La déclaration des tabs (dans la classe principale) :

public static ElementalCreativeTab etypes = new ElementalCreativeTab("elementalTypes", itemTypeSwitcher);
    public static ElementalCreativeTab eTools = new ElementalCreativeTab("elementalTools", swordOldSnow);
    public static ElementalCreativeTab eUtils = new ElementalCreativeTab("elementalUtils", Item.getItemFromBlock(blockPurifier));

Et la classe ElementalCreativeTab.java :

public class ElementalCreativeTab extends CreativeTabs {
    private Item icon;

    public ElementalCreativeTab(String label, Item icon) {
        super(label);
        this.icon = icon;
    }

    @SideOnly(Side.CLIENT)
    public Item getTabIconItem() {
        return icon;
    }
}

Problème d'overlay

J'ai donc aussi un problème d'overlay. J'ai une texture de barre de progression verticale mais cela affiche un truc bizarre à la place.
Screens :
0_1537628787598_2015-11-11_14.56.05.png

Ma classe d'overlay :

public class PowerOverlay extends Gui {

    public static PowerOverlay instance;
    private boolean showing = true;

    public PowerOverlay() {
        instance = this;
    }

    @SubscribeEvent
    public void renderElementalPower(RenderGameOverlayEvent e) {
        if(e.isCancelable() || e.type != ElementType.EXPERIENCE || !showing) {
            return;
        }
        int xSize = 16;
        int ySize = 128;
        int x = e.resolution.getScaledWidth() - 24;
        int y = e.resolution.getScaledHeight() / 2 - 64;
        int ytext = e.resolution.getScaledHeight() / 2 + 72;
        Minecraft mc = Minecraft.getMinecraft();
        ResourceLocation texture = new ResourceLocation("elementalmod", "textures/gui/elementalpower.png");

        GL11.glColor4f(1.0F, 1.0F, 1.0F, 1.0F);
        mc.getTextureManager().bindTexture(texture);
        drawTexturedModalRect(x, y, 0, 0, xSize, ySize);

        int power = ElementalExtendedProperties.get(mc.thePlayer).getMana();
        int maxpower = ElementalExtendedProperties.get(mc.thePlayer).getMaxMana();
        String type = types[ElementalExtendedProperties.get(mc.thePlayer).getType()];
        int i = (int) power / maxpower * ySize;
           //drawTexturedModalRect(x, y, 16, 0, xSize, i);
           drawCenteredString(mc.fontRendererObj, type, x + xSize / 2, ytext, new Color(200, 200, 200).getRGB());
    }

    public boolean isShowing() {
        return showing;
    }

    public void setShowing(boolean show) {
        showing = show;
    }
}

Merci d'avance pour votre aide !

tu as un npe, à mon avis c'est l'item qui doit être utilisé pour l'affichage qui est null.
ta texture devrait faire 256x256 et ensuite dans la méthode draw tu dois spécifier à quel endroit elle se trouve dans le fichier.
