I'm using a cube MeshInstance as the RPG-character.
So I have 4 nodes in a 3D scene:
The kinematic body gets its own global 3D location (which is the same as the cube's),
The camera gets this 3D location and turns it into a 2D location on the computer screen.
I set these variables under func _process(delta).
And these variables change and seem to represent the cube's 3D or 2D-screen location as I move the character around in-game.
But when I try to use the screen-location in the Label node, its value stops changing as I move around.
I thought if I used getglobaltransform() to get the cube's location,
it'd be global.
How can I get RPG dialogue to appear above a 3D character's head in a 3D game?
Here's my code:
var direction = Vector3(0,0,0)
var myCube3DLoc = Vector3(0,0,0)
func _process(delta): #Use this for things you want to work every frame. e.g. movement.
myCube3DLoc.x = get_global_transform().origin.x
myCube3DLoc.y = get_global_transform().origin.y
myCube3DLoc.z = get_global_transform().origin.z
# print("myCube3DLoc using get_global_transform().origin.x, y, or z returns: ", myCube3DLoc)
onready var myCube3DLoc = get_node("../Cube_KinematicBody").myCube3DLoc
onready var myCubeScrnLoc = unproject_position(myCube3DLoc)
#unproject_position(Vector3) returns the 2D coordinate in the Viewport rectangle that maps to the given 3D point in worldspace.
myCube3DLoc = get_node("../Cube_KinematicBody").myCube3DLoc
print("Camera node says... unproject_position(myCube3DLoc) returns: ", unproject_position(myCube3DLoc))
onready var myCubeScrnLoc = get_node("../Camera").myCubeScrnLoc
# Called every frame. 'delta' is the elapsed time since the previous frame.
myCubeScrnLoc = get_node("../Camera").myCubeScrnLoc
myCubeScrnLoc = myCubeScrnLoc
#^This doesnt help. The value still doesn't change.
print("LableNode: myCubeScrnLoc equals: ", myCubeScrnLoc)
#^This does't change as I move the cube, even though it's under func _process(delta).
P.S. I also tried putting the label node underneath the kinematic one. It doesn't work. Maybe because the Label node isn't even in the 3D world?
Would signals help?
P.P.S. sorry if this post has weird formatting. I guess I'm not used to Godot Q&A forum posting.
