How to do it...
We will start by making some updates to the
GameCharacterControl
class. For the
GameCharacterControl
class, we introduce two new variables,
cooldownTime
and
cooldown
:
1. The first is the time between shots.
2. The second is the current countdown until the character can fire again. We need to
add a getter for
cooldown
and the value itself is set in the following
onFire
method:
public void onFire(){
cooldown = cooldownTime;
}
3. Lastly, in the update method, we need to subtract
cooldown
by
tpf
if it's more
than zero.
In
InputAppState
, we also have to make some changes:
1. We begin by introducing a
List<Geometry>
called
targets
. This is the list
of things the fired rays will check for collisions against. In the
addInputMap-
ping
method, add another mapping for
Fire
. A suitable button is the left mouse
button. This is implemented as follows:
inputManager.addMapping(InputMapping.Fire.name(), new
MouseButtonTrigger(MouseInput.BUTTON_LEFT));
2. In the
onAction
method, change the logic slightly. We add a new check for the
fire action and we put the existing logic inside the
else
clause. We're telling
character
to handle all actions, except when we fire. This is implemented as
follows:
if (name.equals("Fire")) {
if (isPressed && character.getCooldown() == 0f){
fire();
}
} else {
