Be able to know which point of the rope is colliding

[Corneguidouille]

Hi,
I have a feature request.
With your new collision system implemented, I need to know which point of the rope is colliding or not from gdscript.
Something like get_colliding_points() or is_point_colliding(index)
This would be super usefull!
Do you think this is something you can consider?
Thanks :)

Yes, will do 👍

[Corneguidouille]

Terrific! Thanks!

[Corneguidouille]

Or maybe through a signal?

[Corneguidouille]

Or both :)

It will be a list of contact points that you can retrieve from the rope.

[Corneguidouille]

Ok, great!

Implemented in 6389290.
You can get a preview build here.

Thanks a lot for your work!
Unfortunately, there is an issue.
If the Num Constraint Iterations is greater than 1 (10 by default), it will report the same contact point multiple times in the vector.
This is because resolve_collisions is called in this loop:
`for (int _ = 0; _ < num_constraint_iterations; ++)More actions
{
for (int i = 0; i < points.size() - 1; ++i)
constraint_segment(&points[i], &points[i + 1], simulation_weights[i], simulation_weights[i + 1], seg_lengths[i]);

    if (resolve_collisions_while_constraining)
        _resolve_collisions(delta);
}`

I suppose you can fix it by checking if the contact point already exist in the vector before pushing it.

Oh right, that was an oversight. I think it should only report the collision points of the last iteration.

Fixed in most recent build.

[Corneguidouille]

Yes, no more issue. Thanks a lot!!!

You're welcome!
If you build something cool, feel free to submit a showcase video :)
