Would anyone help on a crash with block state storage?

So here's the problem, I made a cannon block that fires projectile when right click on it. The power of projectiles depend on how many iron blocks attached behind the cannon. Every thing works except when I reload the saved world and right click on that cannon block again, the game crashes. There will be no crash if I replace the old cannon block with a new one. And if I do not quit the game but just reload the world after quit, there will also be no crash. I suppose it has something to do with block state storage, but really don't know how to fix it. The crash report is as follow:

Don't use fields like these

    TileEntity tileentity;
    TileEntityPlasmaCannon plasmacannon;

in your block to assign a tile.... blocks are singletons so all blocks will use the same tile then... just use World#getTileEntity and cast it to TileEntityPlasmaCannon...

Also, I seriously hope all those special cased directions are a joke. EnumFacing specifically exists so you can do for example BlockPos#offset(EnumFacing).

Would you please show me an example of how to use forge block.hasTileEntity to create tile entity?

Gasp. So easy.

So I now use hasTileEntity instead of ITileEntityProvider, but the same issue still exist. I'm thinking maybe it's because I pass the block state to tile entity only when I place cannon block, so when I quit the game that state gets missing. So is it possible to let the world replace the old cannon block with a new one every time i reload the game?

Could you be more specific? I'm new to java and forge modding so I might lack of fundamental understanding on forge modding. By the way do you mean I should use  World#getTileEntity in onBlockAdded not onBlockActivated? cause I did not use instance fields in onBlockActivated.

if(this.plasmacannon == null)
{
    this.plasmacannon = (TileEntityPlasmaCannon) worldIn.getTileEntity(pos);
    plasmacannon.getstate(state);
}

in onBlockActivated, the game won't crash, but the tile entity stops updating. So the problem might be every time i reload saved world, my tileentityplasmacannon stops updating. But I really don't know how to fix that. Could this problem relates to tile entity registration?

You are still using instance fields... you need something like this... all local variables

TileEntityPlasmaCannon tile = (TileEntityPlasmaCannon) worldIn.getTileEntity(pos);
tile.getstate(state);

I'll try to explain singletons a bit... I don't know if everything will be correct but basically... a singleton is only one instance of a class, which means that all blocks only use that one instance instead of a new instance for each block, so all instance fields (the variables of the class) are shared between blocks, for example in your code... you're assigning the tile entity of only one block to the field... which means all the other blocks would use that same tile entity since they share all instance fields, thats why you have to do everything in the methods you override. So when you place another block, that tile entity field would be changed and the block placed before wouldn't function correctly.

if i make TileEntityPlasmaCannon tile local, than i will have to make another tile in onBlockAdded and that will crash the game. so i cannot use 2 different local tile in onBlockAdded and onBlockActivated.

it will not crash the game... you're just getting the tile from that location, the tile was already created before onBlockAdded, onBlockActivated... etc

I don't understand how is the tile already created before onBlockAdded, onBlockActivated? I mean you cannot create tile without pos but the only 2 methods that have pos are onBlockAdded and onBlockActivated. And by the way, I already tried make the tile all local, and when i right click on the block the game crashes.

its something with your fireplasma method then... need a crash report. Tile gets created together with the block. what you’re doing with World#getTileEntity is just getting the tile entity that is on that pos

its something with your fireplasma method then... need a crash report

I still think whether the tile is local or not is not the problem, it's just every time I reload the saved world, the update method in TileEntityPlasmaCannon will stop working. Because even if i do not quit the game, reloading the saved world will make powerfactor unchangeable.

Because your instance fields are not saved. Because they shouldn't exist at all. 

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.
