[[Solved] Different variable values for each player]

This sounds a lot like a Java question, and it also sounds like you might be using the static keyword. Post some code, I'll take a look.

[[1.7.10]Player lookup from UUID returns null]

Has anyone got any idea why this might be happening?

 

Should I try switching the Entity to inherit from EntityTameable, and use the vanilla EntityAIFollowOwner?

If I did, how would I set the owner the moment the egg hatched, rather than when it was fed a certain item?

[[1.7.10]Player lookup from UUID returns null]

Oh, right! Now I get it. Thanks for clearing that up.

 

I pretty much copied the way EntityAIFollowOwner does it, except I don't use data watchers because I am not familiar with them.

 

A UUID is used in the Entity, because it is passed in from the egg it hatches from.

 

An EntityPlayer is used in the AI, because otherwise I'd be calling worldObj.func_152378_a(UUID) all the time to get one for the information required to move towards it.

[[1.7.10]Player lookup from UUID returns null]

Forgive my ignorance, but I'm not sure what you mean. Is it in two places?

[[1.7.10]Player lookup from UUID returns null]

In the Entity's readFromNBT(NBTTagCompound), line 196.

 

m_FollowAI.SetOwner(m_OwnerID, m_OwnerDimension);

[[1.7.10]Player lookup from UUID returns null]

Here's the Entity:

And here's the following AI, where the owner is being set:

[[1.7.10]Player lookup from UUID returns null]

I'm not sure I can, since the loading occurs in the entity class. Is there a way for me to check when the player logs in, inside of that class?

 

Just did the dimension saving thing; it made no difference, still returns null.

[[1.7.10]Player lookup from UUID returns null]

How do I go about doing those things?

[[1.7.10]Player lookup from UUID returns null]

World.func_152378_a(UUID) is supposed to return an EntityPlayer, but when I try to call it with a saved player ID (at world load, using NBT tags), it returns null. Does anyone know what I'm doing wrong?

[[1.8][SOLVED] Attribute Modifier Help]

You shouldn't be storing the player, store their UUID, like so:

 

protected UUID m_ownerID;

 

Save it to NBT by writing it to a string, then load it from string and use UUID.fromString(string) to get it back.

[[1.7.10][SOLVED]Changing model at runtime]

I'll elaborate:

I realise there's one renderer for all entities, yes.

What I'm doing is saving the age within the entity, then when the entity changes life stages, it sets a static ModelBase in the renderer to the new model, then changes the model field at the start of every render call. Feels pretty hacky, but it gets the job done.

 

...I also get the feeling this shouldn't work. But it does, so yay!

[[1.7.10][SOLVED]Changing model at runtime]

[move]TRIPLE COMBO POST[/move]

 

So I solved it. I just set the super's mainModel to the static model I have in my renderer, which can be changed by calling a function. It seems to work just fine.

[[1.7.10][SOLVED]Changing model at runtime]

Are there any good, 1.7.10 tutorials on custom mob rendering? I'm utterly useless when it comes to graphics programming, so I could use all the help I can get.

 

_{Sorry for the double post.}

[[1.7.10][SOLVED]Changing model at runtime]

My super class is RenderLiving.

[[1.7.10][SOLVED]Changing model at runtime]

My graphics programming skills are awful, so I call super.doRender and leave it at that. That's going to stop me changing my model, isn't it?

[[1.7.10][SOLVED]Changing model at runtime]

Sorry to bring up a slightly old topic, have been ill a few days.

 

So I've got texture swapping working, but not model swapping.

 

You are passing entity arguments into render method - save some field inside entity (age) and use it insdie render method to e.g scale model down, or even use different model.

 

How would I go about that? RenderEntityLiving's mainModel is a protected non-static value, and as far as I know, that's what's used for rendering. (Or renderPassModel, one of the two)

[[1.7.10][SOLVED]Changing model at runtime]

Is it possible to change an entity's model at runtime?

 

I'm having some trouble with my tamagotchi mod, wherein my 'gotchi has to age up and change model. Now, I have two options; change the model at runtime, or instantiate a new class and delete the old instance.

 

So if it's not possible to change an entity's model at runtime, how would I go about deleting the old instance?

[[1.7.10][SOLVED]What's the best way to find out if an Item is food?]

My Java's a bit rusty, so that really helped me out. That did it! Thanks, Ernio.

[[1.7.10][SOLVED]What's the best way to find out if an Item is food?]

So I want to feed my creature stuff, and I've overridden the interact() function. But I need to find out if the player is currently holding food.

 

How would I go about doing that?

 

I thought about using Object#isAssignableFrom(Class<?>) but I don't think that will work. I hope this isn't too much of a Java question.

[[1.7.10][SOLVED]Is it possible to get the player who placed a block?]

Turns out it is possible, but it uses World.func_152378_a(UUID).

[[1.7.10][SOLVED]Is it possible to get the player who placed a block?]

Above, and note: you can get player.getUUID() to save player to TileEntity's NBT (one UUID = one player).

To retrieve: MinecraftServer#getEntityFromUuid(UUID uuid) // I think there is player-specific method, yet I don't remember

 

Note: UUIDs are only working on server side.

 

EDIT

Yup, there is: World#getPlayerEntityByUUID(UUID uuid) - but it works per-world.

 

I can only find World#getPlayerEntityByName(). Is it perhaps a 1.8 feature, or am I missing something?

[[1.7.10][SOLVED]Is it possible to get the player who placed a block?]

Thanks for all the help! I should be able to figure it out now, but if not, I'll report back.

[[1.7.10][SOLVED]Is it possible to get the player who placed a block?]

For my tamagotchi mod, I need to assign a player as an owner of a 'gotchi. I've got a tile entity representing the egg, which hatches into an entity, at which point it should start following a player around.

 

So, is it possible to get the player who placed the egg down? If not, what might be a good way of assigning an owner to a new 'gotchi?

[[1.7.10][SOLVED]Shapeless recipe not registering]

No, but I figured it out.

 

I was registering the recipe before I was registering the poop block, so it was getting nothing.

 

I feel so stupid.

[[1.7.10][SOLVED]Shapeless recipe not registering]

More questions!

 

So I've got a shapeless recipe, of one dirt block and one poop, but it just doesn't work. What am I doing wrong? I apologise in advance if it's something glaringly obvious.

 

 

GameRegistry.addShapelessRecipe(new ItemStack(gotchiFertiliser, 4), new ItemStack(Blocks.dirt), new ItemStack(BlockRegistry.poopBlock));

 

 

EDIT: Just to add, the code is most certainly being executed. I have a print statement above it that triggers.
