I Need some help for GUI task…
What I want to achieve is I want to have a popup menu whenever I see an object long enough.
But I want this menu to be separate from the GUI node as to select the menu I Need to look at it again.
I tried using Picture object but doesnt seem to work.
Then I tried using Spatial but apparently I cant find the right coordinate to place it at the Scene.
It has to be relative to my view (1st Person view), but when I attach Spatial it will be relative to root node…
as I am not entirely sure I got the question, I might be off, but here my idea:
Shoot a ray, find the first collision, get the spatials coordinates, attach your “bubble” or what ever to the rootNode and move it above the found spatial?
The problem will be the rotation of the box (I want to display a button so I figure I should create a box).
This box will not always face to my direction.
As I am flying I might be above the Scene or could be just standing on the Scene.
Also I find it hard to determine the x and y coordinate as I could be everywhere (But I want the box to always appear near the centre of my view).
give it a CustomControl (box.addControl(myControl); )
and have it rotate towards you in the update loop. Not sure if it’s the best idea, but at least it should be working
in case you don’t know how to do this:
use on the spatial the lookAt method, enter the cam position
While I’m not exactly sure what you mean by center of your view … sounds like attaching to the guiNode to me?
Yes it would be easier if I could attached it to the guiNode, but if I do that, the box(button) will be moving along with me when I am moving.
After the button shows up I want it to stay there so I can select it with my crosshair.
then I think the method I explained earlier should do the trick?
Check if you hit the right spatial (+time) - if the conditions are met, you add the button to the scene, looking at the camera? so it stays there and you may select a menu item.
So the only thing left is when you look neither on menu nor spatial, to make it disappear. Done.
This actually great at last I have progress!
But it’s not exactly accurate, so I did this
[java]mlButton.lookAt(cam.getDirection(), new Vector3f(0, 1, 0));
[/java]
But it is not always face to camera.
