How do I animate textures?

[ocomobock]

 

 

 

I'm trying to create a new compass that points at a random player on the server when you right click with it.

 

My current problem is that it doesn't recognize my file because it's 16x512. This is the error I get when it tries to load the texture:

 

[WARNING] [Minecraft-Client] TextureManager.createTexture: Skipping mods/combatbars/textures/items/playercompass.png because of broken aspect ratio and not animation

 

I can't figure out how the original compass can use a 16x512 png without getting any errors. Does anyone know how to do this?

 

Here's all my code:

 

Outside of the load method

public static Item playercompass;

 

In the load method

playercompass = (new ItemPlayerCompass(3841)).setUnlocalizedName("combatbars:playercompass").setCreativeTab(CreativeTabs.tabTools);

LanguageRegistry.addName(playercompass, "Player Compass");

ItemPlayerCompass

 

 

package ocomobock.healingbar;

import java.util.Random;

import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.util.ChunkCoordinates;
import net.minecraft.util.MathHelper;
import net.minecraft.world.ChunkCoordIntPair;
import net.minecraft.world.World;

public class ItemPlayerCompass extends Item{

public ItemPlayerCompass(int par1) {super(par1);}

public ItemStack onItemRightClick(ItemStack stack, World par2World, EntityPlayer p)
{
    	ChunkCoordinates chunkcoordinates = par2World.getSpawnPoint();
    	p.addChatMessage(Integer.toString(par2World.playerEntities.size()) + TexturePlayerCompass.playerPointingAt);
    	EntityPlayer pp = TexturePlayerCompass.entityplayer;
	TexturePlayerCompass.r = new Random();
	p.addChatMessage(chunkcoordinates.posX + "," + chunkcoordinates.posZ + " --- " + TexturePlayerCompass.isOnePlayer);
	return stack;
}
}

 

 

The original compass is just a normal item with no special class. Mine obviously has one just because of the onItemRightClick method.

 

Anyway, if anyone could help that would be awesome.

 

EDIT: I was testing stuff in ItemPlayerCompass, but that class isn't really important right now.

Have you tried re-skinning the normal in-game compass before? I wonder if compass.txt needs editing....

[endershadow]

make sure the height is a multiple of the width

[SanAndreaP]

I had this problem, too. Just make a txt file next to your animated texture, name it the same as the texture and you should be fine. Leave the txt file blank.

For example:

texture.png  <==>  texture.txt

[ocomobock]

Thank you, that seemed to have worked.

 

EDIT: The compass is spinning randomly now. But, nobody else probably has any experience with this so I'll just try to figure it out on my own.

 

My guess is that it somehow isn't finding the proper way to animate the texture and reverts to the default animation, which just goes through each panel every few ticks. But I have no idea why <_<

[ocomobock]

Does anyone wanna help with this? I wasn't able to figure it out and I have no idea what I could be doing wrong.

 

If someone wants to really try and help (unlikely) you could get TeamViewer and remotely edit my code. That would be a lot more efficient than through replies and stuff.

 

You don't have to get TeamViewer, but it would probably be a lot easier that way

In your Item class, where do you register your texture?

[ocomobock]

I didn't think I needed to do that because I added this in the main class:

 

playercompass = (new Item(3841)).setUnlocalizedName("playercompass:playercompass").setCreativeTab(CreativeTabs.tabTools);

 

I guess I forgot to add that. Also, sorry I took 3 days to reply, I forgot about this thread somehow.

What you should have is following:

- Have an own Item class (here ItemMyCompass)

- Have an own TextureStitched class (here TextureMyCompass, you can copy the code from the TextureCompass class and change the stuff in that code, it's what I did)

Seems like you have both. In order to "bind" the TextureStitched to your item, do these lines of code in your updateIcons method (if you don't have one, create and override one):

Minecraft.getMinecraft().renderEngine.textureMapItems.setTextureEntry("playercompass:playercompass", new TextureMyCompass());
this.iconIndex = TextureMyCompass.compassTexture;

The first line registers the TextureStitched to Minecraft and binds the right texture for it. "playercompass:playercompass" is the string you would also normally use when you register an "ordinary" texture

The second line grabs the newly created instance from the custom TextureStitched class and assigns it to the texture field of the Item.

 

[ocomobock]

Minecraft.getMinecraft().renderEngine.textureMapItems.setTextureEntry("playercompass:playercompass", new TextureStitchedPlayer());

 

This line gives me two errors. setTextureEntry basically says the arguments don't match (String, TextureStitched) and (String, TextureStitchedPlayer). 'new TextureStitchedPlayer()' wants me to add a String as an argument.

 

Maybe I could add "playercompass:playercompass" to the second error, and for the first one I'm not really sure. I can't just use TextureStitched. Maybe I could make a new TextureMap class (where setTextureEntry is from).

 

I'll try to do both of those and see if they work.

 

EDIT: Okay, making a new TextureMap class didn't work at all. But I made TextureStitchedPlayer extend TextureStitched and that fixed the first error. And I fixed (maybe) the second error by putting "playercompass:playercompass".

 

EDIT 2: Nothing I'm trying is working at all and now I have "missing texture" as the texture.

Maybe it has changed in a newer Version of Forge. I have to look into this...

[ocomobock]

I really wish I could figure these things out. I can only make simple things like new mobs and items and stuff, I wish I could make something unique for once

 

But yeah, I pretty much give up on this unless anyone else wants to help.
