Help with RayTracingResult

Hey there,
i try to check if a player is looking at a block or not. I found some pages about working with RayTracing but i still don't understand how to work with it. For testing i created a command but i always get errors.

Here is my RayTraceCmd class:

Code:

public class RayTraceCmd implements CommandExecutor {

    @Override
    public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
        if(sender instanceof Player){
            Player player = (Player) sender;

            RayTraceResult result = player.getWorld().rayTraceBlocks(player.getEyeLocation(), player.getLocation().getDirection(), 10);
            if (result == null){
                player.sendMessage("nothing");
            }else {
                player.sendMessage(result.toString());
            }
        }
        return true;
    }
}

Error (open) Error (close)

Maybe someone can help me out.

Ah yes, that's the problem. Thank you. I forgot to change the API when changing versions.

But still: is there an option to check if a player is facing a block or not?

 

@funtastisch for check if a player is looking at a block, you can use getTargetBlock(). You can specify a range for the distance
