❌ Errors

Logic blocks are designed to be error-tolerant by default to reduce crashes in production. When an error occurs in an input handler, the logic block catches it internally to avoid halting execution.

You can easily override the default error handling behavior.

🚨 Customizing Error Handling​

[Meta, LogicBlock(typeof(State))]
public partial class MyLogicBlock : LogicBlock<MyLogicBlock.State> {
  ...

  protected override void HandleError(Exception e) {
    // Make this logic block crash on error.
    throw e;
  }
}

🚫 Adding Errors​

You have two options for engaging the error handling mechanism:

  • Throw an exception from an input handler. The HandleError method will be called, which does nothing by default unless you override it.

  • Call AddError(Exception e) from your state. This method also invokes HandleError and works well for non-critical errors if you don't automatically throw in the HandleError method.

How you handle errors is up to you.
