💡 Hint

Common Mistakes

Forgetting to put quotes around the action name.

Using a variable name without quotes.

The InputAction constructor requires the name as a string, so it must be in quotes.

💡 Hint

Common Mistakes

Calling start() instead of enable().

Using activate() which does not exist.

To start listening for input, you must call the enable() method on the InputAction.

💡 Hint

Common Mistakes

Using int which is not suitable for analog input.

Using string or bool which are invalid types here.

The ReadValue method should use float to get the input value as a floating-point number.

4fill in blank
