Objective complete - mini debriefing
In this section, we created the
rocket
prefab and particle effects that will appear when
the player clicks on
fire
. It seems like we didn't see any progress in this section, but we will
definitely see the progress in the last step, so be prepared!
First, we created the
Explosion
particle system, which contains the
Flame
,
Light
, and
FireSmoke
elements. We also created the
AutoDestroyParticle
element to control
the time this particle takes to be destroyed from the scene. In this
Rocket
script, we also
controlled the intensity of the light related to the particle's appearance. We used the
In-
voke()
function to call the
KillObject()
function after the
timeout (4.0
seconds)
parameter.
Next, we created the
Rocket
script, we used
@script RequireCompon-
ent(ConstantForce)
in Unity JavaScript and
[RequireCompon-
ent(typeof(ConstantForce))]
in C# to tell the script to acquire the
Con-
stantForce
component for the
rocket
prefab; this will tell Unity to automatically add
the
ConstantForce
component when we add this component to the object.
Note
ConstantForce
is one of the
Physics
components in Unity that will add a constant
force to the
RigidBody
object (
ConstantForce
works with the
RigidBody
com-
ponents, so when we add
ConstantForce
to our object, Unity will automatically add
the
RigidBody
object as well), which will contain the properties that we can use to con-
trol the rocket's movements. For more detail, have a look at the following website:
In this script, we also checked whether the rocket collides with other objects in the scene.
This will trigger the script to instantiate the
Explosion
particle on the point that it collided
by using
ContactPoint
. Then, we created the
FireTrail
particle and attached to the
rocket
object.
Finally, we created the
Smoke
particle and attached it to the gun barrel, which will be
triggered when the player shoots and this will be done in the next step.
