💡 Hint

Common Mistakes

Using a method that does not exist like HasTag or CheckTag.

Comparing tags with == operator instead of CompareTag.

The method CompareTag checks if a GameObject has a specific tag efficiently.

💡 Hint

Common Mistakes

Using a method instead of a property.

Using incorrect capitalization.

The property layer returns the layer number of a GameObject.

4fill in blank

Fill both blanks to set a GameObject's layer to the layer number of the "UI" layer.

Unity

int uiLayer = LayerMask.[1]("UI");
gameObject.[2] = uiLayer;

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

CLayer

DGetLayer

💡 Hint

Common Mistakes

Using incorrect method names like GetLayer.

Trying to assign to a method instead of the layer property.

LayerMask.NameToLayer("UI") converts the layer name to its number. Then assign it to gameObject.layer.

5fill in blank

hard

Fill all three blanks to create a LayerMask for the "Enemy" layer and check if a GameObject's layer is included.

Unity

LayerMask enemyMask = 1 << LayerMask.[1]("Enemy");
if ((enemyMask.value & (1 << gameObject.[2])) [3] 0) {
    // GameObject is on Enemy layer
}

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

ANameToLayer

C!=

D==

💡 Hint

Common Mistakes

Using '==' instead of '!=' in the condition.

Not shifting 1 by the layer number.

Using incorrect method names.

Use NameToLayer to get the layer number, then check if the bitmask includes the GameObject's layer by using bitwise AND and comparing if the result is not zero.
