I have a block with a custom amount of "power" in it, and I want the block to get brighter as there is more power.  I have three textures I want to use for different power ranges, but when the block gets into a new power range, it dosen't update.  If I place a block next to it, or force it to update, it works, but it won't work on it's own.  I think it might have something to do with textures being client-side and tile entities being server-side, but I dont know how to fix it.  Thanks in advance for any help.

Hi

 

Block textures only update when there is a change.  When rendering Blocks, minecraft uses a 'cached renderlist'  that is only refreshed when the block changes.  So if you try to animate your Block using the Block rendering methods above, you won't see anything until the Block is changed or updated.

If you want your Block to be animated without updating it, you need to either use an animated texture for your Block, or use a TileEntity with TileEntitySpecialRender.

 

For more info see here

Actually all you have to do is update the block when you want the texture to change using

worldObj.markBlockForUpdate(xCoord, yCoord, zCoord);

Just make sure you are also synchronising the client tile data with the server using

@Override
public Packet getDescriptionPacket() {
NBTTagCompound tagCompound = new NBTTagCompound();
this.writeToNBT(tagCompound);
return new S35PacketUpdateTileEntity(this.xCoord, this.yCoord, this.zCoord, 1, tagCompound);
}

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

I have the renderer, but the texture flickers, and sometimes disapears.

 

Here's my code:

Renderer:

 

 

package Technomage3.both.Renderers;

import net.minecraft.client.renderer.Tessellator;
import net.minecraft.client.renderer.texture.TextureMap;
import net.minecraft.client.renderer.tileentity.TileEntitySpecialRenderer;
import net.minecraft.tileentity.TileEntity;
import net.minecraft.util.ResourceLocation;

import org.lwjgl.opengl.GL11;

import Technomage3.both.Blocks.tileentities.TileEntityMagicRune;
import Technomage3.both.Models.ModelMagicRune;

public class MagicRuneRenderer extends TileEntitySpecialRenderer {

@Override
public void renderTileEntityAt(TileEntity tileentity, double d0, double d1,
		double d2, float f) {
	renderRune((TileEntityMagicRune) tileentity, d0, d1, d2, f);

}

private void renderRune(TileEntityMagicRune tile, double x,
		double y, double z, float f) {

	Tessellator tessellator = Tessellator.instance;
    
	this.bindTexture(getTexture(tile.getPowerLevel()));
    GL11.glPushMatrix();
    GL11.glTranslated(x, y, z);
    tessellator.startDrawingQuads();
    
    tessellator.addVertexWithUV(0, 0, 0, 0, 0);
    tessellator.addVertexWithUV(0, 0, 1, 0, 1);
    tessellator.addVertexWithUV(1, 0, 1, 1, 1);
    tessellator.addVertexWithUV(1, 0, 0, 1, 0);

    tessellator.addVertexWithUV(0, 0, 0, 0, 0);
    tessellator.addVertexWithUV(1, 0, 0, 1, 0);
    tessellator.addVertexWithUV(1, 0, 1, 1, 1);
    tessellator.addVertexWithUV(0, 0, 1, 0, 1);
    
    tessellator.draw();
    GL11.glPopMatrix();

}

private ResourceLocation getTexture(int power) {

	if(power > 30){

		return icons[2];

	} else if(power > 0){

		return icons[1];

	} else{

		return icons[0];

	}

}

private ResourceLocation[] icons = new ResourceLocation[]{

		new ResourceLocation("tn3", "textures/blocks/magicRuneLow.png"),
		new ResourceLocation("tn3", "textures/blocks/magicRuneMid.png"),

You probably have z-fighting. That's when two textures are fighting to get rendered. You see stripes of both textures and they change if you move. You can fix that by changing the z-level.

Don't PM me with questions. They will be ignored! Make a thread on the appropriate board for support.

1.7.10 and older versions of Minecraft are no longer supported due to it's age! Update to the latest version for support.

The redstone block just has a small hitbox, and the part of the texture you see is the transparant part of the texture.
