I'm trying to get it so that the movement keys control the movement of my custom entity, I already looked at the boat and pig code but I couldn't get it to work.

It's great that you're trying so many things, but it is important to go through a few steps before asking for help.

 

For example don't just say "it doesn't work". What exactly doesn't work? Did you trace the code execution to see where it is failing? Does the code for the entity being ridden show that it "knows" that it is being ridden? Do you see the code related to movement properly switching to the ridden entity.

 

Without knowing this we will just say "copy the code for riding a pig"...

 

Basically, always trace your code to figure out where exactly it is failing, then if you can't figure out what is wrong, post the specific description along with the code.

I've attached the entity code. How do I make my code work so that the player can control it.

Before talking about this specific problem, your code has another problem. You're calling the Minecraft class (where you set the view entity) from a common class. This will cause crashes on a dedicated server. Checking for isRemote isn't sufficient because the Minecraft class will not even be loaded so the code statement will not be understandable to the JVM. Instead, you should make a method in your proxy system called something like setViewEntity() and in the common code do nothing but in the client proxy version call your Minecraft code.

 

Okay, now regarding your issue with steering. To debug problems people don't just read code, rather they *trace* (i.e. follow along with) the actual execution to observe what is actually happening. There is no need to guess. I personally do this by simply adding console statements (System.out.println()) throughout my code then watching the console to confirm how things are operating. 

 

For example, in your onInteract() method you should add console statements to confirm that the code path that sets the pilot is executing as expected. And in your control() method you should add statements that firstly confirm the method is being called at all and also confirm that the isRidden code path is the one being followed.

 

And so on. If you do this, you'll quickly find out what is wrong. Either the methods aren't being called at all, or when they are some fields are not the values you expect and so the code doesn't follow the path you expect.

 

So add statements, see if you can notice anything specific going wrong. If you can't figure it out, post the revised code along with the actual console output so we can help.

Why are you comparing the unlocalized names of your Items and not the Items themselves?

It's easier that way for my code.

That's ridiculous, that means you are not storing your Items in variables anywhere(I assume).

Check the GundamItems class.

You've provided no such class.

Then why not

 

player.inventory.getStackInSlot(player.inventory.currentItem).getItem() == GundamItems.item

Or even better

player.getActiveItemStack().getItem() == GundamItems.item

Because I didn't really think I could do that, plus I was writing that code at like 2 AM so I was like subconsciously writing that code. In the next commit, I'll fix that.

Look at the horse class (the abstract one should have the code you want), neither the pig or boat really move - the pig follows the carrot on a stick and the boat appears to literally use the paddles for control (+1 for realism Mojang) which makes it a little useless for your task (if I didn’t read the code wrong and they really are using the paddles). You could also take a look at the minecart class, but there’s lots and lots of track logic.

Good, don't stringly type your code.

I've got some of the movement code from the AbstractHorse class but it's still not moving.

				this.rotationYaw = driver.rotationYaw;
				this.rotationPitch = driver.rotationPitch;
				this.setRotation(this.rotationYaw,this.rotationPitch);
				this.renderYawOffset = this.rotationYaw;
	            this.rotationYawHead = this.renderYawOffset;
	            p_191986_1_ = driver.moveStrafing;
	            p_191986_3_ = driver.moveForward;
	            
	            if(p_191986_3_ <= 0.0F) p_191986_3_ *= 0.25F;

You obviously just cut & pasted that, you need to understand the code. Step through the code with the debugger.

You literally copy & pasted it verbatim it still has SRG arguments & the code still has stuff to do with AI! Make sure that canPassengerSteer can return true. Also please post your entire code not just a snippet

I override canPassengerSteer to make it true.

The SRG Named arguments are there because that's what eclipse said the argument names are.

so what do they do? what is p_191986_1_ and what does it do?

I dunno and eclipse froze when I tried debugging the code in the debugger.

Just now, Spaceboy Ross said:

eclipse froze

That is what is supposed to happen. Did you get prompted to enter debug mode? Did you say yes?

I entered debug mode then eclipse started slowing down everything.

Sorry. Its 2 am here.

Go through the code. Refactor the code i.e.

rename the variables to have names that make sense. Remove stuff that you don't need (if your SURE you don't need it) (HINT: AI stuff)

Please post your entire code.

What do you mean eclipse froze? do you mean Minecraft froze or that Eclipse crashed? Programs are meant to freeze when they hit a breakpoint. Where did you place your breakpoint? did you put it on a variable (breaks on read/write access) or on a line of code (breaks right before the program executes that line)

The 3 variable arguments all are set to 0.0f, so that may be the problem.
