Basically, I'm trying to determine if the entity the player is currently looking at is a horse.  Does this sound about right?

@SubscribeEvent
public void isHorse(RenderGameOverlayEvent.Text event)
{
	Minecraft mc = Minecraft.getMinecraft();

	If(mc.gameSettings.showDebugInfo)
		if(mc.objectMouseOver != null && mc.objectMouseOver.entityHit instanceof EntityHorse)
		{
			//Do stuff if it's a horse
		}
}

 

Does it work?

Nope, not at all -.-

I added some logger bits to help debug.  It doesn't seem to be registering when it enters the debug screen.  The horse stuff might actually work, but it doesn't seem to be even getting that far.  It should be listening for the RenderGameOverlayEvent, when text is drawn on the screen, and check if it's the debug info being shown.

 

    @SideOnly(Side.CLIENT)
    @SubscribeEvent
    public void onLookHorse(RenderGameOverlayEvent.Text event)
    {
        Minecraft mc = Minecraft.getMinecraft();
        EntityPlayer player = Minecraft.getMinecraft().player;

        if(mc.gameSettings.showDebugInfo)
        {
            logger.info("Debug screen successfully entered..");
            if(mc.objectMouseOver != null && mc.objectMouseOver.entityHit instanceof EntityHorse )
            {
                logger.info("objectMouseOver is a horse..");
                getHorseInfo(event, player, (EntityHorse)mc.objectMouseOver.entityHit);
            }
        }
    }

 

logger.info("Is debug enabled? " + mc.gameSettings.showDebugInfo);

I added that just after where I declared my mc and player variables, just before entering the first if statement.  Nothing happened still.  It's like it isn't even subscribing to the RenderGameOverlayEvent.Text properly.

Or I could be an idiot and realize it isn't even loading the mod when I run the client in IntelliJ..

I forgot to add

@net.minecraftforge.fml.common.Mod

just before the public class HorseInfo   Anyway, it does seem to work.
