Trying reflection for the first time, and something which seemed very simple eludes me.

 

if (rider != null && rider.ridingEntity != null) {
			if (rider.getHeldItem() != null && rider.getHeldItem().isItemEqual(new ItemStack(Items.carrot_on_a_stick))) {
				System.out.println("Rider is holding carrot on a stick.");
				Class clazz = EntityPig.class;
				Method method = null;
				try {
					method = clazz.getMethod("updateAITasks", (Class) null);
				} catch (NoSuchMethodException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				} catch (SecurityException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				}

				if (method != null) {
					try {
						method.invoke(pig, (Class) null);
					} catch (IllegalAccessException e) {
						// TODO Auto-generated catch block
						e.printStackTrace();
					} catch (IllegalArgumentException e) {
						// TODO Auto-generated catch block
						e.printStackTrace();
					} catch (InvocationTargetException e) {
						// TODO Auto-generated catch block
						e.printStackTrace();
					}

					System.out.println("Success!");
				}
			}
			System.out.println("CheckRiderThread: ridingEntity set.");
		}
	}

 

Here is the corresponding method I am trying to access from EntityPig:

protected void updateAITasks()
    {
        super.updateAITasks();
    }

 

So, why is it throwing a NoSuchMethodException when I try to access the method?

Your class.getMethod() call has too many parameters. Remove "(Class) null"

Still doesn't work.

 

if (rider != null && rider.ridingEntity != null) {
			if (rider.getHeldItem() != null && rider.getHeldItem().isItemEqual(new ItemStack(Items.carrot_on_a_stick))) {
				System.out.println("Rider is holding carrot on a stick.");
				Class clazz = EntityPig.class;
				Method method = null;
				try {
					method = clazz.getMethod("updateAITasks");
				} catch (NoSuchMethodException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				} catch (SecurityException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				}

				if (method != null) {
					try {
						method.invoke(pig);
					} catch (IllegalAccessException e) {
						// TODO Auto-generated catch block
						e.printStackTrace();
					} catch (IllegalArgumentException e) {
						// TODO Auto-generated catch block
						e.printStackTrace();
					} catch (InvocationTargetException e) {
						// TODO Auto-generated catch block
						e.printStackTrace();
					}

					System.out.println("Success!");
				}
			}
			System.out.println("CheckRiderThread: ridingEntity set.");
		}
	}

 

@diesieben: If you join the game on a mounted pig and are holding a carrot on a stick, you have to wait a significant amount of time before it registers and the pig starts walking. I'm attempting to eliminate the wait time.

How do I set it to accessible if I can't access it in the first place?

 

Edit: Nevermind, figured it out. I got the method to fire but unfortunately it didn't do anything. Thanks anyway, though.
