Implementing Health And Damage - Developing Games With Ruby - page 108

Target practice
But what if we blow ourselves up by shooting nearby? We would still be able to move
around. To fix this, we will simply cut out player input when we are dead:
class PlayerInput < Component
# ...
def update
returnif object . health . dead?
# ...
end
# ...
end
And to prevent tank from throttling forever if the pedal was down before it got killed:
class TankPhysics < Component
# ...
def update
if object . throttle_down && ! object . health . dead?
accelerate
else
decelerate
end
# ...
end
# ...
end
That's it. All we need right now is some resistance from those brain dead enemies. We will
spark some life into them in next chapter.
