Fill both blanks to create a dictionary of animation states and their durations.

Unity

Dictionary<string, float> animationDurations = new Dictionary<string, float>() {
    {"Run", [1],
    {"Jump", [2]
};

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

Using integers without 'f' suffix

Mixing up durations for animations

The 'Run' animation lasts 1.2 seconds and 'Jump' lasts 0.8 seconds as float values.

5fill in blank

hard

Fill all three blanks to create a dictionary comprehension that maps animation names to their lengths if length is greater than 1 second.

Unity

var longAnimations = new Dictionary<string, float>() {
    {"Run", [1],
    {"Jump", [2],
    {"Attack", [3]
}.Where(kv => kv.Value > 1).ToDictionary(kv => kv.Key, kv => kv.Value);

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