[1.12.2][GUI] Popup text element when hovered over a GUI location

[Lambda]

Hello!

 

So my block needs water to run (ex. raining/water buckets, etc) and I have a popup next to the gui inventory that shows that it needs one:

 

I want it to have the functionality for when you hover over it, it creates a text box saying "Needs water!" or something like that. I want the text box to be similar to the ones found when you hover over an item.

 

Thank you!

The issue has not actually been solved

Yes I found this function, however is there a method to detect where the mouse is and display the hover box when its only over that area?

[Draco18s]

Buttons do this already. Just make that area a button.

Okay, and how do I set the button to not "highlight" itself and set the texture to what I have it as now?

Take a look at what I did

Ah perfect! Thanks for that!

Okay, so I got the button half working. Its there and it clicks, but no hovering text. Aswell, how would I make the button go away when x condition is met:

 

Here is what I have so far:

@SideOnly(Side.CLIENT)
public class GuiVoidInfuser extends GuiContainerMod {

	private static final ResourceLocation RES_LOC = ResourceUtil.getGuiLocation("gui_voidInfuser");

    private final TileEntityVoidInfuser tileVoidInfuser;
    public static GuiVoidInfuser self;
        
    private float tickTime;
    private HintButton needsWater;
	
    public GuiVoidInfuser(InventoryPlayer inventoryPlayer, TileEntityBase tile){
        this(inventoryPlayer, tile, false);
    }

    private GuiVoidInfuser(InventoryPlayer inventory, TileEntityBase tile, boolean isDouble){
        super(new ContainerVoidInfuser(inventory, tile));
        this.tileVoidInfuser = (TileEntityVoidInfuser)tile;
        this.xSize = 176;
        this.ySize = 179;
        self = this;
    }

    @Override
    public void initGui(){
        super.initGui();
        
        this.needsWater = new HintButton(0, this.guiLeft+148, this.guiTop+42);
       	this.buttonList.add(this.needsWater);
    }
    
    @Override
    public void updateScreen(){
        super.updateScreen();
    }
    
    @Override
    public void drawScreen(int x, int y, float f){
        super.drawScreen(x, y, f);
    }

    @Override
    public void drawGuiContainerForegroundLayer(int x, int y){
        ResourceUtil.displayNameString(this.fontRenderer, this.xSize, -10, this.tileVoidInfuser);
    }
    
    @Override
    public void drawGuiContainerBackgroundLayer(float f, int x, int y){
        GlStateManager.color(1.0F, 1.0F, 1.0F, 1.0F);

        this.mc.getTextureManager().bindTexture(ResourceUtil.GUI_INVENTORY_LOCATION);
        this.drawTexturedModalRect(this.guiLeft, this.guiTop+93, 0, 0, 176, 86);
        
        this.mc.getTextureManager().bindTexture(RES_LOC);
        this.drawTexturedModalRect(this.guiLeft, this.guiTop, 0, 0, 176, 93);
        
        if(this.tileVoidInfuser.hasWater == false){
            this.drawTexturedModalRect(this.guiLeft+148, this.guiTop+42, 180, 0, 19, 18);
        }else {
            this.tickTime = (55.00F / (float)this.tileVoidInfuser.runtime) * 100.00F; //55 ticks being MOST efficient
            this.fontRenderer.drawString((int)(this.tickTime) + "%", this.guiLeft+142, this.guiTop+75, StringUtil.COLOR_WHITE);
        }
    }
    
    public void drawText(List text, int x, int y) {
    	this.drawHoveringText(text, x, y);
    }
    
    @SideOnly(Side.CLIENT)
	static class HintButton extends GuiButton {

		protected HintButton(int buttonID, int posx, int posy) {
			super(buttonID, posx, posy, 18, 19, "");
		}

		@Override
		public void drawButton(Minecraft mc, int mouseX, int mouseY, float partialTicks) {
			if (this.visible) {
				mc.getTextureManager().bindTexture(RES_LOC);
				GL11.glColor4f(1.0F, 1.0F, 1.0F, 1.0F);
				this.hovered = mouseX >= this.x && mouseY >= this.y && mouseX < this.x + this.width && mouseY < this.y + this.height;
				this.drawTexturedModalRect(this.x, this.y, 0, 182, this.width, this.height);
			}
		}

		@Override
		public void drawButtonForegroundLayer(int x, int y) {
			List list = new ArrayList<String>();
			list.add(I18n.format("ce:voidIF_water"));
			GuiVoidInfuser.self.drawText(list, x, y);
		}
	}
    
}

 

It follows your code's basic principal and it still doesn't work; as well, what I mean by condition x is this:

        if(this.tileVoidInfuser.hasWater == false){
            this.drawTexturedModalRect(this.guiLeft+148, this.guiTop+42, 180, 0, 19, 18);
        }else {
            this.tickTime = (55.00F / (float)this.tileVoidInfuser.runtime) * 100.00F; //55 ticks being MOST efficient
            this.fontRenderer.drawString((int)(this.tickTime) + "%", this.guiLeft+142, this.guiTop+75, StringUtil.COLOR_WHITE);
        }

If hasWater is false, it displays that little icon -- I want the button to also appear/disappear with that.

 

Thanks

 

-- Nevermind! I found my error, I didn't iterate through the ubttons to check if the mouse is over!

 

Thanks for my help.

and this is the fix:

Spoiler

		Iterator<GuiButton> iterator = this.buttonList.iterator();

		while (iterator.hasNext())
		{
			GuiButton guibutton = iterator.next();

			if (guibutton.isMouseOver())
			{
				guibutton.drawButtonForegroundLayer(x- this.guiLeft, y - this.guiTop);
				break;
			}
		}
