 Description   

Dispensers and droppers will not be activated by either redstone blocks or redstone torches.
They do get activated by other sources.

I placed TNT down and then a redstone torch next to it, on the same level.

What I expected to happen was
TNT blows up.

What actually happened was
The TNT did not ignite, but when I triggered a block update of the torch (by placing another torch next to the original and diagonally from the TNT), it did ignite.

How to replicate
1) Place TNT on a flat area of ground
2) Place a redstone torch or block adjacent to the TNT - even on all 4 sides.
3) Note that the TNT does not ignite.
4) Place a torch next to the original(s) (but not a block, this will not trigger an update) Relative position to the TNT does not matter upon further testing
5) Note that the TNT now ignites.

How this should be fixed
Ensure that TNT receives block updates from redstone torches and blocks as soon as they are placed, instead of waiting for them to send one. This does not occur with doors or pistons, which are also redstone-activated device, so something has not been copied over.

ffs Dinnerbone, hurry up and fix this before 1.5!

Comment by Ry [ 23/Feb/13 ]

I added another pic. the bottom doesn't update eather.

Comment by Daniel [ 18/Feb/13 ]

Confirmed in 13w07a

Comment by Callum Evans [ 18/Feb/13 ]

I can confirm in 13w07a.

Comment by Jared Jeyaretnam [ 14/Feb/13 ]

Once again. Make this 12w07a. And get this fixed, Dinnerbone, this is a major problem! One of the ways most people set off TNT is through redstone torches, not flint and steel.

Comment by Jared Jeyaretnam [ 31/Jan/13 ]

Someone update this since it's not fixed in 13w05a

Comment by Jared Jeyaretnam [ 29/Jan/13 ]

@Marcono1234 but we're also talking about redstone blocks here.

Also I think Kevin may be referring to a torch on the side of a wall, above the block.

Comment by Kevin Reid [ 29/Jan/13 ]

Got to disagree with you there. Build a pillar, place a TNT or dispenser against the side, and place a redstone torch on the pillar directly above. In 1.4.7, this will activate the TNT or dispenser; in 13w04a it will not (— if I correctly recall my previous testing).

Comment by Marcono1234 [ 29/Jan/13 ]

@Kevin Reid: No, it was always, that a redstonetorch above a block isn't powering the block.

Comment by Kevin Reid [ 29/Jan/13 ]

This bug also occurs when a torch is placed immediately above or below the block.

Comment by Marcono1234 [ 27/Jan/13 ]

Same thing on powerd dispensers:
1.The dispenser get powered = shoot arrow
2.A block is placed next to the dispenser = shoot arrow

This is also a block update bug

Thanks

Comment by Jared Jeyaretnam [ 27/Jan/13 ]

Could either the reporter or a mod copy some of the more detailed info from MC-8478? That way when this gets assigned to a mojangsta they'll have more to work on.

Comment by A Y [ 26/Jan/13 ]

For me it makes no sense ...

Comment by Tails [ 26/Jan/13 ]

For feature suggestions/changes please use the MineCraft Forums: Suggestions.

Comment by Marcono1234 [ 26/Jan/13 ]

@Tails: Is here also some kind of forum where you can write things which are missing now?

Comment by Marcono1234 [ 26/Jan/13 ]

Oh ok sorry

Comment by Tails [ 26/Jan/13 ]

No actually, pistons, command blocks, any kind of doors work for some reason...

Comment by Marcono1234 [ 26/Jan/13 ]

@Tails maybe everything which can be powered by redstone

Comment by Cody Shearer [ 25/Jan/13 ]

I found out that if you place 2 torches beside the TNT and break one of them that the TNT will ignite.

Comment by Tails [ 24/Jan/13 ]

Noteblocks.

Comment by Tails [ 24/Jan/13 ]

...and TNT.
