Pause Demo

What does it do?

It demonstrates how one can pause most aspects of the game; it uses "Scrolling Up" as a command to pause, and "Scrolling Down" as a command to unpause.

For doing so, it created a few animations which will be paused. The rightmost animation should not be paused.

For information about the animations, see the Animation Demo.

What are important aspects of the code?

These lines are key in this demo:

• game.AddSystem(&engi.PauseSystem{World: &game.World}), to add/enable the PauseSystem;
• engi.Mailbox.Dispatch(engi.PauseMessage{amount > 0}), to send a PauseMessage to the PauseSystem, indicating (un)pausing;
• d_entity.AddComponent(&engi.UnpauseComponent{}), to prevent the rightmost animation from being paused.
