Right-click on the state you want to transition from.
2. Left-click on the state you want to transition to.
3. A new line appears between the states. If needed, click on the line to select it, and adjust the transition settings in the Inspector.

See the official documentation on the Animator Controller and Transitions for more info.
