Objects will now snap to any guides on the Stage.  Note: Choose View > Guides > Lock Guides to lock your guides. This prevents you from accidentally moving them. Clear all guides by choosing View > Guides > Clear Guides. Change the color of the guides and the snapping accuracy by choosing View > Guides > Edit Guides. 6 Drag the robot instance and the hero instance so their bottom edges align with the guide. Changing the Color effect of instances The Color Effect option in the Properties inspector allows you to change several properties of any instance. These properties include brightness, tint, or alpha. Brightness controls how dark or light the instance appears, tint controls the over- all coloring, and alpha controls the level of opacity. Decreasing the alpha value decreases the opacity and increases the amount of transparency. 98 Lesson 3 Creating and editing symbols
