I dont know how to make a rect stand on another rect in pygame

byMR
January 13, 2022

I’m trying to make a simple 2d jumping game, I’ve made a jumping cube and a simple platform(map), collisions are working if I test it like print("collided"), but I don’t know how to make the rect stand on another rect,

tile[1] are actually all tiles (blocks) which were looped from the list called tile_list. In tile_list they are saved tiles. self.rect_img = img.get_rect() <- is the rect object i want player to stand on, but how I said, its looped through list so i need to work with tile[1]

I tried using:

MEDevel.com: Open-source for Healthcare and Education

Visit Medevel 

for tile in self.tile_list:
    collide =  tile[1].colliderect(self.player_rect.x,self.player_rect.y,PLAYER_WIDTH,PLAYER_HEIGHT)
    if collide:
        tile[1].top =  self.player_rect.bottom

But doesnt work, the player(self.player_rect), somehow pushes the second rect below it.

Also if u want to test the code, game then create 2 files, main.py and mapdata.py(which is the tilemap), and change photos

>Solution :

You need to change the player’s position instead of the block’s position and you also need to set the player’s y attribute:

self.player_rect.x = round(self.x)
self.player_rect.y = round(self.y)

for tile in self.tile_list:
    if self.player_rect.colliderect(tile[1]):
        self.player_rect.bottom = tile[1].top
        self.y = self.player_rect.y
