»Anyone here pro at command blocks? Maybe some help :)

Soga, Is there any way to detect specific blocks? For example, I placed an oak wood and the block detector detected it, and it activated a command. But when I place any other block except oak wood, nothing is going to happen.

 

One block area or large area?

 

uhm, just one block, I can make proximity detector to make it large

 

Ok, you can detect a block pretty easily
Write /testforblock <x> <y> <z> <block name> to command block.
For example, /testforblock 813 68 134 planks
Then put redstone comparator next to command block.
NOTE: Redstone comparator output is 1, so put repeater.

 

I'm good at command blocks, but it's impossible unless you stand on top of every block you place. You can do /execute ~ ~-1 ~ (Block) 0 /(Comand)

 

/testforblock...

 

If you use testforblock you need 2 commands, but if you use execute it's just one command block.

 

Oh, okay, now I get it.
I added a redstone clock to make the command alive

 

I know. But I think he wants to detect a block in the area, not under the player.

 

@Soga btw, have you seen my Flora kit suggestion?. I want to create that kit using command blocks. The specific flowers can emit potion effects at a certain block radius, is that possible? Uhm I made one with player proximity detector and it worked, even without the flower. But I want to activate the command only if the flower is planted, and it will not work if the flower gets removed

 

OMG, lemme get the map

 

Making these kinds of kits by using command blocks is difficult, so it's not perfect.

well, idk too much about command blocks but this guy may know a lot:
