After i finally got my dimension working i started to add some fancy feature to my mod (plants, more blocks...) and now i want to add a gui to one of my main Blocks. So I created a TileEntity, a GuiHandler, a Container and, big surprise, it worked :) ...first.  Then i saw the endereye that was placed in the upper slot and the enderpearl in the bottom one.  :'(

 

(This is what my gui looks like:)

My goal is to get energy from the items in the bottom slots in my energy var. Right now the energy simply keeps increasing (even if i take out the pregenerated enderpearl) and if i try to take out the endereye my game crashes.

 

 

Now going to open gui

Hey,

 

Your problem is that you are initializing your inventory slots to your fuel list which is what is giving you your error.

 

Change:

 

private ItemStack[] slots=getFuels();

to

  private ItemStack[] slots= new ItemStack[iNVENTORY_SIZE];

 

Not only that but your ItemStack[] for your fuels list is initialized to two item stacks and not the entire fuel list.

 

Change:

 

private ItemStack[] fuel=new ItemStack[]{new ItemStack(Items.ender_pearl), new ItemStack(Items.ender_eye)};

to

private ItemStack[] fuel=getFuels();

 

Along with that in your Container you have the top slot in your gui mapped to slot 0 and the bottom one mapped to slot 1, not sure if this is a bug but that is how it is.

EDIT: Ok now i tried to add:

@SideOnly(Side.CLIENT)
public int getDimensionEnergyScaled(int heightDimensionEnergyBar) { 
    	int res = this.dimensionEnergy * heightDimensionEnergyBar / this.requiredDimensionEnergy;
    	System.out.println("resscaled is:  dimensionEnergy(" + this.dimensionEnergy + ") * heightDimensionEneryBar(" + heightDimensionEnergyBar + ") / this.requiredDimensionEnergy(" + this.requiredDimensionEnergy + ")");
	return res;
}

 

and it looks like my dimensionEnergy(new name for energy) i never really set (According to output it is 0) but my onupdatething says that it is increasing.

Not sure whats i have done wrong...

 

 

And have i done something wrong in my lang file?

 

tried to add "container.simpleController.name=Simple Controller" but the name still is container.simpleController.
