So I'm trying to make an electric cable system, which obviously requires an ability to connect/detach from other cables. Currently I am only working on the aesthetics and so want to change whether or not each part of a wire is shown.

My wire model is made in Techne and consists of 7 parts (a core and up, down, north, south, east, west). They can be toggled currently when the model is first instanced using a boolean for each direction (I don't need to toggle the core):

public RenderCable()
{
this.modelCable = new ModelCableAll(true, true, true, false, false, false);
}

 

The problem with this is that the state can only be changed by restarting the game, so how can I live update the state/edit the existing instance/remake the instance of the model?

 

Here is the full class:

package foodTech.tileEntities.render;

import net.minecraft.client.Minecraft;
import net.minecraft.client.renderer.tileentity.TileEntitySpecialRenderer;
import net.minecraft.entity.Entity;
import net.minecraft.tileentity.TileEntity;
import net.minecraft.util.ResourceLocation;

import org.lwjgl.opengl.GL11;

import foodTech.tileEntities.models.cable.ModelCableAll;

public class RenderCable extends TileEntitySpecialRenderer {

    ResourceLocation textureOff = (new ResourceLocation("roboguy99:textures/models/cableOff.png"));
    ResourceLocation textureOn = (new ResourceLocation("roboguy99:textures/models/cableOn.png"));

private final ModelCableAll modelCable;

public RenderCable()
{
	this.modelCable = new ModelCableAll(false, false, false, false, false, false);
}

public void renderTileEntityAt(TileEntity tileEntity, double x, double y, double z, float scale) 
{
	GL11.glTranslatef((float) x + 0.5F, (float) y - 0.5F, (float) z + 0.5F);
	setConnections();
	GL11.glTranslatef((float) x - 0.5F, (float) y + 0.5F, (float) z - 0.5F);
}

public void setConnections()
{
	GL11.glPushMatrix();
		Minecraft.getMinecraft().renderEngine.bindTexture(textureOff);
		this.modelCable.render((Entity)null, 0.0F, 0.0F, -0.1F, 0.0F, 0.0F, 0.0625F);
	GL11.glPopMatrix();
}
}

Add the following to your tileentity class

 

@Override
public void onDataPacket(NetworkManager net, S35PacketUpdateTileEntity pkt) {
NBTTagCompound nbttagcompound = pkt.func_148857_g();
this.readFromNBT(nbttagcompound);
}

@Override
public Packet getDescriptionPacket() {
NBTTagCompound nbttagcompound = new NBTTagCompound();
this.writeToNBT(nbttagcompound);
return new S35PacketUpdateTileEntity(this.xCoord, this.yCoord, this.zCoord, this.blockMetadata, nbttagcompound);
}

 

this will sync to the client, mostly used for renders.

Thanks. I'll test this out tomorrow and get back to you, as it's late now.
