Hello, I want to create a block like the target block in the Minecraft 1.7.10 version. I am a beginner in Forge Modding, so I am struggling a lot with it.

The block should detect arrows that hit him and then tell me where they hit him, so I can calculate a number that should present by a redstone signal how close the block to the center is.

But my problem is that I do not know how the block can tell me where the arrow is.

I tried to copy some code of the target of the OpenBlocks Mod, but they have created classes like TileEntityTarget, that extends SyncedTileEntity that extends OpenTileEntity that extends TileEntity so I ended up with trying to edit the code and failing a lot...

Here is my code:

@Override
public void onEntityCollidedWithBlock(World world, int x, int y, int z, Entity entity) {

if (!world.isRemote && entity != null && entity instanceof EntityArrow) {
if (lastEntityHit != entity.getEntityId()) {
lastEntityHit = entity.getEntityId();
return;
}
lastEntityHit = entity.getEntityId();
onTargetHit(world, x, y, z, Vec3.createVectorHelper(entity.posX, entity.posY, entity.posZ));
}
}

public void onTargetHit(World world, int x, int y, int z, Vec3 entityPosition) {

if (world.isRemote) return;

final TileEntity target = getTileEntity(world, x, y, z, TileEntity.class);
if (target == null) return;

Vec3 bullseye = Vec3.createVectorHelper(x, y, z);

double distance = entityPosition.distanceTo(bullseye);

BlockTargetBlock.setStrength(15 - Math.min(15, Math.max(0, (int)(distance * 32))));

}

@Override
public int isProvidingWeakPower(IBlockAccess world, int x, int y, int z, int m) {
final TileEntity tile = getTileEntity(world, x, y, z, TileEntity.class);
return tile != null? BlockTargetBlock.getStrength() : 0;
}

@Override
public int isProvidingStrongPower(IBlockAccess world, int x, int y, int z, int m) {
return isProvidingWeakPower(world, x, y, z, m);
}

@Override
public AxisAlignedBB getSelectedBoundingBoxFromPool(World world, int x, int y, int z) {
setBlockBoundsBasedOnState(world, x, y, z);
return super.getSelectedBoundingBoxFromPool(world, x, y, z);
}

@Override
public AxisAlignedBB getCollisionBoundingBoxFromPool(World world, int x, int y, int z) {
setBlockBoundsBasedOnState(world, x, y, z);
return super.getCollisionBoundingBoxFromPool(world, x, y, z);
}

private TileEntity getTileEntity(IBlockAccess world, int x, int y, int z, Class<TileEntity> class1) {
return (worldObj != null && worldObj.blockExists(x, y, z))? worldObj.getTileEntity(x, y, z) : null;
}

public static void setStrength(int strength) {
BlockTargetBlock.strength = strength;
tickCounter = 10;
worldObj.notifyBlocksOfNeighborChange(xCoord, yCoord, zCoord, null);
}

public static int getStrength() {
return strength;
}

I would be glad if someone could help me out. They don't have to give me the code, it would be enough if I could get a tip or a link to an article or video or something like this that could explain me how I can do it or at least give me also useful tips.

Greetings,

Hey,

I am playing my modpack in 1.7.10 and I recently crafted a power fist. I installed the pickaxe, axe and shovel modules as well as a battery that is completely charged. I overclocked the modules to harvest speed x30, but there wasn't any effect. It was as fast as a normal stone tool. All the other modules seemed to work fine.

I didn't set any keybinds, so that can't be the problem and I am in gamemode 0.

I play on a server, but I also tested it in singleplayer and it didn't work.

I installed the newest version.

I would very appreciate it if somebody could help me.

PS: I tried out different kinds of stone and wood, like cobblestone, clean stone and oak wood, but there was no difference.
