Ice2670

Thank you all for helping me! However none of the things you said fixes the problem. But after I insert 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?

Got it, Thank you very much!

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.

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? ---- Minecraft Crash Report ---- // My bad.

Thank you!

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

Thank you all for replying, I'm trying on those suggestions and will post new code if the problem gets solved

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: ---- Minecraft Crash Report ---- // Shall we play a game?
