Solved Line going red (dont know why)

So im making a double jump plugin for a server, and this is one of the lines:

Code:

&& (player.getLocation().subtract(0, 1, 0).getBlock().getType() != Material.AIR)

But it's underlined and i dont know why?
The errors:

Incompatible operand types org.bukkit.Matieral and net.minecraft.server.v1_7_r4.Material

 

Delete your net.minecraft.server.v1_7_r4.Material import and import org.bukkit.Material

Looks like you've imported the wrong Material. Remove the current import, then import the correct one (org.bukkit...). If you're using an IDE, hovering over the problematic line should give you a quick fix option.

Out of curiosity; did you even know the answer to this question when you first posted the "wat" picture, or did you edit your post to copy mine?

 

Cheers guys!

Before he edited the original post his error said the same thing as his code so no I didn't until he posted the actual error, but I did not copy you.

Ah, my apologies. I've seen few cases where people first come on the thread to troll (in this case, the picture), then later edit their post and copy someone's answer to make them look like they know something
