Dynamically loading Assembly in Web Player

[anon57420914]

Hi all,

Within the editor, I am able to download a .dll using WWW, and instantiate classes from it with Assembly.CreateInstance(…).

When going to the web player, I see the following error in the log (my class/method names scrubbed to protect the innocent :)):

MethodAccessException: Attempt to access a private/protected method failed.
  at System.Security.SecurityManager.ThrowException (System.Exception ex) [0x00000] in <filename unknown>:0 
  at MyClass.myMethod (.Game game) [0x00000] in <filename unknown>:0 
  at StartLevel.Update () [0x00000] in <filename unknown>:0 

Is this possible in the web player? Is there a different/better method?

Here is the solution that is working for me:

• Download and load your Assembly with WWW

• Use the following code to load and instantiate a class from within that Assembly:

  Type myType = myAssembly.GetType(myTypeName);
  ConstructorInfo ci = myType.GetConstructor(new Type{Type.GetType(“MyConstructorArgTypeName”)});
  MyClass instance = (MyClass)ci.Invoke(new object{myArg});

(Sorry, I can’t seem to get that to format as code for some reason with leading spaces)

While I’m not quite sure why Assembly.CreateInstance would not be allowed in the web player, you should be able to use Assembly.Load. See the “Including scripts in AssetBundles” example here.
