it only shows in the player's hand and not inside the inventory or in a chest etc... how do i do that? this is the code used for the item texture in my item class:

public void registerIcons(IIconRegister iconReg)
{
	this.itemIcon = iconReg.registerIcon("something");
	this.itemIcon2= iconReg.registerIcon("something");
}

public IIcon getIcon(ItemStack itemstack, int pass)
{
	if(itemstack.stackTagCompound.getInteger("Timer") > 0)
	{
		return this.itemIcon2;
	}
	else
	{
		return this.itemIcon;
	}
}

public IIcon getIcon(ItemStack itemstack, int pass)

 

Is a method called by renderers that update equipped items.

 

You have to use this:

public IIcon getIconIndex(ItemStack itemstack)

To set the icon in inventories, you need to set itemIcon instance variable, also you may need to save your first icon as "itemIcon1" or else you will lose it when you switch to the second icon. Try this:

public void registerIcons(IIconRegister iconReg) {
	this.itemIcon1 = iconReg.registerIcon("something");
	this.itemIcon2= iconReg.registerIcon("something");
}

public IIcon getIcon(ItemStack itemstack, int pass) {
	if(itemstack.stackTagCompound.getInteger("Timer") > 0) {
		this.itemIcon = itemIcon2;
		return this.itemIcon2;
	} else {
		this.itemIcon = itemIcon1;
		return this.itemIcon1;
	}
}
