Skript: Block Detection

[DroidVengeance]

I noticed using "block behind" is no longer working.

on place of wall sign:
        if block behind event-block is a chest:
                do this...

Now has to be "south of" instead of "behind":

on place of wall sign:
        if block south of event-block is a chest:
                do this...

No errors in the console
Addons - skUtilities, SKQuery

Can someone else confirm?

[ShaneBeee]

I can confirm this.
In 1.12.2 (Skript dev37c) the block behind is the chest
in 1.13 (Skript alpha 3) the block behind is air, yet the block infront is a chest. Therefor showing that the direction appears to be reversed.

I'm not sure if this is an error. Behind now points towards negative Z axis, which makes sense. I'm not sure why exactly it'd point to south before, honestly.

Skript 2.3-beta1
Paper 1.13.1-b355

on break:
    cancel event
    loop blocks in radius 1 of event-location:
        loop-block is wall sign:
            send "Event: %event-location%"
            send "Loop: %location of loop-block%"
            send "Behind: %location of block behind location of loop-block%"

If wall sign facing south then the event-location is the location of the bock behind the location of loop-block but if the wall sign facing west, east or north the block behind the loop-block become air and not the event-location.

Im not sure if my explanation is accurate but I can say this, actually the expression "behind" means "-1" on the Z axe (in the 1.13 release) so I trying to use facing expression but I got an error:

on break:
    cancel event
    loop blocks in radius 1 of event-location:
        loop-block is wall sign:
            send "Event: %event-location%"
            send "Loop: %location of loop-block%"
            send "Behind: %location of block behind location of loop-block%"
            send "Facing: %facing of loop-block%"

And yes, I know, my english is bad ^^

[TheLimeGlass]

When testing on a block, the behind should return the opposite of the block facing, only if the block has a facing. That makes logical sense, if it doesn't have a face use the standard it has now. Less prone to user misunderstanding this way.

Main problem is that the direction is calculated with support of Entity, so it's all using calculations rather than just using BlockFaces for blocks.

[Blueyescat]

Works fine on 2.4-alpha3

[Blueyescat]

Sorry, i tested this again after i read @weberlepecheur's comment and yeah the issue is not fixed. Looks like using behind works like using north, no matter the block has a facing

[TheBentoBox]

I was kinda surprised to hear this was fixed.

For context of how this could work in 1.13+, I implemented something like this in skript-mirror (except the opposite, the block in front instead of behind) and it was simple:

block property faced block:
    return type: block
    get:
        set {_direction} to try expr-1.getBlockData().getFacing().getDirection()
        if {_direction} is set:
            set {_facedLocation} to expr-1's location ~~ {_direction}
            return block at {_facedLocation}
        else:
            return
