[1.15.2] New sticky block for piston

[Corgam]

Hi,

I would like to add a new slime block to the game, which works in a simular way to the original slime block, that is: it can move other blocks around and other slime blocks of the same type, but not other sticky blocks (honey blocks).

I found two functions in IForgeBlock file:

 

default boolean isStickyBlock(BlockState state)
{
   return state.getBlock() == Blocks.SLIME_BLOCK || state.getBlock() == Blocks.field_226907_mc_;
}

 

default boolean canStickTo(BlockState state, BlockState other)
{
        if (state.getBlock() == Blocks.field_226907_mc_ && other.getBlock() == Blocks.SLIME_BLOCK) return false;
        if (state.getBlock() == Blocks.SLIME_BLOCK && other.getBlock() == Blocks.field_226907_mc_) return false;
        return state.isStickyBlock() || other.isStickyBlock();
}

Is there a way to replace them and add the new block to the functions so they also check for it?

Or is there another way to do that?

 

Cheers,

Corgam

Override the methods in your Block class and make them return true.

It works but only in one way. When slime and honey blocks are pushed they don't move the new slime block, but when you try to push the new slime block with the piston is moves normal slime block and honey with it. 

Any idea how to fix that?

I think I would need to override canStickTo() methode in normal SlimeBlock and honey block, but how can I do it, If I cannot modify the vanilla code?

I think you need to leave the default implementation of canStickTo, just override isStickyBlock

Unfortunately no, isStickyBlock makes that it can move other blocks (all of movable blocks), but doesn't prevent it from sticking to another slime block or honeyblock.

canStickTo makes it that other sticky blocks cannot move it, but as for now I didn't find a way to stop the new block from moving other sticky blocks while being moved. (so it works only one way)

Oh, re-reading the code, I think you need to override canStickTo to only return true if the other block is itself or non sticky. To be honest, I'm surprised that slime doesn't push your block.
