Texture block differently depending on the player's helmet? (ISBRH Help)

[gristly]

Ok, so basically what I want to have is a block that has one texture when the player isn't wearing a certain helmet, and a different one when they do. Right now, I've got the block all set up, as well as a TileEntity that detects whether or not the nearest player is wearing this helmet (which is already fully implemented). The problem is, I can't get the info from the TileEntity every tick in the block to set the texture, and I can't set the texture from the TileEntity. Somebody suggested a TESR or an ISBRH. I haven't delved too much into block rendering, so I really don't know how to implement one or which one I should even use. Any help would be greatly appreciated

Just to make sure, do you want any player to see the second texture if one player is close enough to the block with the helmet ?

If you do, then TESR would be easier.

If you don't, then ISBRH, with Minecraft.thePlayer.getCurrentArmor(... , and the tile entity is unneeded.

[gristly]

OK, sounds like the ISBRH way is best, but I can't figure out how to use it. I don't have a param of Minecraft in any of my methods, and even if I did I can't seem to find the thePlayer field. If someone could write some example code or point me towards a tutorial that would be awesomazing.

 

EDIT: Made a bit of progress, just realised I have to use Minecraft.getMinecraft.etc... thanks! Haven't got it fully working yet, if I do /don't I will post here!

[gristly]

OK, so the code appears to be slightly unreasonable today, so I'll just post my source and hope somebody knows where I went wrong.

 

Block Class

}


}

 

Relevant Part of Main Class

 

ISimpleBlockRenderingHandler OreISBRH = new RenderEnderOre();
		RenderingRegistry.registerBlockHandler(EnderOre.getRenderType(), OreISBRH);

In the load() method.

 

 

ISBRH Class

 

package EnderLore.render;

import cpw.mods.fml.client.registry.RenderingRegistry;

public class RenderEnderOre implements ISimpleBlockRenderingHandler {

@Override
public void renderInventoryBlock(Block block, int metadata, int modelID,
		RenderBlocks renderer) {
	renderer.renderBlockAsItem(block, 0, 1F);


}

@Override
public boolean renderWorldBlock(IBlockAccess world, int x, int y, int z,
		Block block, int modelId, RenderBlocks renderer) {
	// TODO Auto-generated method stub
	renderer.renderStandardBlock(block, x, y, z);
	block.func_111022_d(getOreTexture());

	return false;
}

@Override
public boolean shouldRender3DInInventory() {

	return false;
}

@Override
public int getRenderId() {

	return RenderingRegistry.getNextAvailableRenderId();
}

public String getOreTexture(){

	if(Minecraft.getMinecraft().thePlayer.getCurrentArmor(0).itemID == EnderLore.EnderLore.HelmetOfSeeing.itemID){
		return "EnderLore:EnderOre";
	}
	else
	{
		return "stone";
	}
  
}

}

 

 

Do I need something registered in the Client Proxy? If so, how? or did I just make some really basic mistake? Any help greatly appreciated!

Hi

 

A couple of comments might help

 

1) in renderWorldBlock you need to override the texture before calling renderStandardBlock, not afterwards

2) It might be easier just to override Block.getIcon() and put your texture selection in here

 

(see http://greyminecraftcoder.blogspot.com.au/2013/07/rendering-standard-blocks-cubes.html)

 

Also, Minecraft doesn't update the appearance of the blocks every tick, only when you have made a change (eg placed a block).  So if you put your helmet on or off, you will need to force Minecraft to re-update the scene otherwise you won't see any change.

Cheers  TGG

 

[fhntv24]

the easyest way(like in Thaumcraft with auras) to do that:

 

if (Minecraft.getMinecraft().thePlayer.youCheckIfHelmetIsOn) return OneTexture; else return OtherTexture;

 

p.s. but to make it work it need to be updated,sooo just call setBlock with you id and meta,if you want or make block to be re rendered with

Minecraft.getMinecraft().renderGlobal.markBlockNeedsUpdate(x, y, z);

 

but when update? when player changing helmet,that is when.You can check when player changing helmet with TickHandler(google TickHandler)

[gristly]

OK so now what I have is a block that has the wireframe thing around it, and collides properly, but are completely invisible. I guess the textures aren't working... I guess I'll dump my code again and hope for some help...

public String getOreTexture(){

	if(Minecraft.getMinecraft().thePlayer.getCurrentArmor(0).itemID == EnderLore.EnderLore.HelmetOfSeeing.itemID){
		return "EnderLore:EnderOre";
	}
	else
	{
		return "stone";
	}
  
}

}

 

 

The block and the renderer are both registered in the main class also.

[TheGreyGhost]

Hi

 

Every time you call RenderingRegistry.getNextAvailableRenderID, it returns a new number.

 

Your code should call it once only for your new Block + Renderer, store it, and return this value instead of calling getNextAvailableRenderID every time.

 

-TGG

[gristly]

OK... not sure how I missed that

Anyway, now they render the the missing texture thing if there is a block within a seemingly random area around them that isn't one of them, otherwise they are invisible... weird. I will take another look at my code I guess.

[gristly]

OK, so now the custom blocks always render as stone, and any blocks within a certain area of them (it seems to be different for every one) is also rendered as stone. weird, eh? I guess I'll dump my code again
