💡 Hint

Common Mistakes

Using private or non-void methods.

Using Unity lifecycle methods like Start or Update which are not called by animation events.

The method name 'OnAnimationEvent' is a common choice for animation event handlers. It must be public and void with no parameters to be called by animation events.

💡 Hint

Common Mistakes

Passing the method name without quotes.

Passing a float value instead of a string.

The functionName property requires the method name as a string, so it must be in quotes.

Fix the error in the method signature to be compatible with animation events that pass a float parameter.

Unity

public void OnEventTriggered([1] value) {
    Debug.Log($"Value: {value}");
}

💡 Hint

Common Mistakes

Using int or string instead of float.

Not matching the parameter type with the animation event.

Animation events can pass a float parameter, so the method must accept a float argument.

4fill in blank

hard

Fill both blanks to create an animation event that calls 'TriggerEffect' at 2 seconds.

Unity

AnimationEvent event = new AnimationEvent();
event.[1] = 2.0f;
event.[2] = "TriggerEffect";
clip.AddEvent(event);

Drag options to blanks, or click blank then click option'

Dduration

💡 Hint

Common Mistakes

Using 'name' or 'duration' which are not valid properties for animation events.

Mixing up the properties.

The 'time' property sets when the event triggers, and 'functionName' sets which method to call.

5fill in blank

hard

Fill both blanks to define a method that receives a string parameter from an animation event.

Unity

public void [1]([2] message) {
    Debug.Log($"Message: {message}");
    // Additional logic here
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using int instead of string for the parameter.

Using a method name that does not match the animation event.

The method name 'DisplayMessage' is a valid choice. The parameter type must be 'string' to receive string data from the animation event.
