[1.7.10][SOLVED] Only drain to specific Tiles

[Muramasa]

Hi there,

 

I'm working on GregTech 5 Unofficial and I want to implement the mechanics that only specific Tiles (That implement IFluidTank) can only store Plasmas. I can stop these tiles from filling with fluid, as I don't need to know what tile is trying to transfer fluid to the machine, but not for drain.

 

Is there a way to get the Tile trying to drain fluid from a tank? I suppose I could check the blocks around the machine, but someone could just place a plasma-compatible pipe next to the machine and drain from a BC wooden pipe.

 

Thanks for looking, Mura.

I'm not entirely sure what you mean by this:

I'm going to assume you're talking about "specific Tiles" that you're adding. You may be interested in implementing IFluidHandler rather than IFluidTank, because the handler is what pipes connect to, and the handler methods include ForgeDirection arguments, so you know which side of the block is being drained from, so you can check the TileEntity on that side.

 

If I understand the bit with BC wooden pipes correctly, you're worried that one could use a plasma-compatible pipe as an intermediate, which you don't want. To solve this, just add the same logic you'd have in the machine to your plasma-compatible pipes.

 

Hope this helps.

His thing about wooden pipes was actually because he didn't know what side to check and if the player puts a wooden pipe on one side and a plasma-containment-pipe on another side, the fluid could be drained via the wooden pipe "because a plasma containment pipe exists."

 

Changing to the sided version fixes the problem.

Yeah sorry, I should of been a little more specific. I didn't know the drain method in IFluidHandler has a direction parameter, so thanks a lot for pointing that out. That will most likely solve the problem.

 

The only thing I'll have to look into though is how this effect the machines in GT, but I'll mark this as solved for the moment until I get around to testing it.
