Setting String in TileEntity from GuiContainer

[jaswon5791]

The situation is as follows: I've created a furnace-esque block called a Write Drive, and in the GUI I have a GuiTextField, and I want to set a string in the TileEntity object to the contents of this GuiTextField. Here is the relevant code:

 

GuiWriteDrive.java:

 

public class GuiWriteDrive extends GuiContainer {

public static final ResourceLocation bground = new ResourceLocation(ModInfo.ID.toLowerCase(),"textures/gui/furnace.png");

private GuiTextField path;

public TileEntityWriteDrive writeDrive;
private TileEntityWriteDrive tile;

public GuiWriteDrive(InventoryPlayer invPlayer, TileEntityWriteDrive entity) {
	super(new ContainerWriteDrive(invPlayer, entity));
	this.writeDrive = entity;
	this.xSize = 176;
	this.ySize = 166;
}

public void drawGuiContainerForegroundLayer(int par1, int par2) {
	String name = this.writeDrive.hasCustomInventoryName() ? this.writeDrive.getInventoryName() : I18n.format(this.writeDrive.getInventoryName(), new Object[0]);
	this.fontRendererObj.drawString(name, (this.xSize - this.fontRendererObj.getStringWidth(name))/2, 6, 4210752);
}

@Override
protected void drawGuiContainerBackgroundLayer(float f, int j, int i) {
	GL11.glColor4f(1F, 1F, 1F, 1F);
	Minecraft.getMinecraft().getTextureManager().bindTexture(bground);
	drawTexturedModalRect(guiLeft, guiTop, 0, 0, xSize, ySize);
	if (writeDrive.isCooking())
	{
		int j1 = writeDrive.getCookTimeRemainingScaled(24);
		drawTexturedModalRect(guiLeft + 78, guiTop + 39, 176, 14, j1 , 17);
	}
	if (writeDrive.isBurning()) {
		int j2 = writeDrive.getBurnTimeRemainingScaled(35);
		drawTexturedModalRect(guiLeft + 27, guiTop + 69, 176, 0, j2 , 7);
	}
}

@Override
    public void drawScreen(int par1, int par2, float par3)
    {
        super.drawScreen(par1, par2, par3);
        this.path.drawTextBox();
    }

public void initGui()
    {
    	super.initGui();
    	this.path = new GuiTextField(this.fontRendererObj,  guiLeft + 6, guiTop + 40, 67, 13);
    	this.path.setTextColor(-1);
    	this.path.setDisabledTextColour(-1);
        this.path.setEnableBackgroundDrawing(true);
        this.path.setMaxStringLength(40);
        this.path.setFocused(true);
    }

public void keyTyped(char c, int i){
	this.path.textboxKeyTyped(c, i);
	TileEntityWriteDrive tile = (TileEntityWriteDrive) writeDrive.getWorldObj().getTileEntity(writeDrive.xCoord, writeDrive.yCoord, writeDrive.zCoord);
	if (tile != null) {
    		tile.path = this.path.getText();
    	}
        if(!( i == Keyboard.KEY_E  &&  this.path.isFocused())) super.keyTyped(c, i);
}
protected void mouseClicked(int par1, int par2, int par3)
    {
        super.mouseClicked(par1, par2, par3);
        this.path.mouseClicked(par1, par2, par3);
    }

public void updateScreen()
    {
        this.path.updateCursorCounter();
    }

}

 

TileEntityWriteDrive.java:

 

public class TileEntityWriteDrive extends TileEntity implements IInventory {

private String local;

private ItemStack[] slots;

public int burnTime;
public int currentItemBurnTime;
public int cookTime;

	burnTime = 0;

}

@Override

		}
	}
	compound.setTag("ItemsWriteDrive", list);
	compound.setString("path", path);

public boolean canWrite() {

	 {

	 }
	 else if (Item.getIdFromItem(slots[2].getItem()) == Item.getIdFromItem(itemstack.getItem()))
	 {
		 slots[2].stackSize++;
	 }
	 for (int i = 0; i < 2; i++)
	 {
		 if (slots[i].stackSize <= 0)
		 {
			 slots[i] = new ItemStack(slots[i].getItem().setFull3D());
		 }
		 else
		 {
			 slots[i].stackSize--;
		 }
		 if (slots[i].stackSize <= 0)
		 {
			 slots[i] = null;
		 }
	 }
}
public void updateEntity()
{
	 boolean flag = burnTime > 0;
	 boolean flag1 = false;
	 if (burnTime > 0)
	 {

}

 

What's supposed to happen is that every time a key is pressed within the Gui, tile.path should be set to the contents of the textfield, but that's not actually working. keyTyped() is firing every time I press a key, getText() correctly returns the contents of the textfield, tile does not return null, but for some reason the sysout I have in the first line of the canWrite() method keeps showing "path = " i.e. path wasn't set by the Gui. Can someone lead me in the right direction? I'm pretty sure it's either something really wrong with my code or a typo, but I can't find anything on the internet.

need to use packets to set it for you, you can look at how I do it

https://github.com/Hugo-the-Dwarf/Rise-of-Tristram/blob/master/src/main/java/ee/rot/gui/GuiMagicBase.java

I'm assuming you're talking about this line (and a few others):

 

Rot.net.sendToServer(new BaseBuilderPacket("2;"+te.xCoord+","+te.yCoord+","+te.zCoord));

 

I found the BaseBuilderPacket class, as well as the TextPacket class, and the method call makes it clear what you're doing. However, I couldn't find the actual code for Rot.net.sendToServer, could you please elaborate on this part?

 

edit:

 

I actually just found that Rot.net refers to a SimpleNetworkWrapper object within your main mod file. I'll look into this, thank you for the resources!

[hugo_the_dwarf]

@Override

protected void actionPerformed(GuiButton button)

{

 

I then check to see if the button ID is my send list button, if so. Send a packet to the server Rot.net.sendToServer(new BaseBuilderPacket("0;"+te.xCoord+","+te.yCoord+","+te.zCoord+";"+list[listIndex++]));

 

now of course you don't need all of what I sent and how I did it, you can use ints for the tile entity coords I kinda derped when making the packet (used to web based stuff and turning everything into a string and decomplining it at the other end.) but the idea of GUI to server to tileEntity is there

I got it to work! Thank you so much for your help
