2D physics pin joint angular limits do nothing

Tested versions

Godot 4.2.2 stable mono

System information

Linux - Forward+

Issue description

I have a very simple setup of a Node2D with two rigid body children and a pin joint child. The pin joint affixes the two bodies together. I attempt to enable "angular limit" but no matter what settings I use for the bounds nothing is affected. The body pivots just fine and can be motorized without issue. According to the code it is enabled.

Steps to reproduce

• create a Node2D scene
• create 2 rigid bodies as children, each with collision shapes and sprites
• create a pin joint 2d and attach the two bodies
• enable angular limit
• instantiate this scene into a different, larger scene
  on run the limb just falls loosely

I just encountered the same issue.

1) I'd propose renaming the issue to:

So it's easier to find and more precise

PinJoint2D doesn't respect angular_limit

2) People in the forum mentioning it:

• "Angular limit on pin joints doesn’t work"
• "PinJoint2D - angular limits don’t work?"

3) Open issue

There is also an open issue which requests this feature. This could be closed now since the feature was "added" 🙃 (and now can be tracked via this issue)

4) Worked at some point

According to this video it seemed to work at some point (even though they never were hard limits) so I am trying to figure out when it broke.
This seems to be the code responsible. Doesn't look crazy complicated but I have no experience with C++.

Same issue here

In my own limited testing of this, I've noticed that sometimes the values supplied in the editor or via code for the angular limits are ignored, and sometimes they are not. In remote debug the limits snap back to a default of -180 to 180 when they are being ignored.

(I also tried to change the values withing the remote session, but I got weird behavior--things flying around wildly by themselves.)
