Question

scripts/ai/Dream.boo

import CultLib
import LonelyHero

class Dream(Enemy):
    pass

C#

var bc = new BooCompiler();
bc.Parameters.Input.Add(new FileInput("rsc/script/ai/" + "Dream" + ".boo"));
bc.Parameters.Pipeline = new CompileToMemory();
bc.Parameters.References.Add(Assembly.GetExecutingAssembly());
bc.Parameters.References.Add(Assembly.LoadFile(new DirectoryInfo("CultLib.dll").FullName));
bc.Parameters.References.Add(Assembly.LoadFile(new DirectoryInfo("sfmlnet-audio-2.dll").FullName));
bc.Parameters.References.Add(Assembly.LoadFile(new DirectoryInfo("sfmlnet-graphics-2.dll").FullName));
bc.Parameters.References.Add(Assembly.LoadFile(new DirectoryInfo("sfmlnet-window-2.dll").FullName));

var cc = bc.Run();

if(cc.GeneratedAssembly!=null)
{
    cc.GeneratedAssembly.CreateInstance("Dream", true, BindingFlags.NonPublic, null,
                                        new object[] {Parent, pos}, null, null);
}
else
{
    foreach (var error in cc.Errors)
        Console.WriteLine(error);
}

In the line bc.Parameters.References.Add(Assembly.GetExecutingAssembly()); I add the executing assembly, which contains the namespace “LonelyHero”. However, the error

rsc/script/ai/Dream.boo(2, 8): BCE0021: Namespace LonelyHero not found. maybe you forgot to add an assembly reference?

appears.

LonelyHero should exist, why does this error occur and what can I do to resolve it?

Note:
Upon replacing Assembly.GetExecutingAssmebly() with Assembly.GetAssembly(typeof(Enemy)) , thus assuring it adds the assembly with a class under the LonelyHero namespace, the same error occurs. Also with Assembly.LoadFile(new DirectoryInfo("LonelyHero.exe").FullName)

Occurs in Boo 0.9.4.9 and booxw-1203

Answer 1

Imported namespaces in BOO need to contain at least one public type for the import to succeed; otherwise you will get the BCE0021 error, so you want to make sure the Enemy type is public (or another one).
