植物大战僵尸

功能介绍

最近一直在给这个植物大战僵尸游戏添加新的植物和僵尸, 因为网上的图片资源有限,能加的植物和僵尸比较少, 目前进展如下:

功能实现如下:

选择植物在哪里种植

植物卡片选择和种植

如图3所示,游戏中可以种植物的方格一共有45个(有5行,每行9列)。这篇文章要介绍的是:

代码实现

所有的植物卡片的名称和属性都保存在单独的list中,每个list index都对应一种植物。比如list index 0 就是太阳花:

代码在source\component\menubar.py中

card_name_list = [c.CARD_SUNFLOWER, c.CARD_PEASHOOTER, c.CARD_SNOWPEASHOOTER, c.CARD_WALLNUT, c.CARD_CHERRYBOMB, c.CARD_THREEPEASHOOTER, c.CARD_REPEATERPEA, c.CARD_CHOMPER, c.CARD_PUFFMUSHROOM, c.CARD_POTATOMINE, c.CARD_SQUASH] plant_name_list = [c.SUNFLOWER, c.PEASHOOTER, c.SNOWPEASHOOTER, c.WALLNUT, c.CHERRYBOMB, c.THREEPEASHOOTER, c.REPEATERPEA, c.CHOMPER, c.PUFFMUSHROOM, c.POTATOMINE, c.SQUASH] plant_sun_list = [50, 100, 175, 50, 150, 325, 200, 150, 0, 25, 50] plant_frozen_time_list = [0, 5000, 5000, 10000, 5000, 5000, 5000, 5000, 8000, 8000, 8000] all_card_list = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

植物卡片类

代码在source\component\menubar.py中,每个植物卡片是一个单独的Card类,用来显示这个植物。

class Card(): def __init__(self, x, y, name_index, scale=0.78): self.loadFrame(card_name_list[name_index], scale) self.rect = self.image.get_rect() self.rect.x = x self.rect.y = y self.name_index = name_index self.sun_cost = plant_sun_list[name_index] self.frozen_time = plant_frozen_time_list[name_index] self.frozen_timer = -self.frozen_time self.select = True def loadFrame(self, name, scale): frame = tool.GFX[name] rect = frame.get_rect() width, height = rect.w, rect.h self.image = tool.get_image(frame, 0, 0, width, height, c.BLACK, scale) def checkMouseClick(self, mouse_pos): x, y = mouse_pos if(x >= self.rect.x and x <= self.rect.right and y >= self.rect.y and y <= self.rect.bottom): return True return False def canClick(self, sun_value, current_time): if self.sun_cost <= sun_value and (current_time - self.frozen_timer) > self.frozen_time: return True return False def canSelect(self): return self.select def setSelect(self, can_select): self.select = can_select if can_select: self.image.set_alpha(255) else: self.image.set_alpha(128) def setFrozenTime(self, current_time): self.frozen_timer = current_time def update(self, sun_value, current_time): if (self.sun_cost > sun_value or (current_time - self.frozen_timer) <= self.frozen_time): self.image.set_alpha(128) else: self.image.set_alpha(255) def draw(self, surface): surface.blit(self.image, self.rect)

卡片栏类

代码在source\component\menubar.py中,MenuBar类显示图3中的植物卡片栏,

class MenuBar(): def __init__(self, card_list, sun_value): self.loadFrame(c.MENUBAR_BACKGROUND) self.rect = self.image.get_rect() self.rect.x = 10 self.rect.y = 0 self.sun_value = sun_value self.card_offset_x = 32 self.setupCards(card_list) def loadFrame(self, name): frame = tool.GFX[name] rect = frame.get_rect() frame_rect = (rect.x, rect.y, rect.w, rect.h) self.image = tool.get_image(tool.GFX[name], *frame_rect, c.WHITE, 1) def update(self, current_time): self.current_time = current_time for card in self.card_list: card.update(self.sun_value, self.current_time) def createImage(self, x, y, num): if num == 1: return img = self.image rect = self.image.get_rect() width = rect.w height = rect.h self.image = pg.Surface((width * num, height)).convert() self.rect = self.image.get_rect() self.rect.x = x self.rect.y = y for i in range(num): x = i * width self.image.blit(img, (x,0)) self.image.set_colorkey(c.BLACK) def setupCards(self, card_list): self.card_list = [] x = self.card_offset_x y = 8 for index in card_list: x = 55 self.card_list.append(Card(x, y, index)) def checkCardClick(self, mouse_pos): result = None for card in self.card_list: if card.checkMouseClick(mouse_pos): if card.canClick(self.sun_value, self.current_time): result = (plant_name_list[card.name_index], card.sun_cost) break return result def checkMenuBarClick(self, mouse_pos): x, y = mouse_pos if(x >= self.rect.x and x <= self.rect.right and y >= self.rect.y and y <= self.rect.bottom): return True return False def decreaseSunValue(self, value): self.sun_value -= value def increaseSunValue(self, value): self.sun_value = value def setCardFrozenTime(self, plant_name): for card in self.card_list: if plant_name_list[card.name_index] == plant_name: card.setFrozenTime(self.current_time) break def drawSunValue(self): self.value_image = getSunValueImage(self.sun_value) self.value_rect = self.value_image.get_rect() self.value_rect.x = 21 self.value_rect.y = self.rect.bottom - 21 self.image.blit(self.value_image, self.value_rect) def draw(self, surface): self.drawSunValue() surface.blit(self.image, self.rect) for card in self.card_list: card.draw(surface)

鼠标图片切换

代码在source\state\level.py中,setupMouseImage 函数实现鼠标图片切换为选中的植物

def setupMouseImage(self, plant_name, plant_cost): frame_list = tool.GFX[plant_name] if plant_name in tool.PLANT_RECT: data = tool.PLANT_RECT[plant_name] x, y, width, height = data['x'], data['y'], data['width'], data['height'] else: x, y = 0, 0 rect = frame_list[0].get_rect() width, height = rect.w, rect.h if plant_name == c.POTATOMINE or plant_name == c.SQUASH: color = c.WHITE else: color = c.BLACK self.mouse_image = tool.get_image(frame_list[0], x, y, width, height, color, 1) self.mouse_rect = self.mouse_image.get_rect() pg.mouse.set_visible(False) self.drag_plant = True self.plant_name = plant_name self.plant_cost = plant_cost def drawMouseShow(self, surface): if self.hint_plant: surface.blit(self.hint_image, self.hint_rect) x, y = pg.mouse.get_pos() self.mouse_rect.centerx = x self.mouse_rect.centery = y surface.blit(self.mouse_image, self.mouse_rect)

提示种在哪个方格中

先看下map类,代码在source\component\map.py 中

MAP_EMPTY = 0 MAP_EXIST = 1 class Map(): def __init__(self, width, height): self.width = width self.height = height self.map = [[0 for x in range(self.width)] for y in range(self.height)] def isValid(self, map_x, map_y): if (map_x < 0 or map_x >= self.width or map_y < 0 or map_y >= self.height): return False return True def isMovable(self, map_x, map_y): return (self.map[map_y][map_x] == c.MAP_EMPTY) def getMapIndex(self, x, y): x -= c.MAP_OFFSET_X y -= c.MAP_OFFSET_Y return (x // c.GRID_X_SIZE, y // c.GRID_Y_SIZE) def getMapGridPos(self, map_x, map_y): return (map_x * c.GRID_X_SIZE c.GRID_X_SIZE//2 c.MAP_OFFSET_X, map_y * c.GRID_Y_SIZE c.GRID_Y_SIZE//5 * 3 c.MAP_OFFSET_Y) def setMapGridType(self, map_x, map_y, type): self.map[map_y][map_x] = type def getRandomMapIndex(self): map_x = random.randint(0, self.width-1) map_y = random.randint(0, self.height-1) return (map_x, map_y) def showPlant(self, x, y): pos = None map_x, map_y = self.getMapIndex(x, y) if self.isValid(map_x, map_y) and self.isMovable(map_x, map_y): pos = self.getMapGridPos(map_x, map_y) return pos

代码在source\state\level.py中,

def canSeedPlant(self): x, y = pg.mouse.get_pos() return self.map.showPlant(x, y) def setupHintImage(self): pos = self.canSeedPlant() if pos and self.mouse_image: if (self.hint_image and pos[0] == self.hint_rect.x and pos[1] == self.hint_rect.y): return width, height = self.mouse_rect.w, self.mouse_rect.h image = pg.Surface([width, height]) image.blit(self.mouse_image, (0, 0), (0, 0, width, height)) image.set_colorkey(c.BLACK) image.set_alpha(128) self.hint_image = image self.hint_rect = image.get_rect() self.hint_rect.centerx = pos[0] self.hint_rect.bottom = pos[1] self.hint_plant = True else: self.hint_plant = False
