C/C++代写 - SJSU - CS 134 – Game Design Programming Project 3 – Final Project
时间:2020-12-03
In this final project, you will create a substantial portion of a
3D Lander-style game from scratch in C++ using the components you have worked on from pervious
assignments including lighting, physics, octree subdivision, particle simulation and more. The
player will be able move the “vehicle” using physics
and thrust forces to control landing of the
spacecraft on a highly detailed terrain model. The
player will have control over the motion of the
craft, camera views. Upon successful decent, the
game will do collision detection between the craft
and the surface of the planet while the player
touches down. Accompanying sounds will enhance
the experience. The example shown in class is a
“Lunar Lander” style, but you can customize the
experience to any type of vehicle-terrain
interaction game if you meet the technical
requirements.
Game Play
The player is given two minutes of fuel. Fuel is exhausted only when the thrusters are on. When the
fuel is exhausted, the thrusters no longer operate. The amount (in time) of unexpended fuel must
be displayed in viewport. The LEM pilot must land the spacecraft (in moon gravity) in the designated
high-resolution landing area on the 3D terrain. If the landing is too hard (as measured by the
contact forces), the spacecraft will explode (a 3D explosion will catapult the ship away
uncontrollably). This will signify that the game is over. If the ship lands safely in the landing zone,
the player wins.
Required Functionality
The required technical requirements for the project is as follows:
• The LEM must be able to maneuver (left, right, forward, back, up/down and rotate along it’s UP axis)
using thrust force using a full physics simulation (which includes thrust, gravity and turbulence forces.)
This was covered completely in the midterm for the 2D case. You need to add another dimension. A
non-physics way of moving or a hacked physics implementation will not receive credit. Students can
choose to write a custom simulator as we did on the midterm or use the particle simulator example.
Since the particle simulator supports external forces, this may be an easier starting point.

• The craft will be equipped with a telemetry sensor to detect altitude (AGL) above ground level and
display it on the screen. You must use ray-based collision detection to accomplish this ask. The ray must
intersect the 3D terrain. The feature should able to be turned on/off with a hotkey.
• The ship must use a particle emitter for the rocket exhaust. A particle emitter must be used for the
explosion.
• Particles must be rendered using a shader otherwise it will be too slow. An example will be given in
class.
• The ship must be able to do full collision detection with the terrain (including mountains and landing
area). If the ship contacts the terrain, the collision must be resolved with a suitable impulse force that
can be demonstrated. You are only required to have one (1) bounding box on your vehicle, but your
terrain should be spatially partitioned using an octree. Your demo video must show collision with the
landing area AND mountainous terrain to prove that it is reliable.
• Use lighting techniques learned in class to light the landing area scene using OpenGL lighting (ofLight)
using at least three (3) lights. Adding an additional light on the spacecraft that can be turned on/off is an
interesting effect.
• The player should be able to switch between multiple camera views which include a minimum of:
o o A “tracking” camera that stays aimed at the spacecraft from a fixed location.
o o One onboard. Can be aimed in different directions, depending on your scenario.
o The player will also have to have access to the EasyCam camera to be able to navigate anywhere
they like over the surface.
o The EasyCam camera should have an option so that you can retarget the view to a point or the
spacecraft.
• Sound is required for effects (spacecraft thrust) and any background sounds you would like.
• For diagnostic purposes, you should have a feature (such as in the) to be able to manually move the
spacecraft around the scene using the mouse directly and then start your game from that position.
• The scene should have a simple 2D image background (such a starfield).
• Your game trailer will be graded as part of the project and must show all features. If a feature is missing
from the trailer, we will assume that it is not implemented and it won’t be credited.
• All code and assets required to build and run the game must be submitted. If your game doesn’t compile
and run or features that are shown in the video do not match the source provided, you will not receive
credit for the project.

Suggested Steps/Hints
Even though the project seems complex, you have already completed most of the technology and R+D needed
for the game:

• Consider using simple particle motion to move the spacecraft and add an additional integrator for
rotation in “Y”.
• Use the class particle system to generate a thruster simulation.
• Use the octree code you developed for altitude tracking and collision detection.
• Use the octree code for any 3D selection you may want to do on the surface.
• It will be required to exercise wise time management to complete the project with a good level of
quality.
Substituting Content
If you are interested in substituting content and creating your own “theme” of a game, you can but it must meet
the same technical requirements.
• Create your own “vehicle” and/or terrain in Maya (or
modeler of your choice). If you choice to use an existing
model, copyright laws apply.
• Terrain must be at least 200K vertices and contain
interesting features. (not just flat plane ).
• still required to provide a custom emitter that produces a
exhaust-like effect of your choice even if the vehicle of
your choice doesn’t have a rocket engine.
• Source for example image at right:

What to Submit
1. Submit the game code in canvas. Do not include your trailer in the .zip file. You must sign each
module or function that you develop in the code. Source must be submitted in the
_Project3_.zip format.
2. You must submit a trailer to the link to a gallery to be provided and to the Canvas assignment.. The
trailer must be a screen capture with sound with no product watermarks. No screener movies with an
phone camera will be accepted. The trailer should be one that you are proud of and can refer to in
your portfolio or project listing on your CV.

Grading Criteria
A rubric will be provided in the assignment on Canvas. Grading will be passed on the list of requirements in this
document. The trailer will also be included in the grading (important).
Collaboration
Students can ask questions on the Discussion section of the class in Canvas, share ideas and programming
information, but you cannot share source code. Each student must create and submit their own unique
solution to the game.
