I have created AdvancedRobot. After first round in Run() I have got exceptions from Ahead method.

 public override void Run()
 {
        //...
        var moveAmount = Math.Max(BattleFieldWidth, BattleFieldHeight);
        Ahead(moveAmount);
        //...
 }

The exceptions are:

System.InvalidCastException: „Unable to cast object of type 'net.sf.robocode.dotnet.peer.ExecCommands' to type 'net.sf.robocode.dotnet.peer.ExecResults'.”

and

java.lang.Throwable; StackTrace „($exception).StackTrace”: „System.InvalidCastException” {System.InvalidCastException} Source "jni4net.n-0.8.7.0"

As a result my robot has a label "Disabled" and doesn't move. Have you got any ideas?

I use Robocode for .NET.

You need to add the source code for your `Ahead` method to the question – M Y Apr 10 '18 at 14:38
I use method from Robocode: http://robocode.sourceforge.net/docs/robocode.dotnet/html/42edc934-b4e1-0785-a8cb-5aecbc876d9b.htm – Kamil Apr 11 '18 at 16:31
where in your code do you set moveAmount? are you casting it to a double? – M Y Apr 11 '18 at 23:16
I updated the code – Kamil Apr 12 '18 at 06:43
try `var moveAmount = (double)Math.Max(BattleFieldWidth, BattleFieldHeight);` – M Y Apr 13 '18 at 11:30
it doesn't help – Kamil Apr 19 '18 at 08:19
