Is it possible for an entity to emit a red stone signal?

[tlr38usd]

Could I make an entity that either powers the block it's on or the block underneath it with a red stone signal? I know that computercraft turtles can emit redstone signals and I'm pretty sure they are entities.

Computer craft turtles are entities only when moving.  When still they are a block + tile entity, which can emit signals.

Alright. Well currently the way I'm doing it is adding a transparent non-solid block to the world wherever I want the entity to emit a red stone signal. However it still has the black line around it when I hover my mouse over it and it still acts like a block. Is there a way to make it behave like air so players don't have to break it before placing another block and don't have to see the black border?

 

Also what would be the onupdate for blocks? I'd like it to disappear it to air after x amount of ticks.

 

edit: I got the border to disappear with.

public MovingObjectPosition collisionRayTrace(World par1World, int par2, int par3, int par4, Vec3 par5Vec3, Vec3 par6Vec3)
    {
        float f = 0.15F;

        this.setBlockBounds(0.0F, 0.0F, 0.0F, 0.0F, 0.0F, 0.0F);

        return super.collisionRayTrace(par1World, par2, par3, par4, par5Vec3, par6Vec3);
    }

However I'm not sure this is the best way to do it because now there is no way to break it...

Black line:

public AxisAlignedBB getCollisionBoundingBoxFromPool(World par1World, int par2, int par3, int par4)
    {
	return null;
    }

 

Block (re)placement:

public boolean isBlockReplaceable(World world, int x, int y, int z)
    {
        return true;
    }

 

On update (you could have found this one yourself by searching Block.java):

public void updateTick(World par1World, int par2, int par3, int par4, Random par5Random) {}

I already had the first and the last one, thanks for the isBlockReplaceable though! =D

 

My problem with updateTick though is that it does not update as much as I'd like it, is there a way to speed it up? I have tried tick handlers but I'm not sure how to get the block's coordinates.

Don't use random ticks

 

onBlockAdded(...) {
    world.scheduleBlockUpdate(x,y,z,how_many_ticks);
}

Like this?

public void onBlockAdded(World par1World, int par2, int par3, int par4)
    {
	par1World.scheduleBlockUpdate(par2, par3, par4, 5, 5);
    }

 

There was an extra parameter I needed to add and I wasn't sure what it did. I set it really small so I could see it happening but it doesn't disappear.

The extra param is the one after par4, its the block ID of the block making the update call (you can set it to this.blockID).

 

You still need an updateTick(...) function to deal with it.

Thanks that works!
