Description
For this assignment you will zip and submit the entire ‘src’ folder of the
assignment. You are *NOT* allowed to add any files in addition to the ones
already in the src folder from the assignment zip file. This means that you
will not be submitting ANY changes you have made to the visual studio project,
if you used it for development.
YOU MUST INCLUDE THE FOLLOWING INFO IN A COMMENT AT THE TOP OF main.cpp:
– ALL students’ full names, cs usernames, and student numbers
– If you did not get a specific feature to work, please explain what you tried
to do to get it to work, and partial marks may be given for effort.

Program Specification
——————————————————————————-
In this assignment you will be writing the game that was presented in class.
This game must have the following features:
Player:
– The player is represented by a shape which is defined in the config file
– The player must spawn in the center of the screen at the beginning of the
game, and after it dies (collides with an enemy)
– The player moves by a speed read from the config file in these directions:
Up: W key, Left: A key, Down: S key, Right: D key
– The player is confined to move only within the bounds of the window
– The player will shoot a bullet toward the mouse pointer when the left mouse
button is clicked. The speed, size, and lifespan of the bullets are read
from the config file.
– You are free to come up with your own ‘special move’ which is fired by
the player when the right mouse button is clicked. This special move must
consist of more than one bullet which travels in an interesting way. The
properties of the special move are not in the config file.
Enemy(s):
– Enemies will spawn in a random location on the screen every X milliseconds,
where X is defined in the configuration file. Enemies must not overlap
the sides of the screen at the time of spawn.
– Enemies shapes have random number of vertices, between a given minimum and
maximum number, which is specified in the config file.
– Enemy shape radius will be specified in the configuration file.
– Enemies will be given a random color upon spawning.
– Enemies will be given a random speed upon spawning, between a minimum and
maximum value specified in the config file.
– When (large) enemies collide with a bullet or player, they are destroyed,
and N small enemies spawn in its place, where N is the number of vertices
of the original enemy. Each small enemy must have the same number of
vertices and color of the original enemy. These small entities travel
outward at angles at a fixed intervals equal to (360 / vertices).
For example, if the original enemy had 6 sides, the 6 smaller enemies will
travel outward in intervals of (360/6) = 60 degrees.
Score:
– Each time an enemy spawns, it is given a score component of N*100, where N
is the number of vertices it has. Small enemies get double this value.
– If a player bullet kills an enemy, the game score is increased by the score
component of the enemy killed.
– The score should be displayed with the font specified by the config file in
the top-left corner of the screen.
Drawing:
– In the render system, all entities should be given a slow rotation, which
makes the game look a little nicer.
– Any special effects which do not alter game play can be added for up to
5% bonus marks on the assignment. Note that assignments cannot go above
100% total marks, but the 5% bonus can overwrite any marks lost in other
areas of the assignment.
– Any Entity with a lifespan is currently alive, it should have its Color
alpha channel set to a ratio depending on how long it has left to live.
For example, if an Entity has a 1000ms life span, and it has been alive for
500ms, its alpha value should be set to 0.5 * 255. This ratio should go from
255 when it is first spawned, to 0 on the last frame it is alive.
Misc:
– The ‘P’ key should pause the game
– The ‘ESC’ key should close the game
Configuration File:
The configuration file will have one line each specifying the window size,
font format, player, bullet specification, and enemy specifications.
Lines will be given in that order, with the following syntax:
Window W H FL FS
– This line declares that the SFML Window must be constructed with width W
and height H, each of which will be integers. FL is the frame limit that the
window should be set to, and FS will be an integer which specifies whether to
display the application in full-screen mode (1) or not (0).
Font F S R G B
– This lines defines the font which is to be used to draw text
for this program. The format of the line is as follows:
Font File F std::string (it will have no spaces)
Font Size S int
RGB Color (R,G,B) int, int, int
Player Specification:
Player SR CR S FR FG FB OR OG OB OT V
Shape Radius SR int
Collision Radius CR int
Speed S float
Fill Color FR,FG,FB int,int,int
Outline Color OR,OG,OB int,int,int
Outline Thickness OT int
Shape Vertices V int
Enemy Specification:
Enemy SR CR SMIN SMAX OR OG OB OT VMIN VMAX L SI
Shape Radius SR int
Collision Radius CR int
Min / Max Speed SMIN,SMAX float, float
Outline Color OR,OG,OB int,int,int
Outline Thickness OT int
Min/Max Vertices VMIN,VMAX int,int
Small Lifespan L int
Spawn Interval SI int
Bullet Specification:
Bullet SR CR S FR FG FB OR OG OB OT V L
Shape Radius SR int
Collision Radius CR int
Speed S float
Fill Color FR,FG,FB int,int,int
Outline Color OR,OG,OB int,int,int
Outline Thickness OT int
Shape Vertices V int
Lifespan L int

Assignment Hints
——————————————————————————-
I recommend approaching this assignment in the following order:
0. Save the configuration file reading until after gameplay implemented
1. Implement the Vec2 class, which you will use for all Components
Test the Vec2 class by creating some in main() and printing operator results
2. Updated: The EntityManager class has been implemented for you
If you want, you can try to make it more efficient
3. Implement basics the Game class:
a. Construct a player Entity using the spawnPlayer() function
b. Implement basic drawing of entities using the Game::sRender() function
c. Construct some enemies using the spawnEnemy() function
d. Construct a bullet using the spawnBullet() function
4. Implement Player Movement in Game::sUserInput and Game::sMovement
5. Implement collisions in sCollision and entity->destroy() if it should die
6. Implement the rest of the game’s functionality, including config file readinga
