💡 Hint

Common Mistakes

Using non-existent methods like Move or GoTo.

💡 Hint

Common Mistakes

Using greater than comparison which is incorrect.

Checking equality which may fail due to floating point precision.

To check if the agent reached the destination, remainingDistance should be less than or equal to stoppingDistance.

4fill in blank

hard

Fill both blanks to create a dictionary of agent speeds for agents with speed greater than 3.

Unity

var fastAgents = agents.ToDictionary(agent => agent.[1], agent => agent.[2]).Where(kv => kv.Value > 3);

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

💡 Hint

Common Mistakes

Using destination or remainingDistance as dictionary keys or values.

Mixing up key and value properties.

Use 'name' as the key and 'speed' as the value to create a dictionary of agent speeds.

Using remainingDistance instead of speed.

Not converting names to uppercase.

Filter agents with speed > 5 and use their uppercase names as dictionary keys.
