line 2d drawing off

jbskaggs

using unproject. How do I get a line2D to stop on a node's origin (the muzzle) which is offset from the parent.

If I center the node on the parent it works. But if I move the node forward then the line2D ends up off, originating past the healing tower. see the pink line in image above

Currently using this line of code for the muzzle:

Global.from = get_viewport().get_camera().unproject_position(get_node("../muzzle").global_transform.origin)

then in my heal script which calls the line2D

func _ready():
	Global.to = get_viewport().get_camera().unproject_position(global_transform.origin)
	if !get_node('Line2D')==null:
		get_node('Line2D').add_point(Global.from)
		get_node('Line2D').add_point(Global.to)

I appreciate the help :)

Can you provide your node hierarchy and specify which script is attached to which node?

first image is the healer.tscn where the heal.tscn is instanced,

2nd image is the heal.tscn which draws the line back to the healer

Shouldn't the muzzle node be parented under rabbit_healer node if this node is handling healer's rotation?

hmm let me test that

jbskaggs

Nope same exact behavior.

Try to add a small visible debug sprite as a child to the muzzle node to check where it's positioned when the line is drawn. Test out with different positions of the muzzle and different rotations of the healer. See if there are any suspicious patterns.

thats what I have been doing. The sprite stays on the muzzle on tip of gun. The line always vears off to right and rear. The further forward I move the muzzle the bigger the distance between muzzle and line as it moves further to right..

Update Global.from inside the heal_shot function. Currently it's only initialized when healer is created and it doesn't account for any subsequent rotations.

Welp that was it. Thanks!

Btw, there's no need to use any global variables for this. Simply calculate both endpoints in the heal_shot function.
