[solved]Creating new GUI - Problem with alpha(transparency of my health bar)

[BukkitSmerf]

I trying to create new health bar for my mod. But I can't use alpha ;/

I have my bars.png with transparency bar but in game that just normal color.

 

Anyone know how fix that?

 

 

PS: How to change maxHealth of player?

That red part have some transparency, but in game that just normal red ;/

 

GL11.glColor4f(1.0F, 1.0F, 1.0F, 1.0F);

or any other value like

GL11.glColor4f(1.0F, 1.0F, 1.0F, 0.5F);

don't works good. (some part are still just red, but other have 100% Transparency)

 

 

PS: How about that max hp.

And that possible to scale that GUI in some resolutions? Becouse on small resolution like 1024 x 768 my bar is on hotbar. But in "normal" resolution like: 1280×720 or 1920×1080 is very small ;/

In the one GUI I've built, I've got these lines (and you dont):

 

                GL11.glDisable(GL11.GL_DEPTH_TEST);
                GL11.glDepthMask(false);
                GL11.glBlendFunc(GL11.GL_SRC_ALPHA, GL11.GL_ONE_MINUS_SRC_ALPHA);
                GL11.glColor4f(1.0F, 1.0F, 1.0F, 1.0F);
                GL11.glDisable(GL11.GL_ALPHA_TEST);

                GL11.glDisable(GL11.GL_ALPHA_TEST);

Nope   that also removing alpha. I have just white GUI

I also trying change a few things etc..... but I don't find anything good ;/ Still this same or worse

Make sure belnding is enabled.

GL11.glEnable(GL11.GL_BLEND);

 

And to disable it afterwards:

GL11.glDisable(GL11.GL_BLEND);

 

It might be enabled by default, so I don't know what the problem is if this doesn't help.

sorry for no response I have much to do

THANKS , that fixed all problems.

Just wanted to say thanks to both Glenn and Draco18s - the two posts together is just what I needed to polish off a gui I've been working on.
