[1.7.10] Issues with Pipe connections (mechanical)

Minothor · August 22, 2014

I'm currently working on a power system for a friend's mod, however I'm hitting a bit of a snag.

So far the cables only seem to be connecting successfully in the vertical (y) direction and transferring MF power packets accordingly.

Visually, connections will only show up once the chunk has been reloaded so I'm guessing I'm failing with the update packet somewhere.

Does anyone have any idea what I'm doing wrong here?

The Actual TileEntity and source of the stress here, it's meant to keep an array of connected sides and update it when neighbours change.

package net.RPower.RPowermod.machines.power;

import RPower.api.power.I_MFSink;
import RPower.api.power.I_MFSource;
import RPower.api.power.cable.I_MFCable;
import net.RPower.RPowermod.machines.power.cable.TileEntityFluxCable;
import net.minecraft.tileentity.TileEntity;

public class MFHelper {


public static boolean checkConnectable(TileEntity tileEntity) {
	boolean result = (tileEntity instanceof I_MFSink || tileEntity instanceof I_MFSource);
	if (result)
		System.out.println("Success!");
	System.out.println(tileEntity.toString());
	return result;
}

}

Anything I need to handle frequently will be offloaded into this class for neatness.

Currently it only checks if a tileEntity implements either of the interfaces for MFcables to connect to. (I_MFCable extends both I_MFSink and I_MFSource)

Cheers in advance and sorry about the code flood, the full source is on this branch:

Sorry to bump this, but I'm still struggling to make this work.

Currently it's connecting and transferrign packets perfectly in the -y direction, but none other. I've tried altering the direction code to no avail and the visual connection updates still only load after a chunk reload. I've tried both notifyBlockUpdate(x,y,z,block) and scheduleBlockUpdate(x,y,z,block,metaD), both to no avail.

If anyone has any insights into this, I'd be extrememy grateful!

Could you show me how you render your pipes? Do you have a tile entity special renderer binded somewhere?

Are the print in your check connections printing the right values? If they are not try considering make it look fancier using ForgeDirection(s can't remember if plural). Write and read nbt should be good, but check them too (they are used to sync with the client after all and you never know). While you are at it, put some print in that renderer and see if it receive the right stuff. If it does, you know where the problem lies then

As for binding, yes it's registered in the clientProxy in the function:

@Override
public void registerRenderers(){
	ClientRegistry.bindTileEntitySpecialRenderer(TileEntityFluxCable.class, new TileEntityFluxCableRenderer());
}

From the console output, it finds the cables on the right sides and returns "true", if I set the connections array manually, either in the code or with the onBlockActivated, I get get it to correctly display or connect to any dirction I wish without issue, it really is just the automatic connection mode.

I hadn't heard of ForgeDirections though, I'll take a look at that, thanks! I was using the side-to-direction mapping that Grey's site gives, calculating the details from the (0 to 5)%2 for positive/negative switching and (0 to 5)/2 for the three axis.

LordMastodonFTW · August 25, 2014

In my opinion I think you would be better off hardcoding it in GL, because this way you don't have to create a new model in Techne for every option. You can simply use GL.rotatef(params here) and only have to create the basic pipe and the pipe connection. Also, ForgeDirection is an Enum which pairs a number to every compass point you can be looking at and UP and DOWN. So, for instance, 0 is South, and 1 is North, and things like that. You can use these to determine on which compass point/UP or DOWN the pipe is at and create a visual connection. As to your mechanical problem, I'm not entirely sure of the solution, as I have never really done something like it, but I'm sure someone else will present the solution.

Whov · August 25, 2014

Yea, I would really recommend using OpenGL (here's a tut by a great teacher:

). Moreover, if I recall correctly, Forge directions has arrays for every direction like {+1;0;0} for north or something, so you don't have to use that huge (compared to how long it could become) code to get the direction you want. Besides, it looks to me like your problem is indeed in check connections, so we'll need to improve it. I might write something for you later today (for reference: 12 am now)

Minothor · August 25, 2014

I think I'll have to swap over to the directions Enum actually, it sounds much neater and somewhat less frustrating.

as for the openGL, I've been sorely tempted to, this started out as a proof of cencept, to let me see the connections that the pipes were making on the code level.

also, another little update, by adding the following to the Block class, I'm getting some rather interesting results..

@Override
public void onNeighborChange(IBlockAccess world, int x, int y, int z,int tileX, int tileY, int tileZ) {
	if(world.getBlock(tileX, tileY, tileZ).hasTileEntity(0) &&MFHelper.checkConnectable(world.getTileEntity(tileX, tileY, tileZ)))
	{
		int diffX=x-tileX;
		int diffY=y-tileY;
		int diffZ=z-tileZ;

		int side = 0;

		if (diffX!=0)
			side=4;
		if (diffZ!=0)
			side=2;
		if (diffY!=0)
			side=0;

		int sideDir=(diffX<0||diffY<0|diffZ<0)?0:1;

		side+=sideDir;

		((TileEntityFluxCable)world.getTileEntity(x, y, z)).connections[side]=true;
		((TileEntityFluxCable)world.getTileEntity(tileX, tileY, tileZ)).connections[side-=sideDir]=true;
	}
	super.onNeighborChange(world, x, y, z, tileX, tileY, tileZ);
}

Also, cheers Whov and Mastodon, I'll slice and dice checkConnections() myself too (11:50 am here, so plenty of the time left in the day for me)

LordMastodonFTW · August 25, 2014

Also, I think that something you should try to do is integrate the visual code and the mechanical code, so that automatically when it creates a visual connection it creates a mechanical connection. This is what many big name mod authors do, and it seems to work great, so maybe try it out instead of hardcoding every single possibility of connection, try that. Some pseudo code:

Your render class:

public void visualConnection() {

//Your connection code here

}

public void onVisualConnection() {

if(visualConnection == true) {

mechanicalConnection();

}

public void mechanicalConnection() {

//Your mechanical connection code here

}

This way, whenever you make a visual connection, a mechanical connection automatically gets created. I probably did not make that realistic, but then again it's pseudo code from a dev.

Minothor · August 25, 2014

I'll admit that I'm loathe to do that, while it could have offload some processing to clients, it also relies on the renderer being called for the connections to be functional.

I'm going to look into the tesselator now and scrap most of my old code by the way. It also adds in some interesting possibilities for efficiency.

Whov · August 25, 2014

public class test extends TileEntity {

public boolean[] connections = new int[]{0,0,0,0,0,0};

public void checkConnections() {

ForgeDirection dir;

TileEntity tile;

for (int i=0;i<6;i++) {

dir = ForgeDirection.getOrientation(i);

tile = this.worldObj.getTileEntity(this.xCoord+dir.offsetX, this.yCoord+dir.offsetY, this.zCoord+dir.offsetZ);

if (tile==null) {

connections = 0;

} else if (tile instanceof test) {

connections = 1;

((test)tile).connections[ForgeDirection.OPPOSITES] = 1;

}

Might work?

Didn't really think of that, thanks for bringing that up. In that case, it is probably not a good idea to do it specifically the way I pseudo coded it, maybe have the renderer rely on the mechanical connection, but it probably would be a good idea to find some way to get the code to realize that in the event of either connection not happening, make it happen so that things work.

Minothor · August 25, 2014

Thanks for the suggestion Whov, but since moving over to using direction Enums, I've kind of gutted the old code for now, this recode should also support "compound directions" too, or in other words, Diagonally connecting pipes.

Cheers again for the suggestion of using Tessellator instead, it's proving a little hit&miss to rebuild the model but definitely worth it. I'll repost here with news of either success or failure with this recode.

Minothor · August 26, 2014

Warning: Code Flood Incoming Below

I've torn apart the code and rewritten a lot of it, by and large, it's cleaner and stabler, but I am getting a really strange bug now.

If I check the number of connections on a pipe block, it seems to spawn with 6 connections in it's list even with no blocks around it and this is hampering my efforts to test individual pipe rendering directions working together.

Just to clarify, the rendering I can now handle fine, it's the weird connection list behaviour that's confusing me now.

Have you looked closely at the code that spawns the pipe? Maybe you accidentally did something wrong?

Minothor · August 26, 2014

The only thing I can see that's obvious is that I forgot to stop the pipe from including itself in the connections, but even after I changed the checkConnection code to ignore the centre block:

boolean centre = (x==0)&&(y==0)&&(z==0);
				if(target.hasTileEntity(target.getDamageValue(worldObj, xCoord+z, yCoord+y, zCoord+z))&&MFHelper.checkConnectable(worldObj.getTileEntity(xCoord+z, yCoord+y, zCoord+z)))
				{
					if(!centre){
						boolean twoWay = (worldObj.getTileEntity(xCoord+z, yCoord+y, zCoord+z))instanceof I_MFCable;
						formConnection(twoWay, x,y,z);
					}
				}

It's still returning 4 connections

EDIT: Changed the check to be inside the formConnection() function, it now disregards any that have x,y,z all set to 0.

Still struggling to find all the pipes though, it only appears to be detecting pipes that satisfy these relative conditions:

(y<0, x>0, z>0)

any ideas what's going on?

LordMastodonFTW · August 26, 2014

I think this may be because you do not have any -'s in your code. There are only +'s, so the code does not register the -'s.

Minothor · August 27, 2014

Cheers for the suggestions and help everyone, after swapping over to Tesselator and handling directions in a class similar to an ENUM I've managed to get it working, the Renderer is a bit of a mess of "if()" statements though, but for now it works:

Fixed Abstract Class for PipeDirection (saving and loading to byte array for the NBT was the main issue)

package RPower.api.power.cable;

protected int[] target = {0,0,0};

public A_PipeDirection(int xOffset, int yOffset, int zOffset) {
	int[] targetArr= {xOffset,yOffset,zOffset};
	setTarget(targetArr);
}

//TODO: Solve why connections of Y= 1, X&Z=0 evaluate to -89 instead of 111.

public A_PipeDirection(byte b) {
	System.out.println("["+b+"]");
	//y = b/100 (nearest whole)
	int yOffset = (byte)b/100;
	System.out.println(b+" yO:"+yOffset);

	//remove the processed value from the byte
	b-=(100*yOffset);
	System.out.println(" "+b);
	if(b<0)
		b*=-1;
	//x = (b/10)-1 (again, nearest whole and convert 0-> -1, 1 -> 0, 2 -> 1)
	int xOffset = (b/10)-1;
	System.out.println(b+" xO:"+xOffset);
	//remove the processed value from the byte
	b-= (10*(xOffset+1));
	System.out.println(" "+b);
	//z = b-1 (converting 0-> -1, 1 -> 0, 2 -> 1)
	int zOffset = b-1;
	System.out.println(b+" zO:"+zOffset);
	int[] targetArr= {xOffset,yOffset,zOffset};
	setTarget(targetArr);
}

@Override
public void setTarget(int[] target) {
	this.target = target;

}

@Override
public int[] getTarget() {
	return target;
}

@Override
public byte toByte() {
	byte modifier = (byte) (target[1]<0?-1:1);
	//=(100*y)+(10*(x+1))+(z+1)
	byte xRef = (byte) ((modifier*10)*(1+target[0]));
	System.out.println("Byte xRef:"+xRef);
	byte yRef = (byte) (100*target[1]);
	System.out.println("Byte yRef:"+yRef);
	byte zRef =  (byte)(modifier*(1+target[2]));
	System.out.println("Byte zRef:"+zRef);
	byte result = (byte) (zRef+xRef+yRef);
	return result;
}

Also, I'd recommend changing the texture to a slightly darker color, because it's burning my eyes, and I don't think your friends really want burnt eyes.

Minothor · August 27, 2014

that's more a combo of the solid-colour testing texture and lighting glitches and I'll tweak those once I've got the mechanics verified.

LordMastodonFTW · August 27, 2014

Proboably a good idea

Minothor · August 27, 2014

hitting a new bug now I'm afraid, remotely calling the breakConnection() function on adjacent pipes sometimes leaves open ended connections towards the removed pipe.

Try adding -'s sometime. It helps, believe me.

Minothor · August 27, 2014

Please could you elaborate on that? I'm looking through the break connection code and I'm inverting the relative coords in all the right places as far as I can see.

LordMastodonFTW · August 28, 2014

As far as I could see, you only had things such as Xcoord + x, no Xcoord - x anywhere. I think this may be your problem, but if it is not, then I am completely out of suggestions.

Minothor · August 28, 2014

Ah, yeah, that's because the x value is the relative value from -1 to 1,

so xCoord + (-1) is the same as xCoord -1.

I'm thinking of adding a cleanUp() function that can be marked to run on block update, see if that helps.
