Position in 3D

Genie

Hey, i try to figure out how to handle the position in 3D space.

When i want my Label3D node to have the position of another 3D object, i tryed to assign its transform or global_transform or global_transform.origin to the Label3D but it's not appear on top of the 3D object.

Genie Disable depth testing for the label if you want it to be drawn over everything else.

Good to know, in my case the label3D spawned but somewhere else.
My 3D object contains several child objects and it seems like i cant get the position of its childs, eveytime i try to assign the Label to a child, it spawns at the parents position (actually at the origin position, which i defined in blender).

xyz

Genie Assign child's global_position to global_position of the label.

A 3D object dont have a position property.

xyz

Genie It's called global_translation in Godot 3.x

Genie

xyz

Oh i see, i dont worked with godot 4 yet.
I also tried global_translation already but with the same result.

xyz

Genie Let's see the code and the results.

Genie

xyz

func _on_Head_mouse_entered():
	tooltip = Label3D.new()
	add_child(tooltip)
	head.global_translation = tooltip.global_translation
	tooltip.no_depth_test = true
	tooltip.text = ("Text")

Tooltip should spawn at the head meshinstance, but it spawns at the character's feet.

xyz

Genie Your code is trying to assign tooltip's position to head's position. Shouldn't it be the other way around?

Genie

My bad, i tried to switch it and fergot to make it back. Still same result

xyz

Genie Still same result

And what is that result, opposed to what you expect?

The assignment should place the label at the origin of the node you're taking the position from. That origin may not be at the place you want it to be in respect to actual polygons. So check where your origins are.

I assign the label to the position of the head but it appears at its feet. I guess its because how i structured my model inside blender.

xyz

Genie Yeah, you may have placed origins of all your objects/meshes at the feet. This needs to be fixed in Blender.

Genie

So i set an own origin for each object but still have the same result. I figured out, when having an armature in blender, all objects that attached to it, get its origin in godot and ignore their own origins.

Centered box is the armature origin, you can see if you press on a child box, it isnt get it own origin.
I guess, doing something like that is not possible.

Genie I can only guess without seeing the Blender file.

I cant upload files here but thats how it looks like

How about adding bone attachment to the child bone then place tooltip at its position. (you can position the bone attachment wherever you want)

Genie

Gowydot

That is an inaccurate solution, since the bones are not object shaped. For tooltips there are other ways but that looks like a bug for me, which should be fixed.

xyz

Genie You likely didn't set things up properly in Blender. Again, hard to tell without inspecting the file.

I hope so!
