Hey guys,

 

I have two different questions regarding the use of Redstone.

 

 

1.

I'm making a set of blocks which work just like redstone wire, but it's a physical block that can be placed anywhere. It's all worked except one thing; the redstone wont transmit vertically. Anyone know how I might achieve that? Here's the block's class file:

 

package co.uk.silvania.roads.block;

import java.util.List;
import java.util.Random;

import co.uk.silvania.roads.Roads;
import net.minecraft.block.Block;
import net.minecraft.block.BlockRedstoneWire;
import net.minecraft.block.material.Material;
import net.minecraft.client.renderer.texture.IconRegister;
import net.minecraft.entity.Entity;
import net.minecraft.item.Item;
import net.minecraft.util.AxisAlignedBB;
import net.minecraft.util.Direction;
import net.minecraft.world.IBlockAccess;
import net.minecraft.world.World;

public class PowerPoleBlock extends BlockRedstoneWire {

private Material material;

public PowerPoleBlock(int id) {
	super(id);
	this.setCreativeTab(Roads.tabRoads);
        //this.setBlockBounds(0.4F, 0.0F, 0.4F, 0.6F, 1.0F, 0.6F);
}

    public void registerIcons(IconRegister iconRegister) {
        blockIcon = iconRegister.registerIcon("Roads:CementBlock");
    }
    
    @Override
    public int getRenderType()
    {
        return 0;
    }
    
    public AxisAlignedBB getCollisionBoundingBoxFromPool(World par1World, int par2, int par3, int par4)
    {
        return AxisAlignedBB.getAABBPool().getAABB((double)par2 + this.minX, (double)par3 + this.minY, (double)par4 + this.minZ, (double)par2 + this.maxX, (double)par3 + this.maxY, (double)par4 + this.maxZ);
    }
    
    @Override
    public void addCollisionBoxesToList(World par1World, int par2, int par3, int par4, AxisAlignedBB par5AxisAlignedBB, List par6List, Entity par7Entity) {
    	this.setBlockBounds(0.4F, 0.0F, 0.4F, 0.6F, 1.0F, 0.6F);
    	super.addCollisionBoxesToList(par1World, par2, par3, par4, par5AxisAlignedBB, par6List, par7Entity);
    }
    @Override
    public boolean canPlaceBlockAt(World par1World, int par2, int par3, int par4)
    {
	return true;
    }
    
    @Override
    public int idDropped(int par1, Random par2Random, int par3)
    {
        return Roads.powerPole.blockID;
    }
    
    public static boolean isPowerProviderOrWire(IBlockAccess par0IBlockAccess, int par1, int par2, int par3, int par4)
    {
        int i1 = par0IBlockAccess.getBlockId(par1, par2, par3);

        if (i1 == Roads.powerPole.blockID)
        {
            return true;
        }
        else if (i1 == 0)
        {
            return false;
        }
        else
        {
            int j1 = par0IBlockAccess.getBlockMetadata(par1, par2, par3);
            return par4 == (j1 & 3) || par4 == Direction.rotateOpposite[j1 & 3];
        }
    }

    
    @Override
    public void randomDisplayTick(World par1World, int par2, int par3, int par4, Random par5Random)
    {
    	//Remove here to end of constructor - Only kept in for testing to see when the current is active.
        int l = par1World.getBlockMetadata(par2, par3, par4);

        if (l > 0)
        {
            double d0 = (double)par2 + 0.5D + ((double)par5Random.nextFloat() - 0.5D) * 0.2D;
            double d1 = (double)((float)par3 + 0.0625F);
            double d2 = (double)par4 + 0.5D + ((double)par5Random.nextFloat() - 0.5D) * 0.2D;
            float f = (float)l / 15.0F;
            float f1 = f * 0.6F + 0.4F;

            if (l == 0)
            {
                f1 = 0.0F;
            }

            float f2 = f * f * 0.7F - 0.5F;
            float f3 = f * f * 0.6F - 0.7F;

            if (f2 < 0.0F)
            {
                f2 = 0.0F;
            }

            if (f3 < 0.0F)
            {
                f3 = 0.0F;
            }

            par1World.spawnParticle("reddust", d0, d1, d2, (double)f1, (double)f2, (double)f3);
        }
    }
    
    public int idPicked(World par1World, int par2, int par3, int par4)
    {
        return Roads.powerPole.blockID;
    }

}

 

 

2.

Is it possible to change the texture of a tile entity, using redstone? Here's my Renderer class, the if function takes no effect right now so what do I need to change?

 

package co.uk.silvania.roads.tileentities;

import org.lwjgl.opengl.GL11;


import co.uk.silvania.roads.Roads;
import co.uk.silvania.roads.client.TrafficLightModel;

import net.minecraft.client.renderer.Tessellator;
import net.minecraft.client.renderer.tileentity.TileEntitySpecialRenderer;
import net.minecraft.entity.Entity;
import net.minecraft.tileentity.TileEntity;
import net.minecraft.world.IBlockAccess;
import net.minecraft.world.World;


public class TileEntityTrafficLightRenderer extends TileEntitySpecialRenderer {

private final TrafficLightModel model;

    private final boolean powered;

public TileEntityTrafficLightRenderer(boolean par2) {
	this.model = new TrafficLightModel();
    this.powered = par2;
}

@Override
public void renderTileEntityAt(TileEntity te, double x, double y, double z, float scale) {
	GL11.glPushMatrix();
	GL11.glTranslatef((float) x + 0.5F, (float) y + 1.5F, (float) z + 0.5F);
	if (this.powered) {
		bindTextureByName("/mods/roads/textures/blocks/TrafficLightPoleGreen.png");
	} else {
		bindTextureByName("/mods/roads/textures/blocks/TrafficLightPoleRed.png");			
	}
	GL11.glPushMatrix();
	GL11.glRotatef(180F, 0.0F, 0.0F, 1.0F);
	this.model.render((Entity)null, 0.0F, 0.0F, -0.1F, 0.0F, 0.0F, 0.0625F);
	GL11.glPopMatrix();
	GL11.glPopMatrix();
}

private void adjustRotatePivotViaMeta(World world, int x, int y, int z) {
	int meta = world.getBlockMetadata(x, y, z);
	GL11.glPushMatrix();
	GL11.glRotatef(180F, 0.0F, 0.0F, 1.0F);
	GL11.glPopMatrix();
}

private void adjustLightFixture(World world, int i, int j, int k, Block block) {
	Tessellator tess = Tessellator.instance;
	float brightness = block.getBlockBrightness(world, i, j, k);
	int skyLight = world.getLightBrightnessForSkyBlocks(i, j, k, 0);
	int modulousModifier = skyLight % 65536;
	int divModifier = skyLight / 65536;
	tess.setColorOpaque_F(brightness, brightness, brightness);
	OpenGlHelper.setLightmapTextureCoords(OpenGlHelper.lightmapTexUnit,  (float) modulousModifier,  divModifier);
}
}

1) I did it once.  It was a bitch.  I'll dig up my code.  I will note, however, that it only went up not down.  I do have another block that could take input signals from redstone and "do stuff" by propagating the signal, but it didn't turn off instantly (also redstone didn't see it as transmitting power).

 

2) Yes.  Just set up the block to have an isPowered function determine if it is powered, then send that flag into the TE.  I did something similar with my spikes, only it was based on having hurt an entity.

 

Edit:

Redstone fence (upward redstone signal transmission)

Note: this block was intended to ONLY take a signal from a solid block or itself from below itself.  It was not meant for any kind of horizontal transmission.

Redstone phaseblock (propagation of signal in all directions)

Note: it does not have an instant-off and I was unable to figure out why and just left it alone because it was good-enough for my needs.

Base class isn't really relevant here, it was just the core of how the blocks became non-solid by whatever means that they became non-solid by (e.g. something would tweak the metadata value and that would cause it to change texture and lose collision checks).

thanks :D I think I can combine your code with what I already have to make my block emit in all six directions. If I get it working, do you want the code?

 

Also, a third redstone question. Is it possible to make a block say "If the block beneath me has power, I will do something"?

 

With my traffic lights, I want them to be redstone controlled for their state. But, I don't want the redstone on show, so it'd make sense to check if the block below it is powered.

 

 

EDIT: Also, any chance I can see your "BaseRedstone" class? You have a few references to it, I wanna see what I need to change those to

For checking if a block below is powered use this example:

 

if(world.isBlockProvidingPowerTo(x, y - 1, z, direction))

{

this.doSomething();

}

 

y - 1 to check block below your block

direction would be up(above) for checking if it powers your block (I think up is 1 or 0)

Nah, I'm perfectly happy with what I have and apparently everyone else is too.

On neighbor changed, check the block below for isSupplyingStrongPower (or isSupplyingWeakPower).

Oh, that's just a config option for how far the signal can travel vertically.  Minimum is 1 (signal travels 16 blocks) default is 3 (signal travels 5 blocks).  Just because I felt like the signal shouldn't be as efficient, but left it modifiable by the user.
