Update block when specific metadata is reached?

[Gwafu]

Is there a function or a way that will be triggered when a block reaches a specific metadata (let's say 7)? UpdateTick() can't be used since it's random update within a chunk (?).

 

Any help is appreciated :>

updateTick()

 

And updateTick is only random if you have random ticks enabled.

 

You can also use onNeighborBlockChanged.

 

The answer to your question actually depends on the answer to another question:

 

When are you changing the metadata?

[Gwafu]

The idea is to have a block kind of 'flow' through metadatas.

 

When a water block is above the block, it instantaneously turns into meta=7 through onNeighborBlockChanged. When this block reaches meta=7, it will start 'flowing' into blocks (same block) perpendicular to it, slowly increasing its meta from 1 up to 7.

 

I haven't really coded it yet, it's just an idea. I might try using updateTick() (didn't know that information, thanks for the heads up :-))
