This is my first time trying to make a gui, and i'm not quite sure how to go about it. I want to add a gui to my proximity detector so that the range and functions can be changed. I've already set up the fields i feel will be necessary in the TileEntity, which is currently working as expected.

I tried looking through the tutorial on the wiki which didn't really help with what i want to do (as far as i could tell) and didn't explain it in a way which made it so i could understand everything which was going on.

 

I need buttons so that i can change the entity types it will detect, and also the range on the detector. If somebody could walk me through the basics of this that would be great

If you want to learn about guis I advice you to follow this guy

 

http://www.youtube.com/user/DiedGaming5049/videos

 

I have no information on guis but this guy is helpful alot at least for me

This might be able to help:

If you want to make a GUI and a tile entity without an inventory, you'll be needing the following classes.

 

A block

A GUI handler

A GUI class for the block

A tile entity class

A packet handler

 

Here are those 4 classes from one of my mods (the block is called NumpadBlock):

 

NumpadBlock class:

        	return false;
        	        	
        }

        par5EntityPlayer.openGui(Interlock.instance, 2, world, x, y, z);
        
        return true;
        
    }

    /**
     * If this returns true, then comparators facing away from this block will use the value from

    }

     * If hasComparatorInputOverride returns true, the return value from this is used instead of the redstone signal
     * strength when this block inputs to a comparator.

    {
        return 0;

If you have experience with forge modding, you'll probably understand what's going on in each file, if not, just ask

just another small question,

 

what do i need to send packets for (and how do i do/handle this properly)? I'm trying to do it so that the range, and detection types in my proximity detector can be changed, so do i need to send a packet each time one of these buttons is pressed, and also how do i send and use the data on the button?

 

also, where is the id for the gui defined? in the following line form your code it is called, but i can't see where it is created or how to know what it will be.

 

par5EntityPlayer.openGui(Interlock.instance, 2, world, x, y, z);

 

[EDIT]

Also, can i see how you registered your package handlers and channels, doing it in the same way as the wiki tutorial gave me a crash saying that the channel name was incorrect or something.
