I am following the guide for huds for noobs on the wiki:
http://www.jmonkeyengine.com/wiki/doku.php?id=displaying_dynamic_values_in_the_hud
And it was going good until this article.
I am using JME 2.0 and it seems to be complaining about lines where i use :
.setTextureBuffer(FloatBuffer,int)
could be that this functionen doesnt exist or is named different in jme2 cause this tutorial refers to jme1
When Making the hud it could be easier to use feng gui this how i do it with jme1
I think the problem is that TriangleBatch-s were removed in jME 1 -> jME 2. Try .setTextureCoords()
When you find yourelf in a similar situation in the future, one easy way to find out how to change your code from jME 1 to jME 2 is by doing a search in the source:
batch.setTextureBuffer(BufferUtils.createVector2Buffer(geometryBatchCreator.getNumVertices()), 0);
mesh.setTextureCoords(new TexCoords(BufferUtils.createVector2Buffer(geometryBatchCreator.getNumVertices())), 0);
I'll add it to the wiki
help!
I cvhanged my code to conform to the snippet you posted. Now the bar appears in magenta, however nothing moves in the bar …
Even when I move the camera…
It probably did not find the texture file hudtutorial3.png. Make sure it is available for your code. Te pink tex you see is the default texture. If you look at the output on the console it will probably also tell you that this problem occurred.
thanks, however, thepic in the tutorial is huge, and seems to have 2 images in it, is this the correct hudtutorial3.png?
the image linked to from the tutorial works fine
for some reason it isnt being loaded properly on my end, you are talking about this :
http://www.jmonkeyengine.com/wiki/lib/exe/detail.php?id=displaying_dynamic_values_in_the_hud&cache=cache&media=hudtutorial3.png
if you look at that png, it has all sorts of rubbish in it :S
the image consists of two parts the gauge and the border, texture coordinates are used to display the correct parts when needed.
in the Buster class you have this:
hudNode.setLocalTranslation(new Vector3f(this.getLocalTranslation().x,
this.getLocalTranslation().y+100,
this.getLocalTranslation().z));
oh…
hmmm…
I tried searching for them, but dont see them

am using the textlabel2d class, and it if works, ill make it work with the healthbar (will be similar no doubt) Thanks core.

anybody help!

It is because createTextureBuffer isnt used, its now createTextureCoords, but i dont know how to change the bits of code!
Please! Somebody!
see my earlier reply, you cannot use the location of your enemy to set the location of the HP Bar.
Those two objects use different coordinate systems.
this would only work if the Buster is rendered in ORTHO Queue which, i guess, isn't.
hudNode.setLocalTranslation(new Vector3f(this.getLocalTranslation().x,this.getLocalTranslation().y+100,this.getLocalTranslation().z));
argh yes - so how DO i do it then!? in reference to my example code!
