Hello,

I have been working on a custom tool. One of it's properties is that it has a temperature. I have this displayed in the item's tooltip, but I would also like to display it to the player's screen for ease of use. I was recommended to look into the RenderTooltipEvent, but I was unable to find anything in the event or it's sub classes that would actually enable me to accomplish this. Am I looking at the wrong event, or am I simply missing something.

 

 

Thanks in advance!

Okay taking a look at that, that's more along the lines of what I need. However, I now have a problem in that I have no way of getting at the item in the player's inventory. What would I need to call in order to accomplish that?

Okay this is working perfectly. However, I get this cursed image when I run my code:

I've tried calling different drawString variants, but to no avail.

Here is the code I am using:

    @SuppressWarnings("resource")
    @SubscribeEvent
    public static void renderRailgunTooltip(RenderGameOverlayEvent event) {
        
        ItemStack gunStackMainHand = Minecraft.getInstance().player.getItemStackFromSlot(EquipmentSlotType.MAINHAND);
        ItemStack gunStackOffHand = Minecraft.getInstance().player.getItemStackFromSlot(EquipmentSlotType.OFFHAND);
        
        if(gunStackMainHand.getItem() instanceof AbstractRailgun) {
            renderHeatToolTip(event, gunStackMainHand);
        }else if(gunStackOffHand.getItem() instanceof AbstractRailgun) {
            renderHeatToolTip(event, gunStackOffHand);
        }
        
    }

    @SuppressWarnings("static-access")
    private static void renderHeatToolTip(RenderGameOverlayEvent event, ItemStack stack) {
        Minecraft minecraft = Minecraft.getInstance();
        ItemElectric railgun = (ItemElectric)stack.getItem();
        
        ITextComponent text =
            new StringTextComponent("Temperature: " + railgun.getTemperatureStored(stack) + " C").mergeStyle(TextFormatting.YELLOW);
        
        minecraft.currentScreen.
        drawString(event.getMatrixStack(),
            minecraft.fontRenderer, text, text.getString().length(),0,0);
    }
