QUESTION Introduction The term assignment is based on and adapted from a real-life project that is currently operational in Malaysia. Since you will be working with a real-life project, serious considerations should be given to your work. This is an exceptional opportunity for you to put together all that you have learned thus far, over and beyond the Project Management course. Project Background The ill-fated Automated Enforcement System (AES) has been given a new breath of life recently. AES Solution Sdn Bhd, a government-owned company under the Ministry of Finance Incorporated had taken over the two concessionaires contracted to set up the system (Beta Tegap Sdn Bhd & ATES Sdn Bhd). The re-implementation of AES reflects a serious move by the government to reduce road fatalities. While AES involves issuing summonses for the related traffic offences, its primary objective is to educate people to be good and responsible road users and ultimately reduce the number of deaths due to the road accidents. Your company, Prime Mojo Resources Sdn Bhd (PMR) has been recently commissioned by AES Solutions Sdn Bhd to resume the implementation of the RM700 million AES nation-wide projects. In addition to the those unit installed by the former concessionaires, PMR is to ensure the installation and roll-outs of AES at pre-identified 800 “black spots” throughout all the 4 main regions in the Peninsular as well Sabah & Sarawak within the next 5 years. The scope of the project includes leading a nation-wide public relation (PR) “roadshow with various government agency partners. Your Tasks You are to assume a role as a Project Manager for PMR Sdn Bhd, in providing overall leadership for the successful implementation of these AES roll-outs. As the budget release becomes more stringent these days, you are to prepare & submit the detailed Project Plan to the Project Sponsor (AES Solutions) & Partners (RTD, MIROS & PDRM), to be executed within the budget allocated & the project duration specified. Your Deliverables The plan/report must include the following components: • Introduction • Project Objectives/Goals • Project organization (team members & roles) • Responsibility Matrix • Risk Analysis – describe possible project risks, the likelihood of these risks arising & the risk resolution strategies developed • Required resources — people, equipment, materials & facilities needed to complete the project) • Project success criteria • Change control systems • Network Diagram/Gantt Chart & project milestone (MS Project/Excel) • Project closures (including lessons learnt) Your report should be of 12 to 15 pages, Arial & 1.5 spaced. You are free to make reasonable “assumptions” within the project context, to enhance your overall project report

Applied Maths and Physics for Games – Coursework 2 Specification and Mark Scheme Motion Physics for typical Game Scenarios Introduction You are to build a small set of 3D physics demonstrations using the Unity Game Engine that can perform a variety of tasks in 3D using vector maths and equation of motion . This can be implemented in the language of your choice (Javascript or C#) though C# is preferred. Note that you are allowed to use the transform of all the game objects but not the rigid body or any of the Unity Physics. You must use the Euler method (described in the lectures) for all of the problems. You can use the structure Vector but not its methods such as normalized etc. Note that for high marks your solutions must be complete (meet all requirements), well coded, reusable, be a realistic, and take into account the dimension of the game objects in collisions. See the grade descriptors in this document. Note that any mathematical symbols in bold are vector quantities. Task 1: Vector Maths – 25 Marks available You shall build and test a class library consisting of at least the following functions. Note in Unity you can use Vector3 as your basic 3D vector structure. See Appendix A. Function Max Mark3 % 3D vector addition 2 3D vector subtraction 2 3D dot product 2 Unit vector of a 3D vector 2 Vector reflection (axis aligned) 2 Polar to cartesian, Cartesian to Polar coordinates 3 Unit direction vector4 2 Magnitude of a 3D vector 2 Scaler multiple of 3D vector 2 Vectors nearly equal with radius 2 3D zero vector (0,0,0) 2 A point is on a line 2 Important Note: you should include at least one test for all these functions to get full marks in this section to demonstrate correctness in the functionality. Create a separate test script with hard coded test cases you can also use any built-in unit testing tools. Note you can use Debug.Log(…) to print your tests to the console. Also note you may choose to create more methods such as vector projection in order to help you solve the problems. Solve the following time- stepping problems using the Euler or similar method (see Appendix C) using your vector maths library: Task 2 – 10 Marks available – 3D Trajectory problem with restitution A) A trajectory in 3D (use a sphere) for a projectile that has a launch vector that can be set in design time. Time step = Time.deltaTime. The gravity vector is (0.0, -9.81,0.0). The initial position of the projectile can be anywhere in your scene. When the sphere lands (so y component of position very close to zero) then the sphere should bounce as though on a hard surface. See figure 1. Use a coefficient of restitution e that has a value that can be set at design time by using a public property on the script. Note that you need to decide when to stop the ball and this should be when the new bounce height (in y) is approaching zero. In other words, the vertical velocity after the bounce is smaller in than some tolerance (e.g. 0.01). Figure 1 Ball in motion for 3D trajectory Figure 2 Velocity setting Figure 3 Showing entry for restitution (bounciness) Task 3 – 15 Marks Available This task is to create a scene that demonstrates a path follow routine using vector maths (direction vectors). Set up four or more game objects (waypoints) anywhere in a 3D scene. Another game object (a sphere) travels from waypoint to waypoint continuously at a speed that can be set via a public property in the Unity script. Once the sphere is within a given distance to the waypoint, it should then move in a circle around the waypoint and then on to the next waypoint (5 points for this step). The radius of the rotation can be set as a public property – see Figure 5 Waypoint script settings. If your waypoints are labelled A B C D, then the order of travel shall be A B C D A and then repeat. The figure below shows an example scene with four cylinders as waypoints. Note that you must be able to move the waypoints to any location at design time and path follow with still work. Figure 6 shows the moving object’s public script properties. Figure 4 Waypoint scene Figure 5 Waypoint script settings Task 4: – 25 Marks Available A) Vector reflection and friction problem. Construct a plane surround by four solid walls. This is similar to the pool or snooker table and can be square or rectangular. Figure 6 show a stylised plane and four cubes stretched out to form the surrounding walls (think snooker table cushions to get the dimensions correct). For part A you only need one ball (sphere). Note that it is very important that the ‘table’ is aligned with the x-z plane exactly so that the boundaries and axis-aligned so that you can use simple axis-aligned vector reflection. Note that this is essentially a 2D problem and the y-component is not needed for the calculations (though is used to position the sphere on that table when designing). For the first part of the problem, you need to demonstrate axis-aligned vector reflection from the boundaries. To do this set up a sphere on the plane that can be assigned an initial velocity (z and x components only actually change). When the sphere hits a boundary, it should ‘reflect’ of both the vertical and horizontal boundaries realistically (angle of incidence = angle of reflection). To slow the ball down you need to add dynamic friction to the table which is a decelerating force, and this is the acceleration part of the problem (as the mass of spheres in the problem all equal 1). The friction factor can be varied at design time (see Figure 6) and friction is always acting as a force (so deceleration) in the opposite direction of the sphere’s velocity vector. In other words, to create the deceleration vector you need to get the unit direction vector of the sphere velocity, reverse it, and then scale that by the friction factor. Figure 6 Properties for the ball showing velocity setting and friction factor Figure 7 Textured scene for the vector reflection problem B) Extension to Task 3. – Maximum of 25 marks for handling the first impact and the case of collisions between two moving balls (15 marks if only the first collision is handled) – see Appendix D for the formula for this. You are to implement a two-ball collision at an arbitrary angle. Considering the scene in Figure 7 for the initial impact of the stationary red/target ball and cue ball, we have a white ball and red ball set up on the table. Using the code already created for part A, we can direct the white ball towards the red ball in the scene and because we control the initial velocity, we can hit the red ball at any angle. On collision the subsequent velocity vectors are dictated by the conservation of momentum a shown below. Note you can assume that the ball masses are equal so ??1 = ??2 and for the simple case that ???? = ??. You can also assume that all collisions are perfectly elastic. For full marks you need to handle the first impact (cue ball onto target ball) and secondary impacts of the balls even if both are moving, and in both cases you need to move both balls (update the positions) after any collision with side until the balls come to rest. Both balls should bounce realistically if they strike the boundaries after the impact. 2D conservation of momentum problem for an elastic collision at an angle. ???????? + ???????? = ???????? + ???????? Where ???? ???? and ???? ???? are the masses and initial velocities of the system and ????and ???? are the final velocities of the system. Again, the y-component for the velocities is always zero as we are only considering motion in the x-z plane. Note as the masses are the same, we have the vector relationship of: ???? = ???? + ???? and by consideration of the conservation of kinetic energy (perfectly elastic collision) when the masses are equal and if ???? is zero we have: ????2 = ????2 + ????2 As can be seen in Appendix C the vector can be drawn as a right-angle triangle and so the vector ???? can be easily found once you know ???? at the point of impact. See Appendix D for the full formula for collisions between moving balls and this can be used in all cases. Note: You must comment code liberally to explain your steps. The Coursework will be marked based on the following marking criteria Marking Criteria Maximum component mark Task 1: Vector maths library – to achieve high marks the library must be correct, well coded, and simple to use and be reusable. Marks are per correct function implemented (see main specification). Marks will be lost if the code is not testable so you must produce a test case. 25 Task 2 Part A: Trajectory in 3D for a projectile with restitution (sphere must bounce on landing) and the bounce must realistically correspond to change in the restitution value. This must be correct for high marks and meet all requirements. It must include the ability to change the velocity at design time. Code must be reusable e.g. for a different game object. 10 Task 3 Waypoint scene. Waypoints must be movable at design time and still be followed correctly. Motion must be continuous, and you must be able to the set the speed at design time as shown. Code must be reusable e.g., for a different number of waypoints. For maximum marks the motion around the waypoint must be implemented (there are 7 marks for this part). 15 Task 4: Part A: Vector reflection – for high marks you must take into account the dimensions of the spheres so that the bounces from the boundaries look realistic and all reflections must be correct. Dynamic friction must be applied to slow the balls down to an eventual stop. 25 Task 4 Extension: 2D conservation of momentum problem for an elastic collision at an angle. This must be mathematically correct and look realistic (balls move correctly after impact) for high marks and must meet all requirements. Secondary moving ball collisions need to be handled for maximum marks. 25 Total 100

Appendix D – Two moving ball collision formula This is the equation for calculating the final velocity of a two-ball collision where both balls are moving. This also works for the case of one moving ball (e.g. cue ball) and a second stationary ball. Apart from the masses everything here is a vector quality X1 and X2 are position vectors of the ball centres at the point of impact. The angle brackets signifies a dot product of the vectors (v1 – v2) and (X1 – X2) etc. ?? is the final velocity and ?? is the initial velocity. Note that || X2 – X1|| etc. is the magnitude of the vector subtraction X2-X1 If the masses are equal, then the mass term at the beginning reduces to be equal to 1 Appendix E – Euler method for Equation of motion Pseudo-code for Euler method for equations of motion Set up variables and constants: gravity vector, acceleration vector, initial velocity vector, initial position vector, time interval deltaT etc. Use this for all of the problems and note that for the waypoint problem the acceleration a is zero. Loop – in Unity use the Update() method . { ?? = ?? + ?? * ???????????? ?? = ???????? + ?? * ???????????? //update the objects position //check if you need to change the motion e.g. position of projectile is below zero so need to bounce etc. } Note – if noted in bold above then these are vectors quantities
