[1.7.10] Making in hand items & armor opaque?

[Crow]

I have created some glass like armor and would like to have the item and armor opaque when wearing it and when holding it.

Don't really know how to go about this. Any ideas? Thanks.

Hi

 

You mean transparent some of the time, and opaque the rest of the time?

 

Do you know how to use blending and alpha values?

 

Minecraft generally uses

 

            GL11.glEnable(GL11.GL_BLEND);

            GL11.glBlendFunc(GL11.GL_SRC_ALPHA, GL11.GL_ONE_MINUS_SRC_ALPHA);

and

 

            GL11.glDisable(GL11.GL_BLEND);

 

If you're going to change these modes, it's a good idea to wrap it in

 

try {

      GL11.glPushAttrib(GL11.GL_ENABLE_BIT);  // save the current modes

 

  // change modes here, do your rendering

 

} finally {

      GL11.glPopAttrib();  // restore the previous modes

}

 

What does your armor rendering code currently look like?

Best way to describe what I am wanting is like stained glass. How the item is opaque in your hand and when placed.

I am wanting the armor item to be opaque and armor when worn.

 

Just basic armor class

public class ooArmor extends ItemArmor 
{
public String texture;

public ooArmor(ArmorMaterial mat, String texture, String name, int index, int type) {
	super(mat, index, type);
	this.setUnlocalizedName(name);
	this.texture = texture;
	this.
	this.setCreativeTab(OreOverhaul.tabOreOverhaul);

	GameRegistry.registerItem(this, this.getUnlocalizedName().substring(5));
}

@SideOnly(Side.CLIENT)
public void registerIcons(IIconRegister iconRegister)
{
	this.itemIcon = iconRegister.registerIcon(OreOverhaul.modid + ":" + this.getUnlocalizedName().substring(5));
}

@Override
public String getArmorTexture(ItemStack stack, Entity entity, int slot, String type)
{
	if(this.armorType == 2)
	{
		return "oreoverhaul:textures/models/armor/" + this.texture + "2.png";
	}

	return "oreoverhaul:textures/models/armor/" + this.texture + "1.png";

}

}

I have opaque armor item textures and both model textures made already, they're just not opaque in the game.

Hi

 

Could you show some screenshots - how your model should look, and how it actually looks?

 

I'm not sure we both have the same meaning of the word "opaque"

What it looks like now

 

 

What I need it to look like

 

armor item the same.

[Crow]

I guess translucent would be a better word...

[TheGreyGhost]

OK, I get it now; yeah translucent or semi-opaque or partially transparent.

 

Anyway, I have to admit I'm not sure.

 

The armor rendering code is based in RendererLivingEntity.doRender, in this bit

            for (int i = 0; i < 4; ++i)
            {
                j = this.shouldRenderPass(p_76986_1_, i, p_76986_9_);

                if (j > 0)
                {
                    this.renderPassModel.setLivingAnimations(p_76986_1_, f7, f6, p_76986_9_);
                    this.renderPassModel.render(p_76986_1_, f7, f6, f4, f3 - f2, f13, f5);

                    if ((j & 240) == 16)
                    {
                        this.func_82408_c(p_76986_1_, i, p_76986_9_);
                        this.renderPassModel.render(p_76986_1_, f7, f6, f4, f3 - f2, f13, f5);
                    }

                    if ((j & 15) == 15)
// etc

and in particular,

shouldRenderPass calls your getArmorTexture with type set to null, and then

func_82408_c calls your getArmorTexture with type set to "overlay"  i.e.

public String getArmorTexture(ItemStack stack, Entity entity, int slot, String type)

 

shouldRenderPass() is misleading name by the way.  It iterates through each piece of armour and returns flags for whether it's coloured, has an overlay, and whether it has a magical glint.

 

You could perhaps try turning on the blend function GL11.glEnable(GL11.GL_BLEND); in your getArmorTexture (null).  But that might make any other armor items look a bit odd, unless you turn if off again in getArmorTexture("overlay"), which means your armour type would have to be cloth (getColor returns -1).

 

It's a bit of a hack but it might work:

 

            for (int i = 0; i < 4; ++i)
            {
                j = this.shouldRenderPass(p_76986_1_, i, p_76986_9_);  // calls getArmorTexture(null)  ... GL11.glEnable(GL11.GL_BLEND) in here
                                                                                                    // returns 16 or 31 because getColor returns -1  

                if (j > 0)
                {
                    this.renderPassModel.setLivingAnimations(p_76986_1_, f7, f6, p_76986_9_);
                    this.renderPassModel.render(p_76986_1_, f7, f6, f4, f3 - f2, f13, f5);               // render your translucent armour

                    if ((j & 240) == 16)
                    {
                        this.func_82408_c(p_76986_1_, i, p_76986_9_);                                       // calls getArmorTexture("overlay")  ... GL11.glDisable(GL11.GL_BLEND) in here
                                                                                                                                      // return a fully transparent texture so nothing is drawn
                        this.renderPassModel.render(p_76986_1_, f7, f6, f4, f3 - f2, f13, f5);         
                    }

                    if ((j & 15) == 15)
// etc

Think I just got a really close buzz cut from all that flying over my head.. lol

Might be a little much for me at my current skill level..

[TheGreyGhost]

ROFL

 

well to be honest it might crash and burn for all I know, never tried it and I'm just making it up on the fly..

 

If it's any consolation I think your armour looks good opaque anyhow.

[Crow]

Lol.. That armor is kinda just my place holder armor to see if I could get it translucent.

Trust me the 40ish other sets look 100x better than that. lol

 

Got another question. I made a set of redstone armor and thought it would be cool if it could have a particle effect and

dimmly light up the surrounding area when worn. Like when you hit/walkover a redstone ore. Got any pointers for that?
