What just happened?
We have inserted certain properies in the game in which we can play with variables,
that is, send messages, to numerically change the properies of the objects. In our game,
we changed to a lower value of our character's life when a collision occurred. If you crash,
you lose some life, is it true? Here are some guidelines to do it:
Create a simple life bar model
Scale it in one axis with moion, insering the change in keyframes 1 and 100
Create a Property game called LifeP
