Instance Names

Review

We can differentiate between multiple copies of the same object using Instance Names. Each instance of an object has it's own properties (like tint, X position, Y position) separate and independent from other objects.

What We Did

1. Assigned a copy of ball_mc the instance name ball1
2. Created another instance of ball_mc and named it ball2
3. Tinted ball2

Self-Check for Understanding

Why would each of the following make bad instance names:

1. Stage
2. two cats
3. 2cats
4. cat;blue

Highlight to find out the answers:

-->
1. Stage is a reserved name (Flash has something called a Stage already)
2. There is a space in the name
3. The name starts with a number
4. The name contains a semicolon (other than an underscore, no punctuation is allowed)
