Crash log?

 

Container?

 

Also:

Do you know what getPowerScaled() should do? If not, read the TileEntityFurnace code more carefully. You are doing the getPowerScaled() function wrong.

OK, debug the code.

 

I edited the post above, read again.

 

Also this must be added to your container:

To avoid the time and tears later, when you need to sync data between the server and the client

java.lang.NullPointerException: Rendering screen
        at com.camerpon900.realauto2.gui.GuiEnergyCube.drawGuiContainerBackgroundLayer(GuiEnergyCube.java:29)

 

On line 29, there is this code:

int p = this.tileEntityEnergyCube.getPowerScaled(42);

The only thing that can be

null

is

tileEntityEnergyCube

. It your constructor you set that variable, but it stays null. Why? because you call the

GuiEnergyCube

constructor with

tileEntity

being null. So there is an issue with the way you initialize your

GuiEnergyCube

, most likely in your

IGuiHandler

.

thanks i found out what was wrong i set the tile entity to itself instead of the tile entity assigned to the guihandler
