Help with rendering a GUI

[Big_Bad_E]

I have a simple GUI that's supposed to display a player's armor and a picture of it.

I know I will have problems with Leather Armor cause it's an overlay but I just wanna get basic things working first (Any help doing that would be appriciated)

Here's my code right now:
 

public ArmorOverlay() {
        Minecraft mc = Minecraft.getMinecraft();
        EntityPlayer player = mc.thePlayer;
        for (int i = 0; i < 4; i++) {
            ItemStack armor = player.getCurrentArmor(3-i);
            if (armor != null) {
                String registryName = armor.getItem().getRegistryName();
                mc.renderEngine.bindTexture(new ResourceLocation(registryName.split(":")[0], "textures/items/" + registryName.split(":")[1] + ".png"));
                drawTexturedModalRect(20, 20 + (i * 16), 0, 0, 16, 16);
                drawString(Minecraft.getMinecraft().fontRendererObj, I18n.format(armor.getItem().getUnlocalizedName() + ".name") + " (" + (armor.getMaxDamage() - armor.getItemDamage()) + "/" + armor.getMaxDamage() + ")", 40, 20 + (i * 16), MathHelper.hsvToRGB(Math.max(0.0F, (float) (1.0F - (double) armor.getItemDamage()/ (double) armor.getMaxDamage())) / 3.0F, 1.0F, 1.0F));
            }
        }
    }

My problem is the image won't render, and I think it is a problem with the third and fourth args of the drawTexturedModalRect (I tried getTextureManager too).

The strings draw with the right color, so what's wrong with the armor? If I set the third/fourth args to random things it gives me colored squares.

For a diamond helmet I get blue squares, Leather chestplate gives me green squares, Leather leggings give orange squares, and Diamond boots give me dark green/orange squares

This is called literally once. There are multiple render methods in GuiScreen that are not a constructor.

No it was called multiple times (I was being dumb and created an instance of it in my event)

look at how vanilla does it inside the inventory?

[Big_Bad_E]

Code from GuiCrafting (in the background drawing code)

GlStateManager.color(1.0F, 1.0F, 1.0F, 1.0F);
this.mc.getTextureManager().bindTexture(CRAFTING_TABLE_GUI_TEXTURES);
int i = this.guiLeft;
int j = (this.height - this.ySize) / 2;
this.drawTexturedModalRect(i, j, 0, 0, this.xSize, this.ySize);

Trying that and nothing different.

I tried setting the resource location to "minecraft", "textures/items/diamond_chestplate.png"

and

"minecraft:textures/items/diamond_chestpalte.png"

but it is not working at all.

No not that part, the part that renders the player with all their Armor and held items

Why?

That part renders the GUI, I wanna render a GUI, that looks like the right code.

 

Ohhh, I see what you were thinking.

I am not trying to render the armor model, just the texture.

 

Actually that's a great idea. I'ma do that myself.

Here's the code

GlStateManager.enableColorMaterial();
GlStateManager.pushMatrix();
GlStateManager.translate((float)posX, (float)posY, 50.0F);
GlStateManager.scale((float)(-scale), (float)scale, (float)scale);
GlStateManager.rotate(180.0F, 0.0F, 0.0F, 1.0F);
float f = ent.renderYawOffset;
float f1 = ent.rotationYaw;
float f2 = ent.rotationPitch;
float f3 = ent.prevRotationYawHead;
float f4 = ent.rotationYawHead;
GlStateManager.rotate(135.0F, 0.0F, 1.0F, 0.0F);
RenderHelper.enableStandardItemLighting();
GlStateManager.rotate(-135.0F, 0.0F, 1.0F, 0.0F);
GlStateManager.rotate(-((float)Math.atan((double)(mouseY / 40.0F))) * 20.0F, 1.0F, 0.0F, 0.0F);
ent.renderYawOffset = (float)Math.atan((double)(mouseX / 40.0F)) * 20.0F;
ent.rotationYaw = (float)Math.atan((double)(mouseX / 40.0F)) * 40.0F;
ent.rotationPitch = -((float)Math.atan((double)(mouseY / 40.0F))) * 20.0F;
ent.rotationYawHead = ent.rotationYaw;
ent.prevRotationYawHead = ent.rotationYaw;
GlStateManager.translate(0.0F, 0.0F, 0.0F);
RenderManager rendermanager = Minecraft.getMinecraft().getRenderManager();
rendermanager.setPlayerViewY(180.0F);
rendermanager.setRenderShadow(false);
rendermanager.renderEntity(ent, 0.0D, 0.0D, 0.0D, 0.0F, 1.0F, false);
rendermanager.setRenderShadow(true);
ent.renderYawOffset = f;
ent.rotationYaw = f1;
ent.rotationPitch = f2;
ent.prevRotationYawHead = f3;
ent.rotationYawHead = f4;
GlStateManager.popMatrix();
RenderHelper.disableStandardItemLighting();
GlStateManager.disableRescaleNormal();
GlStateManager.setActiveTexture(OpenGlHelper.lightmapTexUnit);
GlStateManager.disableTexture2D();
GlStateManager.setActiveTexture(OpenGlHelper.defaultTexUnit);

I think it's looking really cool

Needs some refining but thanks for the idea Cadiboo!

 

Quick question, what is the variable for the direction the player's body is facing? Also is it possible to disable a player's death animation?

If your just trying to render the armor ItemStack model then have a look at

https://github.com/Cadiboo/WIPTech/blob/d5504c15d23c66b220064c93ce8fa27c3c457fd0/src/main/java/cadiboo/wiptech/client/gui/GuiAssemblyTable.java#L112-L178

and

https://github.com/Cadiboo/WIPTechAlpha/blob/41c881e00fa7a309761aeeea944dc552fec3fa30/src/main/java/cadiboo/wiptech/client/ClientUtil.java#L634-L746

the variable for the players facing direction player.rotationYaw & player.rotationPitch. you may have to use some 3d math / trigonometry to get the actual position.

You could probably disable the death animation, but it would require digging into the source code to find out where the death animation is actually done.

If you do decide to try and do this have a look at 

RenderLivingBase [line: 285] - setBrightness(T, float, boolean)    
RenderLivingBase [line: 414] - applyRotations(T, float, float, float)    
RenderPlayer [line: 254] - applyRotations(AbstractClientPlayer, float, float, float)

Here is my code:

        for (int i = 0; i < 4; i++) {
            ItemStack itemArmor = Minecraft.getMinecraft().thePlayer.getCurrentArmor(i);
            if (itemArmor != null)
                armor.add(itemArmor);
        }
    }

    public void render() {
        if (Minecraft.getMinecraft().thePlayer.isDead) return;
        List<ItemStack> newArmor = new ArrayList<ItemStack>();
        for (int i = 0; i < 4; i++) {
            ItemStack itemArmor = Minecraft.getMinecraft().thePlayer.getCurrentArmor(i);
            if (itemArmor != null)
                newArmor.add(itemArmor);
        }
        if (!armor.equals(newArmor)) {
            renderEntity();
            for (int i = 0; i < 4; i++) {
                ItemStack armor = Minecraft.getMinecraft().thePlayer.getCurrentArmor(3 - i);

            e.printStackTrace();
        }
    }
}

For some reason the player's body will turn instead of staying the same like it should.

Also the player will vibrate around whenever I move.

And, the player's head's pitch is not working for some reason.

I tried setting lastPosX/Y and no luck.

Well that's a weird glitch.

Minecraft drugs mod coming soon!

You obviously forgot to zero out the player's position before rendering.
