Space State picks up imaginary collision along vertical line

[gray crag]

Is get_point_position() relative to the line?

[indigo tangle]

Yup. As I said, the collissions usually work, stopping the line when it hits a platform, but like 20% of the time with platforms, it won't register, and of course, the line collides with the foreground tilemap in x = 96 no matter what.

I'm leaning more and more towards this being a bug with the engine itself

And thanks for responding, btw. This issue has been driving me mad

[gray crag]

But if it's a relative position and the ray query requires absolute positions...

Very unlikely that it is a bug

[indigo tangle]

Oh...

Busy rn but I'll get back to you in an hour or two, hopefully with good news. Thanks😄

[indigo tangle]

You were completely right. When adding the Line2D's global position to points between which I wanted to check for a collission, it works with no issues at all. Thank you so much! 😄

My final code:

extends Line2D

@export_custom(PROPERTY_HINT_LAYERS_2D_PHYSICS, "") var collision_mask = PROPERTY_HINT_LAYERS_2D_PHYSICS

var grav = ProjectSettings.get_setting("physics/2d/default_gravity")

var dotGap = 0.1 # How many seconds of travel go between each dot

var space_state

var globalpos

func make_points() -> void:
    var yvel = get_parent().chargedJumpPower
    var xvel = get_parent().chargedDirectionPower
    clear_points()
    for i in range(0, 40):
        add_point(Vector2(i * dotGap * xvel, 0.5*grav*(i*dotGap)*(i*dotGap) - yvel * (i * dotGap)))
        if (i < 2):
            pass
        else:
            var query = PhysicsRayQueryParameters2D.create(get_point_position(i - 1) + globalpos, get_point_position(i) + globalpos, collision_mask)
            if space_state.intersect_ray(query):
                remove_point(i)
                add_point(space_state.intersect_ray(query).position - globalpos)
                break
    queue_redraw()
func _draw() -> void:
    for i in range(get_point_count()):
        draw_circle(get_point_position(i), 2, Color.WHITE)
        if stopline and i == get_point_count() -1:
            draw_circle(get_point_position(i), 4, Color.GREEN)

func _physics_process(delta: float) -> void:
    globalpos = get_global_position()
    space_state = get_world_2d().direct_space_state
    if get_parent().charging:
        make_points()
    else:
        clear_points()
        queue_redraw()
