Navigation : How to find the coordinates of a Destination..?

Dad3353

I have a Navigation Region, containing a walled Mesh Instance 3D around which to Navigate. I can do this, giving a destination x and z to a CharacterBody3D (Elf...), which happily follows the Navigation Agent path, through the passages and on to the Target. I'm pleased; it's working. However, it's only reaching the coordinates that I set, by hand, after much trial and error. I had originally thought that the coordinates of the Target (Post 1 in the image...) would do the job, but, alas, that's not the case. I can find no relation between the numbers I fed in, and the actual 'Transform' numbers of the Post_1.
Once arrived at destination, I would like to have the Elf use the Agent to establish a new path, to Post_2. How do I get the numbers needed for this..? When I enter the 'Transform' numbers, the Path created is wildly off. I'm sure there's a simple way of establishing the x and z numbers needed, but it escapes me. The methods and examples I've looked at do not seem to use this same method (too simple..? Not useful to others..?), and my attempts at working it out using trial and (lots of...) error are not helping me understand the 'logic' that I'm missing. Here's a screenshot of the layout, with the actual numbers I've been using; how do I find the numbers needed to get from Post_1 to Post_2, please..? Thanks in advance; meanwhile...

Have a great day.

what do you mean set by hand?
You need to have the destination values in some sort of array or list so that the elf can iterate and move.
SO just create array of destination coordinates and do a loop
and when elf reached dest:
if current destination == array[0] then goto array[1] etc etc..
Something like that

Once again, I have failed to make myself understood. I have a starting point for the Elf, found by asking it its own coordinates, x and z. I have the Post_1 coordinates x and z, too, from the 'Transform' information. However, when I set these x and z numbers as Target for the Navigation Agent, it indicates a very different spot, usually well out of the Navigation Region. This tells me that the Navigation Agent isn't using the 'Transform' numbers for its calculations. I can make the Target destination to be correct if I enter x and z coordinates found by trial and error (putting in numbers until the traced path is correct...). What I want to know is how these coordinates can be established so that the Agent will find the Target, without me having to 'guess' them beforehand. How could the Nav Agent 'know' where to find Post_1, so as to trace the path to there..? I can deal with arrays et al once I find out how to declare the Target. Apparently it's not the 'Transform' x and z that the Nav Agent uses; what does it use..? It's these x and z values that the Nav Agent needs that I don't know how to find.
In the image I posted, we can see the Post_1 'Transform' coordinates (x 16, z -55...). However, the Nav Agent finds the Post_1 only if I use the Target_1 numbers (x -55, z -45...). What do these 'Target' numbers reference, and what would I need to declare to the Nav Agent to get this result..? For the moment, we can ignore looping, or going to the next Post. I need to have a method for finding any Post or potential Target.

Thanks for the reply; as of this morning I've solved the enigma, and found the solution. Much too easy, and I'm blind to have not recognised it earlier. I was trying to do something complicated, probably taken from an example that dealt with a different situation. Having established the Target x and z, with...
'''
var lv_targ_x = $"../Posts/Post_1".global_position.x
var lv_targ_z = $"../Posts/Post_1".global_position.z
'''
... I was using ...
'''
func find_path():
print("Finding Path...")
lv_curr_posi = self.global_position
lv_targ_posi.x = lv_targ_x
lv_targ_posi.y = 0.0
lv_targ_posi.z = lv_targ_z
lv_navi_agen.target_position = lv_curr_posi + lv_targ_posi # Wrong..!
'''
... where I should have used ...
'''
func find_path():
print("Finding Path...")
lv_curr_posi = lv_elf.global_position
lv_targ_posi.x = lv_targ_x
lv_targ_posi.y = 0.0
lv_targ_posi.z = lv_targ_z
lv_navi_agen.set_target_position(lv_targ_posi) # Correct..!
'''
It works, now, so on to the next step, changing the destination. I know how to do this so I'll close this topic, with many thanks.
