To play the game you need Python 3.9 or later installed, and you must install (with upgrades!) the packages in requirements.txt. Then run main.py in the root directory of this repo.
python3.9 -m pip install -Ur requirements.txt
python3.9 main.pyYour goal is to destroy as many enemy tanks as you can before getting destroyed yourself.
The controls are fairly simple: aim the turret with your mouse, and shoot with left click. To move, use the WASD keys.
- W will move the tank forward
- S will move the tank backward
- A will turn the tank to the left
- D will turn the tank to the right
Pressing F3 will open the debug screen
I manipulate strings in tank_game/main.py:180, where I tell the user how many seconds they survived.
178 screen.blit(rendered, dest_rect)
179
180 rendered = config.FINAL_INFO_BODY_FONT.render(f'And you survived for {global_vars.time_lasted:.3f} seconds', True, 'darkgreen')
181 dest_rect = rendered.get_rect()
182 dest_rect.x = 960 - dest_rect.centerxI use events in the event loop (tank_game/main.py:72-100) to handle clicks and key presses.
72 for event in pygame.event.get():
73 if event.type == QUIT:
74 running = False
75 elif event.type == KEYDOWN:
76 if event.key == K_w:
77 move_dir = 1
78 elif event.key == K_s:
79 move_dir = -1
80 elif event.key == K_a:
81 rotate_dir = -1
82 elif event.key == K_d:
83 rotate_dir = 1
84 elif event.key == K_F3:
85 # elif (event.key == K_f) and (event.mod & KMOD_ALT) and (event.mod & KMOD_SHIFT):
86 global_vars.debug = not global_vars.debug
87 elif event.key == K_SPACE:
88 if death_screen_open:
89 death_screen_close = True
90 elif event.type == KEYUP:
91 if event.key in (K_w, K_s):
92 move_dir = 0
93 elif event.key in (K_a, K_d):
94 rotate_dir = 0
95 elif event.type == MOUSEBUTTONDOWN:
96 if event.button == 1:
97 if death_screen_open:
98 death_screen_close = True
99 else:
100 shot_active = TrueI used a function (method actually) in tank_game/tank.py:196-217. This function calculates if a tank will collide with another tank in front (or behind) it.
196 def get_collision(self, dist: int, within: int, angle: int, tanks: list[Tank]) -> tuple[bool, float, Tank]:
197 if dist == 0:
198 return False
199 if dist > 0:
200 rel_angle = 0
201 else:
202 rel_angle = 180
203 ver_angle = angle + rel_angle
204 ver_angle_lt = (ver_angle - 45) % 360
205 ver_angle_gt = (ver_angle + 45) % 360
206 close_dist = inf
207 close_tank = None
208 for other in tanks:
209 if other is self:
210 continue
211 ang = (other.position - self.position).as_polar()[1] + 90
212 ang %= 360
213 if ver_angle_lt < ang < ver_angle_gt:
214 if (tdist := self.position.distance_squared_to(other.position)) < close_dist:
215 close_dist = tdist
216 close_tank = other
217 return close_dist <= within, close_dist, close_tank
