<\/p>\nLet’s see how to check when the mouse button is pressed. Not only we will check the mouse button on the left, but the middle one, the right one and also the when mousewheel will be pushed up or down.<\/p>\n
<\/p>\n
<\/p>\n
First<\/p>\n
import pygame\r\n\r\n# Initialize pygame and the screen\r\npygame.init()\r\npygame.font.init()\r\nmyfont = pygame.font.SysFont('Comic Sans MS', 14)\r\nclock = pygame.time.Clock() # frame rate\r\nscreen = pygame.display.set_mode((400, 400)) \r\npygame.display.set_caption('Mouse events')<\/pre>\nThen we create a little function to render the text<\/p>\n
def update_text(text, color=(0, 255, 255)):\r\n text = text.encode()\r\n mf = myfont.render(text, True, color)\r\n screen.blit(mf, (10, 10))<\/pre>\nIn the main function we start with some variable for colors, text etc.<\/p>\n
def main():\r\n c = 0\r\n tc = (c,c,c)\r\n text = \"'http:\/\/pythonprogramming.altervista.org'\"\r\n color = (255,255,255)\r\n update_text(text, color=color)\r\n loop = 1\r\n CORAL = (128,0,0)\r\n DARKGREEN = (0,255,128)\r\n COLOR = CORAL<\/pre>\nThe interesting part is the loop where we get the input of the user and we show different text for every event<\/p>\n
while loop:\r\n screen.fill(COLOR)\r\n clock.tick(60)\r\n events = pygame.event.get()\r\n update_text(text, color=color)\r\n for event in events:\r\n if event.type == pygame.QUIT:\r\n loop = 0\r\n elif event.type == pygame.MOUSEBUTTONDOWN or event.type == pygame.MOUSEBUTTONUP:\r\n if event.type == pygame.MOUSEBUTTONDOWN:\r\n action, color = \"pressed\", (0,255, 255)\r\n elif event.type == pygame.MOUSEBUTTONUP:\r\n action, color = \"released\", (255, 64, 64)\r\n if event.button == 4:\r\n print(\"MOUSEWHEEL UP\")\r\n action = \"MOUSEWHEEL UP\"\r\n COLOR = CORAL\r\n if event.button == 5:\r\n print(\"MOUSEWHEEL DOWN\")\r\n action = \"MOUSEWHEEL DOWN\"\r\n COLOR = DARKGREEN\r\n\r\n\r\n text = f'button {event.button} {action} in the position {event.pos}'\r\n print(text)\r\n pygame.display.update()\r\n pygame.quit()<\/pre>\nThis is the whole code:<\/p>\n
