line 25 is the line with Sign sign = (Sign)event.getClickedBlock();

it would be great if any of you guys would be able to help me

 

Code:java

Sign sign = (Sign)event.getClickedBlock().getState();

Hope this helps!

 

Make it a try stament and add an exception at the bottom printing out a line saying Flag Error. The mess around with the code untill you don't see any more errors
AngryNerd I tried that and it doesn't work
And I also have trouble with this event I get the same error but I made it smaller by adding the exception.

 

nope it does work sign extends BlockState.

 

You want to make sure that the block is actually a sign as well:

Code:

if(event.getClickedBlock().getState() instanceof Sign) {
    Sign sign = (Sign) event.getClickedBlock().getState();
}

 

Also, don't check for type == Material.SIGN, that one should be Material.SIGN_POST
