Disney Infinity Play Lab - Events

PopCap games founder John Vechey introduces the concept of 'events' inside video games.

Now we're going to learn about something that
all game programmers use everyday. They're

called "events." An event tells your program
to listen for when something happens. And

then when it does, it performs an action.
Some examples of events are listening for

a mouse click, an arrow button, or a tap on
the screen. Here, we're going to make Baymax

move up to touch Hiro and move down to touch
Rapunzel when the player uses the up/down

arrow keys or the up/down buttons. We'll use
the "when up arrow" block and attach the "move

actor up" block to it, so when the player
presses the up arrow key, everything attached

to the "when up arrow" block is run. We'll
do the same thing to make Baymax move down.

Step by step your game is getting more interactive.
